first person who answer correctly gets a brainllest The perimeter of a rectangle is 64 feet. The length of the rectangle is 3 ti
anastassius [24]

Answer:

2(3(8))+2(8)=64

Step-by-step explanation:

Here, w represents the width of the rectangle,

∵ length of the rectangle is 3 times the width of the rectangle,

So, length = 3w,

Since, the perimeter of a rectangle, P = 2(length + width)

= 2(w + 3w)

= 2w + 2(3w)

If P = 64 feet,

⇒ 2w +2(3w) = 64

⇒ 2w + 6w = 64

⇒ 8w = 64

⇒ w = 8

Verification :

P = 2(8) + 2((3(8)) = 16 + 48 = 64 feet

Hence, the first step that should be taken to verify that the width of the rectangle is 8 is 2(3(8))+2(8)=64

Note : a solution obtain from an equation is verified by substituting the value in the equation.

A car is moving at a rate of 28 MPH, and the diameter of the wheel is about 2 1/3 feet. A) Find the number of revolutions per mi
cluponka [151]
1. Know that: (1) in 28 miles, there are 147,840 ft because 28*5280, (2) radius is 7/6 because that is (2 1/3)/2, (3) C=2(pi)(7/6) or pi*7:3 2. To find revolutions per minute, you take 147,840 and divide it by the circumference to get revolutions per hour, which is about 20168.11439. Then, divide this by 60 to find revolutions per minute: 336.1352398 revolutions/min. 3. Then, to find the angular measure in radians you take the revolutions per minute and multiply it by 2pi.
