Answer:

a) 34mi

b) 10mi

c) 44mi

d) by Calculating the amount of miles it would take John to go to school plus the amount of miles it would take Sara to go to school. Then add the sum of the amount of miles it took for both to go to school.

Step-by-step explanation:

a) explanation:

$a^{2} +b^2=c^2$

$16^2+30^2=c^2$

$256 + 900 = c^2$

$c^2=1156$

$\sqrt{1156}=34mi$

b) explanation:

$a^{2} +b^2=c^2$

$6^2+8^2=c^2$

$36+64=c^2$

$c^2=100$

$\sqrt{100} =10mi$

c) explanation: we already have all the data from John's house to Sara's House.

John's House to Sara's House = John's House to School + Sara's House to School.

Sara's House to School (Question #1) = 34mi

John's House to School (Question #2) = 10mi

34(mi) + 10(mi) = 44(mi)

An item that was selling 72 is reduced to 60. Find the recent decrease in price. Round you answer to the nearest tenth.

Lubov Fominskaja [6]

You need to find what percentage the difference is of 72.

First, subtract 60 from 72:

72-60=8

Next, divide 8 by 72:

8/72=0.1111

To convert this decimal to a percentage, multiply it by 100:

100*0.1111=11.11

The percent decrease is 11.11%.

Hope this helps!!
