For the volume of this solid, you’re first going to find the area of the front triangle. so base x height divided by 2. for this it would just be 4.5. then multiply that by the side length. so 4.5 x 3.5, which would be 15.75. so your answer would be 15.75 cubic centimeters
Answer:
A
Step-by-step explanation:
Hopefully this helps!
<u>Answer-</u> 0.05 lit of propane fuel will your friend need in order to boil 10 cups of water.
<u>Solution- </u>
The more efficient the stove is ,less the fuel you need to burn.
so efficiency and amount of fuel needed are inversely proportional with each other.
Given
Your stove is 25 percent = 0.25 efficient ,will boil 10 cups of water, using 0.1 lit of fuel .
0.25 × 2 = 0.5 =50 percent efficient stove ,will boil 10 cups of water, using 0.1/2 = 0.05 lit of fuel.
(∵ As multipling a factor of 2 with efficiency will make the amount of fuel needed half.)
15-4 = 11
11 x 2 = 22
22 + 2/3 = 68/3
W(4) = 3(4) + 7
w(4) = 12 + 7
w(4) = 19
