35. A piece of string 8m is cut into 10 shorter pieces. Each piece measures 3/4m expect for the last piece. What is the length of the last piece of string in cm?​

I'll setup up the problem and you can do the calculation

Step-by-step explanation:

Total length of string - L = 8m

Multiple pieces is - 0.75m

Number of multiple pieces that are 0.75m - n

Remaining (last) piece - R

what we need to solve

R = L - (0.75n)

first find n by dividing L by 0.75 taking only the whole number (throw away the fraction)

n = 8/0.75 (I'll leave that calculate to you)

Then substitute n in the equation above to get R

i think it is 18

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
