Answer:
7.6 in
Step-by-step explanation:
c = 2πr Divide each side by 2π
r = C/2π Insert values
r = 48/(2×3.14)
r = 48/6.28
r = 7.6 in
Let x = number of months.
Let y = total number of fish in pond.
6% of 3,000 = 180 fish
We can use an equation to help us with this problem.
y = 3,000 + 180x - 400x. Combine like terms.
y = 3,000 - 220x. Plug 9 in for x.
y = 3,000 - 220(9). Solve for y
y = 1,020.
There are 1,020 fish in the pond after 9 months.
Answer:
y = 4x + 16
Step-by-step explanation:
y - 1 = 4(x + 3)
Has a slope of 4
y = 4x + c
32 = 4(4) + c
32 - 16 = c
c = 16
y = 4x + 16
PEMDAS means we do exponents before we multiply.
10 ^ 7 = 10,000,000
(10 * 10 * 10 * 10 * 10 * 10 * 10)
5.8 * 10,000,000
= 58,000,000
