is continuous on [0, 3] and differentiable on (0, 3), so the mean value theorem applies here. It says that there is some

Answer:
$16
Step-by-step explanation:
To find the cost per square foot we have to solve the given equation for x:
6.4x - 3.7x = 43.2
2.7x = 43.2
Divide both sides of the equation by 2.7 to isolate the x:
2.7x/2.7 = 43.2/2.7
x = 16
The sheet metal costs $16 per square foot.
Hope this helps :)
Let the weights of the two candies be repres. by x and y.
Then x + y = 60, or x = 60 - y
($1.16 / lb) x + ($0.86 / lb) y = ($1.00 / lb) (60 lb) = $60
Then 1.16(60-y) + 0.86y = 60
69.6 - 1.16y + 0.86y = 60 9.6
9.6 = 0.3y Solving for y, y = ------- = 32 lb
0.3
Then x = (60-32) lb = 28 lb
Answer:
48 miles.
Step-by-step explanation:
A bus travels 36 miles in 45 minutes
In 60 minutes, travelling at this rate, the bus would cover:
× 36 miles = 48 miles
Answer:
