I don’t remember how to do this

For this case, what we must do is solve the following system of equations:  tan (50) = h / x  tan (40) = h / (x + 50)  

Solving the system we have:  (x + 50) * tan (40) = h  (x) * tan (50) = h  

Matching:  (x + 50) * tan (40) = (x) * tan (50)  

Rewriting:  x (tan (50) - tan (40)) = 50 * tan (40)  x = 50 * tan (40) / (tan (50) - tan (40))  x = 118.9692621  

Substituting:  h = (x) * tan (50)  h = (118.9692621) * tan (50)  h = 141.7820455

Answer:

See answers below for explanations (answers are in bold)

Step-by-step explanation:

Problem 1 (Top left):

Assuming that the shape is an ellipse, we will use the formula A=πab where a and b are both half the major and minor axis respectively. Since a=9 and b=6, then we have A = π(9)(6) = 54π = 169.646 units^2 as our final answer

Problem 2 (Top right):

Again, we use the same equation as in Problem 1 but this time, a=12 and b=8, so we then have A = π(8)(12) = 96π = 301.593 units^2 as our final answer

Problem 3 (Bottom left):

We can make this irregular shape into a half-ellipse and a rectangle. We would find their separate areas and add them up. The area of the half-ellipse would be A=1/2πab. The value of "a" would be 13.8/2=6.9 since that's the length of the rectangle. The value of "b" would be 3.5, so that means the area of the half-ellipse would be A = 1/2(π)(6.9)(3.5) = 12.075π = 37.935 units^2.  The width and length of the rectangle are 5.4 and 13.8 respectively, so this means the area of the rectangle is 5.4*13.8 = 74.52 units^2. Combining both areas, we get 37.935+74.52 = 112.455 units^2 as our final answer

Problem 4 (Bottom right):

This irregular shape is an ellipse, but a circle is missing from its center. Thus, we must find the area of the circle and ellipse and then subtract the circle's area from the ellipse's area. For the area of the ellipse, a=(15.5/2)=7.75, and b=(7/2)=3.5, making its area A = π(7.75)(3.5) = 27.125π = 85.216 units^2. The area of a circle is A=πr² where "r" is the radius. The radius would be 7/2=3.5, making the circle's area A = π(3.5²) = 12.25π = 38.485 units^2. This means that the shaded area is 85.216-38.435 = 46.781 units^2  

Answer:

40,000

Step-by-step explanation:

Given that:

Percentage Cost price of jewelry = 100%

Jewelery was sold at loss of 5% = (100%- 5%) = 95%

If sold at 5200 more ; profit made = 8%

That is ; (100% + 8%) = 108%

Difference between loss percentage and profit percentage = change in price sold

(108% - 95%) = 5200

13% = 5200

If ;

0.13 = 5200

The percentage cost price = 100% will be;

0.13 = 5200

1 = x

0.13x = 5200

x = 5200 / 0.13

x = 40,000

the constant inequality of my life, always close but never there

Answer:

a

Step-by-step explanation:

Answer:

p = 2

Step-by-step explanation:

p + 4/p - 4

multiplying through by p,

p×p + 4/p ×p - 4×p

p² + 4 - 4p = 0

p² - 4p + 4 = 0

factorizing,

p(p - 2) -2(p - 2) =0

(p -2)(p -2) =0

p-2 =0

p=2

Answer:

C) Explain how the equations are equal and just prove it with a check or just plug in a number like for ex: x=1 and I checked with both and it equals out.

d) Use inverse operations (or you can say do the order of operations in reverse and then use invers operations), provide an example if you think what you said doesn’t make sense, like for

Ex: 2x-1=43+5x

     2x=44+5x (add the -1)

     -3x=44  (subtract 5x to both sides)

       X=44/-3 (isolate the variable by dividing 3 on both sides)

An example is always better

E) Just use inverse operations and solve it like what you would normally do

Step-by-step explanation:

Given that:

Total length of ribbon present with Billy = 2.4 m

This ribbon is to be shared with 12 friends evenly.

Billy is doing this work of making craft for the past many years.

To find:

How many centimeters of ribbon that 7 friends will get?

Solution:

First of all, let us find out what length of ribbon will each person get.

Length of ribbon to be shared with each person = Total length of ribbon divided by total number of persons

Length of ribbon to be shared with each person = [tex]\frac{2.4}{12} = 0.2\ m[/tex]

Now, The length of ribbon that 7 friends will get = 7 [tex]\times[/tex] 0.2 = 1.4 m

1 m = 100 cm

1.4 m = 1.4 [tex]\times[/tex] 100 cm = 140 cm

Step 2: Solve for x

Answer:

The number is 66

Step-by-step explanation:

Since 44 is two thirds of a number, 44/x = 2/3

If you multiply the numerator and denominator of 2/3 by 22, you get 44/66

Since 44/x = 44/66,

x=66

If 44 is 2 thirds of a number, then the number is 77.

We can solve this problem by setting up the following equation:

2/3 * x = 44

Where x is the unknown number.

To solve for x, we can multiply both sides of the equation by 3/2. This gives us the following equation:

x = 44 * (3/2)

Simplifying the right side of the equation, we get x = 77.

Therefore, the number is 77.

Here is the solution in more detail:

Define the variables.

x: The unknown number.

Set up the equation.

We know that 2/3 of the number is 44, so we can set up the equation 2/3 * x = 44.

Solve for x.

To solve for x, we can multiply both sides of the equation by 3/2. This gives us the equation x = 44 * (3/2).

Simplifying the right side of the equation, we get x = 77.

The answer.

Therefore, the number is 77.

Answer:

32 seniors, 41 adults, and 23 children were admitted.

Step-by-step explanation:

To make things a bit simpler, we can represent all three kinds of tickets in terms of one variable, [tex]x[/tex]. Let the number of senior visitors be [tex]x[/tex]. Then, since 9 more adults were admitted as compared to the seniors, we can let the number of adult visitors be [tex]x+9[/tex]. Therefore, since there were 96 visitors in total, we know that the number of child visitors is 96 subtracted by the total number of adult and senior visitors. The total number of adult and senior visitors is [tex]x+x+9=2x+9[/tex]. Thus, the number of child visitors is [tex]96-(2x+9)=96-2x-9=-2x+87[/tex].

Now, all we have to do is write an equation to solve for [tex]x[/tex]. Since senior admission costs $3, we can represent the money earned from it as [tex]3*x=3x[/tex]. Since adult admission costs $8, we can represent the money earned from it as [tex]8*(x+9)=8x+72[/tex]. Finally, since child admission costs $5, we can represent the money earned from it as [tex]5*(-2x+87)=-10x+435[/tex]. Since we know that the zoo collected $539 in total, we can write the following equation to solve for x:

[tex]3x + 8x+72-10x+435=539[/tex]

[tex]x+507=539[/tex] (Simplify LHS)

[tex]x=32[/tex] (Subtract 507 from both sides)

Therefore, 32 seniors were admitted. Since [tex]x=32, x+9=32+9=41[/tex], so 41 adults were admitted, and finally, since [tex]x=32,-2x+87=-2*32+87=-64+87=23[/tex], so 23 children were admitted. Hope this helps!

Answer:

The answer is B.

Step-by-step explanation:

The standard error (SE) of a statistic (usually an estimate of a parameter) is the standard deviation of its sampling distribution.

Formula of the standard error of the means is standard deviation divided by square root of the sample size.

SE = δ/√n

This formula also gives the standard deviation of the sample means.

The answer is standard deviation of the sample (B).

For example, "The notation for standard error can be any one of SE, SEM (for standard error of measurement or mean)."

[tex]r = -2[/tex]

Step-by-step explanation:

Given

[tex]-2.5 < r < 7[/tex]

Required

Determine the smallest value or r

For an inequality [tex]a < r < b[/tex]

The smallest value is represented as:

[tex]r>a[/tex]

In this case:

[tex]a = -2.5[/tex]

[tex]b = 7[/tex]

So:

[tex]r>a[/tex] becomes

[tex]r > -2.5[/tex]

r > -2.5 implies that the value of r is greater than -2.5

The smallest integer value after -2.5 is -2

Hence, the smallest value of r in this case is:

[tex]r = -2[/tex]

Given:

Consider the three point of second line are S, R, V instead of S, R, W.

A line with points T, R, W intersects a line with points S, R, V at point R. Another line extends from point R to point U between angle T, R, V.

[tex]\angle VRW=(3x)^\circ[/tex]

[tex]\angle TRS=(2x+18)^\circ[/tex]

To find:

The m∠SRW.

Solution:

The figure according to the given information is shown below (not to scale).

From the below figure it is clear that, [tex]\angle VRW[/tex] and [tex]\angle TRS[/tex] are vertically opposite angles. So, their measures are equal.

[tex]3x=2x+18[/tex]

Subtract 2x from both sides.

[tex]3x-2x=18[/tex]

[tex]x=18[/tex]

Using x=18 the measure of angle VRW is

[tex]\angle VRW=(3x)^\circ[/tex]

[tex]\angle VRW=(3\times 18)^\circ[/tex]

[tex]\angle VRW=54^\circ[/tex]

Now,

[tex]\angle VRW+\angle SRW=180^\circ[/tex]       [Linear pair]

[tex]54^\circ+\angle SRW=180^\circ[/tex]

[tex]\angle SRW=180^\circ-54^\circ[/tex]

[tex]\angle SRW=126^\circ[/tex]

Therefore, the correct option is C.
