V=1/3lwh
30.45=1/3×6.3×2.5×h
30.45=5.25h
h=5.8 ft, so the height is 5.8 feet. Hope it help!
For #32,
P=2L+2W
Subtract 2W from both sides, and swap left and right
2L = P-2W
Divide by 2
2L/2=(P-2W)/2
L = P/2 - 2W/2
L=P/2 - W
For #35
Most of the expenses are in fractions (of the original amount, A), so they can be added:
A/4 + A/5 + 2A/5 + 750 = A
add the fractions, with a common denominator of 20,
5A/20 + 4A/20 + 8A/20 +750 = A
(5A+4A+8A)/20 +750 = A
17A/20 + 750 = A
Now subtract 17A/20 from both sides and swap left and right
A - 17A/20 = 750
(3/20)A = 750
Multiply both sides by 20/3 (to make one unit of A on the left)
(3/20)*(20/3) A = 750*20/3
A =250*20=5000

Here, First term
common ratio
number of terms
If, and
Common ratio of the sequence
By substituting these values in the formula,
Therefore, Option E is the answer.
Answer:
Step-by-step explanation:
→ First look at the first term of each expression and see if they can be simplified, and they can
→ Now look at the a terms, since a larger one is at the top, you subtract
→ Now simplify the b and c terms
