Answer:
8.5 inches
Step-by-step explanation:
First let's find the time t when the depth of the snow is 7 inches.
To do this, we just need to use the value of D = 7 then find the value of t:
We want to find the depth of snow one hour from now, so we just need to use the value of t = 3 to calculate D:
The depth of snow one hour from now will be 8.5 inches.
Answer:
The PERIMETER P is the distance around the rectangle.
Let's call the width of the rectangle W and the length of the rectangle L.
As you go around the edge there two equal lengths and two equal widths.
The formula for the perimeter of a rectangle is P=2*L+2*W.
P=2L%2B2W
Substitute 290 for P and 62 for the width.
290=2L%2B2%2862%29
Solve for L.
290=2L%2B2%2862%29
290=2L%2B124
290-124=2L
2L=166
L=83
The equation L=83 means that the length is 83 cm.
CHECK your work.
2(62)+2(83) = 124+166 = 290cm.
The length of the rectangle is 83cm.
The answer is 0.1538461538 but you round it to the nearest tenth that gives you 0.2
Answer:
9+1/4g = h
Step-by-step explanation:
For a cube,
The volume is the cube of the side length.
To raise a product to an exponent, raise each factor to the exponent.
To raise a power to a power, multiply powers.
