Answer: C) 0</h3>
================================================
Explanation:
If points F and E are the midpoints of segment VU and segment ST respectively, then segment FE is the midsegment of the trapezoid. The midsegment is parallel to the bases, and the midsegment's length is found by adding up the bases VS and UT, then dividing by 2.
(VS + UT)/2 = FE
(29 + x+17)/2 = 23 ... plug in given info; isolate x
(x+46)/2 = 23
x+46 = 23*2 ... multiply both sides by 2
x+46 = 46
x = 46-46 ... subtract 46 from both sides

x = 0</h3>
Answer:
x = 30
Step-by-step explanation:
- 2x + 10 + 4x = 70, that is
2x + 10 = 70 ( subtract 10 from both sides )
2x = 60 ( divide both sides by 2 )
x = 30
Answer:
79.4 %
Step-by-step explanation:
volume of cylinder : pi×r²×h
attention ! the question gives us the diameters, so for the radius, we need to cut them in half.
Va = pi × (10/2)² × 8 = pi×25×8 = 628.31853... ft³
Vb = pi × (12/2)² × 7 = pi×36×7 = 791.68135... ft³
100% Vb = 791.68135... ft³
1% Vb = 7.9168135... ft³
now, 628.31853... ft³ have been pumped into B.
so, how often does 1% of the volume of B fit into that filled volume ?
628.31853... / 7.9168135... = 79.36507937...% = 79.4%
