Volume of the prism is given by:
V=(base area)*(height)
thus:
base area=1/2(a+b)*h
=1/2(1.4+0.6)*2
=2 m²

Thus the volume will be:
V=2*1
V=2 m³

Volume after 30 min:
V=2×(0.8)
V=1.6 m³

Rate of emptying the tank is:
(2-1.6)/30=1/ 75 m³/min
time taken to empty the tank:
time=volume/rate
time=2/(1/75)
=150 min

Step-by-step explanation:

84,480 pennies

There are 84,480 pennies in a mile. Yes, that is correct – 84,480 pennies! An interesting fact to know: 16 pennies laid side by side constitute 12 inches in length, or one foot, and since 5,280 feet equals one mile, that gives us 84,480 pennies in a mile.

84,480x1264=106,782,720

Oduvanchick [21]

The angle RAT which is made with AR and AT line and shown in the figure of protector, measures 30 degrees.

<h3>How to measure the angle in protector?</h3>

Protector is the most useful device to measure the angle between two lines. To measure the angle between two lines using the protector following steps is followed:

Place the protector center point at the vertex of unknown angle.
One side of angle should be place at 0 mark line of this device.
Other side of angle will be equal to the angle shown in protector on that line.

In the given figure, The angle Between AR and AT line is 30 degrees shown in protector.

Thus, the angle RAT which is made with AR and AT line and shown in the figure of protector, measures 30 degrees.
