Answer:
117
Step-by-step explanation:
<DAB = <B + <C
Answer: D
Step-by-step explanation:
a^2 +b^2 = c^2
= 18
3\sqrt{2}^2= 18
18 + 18 = 36
The square root of 36 is 6
Well, I have never seen a question posed this way, but let's check it out by trial and error.
1^3 = 3
2^3 = 8
3^3 = 27 Hey! There's one. And the ones digit ends in 3.
Let's try another number that ends in 3 and see if it works as well.
13^3 = 2197 Wow. It works again. I never noticed this before, so you taught me something new.
I will test one more.
33^3 = 35937 Bingo. I think we have a winner.
Since they are similar, the dimensions are in the same ratio. L1 = 5, L2 = 15, so they are in a 3:1 ratio. So if V1 = 60, then W1×H1 = 60/5 = 12
W2 must also be 3×W1 and H2 3×H1, and
3×3 = 9. So take 12×9 (W×H1×9) ×15 (L2) = V2
V2 = 12×9×15 = 1620 cm^3
Let me know the right answer when you find out!
