Question:
The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse. Which is an equivalent equation solved for y?
Answer:
[tex]y = \frac{a}{\pi x}[/tex]
Step-by-step explanation:
Given
[tex]a = \pi xy[/tex]
Required
Solve for y
The question implies that, we make y the subject of formula:
This is done as follows:
[tex]a = \pi xy[/tex]
Divide through by [tex]\pi x[/tex]
[tex]\frac{a}{\pi x} = \frac{\pi xy}{\pi x}[/tex]
Isolate y on the right hand side
[tex]\frac{a}{\pi x} = y[/tex]
Reorder
[tex]y = \frac{a}{\pi x}[/tex]
Hence, the solution to the question is: [tex]y = \frac{a}{\pi x}[/tex]

Find the equation of the line that is parallel to y = -7x + 2 and contains the point (-5,32)
Answer:
Y=-7x-3
Step-by-step explanation:
Answer:
y = - 7x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 7x + 2 ← is in slope- intercept form
with slope m = - 7
Parallel lines have equal slopes, thus
y = - 7x + c ← is the partial equation
To find c substitute (- 5, 32) into the partial equation
32 = 35 + c ⇒ c = 32 - 35 = - 3
y = - 7x - 3 ← equation of parallel line
The directions on a sewing pattern say to cut an extra 15% of fabric to account for error. Chloe needs 0.75 yardof fabric to make a skirt, and she cuts 0.1125 yard. Did Chloe cut the correct amount of fabric? Why or why not? A. 00:00 Chloe cut enough fabric because she cut the amount of fabric for the skirt. B. 00:00 Chloe cut enough fabric because she cut enough fabric for the skirt and the amount of extra fabric. C. 00:00 Chloe did not cut enough fabric because she only cut the amount of fabric for the skirt. D. 00:00 Chloe did not cut enough fabric because she only cut the amount of extra fabric.
Answer: D. Chloe did not cut enough fabric because she only cut the amount of extra fabric.
Step-by-step explanation:
From the question, we are informed that a direction on a sewing pattern say to cut an extra 15% of fabric to account for error and that Chloe needs 0.75 yard of fabric to make a skirt.
Based on the information given in the question, the extra fabric will be:
= 15% × 0.75
= 15/100 × 0.75
= 0.15 × 0.75
= 0.1125
Therefore, the correct amount of fabric to cut will then be the amount of yard needed for the skirt plus the extra. This will be:
= 0.75 + 0.1125
= 0.8625 yards
Based on the above calculation, Chloe did not cut the correct amount of fabric as she only cut the amount of extra fabric.

Consider the following table.
- Will the order pairs listed in the table form a straight line when plotted? Explain.
- Explain why the relationship represented in the table is non-proportional.
Answer:
No
Step-by-step explanation:
There is no pattern hence it will not form a straight line
There will be no straight line as there is no consistency in proportionality constant.
What is proportionality constant?The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality.
The relationship can be described as y = k x or y = k/x
As, from constant of proportionality
y = k x
k= y/x
k= 53/(-2)= -53/2 = -26.5
and, k= -22/1 = -22
and, k = -47/2 = -2.35
As, there no consistency in proportionality constant.
Hence, the table does not form straight line.

What’s the value of x
Answer:
16
Step-by-step explanation:
This is due to the rule that all shapes exterior angles add to 360.
Therefore 360 = 46 + 3x +62 + 4x + 47 + (180-83)
360 = 248 + 7x
7x = 112
x= 16

anna is x years old and her sister jane is y years old what will the sum of their ages be in 3 years
Answer:
S = x+y+9
Step-by-step explanation:
Age of Anna is x years and age of her sister is y years old.
3 years later,
Age of Anna = x+3
Age of her sister = y +3
Sum of their ages in 3 years will be :
S = x+3+y+3
S = x+y+9
Hence, this is the required solution.

Emily looks at a picture. A car in this picture is 30cm long. the scale of the drawing is 1:14
Answer:
Step-by-step explanation:
30 cm:
1: 14
so 1*14 = 14
so 30*14=420
so if you are trying to figure out how long it is in real life it's supposed to be 420 something.
The length of the car in real life is 420 cm or 4.2 meters.
What is Multiplication?Multiplication is a method of finding the product of two or more numbers
If the scale of the drawing is 1:14, this means that every 1 unit on the drawing represents 14 units in real life.
Since the car in the drawing is 30cm long, we can use this to figure out its length in real life units. Let's call the real life length of the car "x".
Using the scale, we can set up the following proportion:
1 / 14 = 30 / x
To solve for x, we can cross-multiply
x = 14 × 30
x = 420
Therefore, the length of the car in real life is 420 cm or 4.2 meters.

2. How many more minutes will it take for the tank drain completely? Explain or show your reasoning.
3. How many minutes before Jaila arrived was the water tank completely full? Explain or show your reasoning.
Answer:
Look below
Step-by-step explanation:
1)= -2/3 per minute decrease by 2 gallons in 3 minutes
2) 5 gallons and lose 2/3 gallons per minute
2/3 gal/minute minutes) = 5 gallons
x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons
3) 10 gallons when full
That is 3 gallons more than the 7 gals there when Jada arrived.
(2/3)(x) = 3
x = 3(3/2) = 9/2 = 4 1/2 minutes
Full= 4 1/2 minutes before she arrived
