Answer:
x = 13/15
Step-by-step explanation:
If x - 1/5 = 2/3,
you can find x by doing 2/3 + 1/5.
2/3 = 10/15
1/5 = 3/15
10/15 + 3/15 = 13/15!
Hope this helps! Happy Holidays! XD

El fin de semana Mara fue con su mamá a la tienda de mascotas a comprar una
pecera. Eligió una de 40, 40 y 25 cm de altura. También compraron un filtro,
piedras de colores y plantas. Una vez que llenaron la pecera, se dieron cuenta de
que el lugar donde la colocaron no era adecuado y decidieron moverla. Pesaba
demasiado, así que la tomaron de abajo. Pero inesperadamente las paredes se
rompieron y se quedaron con la base de la pecera en las manos.
a) ¿Cuál era la capacidad de la pecera en litros?
b) ¿Por qué se rompieron las paredes y no la base?
c) Si la fuerza de la presión del agua sobre las paredes de la pecera fuera 20N, y
la superficie de la pared de 0.20m 2 , ¿cuál es la presión?

Answer:
y - 13 = -2(x+7)
Step-by-step explanation:
Given
Coordinate point (-7, 13)
Slope m = -2
We can express the euation of the line in point slope form as shown;
The point slope form of the equation is expressed as;
y - y0 = m(x-x0)
x0 = -7, y0 = 13 and m = -2
Substitute;
y - 13 = -2(x-(-7))
y - 13 = -2(x+7)
Hence the required equation in point- slope form is y - 13 = -2(x+7)

Which of the following conditions alone would guarantee that those two events are mutually exclusive?
a. Sales each month are statistically independent of each other.
b. Sales each month are not statistically independent of each other.
c. Available inventory prevents sales for January and February combined from exceeding $1.5 million.
d. In any given month the probability of sales exceeding $1 million is less than 50%. The expected sales in January is more than the expected sales in February.
e. None of the above.
Answer:
d. In any given month the probability of sales exceeding $1 million is less than 50%. The expected sales in January is more than the expected sales in February.
Step-by-step explanation:
The above condition about the probability of sales exceeding $1 MILLION BEING LESS THAN 50% would guarantee that.

A Jewelry artist is selling at an fair. It costs $135 to rent a booth at the fair. The cost of materials for each necklace is $4.00. The artist is selling the necklaces at $12 each.
The inequality 12n>145+4n represents the situation in which the artist a profit.
Answer:
a) Since the income is more than the cost, she makes a profit.
b) To make profits, she must sell at least 17 necklaces
Step-by-step explanation:
Inequalities
The costs of selling jewelry at a fair are $135 to rent a booth and $4 for each necklace. The cost function is:
C(n) = 135 + 4n
Where n is the number of necklaces she sells at the fair. She sells each necklace at $12 each, thus the income function is:
R(n) = 12n
a) If she sells n=17 necklaces, it will cost:
C(17) = 135 + 4*17 = 203
And the income is:
R(17) = 12*17= 204
Since the income is more than the cost, she makes a profit.
b) To make a profit R(n) > C(n), thus:
12n > 135 + 4n
Subtracting 4n:
8n > 135
n > 135/8
n > 16.875
Thus, to make profits, she must sell at least 17 necklaces

Which half of the unit circle satisfies the trigonometric inequality cos Ø >0? Assume that ø is the angle made by the
positive x-axis and a ray from the origin.
O the top half
O the bottom half
O the right half
O the left half
Answer:
the right half
Step-by-step explanation:
We know that cosine is a pair function.
This means that:
Cos(a) = Cos( -a)
We also know that:
Cos(pi) = 0
then:
Cos(-pi) = 0
pi and -pi are located in the y-axis, so from this we can know that the cosine function will be always positive on the right side, or in the left side, we can discard the other two options.
Now, we also know that cos(0) = 1.
And:
-pi < 0 < pi
So the two zeros are at the y-axis, and we know that cos(0) is positive (the angle 0 would be on the positive side of the x-axis, at the right), then all the right side must be positive.
Then the correct option is:
the right half
Answer:
C - The right half

Anyone know the answer to this
Answer:
x=112
Step-by-step explanation:
First, let's get all of the fractions to a common denominator.
Based on the numbers given (8,56, and 7), let's make all of the denominators be 56
for [tex]\frac{-7}{8} x[/tex], multiply the numerator and denominator by 7.
[tex]\frac{-7x}{8}[/tex]×[tex]\frac{7}{7}[/tex]= [tex]\frac{-49}{56} x[/tex]
we can leave [tex]\frac{-5}{56}x[/tex] as it is
and for [tex]\frac{1}{7} x[/tex], we cam multiply the numerator and denominator by 8
[tex]\frac{1x}{7}[/tex]×[tex]\frac{8}{8}[/tex]=[tex]\frac{8x}{56}[/tex]
Here's the equation now:
[tex]\frac{-49x}{56}[/tex]-[tex]\frac{5x}{56}[/tex]+[tex]\frac{8x}{56}[/tex]=-92
now simlify the fractions
numerators:
-49x-5x+8x=-46x
here's the fraction now:
[tex]\frac{-46x}{56}[/tex]=-92
We can simplify the fraction by 2 so it's [tex]\frac{-23x}{28}[/tex]
[tex]\frac{-23x}{28}[/tex]=-92
now multiply both sides by [tex]\frac{28}{-23}[/tex], which is the reciprocal of [tex]\frac{-23}{28}[/tex] (to isolate the variable)
[tex]\frac{28}{-23}[/tex]×[tex]\frac{-23x}{28}[/tex]=-92×[tex]\frac{28}{-23}[/tex]
[tex]\frac{-92*28}{-23}[/tex]
x=112
Hope this helps!
Answer:
x = 112
Step-by-step explanation:
The common denominator is 56 because 8*7 is 56
[tex]-\frac{7*7*x}{8*7} -\frac{5*x}{56}+\frac{8*x}{56} = - 92 \\-\frac{49*x}{56} -\frac{5*x}{56}+\frac{8*x}{56} = - 92 \\\frac{-46*x}{56}=-92[/tex]
Multiply both sides by 56
-46*x = -92 * 56
-46*x = -5152
Divide by - 46
x = -5152/-46
x = 112

What is Parabola?Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve. The topic of conic sections includes parabola, and all of its principles are discussed here.
Given:
Suppose the equation of parabolic mirror is y² = 4ax.
The given data in the is x = 1 and y = 2
So, the value is y² = 4ax
4 = 4 a (1)
a = 1
So x = 1
and, the focus is at (x, y) is (1,0).

Step-by-step explanation:
which signs do you have to fill in between the numbers to make this a true equation?
2802 1811 123 441 3633 ⅓ 32² 205
Answer:
Multiplication signs are filled in between the numbers to make it a true equation.
Step-by-step explanation:
In mathematics, a true equation occurs when the values on both sides of the equal sign (i.e. =) are the same. For example, 2 + 2 = 4 is a true equation; and 3 * 2 = 6 is a true equation.
For this question, multiplication signs are filled in between the numbers to make it a true equation as follows:
2802 * 1811 * 123 * 441 * 3633 * ⅓ * 32² * 205 = 69,972,637,305,761,000,000

Complete Question:
Write an equation that represents the relationship between <FCB and <GBC
Answer:
m<FCB = m<GBC
Step-by-step explanation:
Given that GE is parallel to HF, and AD crosses both, thus:
<FCB and <GBC are alternate interior angles.
Alternate interior angles are congruent.
Therefore, the equation that represents the relationship between <FCB and <GBC would be:
m<FCB = m<GBC
Write the equation for the perpendicular bisector of a segment that has endpoints (1, –4) and (3, 2).
Question 3 options:
A)
y = –3x – 1
B)
y = –3x + 5
C)
y = 3x + 5
D)
y = –1∕3x – 1∕3
Answer:
D. The m of the segment is 3, perpendicular slope is -1/3 bc their slope product is -1.
The equation of the perpendicular bisector of the segment with endpoints (1, -4) and (3, 2) is y = (-1/3)x - 1/3. The correct option is D.
How to calculate the equation of the line?To find the equation of the perpendicular bisector of a segment, we need to first find the midpoint of the segment.
The midpoint of the segment with endpoints (1, -4) and (3, 2) is:
[tex](\dfrac{(1+3)}{2} , \dfrac{(-4+2)}{2}) = (2, -1)[/tex]
Now we need to find the slope of the line passing through the two endpoints, which is:
[tex]m = \dfrac{(2 - (-4))} { (3 - 1)} = 3[/tex]
The slope of the perpendicular bisector will be the negative reciprocal of the slope of the segment. So the slope of the perpendicular bisector is:
m = -1/3
Finally, we can use the point-slope form of a line to find the equation of the perpendicular bisector, using the midpoint we found:
y - (-1) = (-1/3)(x - 2)
y + 1 = (-1/3)x + 2/3
y = (-1/3)x + 2/3 - 1
y = (-1/3)x - 1/3
Therefore, the equation of the perpendicular bisector of the segment with endpoints (1, -4) and (3, 2) is y = (-1/3)x - 1/3.

Answer:
x = 35°
y = 55°
Step-by-step explanation:
60° + 50° + 2x = 180° (Sum of angles on a straight line is 180°)
2x = 180° - 110°
x = 70°/2 = 35°
2x + 2y = 180°( Sum of interior angles of a triangle is 180°)
2× 35° + 2y = 180°
70° + 2y = 180°
2y = 180° - 70°
y = 110°/2
y = 55°
