Answer:
4.5 is the answer 9/2=4.5
Step-by-step explanation:
Q=2*s*L(T2-T1)/ (R2/R1)
1500000=2*30*10(275-22)/(R2/6)
1500000=600(253)/(R2/6)
1500000R2=600*253*6
1500000R2=910800
R2=910800/1500000
R2=0.6072.
Answer:
OB
Step-by-step explanation:
The slopes are not changed.
See the picture of the 2 graphs. The slopes are the same,, but the y intercepts are different, so the lines are parallel.
The figure can be splitted into 2 trapeziums.
Hence, 14.5 * 16 + 20 * 10 = 432.
