85/100 is greater

85/100=.85 or 85%

21/25=.84 or 84%

.85 is greater than .84 so 85/100 > 21/25

You have to multiply 21/25 so that both denominators are the same.
so you get 84/100 therefor 85/100 is bigger

The length of a rectangle is 7 1/2 inches and the width is 4 3/4 inches. What is the ratio, using whole numbers, of the length t

Mariana [72]

Ratio is a division in its simplest form.
To get the ratio of length to width, divide the two then simplify.

In this case, convert the length and width into decimals.

length = 7 1/2 = 7.5
width 4 3/4 = 4.75

ratio of length to width is;
7.5/4.75 = 750/475

This can now be written as;
750 : 475
Dividing both sides by 25;

= 750/25: 475/25

= 30 : 19

The length of a rectangle is 12 in. and the perimeter is 56 in. find the width of the rectangle

pentagon [3]

The perimeter p of the rectangle with length l and width w is:
p = 2l + 2w
that is, two times its length and two times its width, lets solve for the width w and substitute known data:
p = 2l + 2w
2w = p - 2l
w = (p - 2l)/2
w = (56 - (2*12))/2
w = (56 - 24)/2
w = 32/2
w = 16
therefore the width of the rectangle is 16 in

You need to rent a truck for one day to move equipment. FAST Movers will rent the truck for $39.95 per day with unlimited mileag

Gekata [30.6K]

Hi there! :)

Answer:

Cost with FAST Movers: $39.95

Cost with SPEEDY Movers: $38.70

⇒ SO, it would be cheaper to go with the SPEEDY Movers.

Step-by-step explanation:

Since the FAST Movers ask for 1 price only and don't charge for mileage, the cost with the FAST Movers would be $39.95.

For the SPEEDY Movers, they ask for a flat rate of $29.95 and charge $0.35 per mile for all miles over 75 miles.

Since you traveled 100 miles, they would charge you for the extra 25 miles (100 - 75 = 25).

They charge $0.35 for 1 mile, so in order to know how much they charge for 25 miles, you'll need to multiply "0.35" by "25" :

0.35 × 25 = $8.75

So for the SPEEDY Movers, you would be charged $29.95 plus $8.75 for the extra miles:

29.95 + 8.75 = $38.70 ⇒ The cost with the SPEEDY Movers

There you go! I really hope this helped, if there's anything just let me know! :)
