70 miles in 3 hours = 70/3 ≈ 23.33 mph
If 1 mile = 1609 m the 23.33 miles≈ 37543.33 meter per hour.
Divide by 60 to change to meters per minute and again by 60 to change meters per minute to meters per second - Shortcut is to divide by 60 x 60 or 3600
<u>37543.33 </u>≈ 10.428 meters per second. Answer a. is correct<u>
</u>3600

there are two expressions that can represent the length of the rectangle, these two expressions are:
L = x
or
L = (4x + 12)
<h3>
Which expression could represent the length of the rectangle?</h3>
Remember that for a rectangle of length L and width W, the area is given by:
A = L*W
In this case, we know that the area is:
We can factorize that expression into:
So there are two expressions that can represent the length of the rectangle, these two expressions are:
L = x
or
L = (4x + 12)

Answer:
d=10.0002
Step-by-step explanation:
Given That:
Height=h=28 inches
Volume=V=732.7 cubic inches
Required:
Diameter of the base of the cone=d=?
Solution:
the formula for the volume of a cone is
re-arranging the terms to get the radius (r)
putting values, we get
to find the diameter we know that diameter is double of the radius so
d=2r
d-2(2.0051)
d=10.0002
Let the width be x.
Length = 4x
Area = 100 sq. feet
lw = 100
4x * x = 100
4x² = 100
(2x)² = (10)²
2x = 10
x = 5
Therefore,
Length = 4 * 5 = 20 ft
Width = 5 ft
Hence,
Perimeter = 2(l + w) = 2(20 + 5) = 2 * 25 = 50 ft
Hence, the perimeter is 50 ft.
