For a triangular prism, the formula for volume is v=bh where b is the area of the base (72) and h is the height (20). 72x20=1440 so the volume is 1440 cm^3
As for surface area, you want to find the area of each of the faces. For the triangle faces the area is 72. For the three identical rectangle faces the area is 240. 240x3+72x2= 720+144=864cm^2
Hope this helped :)
The first answer would go into the 3rd slot, the second one goes into the fourth, the third one goes into the first slot, and the last one goes into the second slot
-19.35 + 15x
In order to get this answer distribute the 3 to the -6.45 and the 5x.
Answer:
Step-by-step explanation:
To convert the statement to decimals, we need to use the following conversion rate.
Since $1 = 100cents
Writing $6.00 to 95 cents as a decimal, we need to writw both units in the same units.
$6.00 to 95 cents = 600cents to 95 cents
= 600cents:95cents
= 600cents/95cents
= 6.32 (to 2dp)
For 3 hours to 35 minutes
SI=ince 1 hour = 60minutes
3 hours to 35 minutes = (3*60)minutes to 35 minutes
= 180minutes : 35 minutes
= 180minutes/35 minutes
= 5.14 (to 2dp)
For 42 inches to 2 feet
Given 12inches = 1 foot
42 inches to 2 feet = 42inches to (2*12)inches
= 42inches to (24)inches
= 42inches : 24 inches
= 42inches/24 inches
= 1.75 (to 2dp)
Answer:
x = 0, 4, -2
Step-by-step explanation:
f (x) = 3x (x – 4) (x + 2)
0= 3x (x – 4) (x + 2)
3x = 0, x-4 =0 , x+2 = 0
x = 0, 4, -2
