Answer: 24

Step-by-step explanation:

Using proportions we can find,

6. The weight of the adult bear = 750 pounds.

7. The measure of each angles are: 10°, 75° and 95°

In general, the term "proportion" refers to a part, share, or amount that is compared to a whole.

According to the definition of proportion, two ratios are in proportion when they are equal. Two ratios or fractions are equal when an equation or a declaration to that effect is utilized.

Here in the question,

The weight is in the ratio = 3:1000

The average birth weight = 12 ounces = 3/4 pounds.

Now the weigh of adult bear = 1000 × 3/4 = 750 pounds.

In the second part the angles are in the ratio, 2:15:19.

So, 2x+ 15x + 19x = 180

x = 180/36

x = 5

Hence, the measure of each angles are: 10°, 75° and 95°

The equation is now in the standard shape of a hyperbola, as per the provided assertion. [(x - h)² / a²] - [(y - k)² / b²] = 1

A curve formed by the junction of a double right-angled cone and a plane that slices one half of the cone. a plane curve produced by a point so mobile that the difference between its distance from two fixed locations is a constant.

To complete the square for the given equation, we will group the x and y terms and complete the square separately for each.

4x² + 24x - 9y² + 18y - 9 = 0

4(x² + 6x) - 9(y² - 2y) = 9

4(x² + 6x + 9 - 9) - 9(y² - 2y + 1 - 1) = 9

4(x + 3)² - 9(y - 1)² = 36

Dividing by 36, we get:

(x + 3)² / 9 - (y - 1)² / 4 = 1

So, the equation is now in the standard form of a hyperbola:

[(x - h)² / a²] - [(y - k)² / b²] = 1

where h and k are the coordinates of the center, a is the distance from the center to the vertices along the x-axis, b is the distance from the center to the vertices along the y-axis, and the slope of the asymptotes is b/a.

Comparing with the standard form, we can see that:

h = -3, k = 1, a = 3, b = 2, and the slope of the asymptotes is b/a = 2/3.

The center is (-3, 1). The hyperbola opens horizontally, and its vertices are located at (-3 + a, 1) and (-3 - a, 1). So, the vertices are (-6, 1) and (0, 1).

The asymptotes are two straight lines passing through the center with a slope of ±(b/a) = ±2/3. So, the equations of the asymptotes are y - 1 = (2/3)(x + 3) and y - 1 = -(2/3)(x + 3), which simplify to y = (2/3)x + 5/3 and y = -(2/3)x + 1/3.

The distance between the center and the foci is c = sqrt(a² + b²) = √(13). The foci are located at (-3 + c, 1) and (-3 - c, 1). So, the foci are approximately (-0.16, 1) and (-5.84, 1).

The graph of the hyperbola looks like two mirrored U-shaped curves, with the vertices being the endpoints of the transverse axis.

The asymptotes intersect at the center and divide the hyperbola into four parts, called branches. The foci are located on the transverse axis, inside the branches.

The probability of both gumballs not being red is 11/21.

What is the probability?

The probability of the first gumball not being red is:

P(first gumball not red) = P(blue) + P(yellow)

= (6/15) + (5/15)

= 11/15

After removing the first gumball, there are 14 gumballs left in the bag. The probability of the second gumball not being red depends on what color the first gumball was.

Case 1: The first gumball was blue

If the first gumball was blue, there are 5 blue, 4 red, and 5 yellow gumballs left in the bag. The probability of the second gumball not being red is:

P(second gumball not red | first gumball was blue) = P(blue or yellow)

= P(blue) + P(yellow)

= (5/14) + (5/14)

= 5/7

Case 2: The first gumball was yellow

If the first gumball was yellow, there are 6 blue, 4 red, and 4 yellow gumballs left in the bag. The probability of the second gumball not being red is:

P(second gumball not red | first gumball was yellow) = P(blue or yellow)

= P(blue) + P(yellow)

= (6/14) + (4/14)

= 5/7

The probability of both gumballs not being red is the product of the probabilities of each event:

P(both gumballs not red) = P(first gumball not red) * P(second gumball not red | first gumball not red)

P(both gumballs not red) = (11/15) * (5/7)

P(both gumballs not red) = 55/105

P(both gumballs not red) = 11/21

Therefore, the probability of both gumballs not being red is 11/21.

The interest earned by the $300 savings account is $90, and the total balance at the end of 5 years is $390.

A check register balance is the amount of money in a bank account, as recorded by the account holder in their check register, after accounting for deposits, withdrawals, and fees.

1)

The check register balance is not correct. To find the correct balance, we need to adjust the statement ending balance for the outstanding deposits, subtract the outstanding check and service charge, and add any other transactions that may have been missed.

Adjusted balance for outstanding deposits: $41.27 + $27.70 + $12.30 + $102.43 = $183.70

Adjusted balance for outstanding deposits minus the outstanding check: $183.70 - $10.98 = $172.72

Adjusted balance for outstanding deposits minus the outstanding check minus the service charge: $172.72 - $5.82 = $166.90

Therefore, the correct check register balance is $166.90.

2)
To find the balance of the savings account after various time periods, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the balance after time t

P = the principal (initial deposit)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period (in years)

For this problem, we have:

P = $500

r = 0.04

n = 4 (compounded quarterly)

t = 0.25 (3 months), 0.5 (6 months), 0.75 (9 months), 1 (1 year)

After 3 months:

A = $500(1 + 0.04/4)^(4*0.25) = $510.08

After 6 months:

A = $500(1 + 0.04/4)^(4*0.5) = $520.40

After 9 months:

A = $500(1 + 0.04/4)^(4*0.75) = $531.07

After 1 year:

A = $500(1 + 0.04/4)^(4*1) = $542.50

Therefore, the balance of the savings account after 3 months is $510.08, after 6 months is $520.40, after 9 months is $531.07, and after 1 year is $542.50.


3)
To find the interest earned and total balance at the end of each year, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the balance after time t

P = the principal (initial deposit)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period (in years)

For this problem, we have:

P = $1000

r = 0.08

n = 1 (compounded annually)

t = 1 (year)

After year 1:

Interest earned = $1000 x 0.08 = $80

Total balance = $1000 + $80 = $1080

After year 2:

Interest earned = $1080 x 0.08 = $86.40

Total balance = $1080 + $86.40 = $1166.40

After year 3:

Interest earned = $1166.40 x 0.08 = $93.31

Total balance = $1166.40 + $93.31 = $1259.71

Therefore, the interest earned in year 1 is $80, the total balance at the end of year 1 is $1080, the interest earned in year 2 is $86.40, the total balance at the end of year 2 is $1166.40, and the interest earned in year 3 is $93.31, and the total balance at the end of year 3 is $1259.71.

4)

We can use the formula for compound interest to calculate the interest earned and total balance at the end of each year for each savings account:

$100 at 7% for 4 years:

P = $100, r = 0.07, n = 1 (compounded annually), t = 4

Interest earned = $100 x 0.07 x 4 = $28

Total balance = $100 + $28 = $128 after 4 years

$500 at 8% for 3 years:

P = $500, r = 0.08, n = 1 (compounded annually), t = 3

Interest earned = $500 x 0.08 x 3 = $120

Total balance = $500 + $120 = $620 after 3 years

$300 at 6% for 5 years:

P = $300, r = 0.06, n = 1 (compounded annually), t = 5

Interest earned = $300 x 0.06 x 5 = $90

Total balance = $300 + $90 = $390 after 5 years

Therefore, the interest earned by the $100 savings account is $28, and the total balance at the end of 4 years is $128.
The interest earned by the $500 savings account is $120, and the total balance at the end of 3 years is $620.
The interest earned by the $300 savings account is $90, and the total balance at the end of 5 years is $390.

4 number was not used in the statement. we can use -3 as the other value.

A simple statement is a single assertion that can be classified as true or false, while a compound statement is formed by combining two or more simple statements using logical operators such as "and", "or", and "not".

To explain the statement mathematically:

First, we evaluate N/N:

N/N = 1

Next, we simplify the inequality using this value:

1•N < N - 1 < N - N

Simplifying further, we get:

N < N - 1 < 0

We can then substitute the values of -4 to 4 for N and see which value(s) satisfy the inequality.

If N = -4, then we have:

-4 < -5 < 0

This is true, so we can use -4 as one of the values.

If N = -3, then we have:

-3 < -4 < 0

This is also true, so we can use -3 as the other value.

Therefore, the completed statement is:

-4/-4 • -4 < -4 - (-4/-4) < -4 + 4/-4 <br>

The solutions to the quadratic equations are as follows

4a. The rocket was launched from an initial height of 10 meters.

b. The maximum height of the rocket was 55 meters.

c. The rocket reaches its maximum height at 3 seconds

d. the rocket is in the air for t = 6.316 seconds

5. when the horizontal distance is 1 foot, the height of the balloon is 8.875 feet

b. when the horizontal distance is 33 feet, the height of the balloon is 0.875 feet.

The function is a quadratic equation, and here is how we solve each problem;

a. The initial height of the rocket is the value of h when t=0. So we substitute t=0 into the equation to find:

h = -5(0)² + 30(0) + 10 = 10 meters

b. & c. The maximum height of a projectile launched upward occurs at the vertex of the parabola represented by the quadratic function. For a quadratic function in the form y = ax² + bx + c, the time at which the maximum (or minimum) occurs is -b/2a. In this case, a = -5 and b = 30. So:

t = -b/2a = -30 / (2×-5) = 3 seconds

So, the rocket reaches its maximum height at t=3 seconds. We can find this maximum height by substituting t=3 into the equation:

h = -5(3)² + 30(3) + 10 = -5×9 + 90 + 10 = 45 meters

The rocket is in the air from the time it was launched until it hits the ground. The time when it hits the ground is when h = 0. So we can set the equation to 0 and solve for t:

0 = -5t² + 30t + 10

This is a quadratic equation and can be solved using the quadratic formula: t = [-b ± √(b² - 4ac)] / (2a)

Let's calculate the roots:

t = [-30 ± √((30)² - 4×-5×10)] / (2×-5)

= [-30 ± √(900 + 200)] / -10

= [-30 ± √(1100)] / -10

= 6.316 or -0.32

5. a. To find the height of the balloon when d=1, we substitute d=1 into the equation:

h = -1/8(1)²+ 4(1) + 5 = -1/8 + 4 + 5 = 8.875 feet

b. To determine whether the balloon hits your enemy, we need to see if the balloon's height (h) is above ground level (h > 0) when d=33. So, we substitute d=33 into the equation:

h = -1/8(33)² + 4(33) + 5

h = -1/8×1089 + 132 + 5

h = -136.125 + 132 + 5

h = 0.875 feet

when the horizontal distance is 33 feet, the height of the balloon is 0.875 feet. This means the balloon is above ground level and therefore would indeed hit your nemesis standing 33 feet away.

the point that would not be found on the line is option A, (-7,19).

How to calculate the line?

We can use the equation of the line that passes through these three points to determine which of the given points would not be on the line.

First, we can find the slope of the line using the first two points:

slope = (y₂ - y₁)/(x₂- x₁) = (4 - 9)/(-1 - (-3)) = 5/2

Now, we can use the point-slope form of the equation of a line with the slope we just found and the first point (-3,9):

y - y₁= m(x - x₁)

y - 9 = (5/2)(x + 3)

Simplifying this equation gives us:

y = (5/2)x + (27/2)

We can check that the third point (1,-1) also lies on this line by plugging in the values of x and y into the equation above.

Now, we can check which of the given points would not be on this line by plugging in the values of x and y into the equation above.

A. (-7,19): y = (5/2)(-7) + (27/2) = 5.5, which does not equal 19, so this point is not on the line.

B. (7,-16): y = (5/2)(7) + (27/2) = 22.5, which does not equal -16, so this point is not on the line.

C. (-8,20.5): y = (5/2)(-8) + (27/2) = 4.5, which does not equal 20.5, so this point is not on the line.

D. (8,-18.5): y = (5/2)(8) + (27/2) = 25.5, which does not equal -18.5, so this point is not on the line.

Answer:

Step-by-step explanation:

The surface area of a sphere is given by the formula:

S = 4πr^2

where S is the surface area and r is the radius of the sphere.

We are given that the surface area of the sphere is 60 square feet. Using the formula above, we can solve for the radius:

60 = 4πr^2

Dividing both sides by 4π, we get:

15/π = r^2

Taking the square root of both sides, we get:

r = sqrt(15/π)

Using 3.14 as an approximation for π, we can evaluate this expression:

r ≈ sqrt(15/3.14)

r ≈ 2.20

Perimeter of the square base = 4 x side length

48 inches = 4 x side length

Side length = 12 inches

Now we can find the area of the base:

Area of the base = side length squared

Area of the base = 12 inches x 12 inches

Area of the base = 144 square inches

Next, we need to find the area of each triangular face. To do this, we need to find the length of the slant height of the pyramid. We can use the Pythagorean theorem to do this:

Slant height squared = height squared + (1/2 base length) squared

Slant height squared = 8 inches squared + (6 inches) squared

Slant height squared = 64 inches squared + 36 inches squared

Slant height = square root of (64 + 36) inches

Slant height = 10 inches

Now we can find the area of each triangular face:

Area of a triangular face = (1/2 base length) x slant height

Area of a triangular face = (1/2 x 12 inches) x 10 inches

Area of a triangular face = 60 square inches

Finally, we can add the area of the base and the area of the four triangular faces together to find the total surface area of the pyramid:

Total surface area = Area of the base + (4 x Area of a triangular face)

Total surface area = 144 square inches + (4 x 60 square inches)

Total surface area = 384 square inches

Therefore, the surface area of the pyramid is 384 square inches.

In the above proportions problem, note that the distance of PR is 155.17ft.

To solve for PR, note that

OC/RE = PR/OR

That is:

225/145 = PR/100

To solve for PR, we can cross-multiply the fractions:

225 * 100 = 145 * PR

22,500 = 145PR

Dividing both sides by 145:

PR = 155.17

Therefore, PR is approximately 155.17ft
