Answer:
D
Step-by-step explanation:
The line x originates from the center of the circle and forms a perpendicular line with line RS, which means that the line is bisected.
That means that line RT is half of line RS, or 7.
Then we can use the Pythagorean Theorem to find the measure of x.



b = √32
b ≈ 5.66
Answer:
Step-50*t + 30*m = 1500, (1) (pounds)
4*t + 3*m = 138. (2) (cubic feet)
From (2), express 3m = 138 - 4t, and substitute it into (1). You will get
50t + 10*(138-4t) = 1500, or
10t = 1500 - 1380 ---> 10t = 1120 ---> t = 112 TVs.
From this point, find the number of microwaves on your own.
