Answer:

11.

Step-by-step explanation:

I got the answer of 11, as I:

-First, I worked out how many rides Margaret would be able to go on, so I did $35 -/- $3, which was a decimal, but the most amount of times would be 11 rides that she could go on, therefore, that's the amount of rides she would take, and have $2 left over.

fredd [130]

Answer:

The dimension of the rectangular pool is 112.5\times 37.5

Step-by-step explanation:

Given : A rectangular swimming pool is three times as long as it is wide. If the perimeter of the soccer field is 300 yards.

To find : What are the dimensions?

Solution :

Let the width of the rectangular pool be 'x'.

A rectangular swimming pool is three times as long as it is wide.

The length of the pool be '3x'

The perimeter of the rectangular swimming pool is P=2(l+w)

The perimeter of the soccer field is 300 yards.

Substitute the value in the formula,

300=2(3x+x)

300=2\times 4x

300=8x

x=\frac{300}{8}

x=37.5

The width of the pool is x=37.5 unit

The length of the pool is 3x=3(37.5)=112.5

Therefore, The dimension of the rectangular pool is 112.5\times 37.5

2h divided by 15 equals 20
Lynna [10]
<span>(2*h)/15 = 20 // - 20

(2*h)/15-20 = 0

2/15*h-20 = 0 // + 20

2/15*h = 20 // : 2/15

h = 20/2/15

h = 150

h = 150</span>

A fish swims at a speed of 12 miles per hour. A boy swims at a speed of 4.4 feet per second. 3 ft = 1 yd 5280 ft = 1 mi How much
just olya [345]
You'll need to convert both speeds into yards per minute.

12 mph = 12 mph     1760 yd    60 min
                ---------- * ------------ * ----------
                  1 mile       1 hr

Note that "miles" cancels.  So does "hours."  Finish this work.

Then convert   4.4 ft/sec into yards per minute.

Then, finally, compare your two rates via subtraction of the smaller from the larger.
