Let the width of the rectangle be 'w'

According to the question length of the rectangle (l) is three feet more than twice it's width;

\longrightarrow l = (2w + 3) ft

Perimeter of rectangle = 78 ft

Formula of perimeter of rectangle = 2(Length + Width)

So,

\rm \implies 2(Length + Width) = 78 \\  \\  \rm \implies 2(2w + 3 + w) = 78 \\  \\  \rm \implies 2(3w + 3) = 78 \\  \\  \rm \implies 2 \times 3(w + 1) = 78 \\  \\  \rm \implies 6(w + 1) = 78 \\  \\  \rm \implies w + 1 =  \dfrac{78}{6}  \\  \\  \rm \implies w + 1 = 13 \\  \\  \rm \implies w = 13 - 1 \\  \\  \rm \implies w = 12 \: ft

\therefore Width of the rectangle (w) = 12 ft

Two mechanics worked on a car. The first mechanic worked for 5
ArbitrLikvidat [17]

<u>Answer:</u>

$50 and $115

<u>Step-by-step explanation:</u>

We know that,

the sum of the two rates = $165 per hour

Let x and (165 - x) represent the $/hour of the 15hr and 5hr mechanics respectively.

Then combining their charges together to get:

(x*15)hour+(165-x)*5 hour=1325

Solving for x to get:

15x-5x+825=1325

10x=500

x=50

So the rate charged per hour by one mechanic is $50 and for the other mechanic = (165-50)= $115.

A quadratic equation is in the form:

y = ax² + bx + c

it costs the zoo 0.86 per day to feed each bat a variety of soft fruits. Hence:

Cost of 17 egyptian fruit bats = $0.86 per day * 17 = $14.62

It costs the zoo 0.86 per day to feed each bat a variety of soft fruits, therefore the cost of 17 egyptian fruit bats would be $14.62
