Volume of prismatic solid = area of base × height
Volume of a pyramid = 1/3 × area of base × height
here, A pyramid is given whose base is a square of side 7 inch and height is 8.5 inch.
Volume = 1/3 × 7^2 × 8.5 in^3
= 138.83 in^3
To the nearest whole number, volume = 139 in^3
The number of 30- period until the value if the give card be equal is 20 30- day period
<h3>How to write and solve equation</h3>
let
- Number of 30- day period = x
Card 1:
50 - 2x
Card 2:
40 - 1.50x
50 - 2x = 40 - 1.50x
50 - 40 = -1.50x + 2x
10 = 0.50x
- divide both sides by 0.50
x = 10/0.50
x = 20
In conclusion, it will take 20 30- day period until the value of the given card can be equal.
