A certain field is a rectangle with a perimeter of 1030 feet. The length is 181 feet more than the width. Find the width and len
Bumek [7]

Step-by-step explanation:

the perimeter is

2×length + 2×width = 1030 ft

length + width = 515 ft

length = width + 181

now we use that in the first equation :

(width + 181) + width = 515

2×width + 181 = 515

2×width = 334

width = 167 ft

because of

length = width + 181

length = 167 + 181 = 348 ft

Company A had a loss of $255 in January. Company B had a profit of $162 in January. What was the difference between the profits
Julli [10]

Answer:

The difference of the profit of two companies is $ 417

Step-by-step explanation:

Given as :

The company A loss amount in January = $ 255

The company B profit amount in January = $ 162

Let the difference between there profits = x

So, x = company B profit - ( company A profit)

I.e x = company B profit - ( - company A loss)

Or, x = $ 255 + $162

∴   x = $ 417

Hence The difference of the profit of two companies is $ 417  . Answer

The radius of a car wheel is 14 inches. how many revolutions per minute is the wheel making when the car is traveling at 60 mph.
Dovator [93]

Answer:

721\ \frac{rev}{min}

Step-by-step explanation:

step 1

Find the circumference of the wheel

The circumference of a circle is equal to

C=2\pi r

we have

r=14\ in

substitute

C=2\pi(14)

C=28\pi\ in

assume

\pi=3.14

C=28(3.14)=87.92\ in

step 2

1\ mile=63,360\ inches

1\ hour=60\ minutes

we have that

The speed of the car is 60 miles/hour

Convert the speed to inches/minute

60\ \frac{mi}{h}=60(\frac{63,360}{60})=63,360\ \frac{in}{min}

step 3

Remember that

The circumference of the wheel subtends one revolution

so

1\ rev=87.92\ in

Convert the speed to rev/min

63,360\ \frac{in}{min}=\frac{63,360}{87.92}=721\ \frac{rev}{min}
