Answer:
38.4895
Step-by-step explanation:
area of circle = pi * r^2
3.142 * 7^2 = area of the whole circle
as we only have 1/4 of the circle we divide our area by 4
(3.142 *7^2) / 4 = 38.4895
Answer:
38.4895
Step-by-step explanation:
basically you are finding a quarter of the area of the circle. So the formula is 1/4πr^2
so that's 3.142×7^2 and then divided by 4.
hope this helps

Answer:
120 cars
Step-by-step explanation:
The given function is
[tex]C(x)=0.5x^2-120x+21,481[/tex]
and its parent function would be
[tex]f(x)=ax^2+bx+c[/tex]
So,
[tex]a=0.5[/tex]
[tex]b = -120[/tex]
and
[tex]c = 21,481[/tex]
The minimum cost would be found using:
[tex]x = -\frac{b}{2a}[/tex]
So just input a and b into the function:
[tex]x= -\frac{-120}{2(0.5)}[/tex]
[tex]x=-\frac{-120}{1}[/tex]
[tex]x = 120[/tex]
Therefore there must be 120 cars made to minimize the cost.

How many solutions does the equation 3x 6 = − 1 − 3 4x have? two zero one infinitely many

The nature of solutions to equations can be finite, infinite or no solution. The solution to the system of equation 3x + 6 = -1-3 + 4x is 10
Solution to system of equationsThe nature of solutions to equations can be finite, infinite or no solution.
Given the linear solution as shown:
3x + 6 = -1-3 + 4x
Collect the like terms
3x - 4x = -1 -3 -6
-x = -10
Multiply both sides by -1
-(-x) = -(-10)
x = 10
Hence the solution to the system of equation 3x + 6 = -1-3 + 4x is 10

Gina can buy oranges individually.
How much will Gina save if she buys 24 oranges at Store B?
Show your work.
Answers
Answer:
She saves 24 cents by buying 24 oranges at store B
Step-by-step explanation:
Price per orange A = 6.48 / 12 oranges = .54 per orange
.54 * 24 oranges = 12.96 for store A
Price per orange B = 2.65 / 5 = .53 per orange
.53 * 24 oranges = 12.72 for store B
12.96 - 12.72 = .24 dollars (24 cents)
