Savannah bought barn wood for $60 for 5 pieces. She spent $40 on materials to paint
Kisachek [45]
Her profit per each wood is $5 so her total profit is $25

because
60 divided by 5 is 12, so each wood is 12 dollars
she spent 40 dollars on materials so 40 divided by 5 is 8, so she spent $20 on each piece of wood to paint it because 12(price of wood)+8(cost of materials per wood)= 20
and shes sells them for 25
so 25-20=5
5x5=25
so the answer is $25 profited

What's the equation for a circle with a center of (-2, 1) and a radius of 3.​
faltersainse [42]

Answer:

(x+2)^2 + (y-1)^2 = 9

Step-by-step explanation:

The equation of a circle is written with the center and radius into the vertex form (x-h)^2 + (y-k)^2 = r^2.

Here h = -2 and k = 1. Substitute these values with r = 3.

(x--2)^2 + (y-1)^2 = 3^2\\(x+2)^2 + (y-1)^2 = 9

A car is traveling at a speed of 55 mph. You want to write an algebraic expression to show how far the car will travel in a cert
WARRIOR [948]

distance = rate * time.

distance is number of miles the car has traveled.

rate = number of miles per hour the car is traveling at.

time = number of hours the car has been driven.

let D = distance.

let T = time.

let R = rate


the general equation is D = R*T

as long as the car will always be driven at 55 miles per hour, you can substitute 55 for R and that becomes your constant.

The equation then becomes D = 55 * T.

example:

you drive 5 hours.

D = 55 * T = 55 * 5 = 275 miles.

If you drive at 55 miles per hour for 5 hours, you will have driven 275 miles.

Hope this helps!
