A because if you look t is on +3 and r is on -41/2
Answer:
3%
Step-by-step explanation:
105 = 700 x r x 5
r = 105 / ( 700 × 5 ) = 0.03
r = 0.03
0.03 in percent is 3%
Let the speed of the first train be v mph. Then the speed of the second train is:
(v + 50) mph.
Distance traveled by the first train from 3pm to 7pm = 4v miles.
The second train travels 4v miles in 2 hours (from 5pm to 7pm). Therefore the speed of the second train = (4v)/2 = 2v.
However the speed of the second train is also given by (v + 50) mph.
v + 50 = 2v
v = 50.
The speed of the first train is 50 mph and the speed of the second train is 100 mph.
Answer:
32 m^2
Step-by-step explanation:
First find the volume of the bottom section
V = l * w*h
V = 6 * 2 * 2 = 24 m^2
Then find the volume of the top section in green
The length is 6-4 =2, the height is 4-2, width is 2
V = = l*w*h = 2*2*2 = 8
Ad the volumes together
V = 24+8 = 32 m^2
Step-by-step explanation:
