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]

which two integers is square root 102 between? please help
Answer:
-50 and -52
Step-by-step explanation:
An even number can be generally expressed by 2n. So the sum of an even and its consecutive it's expressed by 2n+2n+2 this must be equal to -102. So we have to solve the nearly trivial equation 4n+2=−102 that solved gives n=−26. This means that the two numbers are
2⋅(−26)=−52 and 2⋅(−26)+2=−50
Right answer please

(12-15) Q(x) = 2x^4 - 7x^3 + 6x^2 + x -2
1. Use synthetic division to determine whether (x-1) is a factor of Q(x).
2. Use synthetic division in to find Q(-2)
3. List all of the possible rational roots of Q(x) = 0
4. Find all of the real roots Q(x) =0
Answer:
1) [tex]Q(x)=2x^{4}-7x^{3}+6x^{2} +x-2\\\\=(x-1)^{2}(x-2)(2x+1)\\[/tex]
2) Q(-2) = (-2-1)².(-2-2).(2.-2+1)
= (-3)².(-4).(-3)
= 108
3) Q(x) = 0
=> (x-1)²(x-2)(2x+1) = 0
⇔ x - 1 = 0 or x - 2 = 0 or 2x +1 = 0
4) x-1 = 0 or x - 2 = 0 or 2x + 1 = 0
⇔ x = 1 or x = 2 or x = -1/2

Suppose s varies directly with t. When t27, s=3. What is s when t=632
Answer
567
G
7
H
Answer:
G 7
Step-by-step explanation:
If t= 27 when s=3 27/3=9
the t=63 when s= 7 63/7= 9
Answer:
G
Step-by-step explanation:
Given that s varies directly with t then the equation relating them is
s = kt ← k is the constant of variation
To find k use the condition when t = 27, s = 3 , then
3 = 27k ( divide both sides by 27 )
[tex]\frac{3}{27}[/tex] = k, that is
k = [tex]\frac{1}{9}[/tex]
s = [tex]\frac{1}{9}[/tex] t ← equation of variation
When t = 63, then
s = [tex]\frac{1}{9}[/tex] × 63 = 7 → G
in a bean bag toss game players earn 2 points for each beanbag that lands on the game board and 5 points for each bean bag that lands in the hole. roopesh wants to know his total score after throwing 4 bean bags.
which expressions show the points roopesh earns if two beanbags land on the board? choose all that apply
2+5
2•2
2•5
2+2
Answer:2•2 and 2+2
Step-by-step explanation:
Because if you have 2 bean bags and 2 point for each bean bad it u have to multiply of add
The expression will be either (2+2) or (2*2).
What are expression?An algebraic expression consists of unknown variables, numbers and arithmetic operators.
Given that, in a bean bag toss game, players earn 2 points for each beanbag that lands on the game board and 5 points for each bean bag that lands in the hole.
Roopesh's dropped the bag on land for two times, and points for bag landing is 2, therefore, his score will be 2*2 or 2+2
Hence, The expression will be either (2+2) or (2*2).

Karina is making accessories for the soccer team. She uses 541.37 inches of fabric on headbands for 40 players and 3 coaches. She also uses 387.20 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer: 22.27 inches.
Step-by-step explanation:
Given : Karina uses 541.37 inches of fabric on headbands for 40 players and 3 coaches.
i.e. 541.37 inches of fabric on headbands used for 43 persons .
Fabric used per person for headband = [tex]\dfrac{541.37}{43}=12.59\text{ inches}[/tex]
She also uses 387.20 inches of fabric on wristbands for only players.
Fabric used per person for wrist band = [tex]\dfrac{387.20}{40}=9.68\text{ inches}[/tex]
Total fabric used for each player = 12.59+9.68 = 22.27 inches.
Hence, 22.27 inches. of fabric was used on a headband and wristband for each player.

A one-gallon can of paint costs $9.92. A five-gallon can of paint costs $43.29. How much will someone save if they buy the five-gallon can rather than five one-gallon cans?
Answer:
You save $6.31.
Step-by-step explanation:
For this we need to find the unit price. To do that we take the cost/unit(in this case gallon
For the one gallon can we'll do 9.92/1 =9.92.
The unit price for the one gallon is $9.92 per gallon.
For the 5 gallon we'll do 43.29/5 = 8.66
The unit price for the five gallon is $8.66.
So we'll subtract 5•(9.92)-5•(8.66) =49.6-43.29= $6.31.
You save $6.31.
