Which expression is equivalent to 3 7/8 - 6 1/4 Choose 1
3 7/8 + (6 1/4)
-6 1/4 + (-3 7/8)
6 1/4 - (3 7/8)
3 7/8 + (-6 1/4)

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

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

current in the circuit at time t is /, then the power delivered to the resistor is
