A convertible is traveling at 45 miles per hour, and its wheels have a diameter of 48 inches. How many complete revolutions do t

neonofarm [45]

To answer this question you will need to know how many inches the car travels Per minute.

1. To find this out you will first divide 45 miles by 60 to get the number of miles per minute.

The convertible travels 0.75 mi./min.

2. Next you will convert this number of miles to inches.

There are 63,360 inches per mile.

0.75 x 63360 = 47520 inches per minute.

3. You then need to find the distance the wheel travels in one rotation. You will need to find the circumference of the wheel.

C = pi x d
3.14 x 48
C = 150.72 inches
Each rotation is about 150.72 inches.

4. Finally, divide the total distance traveled in a minute by the circumference(distance of one rotation) to get the total number of rotations in a minute.

47520/150.72 is about 315.3 rotations per minute.

Can someone help me with this? Right answer gets brainliest!! :)

I have 2 answers in mind

Answer #1:

$\frac{y}{z}$

Step-by-step explanation:

quotient means the answer to 2 things being divided so the quotient of y and z would be $\frac{y}{z}$ because there is no numerical value.

Answer #2:

Step-by-step explanation:

Usually, when a letter is left by itself in an equation it usually has an invisible one in front of it. so when dividing y by z it would equal 1/1 which is equal to one.

Hope this helps :)

Let's move like a crab, backwards some.

after 2 years?

is that enough to pay the $1100?

now, let's write 1000(1+r)² in standard form

1000( 1² + 2r + r²)

1000(1 + 2r + r²)

1000 + 2000r + 1000r²

1000r² + 2000r + 1000 <---- standard form.

Area of the square bottom = L x W = 5 x 5 = 25 square cm

Area of triangle = 1/2 x base x height = 1/2 x 5 x 6 = 15 square cm

Total area = 25 + 15 = 40 square cm.
