a photographer wants to enlarge a 5x7 photo for a wall mural without distorting its width-to- length ratio. What are the largest
krok68 [10]

The largest dimension of the enlarged photo will be: Width= 175 inches and Length= 245 inches.

<u><em>Explanation</em></u>

Dimension of the original photo is 5×7 . That means the ratio of the width to the length is 5 : 7

So, lets assume the width is 5x and length is 7x for the enlarged photo.

Formula for the perimeter of a rectangle =2(length+width)

As the perimeter of the enlarged photo should not exceed 840 inches, so...

2(7x+5x)\leq 840\\ \\ 2(12x)\leq 840\\ \\ 24x\leq 840\\ \\ x\leq \frac{840}{24}\\ \\ x\leq 35

That means the maximum value of x must be 35.

So, the largest possible width =5x=5*35=175 inches

and the largest possible length = 7x= 7*35=245 inches

Part A: Rhett made $250 washing cars with his mobile car wash company. He charges $70 per car and earned $50 in tips. Write an e
Alborosie

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Total Amount made = $250

Amount charged = $70 per car

Tips earned = $50

Equation 1 to represent the above

(Amount charged per car × number of cars) + tips earned = total amount made

Let number of cars = c

Hence,

$70c + $50 = $250

Part B:

Total Amount made = $250

Amount charged = $75 per car

Tips earned = $35

Cost of supplies per car washed = $5

Equation 2:

(Amount charged per car × number of cars) + tips earned - (cost of supplies × number of cars) = total amount made

$75c + $35 - $5c = $250

$70c + $35 = $250

C) Equation 1 does not include the cost incurred in getting the car washed while equation 2 takes into account the cost incurred in washing a car which is then subtracted from the amount charged per car. Also the tips earned in equation 1 is $50 while equation has a tips fee of $35
