E. 1/5÷3=
Please explain your answers

Step-by-step explanation:

Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,

Addition and subtraction requires that we find a common demoninator.

For example,

The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.

Then we add the numerators

Then we should reduce.

Division is a little trickier because we have to flip-flop the second term and then multiply. For example:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer: c
