Answer:
20 miles in an hour.
Step-by-step explanation:
4/5=0.8
16/0.8=x/1
cross product
0.8*x=16*1
0.8x=16
x=16/0.8
x=20
Answer:
12
Step-by-step explanation:
x = k/y Multiply each side by y
k = xy Insert values
= 6 × 72
= 432
x = 432/y Let y = 36
= 432/36
x = 12
Recall that
d/dx sech(x) = - sech(x) tanh(x)
d/dx tan⁻¹(x) = 1/(1 + x²)
Then by the chain rule,
dy/dx = - sech(x) tanh(x) / (1 + x²)
A. 5 feet
To find the area of a rectangle, multiply length by width. Since the length is 15, you divide 75 by 15, so the width would be 5 feet.
3 5/8 as a decimal is 3.625
