Answer:
volume of the square pyramid is:
V = s2h/3
where s=side length and h= height
for square pyramid A
h(a)= 8in and s(a)=12in
volume of square pyramid for A =
V(a)=s2(a) h(a)/3
V(a)=122 . 8/3 \implies⟹ 144 . 8/3 \implies⟹ 1152/3 \implies⟹ 384 in3
for square pyramid B
h(b)=24in and s(b)=36in
volume of square pyramid for B =
V(b)=s2(b) h(b)/3
V(b)=362 . 24/3 \implies⟹ 1296 . 24/3 \implies⟹ 31104/3 \implies⟹ 10368 in3
We want to know how many times the volume of pyramid B is bigger than pyramid A :
= V(b)/V(a)
=10368/384
= 27 times

hope this helps if not let me know have a great day
Answer:
Use reverse operations to find the original number.
15/2
7.5
The number that was originally thought of was 7.5.
:)
3.5,
since 3350/670 = 5, we know that the 2345.0/670 = 3.5
Answer:
13
Step-by-step explanation:
- x × (x + 9) = x² + 9x = 286
- x² + 9x - 286 = 0
- (x - 13)(x + 22)
- x = 13 or -22
- Since you cannot have negative length, it’s 13
3x + 5
Just combine like terms. The like terms are 2x and x. You can also write x as 1x. The sign is addition so you at 2x + 1x and get 3x. So now you have 3x + 5,you can’t add 3x + 5 cause they aren’t like terms so that’s your answer. :)
