Answer:
uppercase B = StartFraction 3 uppercase V Over h
Step-by-step explanation:
The formula for the volume (V) of a pyramid is:
V = 1/3*B*h
where B is the are of the base and h is the height. We can isolate B, as follows:
multiply by 3 at both sides
V*3 = 1/3*B*h*3
divide by h at both sides
V*3/h = B*h/h
V*3/h = B
Answer: y=2x-3
Step-by-step explanation:
y-5=2(x-4)
y-5=2x-8
y=2x+5-8
y=2x-3
Step-by-step explanation:
it's simple:
- 8 tens + 19ones = 9 tens + 9 ones
- 8 tens + 2 ones =7 tens+12 ones
- 7 tens +25 ones = 9 tens + 5 ones
- 70+11=80+1
- 50+13=60+3
- 90+13=100+3
Answer:
5300.
If you're rounding to the nearest hundred you look at the tens place. If its 5 or over you go up. So in this case we'll raise the 2 to a 5 because 6 is above 5.
We are tasked to solve the value of p(8a) in the expression p(x)=3x^2-4.
This means that what would find the value of the expression when x=8a. To solve this, we simply substitute the value of x in the expression.
p(x)=3x^2-4
p(8a)=3(8a)^2-4
p(8a)=3(64a^2)-4
p(8a)=192a^2-4
