Miguel has $250 dollars saved and he adds $5 to his savings every week. which
function describe the amount a, in dollars, that miguel has saved after t weeks?
a. a(t) = 5t + 250
b. a(t) = -5t + 250
c. a(t) = 250t +5
d. a(t) = 5t - 250

two data sets with the same median will not have the same varaibility

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
