Andrea is laying straws end to end she has 8 long straws that are each 3/4 foot long. Has 5 short straws that are each 5/8 foot long . Long is the whole line of straws

The correct answer is 9.125 feet.

Step-by-step explanation:

Andrea is laying straws end to end to make a whole.

Length of long straws is foot and length of small straws is foot long.

Number of available long straws are 8 and small straws are 5.

Total length of the whole line is × 8 +  × 5 = 6 + 3.125 = 9.125 feet long.

Thus the total length of the the whole line Andrea made of straws is 9.125 feet long.

step-by-step explanation:

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
