Volume is Length x width x height divided by 3. You have the length and the width. which equals 24. (6x4). The volume that is present is 72... the last thing you do in the equation is divide by three so multiply 72 by 3 and get 216. This is the LxWxH. Like I said before you have the L and the W, which is 24. You would divide 24 from 216. The Height is 9cm.
Let the length of the diameter be d and radius be r, thus to solve for d we proceed as follows:
r²+31²=(r+15)²
solving for d we solve for r
r²+961=r²+30r+225
putting like terms together we obtain:
r²-r²+961-225=30r
736=30r
solving for r
r=24.53
thus
d=24.5333×2
d=49.067~49.1
Answer is D. 49.1
Answer:
$52.80
Step-by-step explanation:
We have to find the rate of this problem.
If Lusia earned $33 for every 5 hours, then she earned $33/5 per hour. If we solve that, we get $6.60 dollars per hour. However, that's not what your question wants. It wants to figure out 8 hours. All we have to do is $6.6 * 8 because 8 is 8 times 1. We get $52.80.
Answer:
Step-by-step explanation:
1. Find the eighth term
You have an arithmetic sequence. It starts at 75 and each successive term is 5 more than the one preceding it
The general formula for the nth term (aₙ) is
aₙ = a₁ + (n - 1)d
where a₁ is the first term and d is the common difference (5) between consecutive terms. Thus,
a₈ = 75 + (8 - 1) × 5 = 75 + 7 × 5 = 75 + 35 = 110
2. Find the sum
The formula for sum of the first n terms of an arithmetic sequence is
So
