Kimberly rides her bicycle from her home to school at an average rate of 12 mph if it takes her 20 minutes to get to school how
Thepotemich [5.8K]

Kimberly's home is 6.6 miles away from her school.

Step-by-step explanation:

The formula for speed will be used to calculate distance between home and school of Kimberly.

The formula for speed is:

s=\frac{d}{t}

Here

d is distance

s is speed and

t is time

Given:

Speed=s=12\ mph\\Time=t=20\ min\\\\We\ have\ to\ convert\ the\ time\ into\ hours\ for\ same\ unit\\t=20\ min = \frac{20}{60} = 0.33\ hour\\Now,\\20=\frac{d}{0.33}\\20*0.33=d\\d=6.6\ miles

Kimberly's home is 6.6 miles away from her school.

The lengths of the sides of a square are 5 cm. find the length of the diagonal
jenyasd209 [6]

Answer:

square root (50) = 7.071

Step-by-step explanation:

Using Pthagoras' theorem, the diagonal length is \sqrt{x} ax^{2} +bx^{2}.

Therefore, the diagonal length is the square root of 5^2+5^2,

= \sqrt{x} 25+25

= \sqrt{x} 50

= 7.071
