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

-10 F is colder than -4 degrees?
Aleks04 [339]

Answer: yes, it is a smaller temperature, which means that is "colder"

Step-by-step explanation:

I guess that the question is:

Is -10°F colder than - 4°C?

Ok, when we have a temperature T in Celcius, the equation to transform this quantity to the Fahrenheit scale is:

T' = (T*9/5) + 32°

Replacing T by the temperature in celcius, we get:

T' = (-4°*9/5) + 32° = 24.8°F

This means that -4°C is equivalent to 24.8°F

And -10°F is a smaller value than 24.8°F (which mean that is colder)

This implies that -10°F is colder than -4°C

Then the statement is true.
