Answer:48.6
we know that
You can paint 75 square feet of a surface every 45 minutes
so
using proportion
Find out how long it takes you to paint a surface area of 81 square feet
45(81)/75=48.6
hope this helped and I hope you get a correct answer :D
The formula of compound continuously is
A=p e^rt
A future value?
P present value 300
R interest rate 0.07
T 4 years
E constant
A=300×e^(0.07×4)
A=396.94 round your answer to get
A=397
Answer:
x= 0.78 (rounded to the hundredth)
Step-by-step explanation:
-5.5x + 0.46 = -3.94
You need to isolate x so the easiest thing to do is subtract 0.46 and move it to the other side of the equal sign.
-5.5x= -3.84 - 0.46
-5.5x = -4.3
divide -5.5 to get x alone
x= -4.3/-5.5
x= 0.78
10-11= -1 You could also input this number on a calculator
