Simplify negative 15.5 divided by 5. and pls tell me how to simplify and give a step by step explanation thanks!

geniusboy [140]

Answer:

The answer is -3.1, or 3 1/10.Since diving a negative and a positive equals a negative, your quotient will be negative. You can start by removing the 0.5, and divide 15 by 5 which is 3. Then with the 0.5 from -15.5, divide it by 5 and you get 0.1. 3 plus 0.1 is 3.1, and since it has to be negative, it's -3.1.

i tried, have a nice day (:

Which of the following sets of numbers could represent the three sides of a right triangle?

svetoff [14.1K]

Answer:

{39, 52, 65}

Step-by-step explanation:

<u><em>The complete question is</em></u>

Which of the following sets of numbers could represent the three sides of a right triangle?

{44, 60, 75}

{30, 73, 78}

{37, 77,85}

{39, 52, 65}

we know that

The three sides of a right triangle must satisfy the Pythagorean Theorem

so

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

where

c is the greater side (the hypotenuse)

a and b are the legs (perpendicular sides)

<u><em>Verify each case</em></u>

case 1) we have

{44, 60, 75}

Let

$c=75\ units\\a=44\ units\\b=60\ units$

substitute

$75^2=44^2+60^2$

$5,625=5,536$ ----> is not true

so

The set of number could not represent the three sides of a right triangle

case 2) we have

{30, 73, 78}

Let

$c=78\ units\\a=30\ units\\b=73\ units$

substitute

$78^2=30^2+73^2$

$6,084=6,229$ ----> is not true

so

The set of number could not represent the three sides of a right triangle

case 3) we have

{37, 77,85}

Let

$c=85\ units\\a=37\ units\\b=77\ units$

substitute

$85^2=37^2+77^2$

$7,225=7,298$ ----> is not true

so

The set of number could not represent the three sides of a right triangle

case 4) we have

{39, 52, 65}

Let

$c=65\ units\\a=39\ units\\b=52\ units$

substitute

$65^2=39^2+52^2$

$4,225=4,225$ ----> is true

so

The set of number could represent the three sides of a right triangle
