I think I would first convert it to hours to solve it and then back to minutes at the end. Super strange it’s been asked for in minutes.
So to convert 20 minutes into hours, you need to multiply by 3.
This means you need to do the same to the other side, cause if they’ve travelled 2.5 miles in 20 minutes, they’d travel 3 times that in an hour.
So this is 7.5m/ph
But then they want it in minutes, so I suppose 7.5/60?
So 0.125m/pm?
The answer needs the volume of the original pyramid minus the small pyramid cut off.
Volume of pyramid = (area of base x height)/3
(12 x 6 x 14)/3 - (4 x 10 x 6)/3 = 256 m^3
The diagram is completely wrong so this problem is actually impossible to solve!
If you slice horizontally across a rectangular pyramid the ratios of the edges will remain constant.
The two rectangles are not the same shape! 12:6 is not the same ratio as 10:4
If the original pyramid in this question was sliced in half the top rectangle of the frustum would be 6 x 3.
In this diagram the height was reduced from 14m to 8m so the top 6m was removed.
If the base was 12 x 6 the top rectangle should be 6/14 smaller = 5.14m by 2.57m (not 10 x 4)
If you are brave you could point this out to your teacher
So, to figure out this problem you first need to solve for how much you have left after paying the base fee. Take the total ($84) and subtract by the base fee ($27). You will get 57 as your answer. Then, take $57 and divide it by $0.15 to get your answer. It is 380 minutes each month. The equation here is 84=27+0.15x.
Answer:
D
Step-by-step explanation:
eq. of given line is x+y=10
eq. of any line parallel to given line is x+y=a
if it passes through (-1,5) then -1+5=a
or a=4
reqd. eq of line is x+y=4
or y=-x+4
the answer is:
dotted line, shade below
