Answer:
2.3 by 10^7
Step-by-step explanation:
We want this rewritten in the form 2.3*10^n.
To get the decimal point in 23,000,000 between the 2 and 3, we must move it 7 places to the left, and then compensate for this by multiplying 2.3 by 10^7.
3 1/4 = 3.25
1 mile = 5280

Correct answer is D. 17,160
Answer:
243cm^3
Step-by-step explanation:
By Pythagoras' Theorem,
height of the prism ^2 + 5.4^2 = 7.8^2
height of the prism = ±√(7.8^2 -5.4^2) = ±5.6285cm (5s.f.) (rej. - 5.6285 since height > 0cm)
volume of the prism = 1/2 x 5.4 x 5.6285 x 16 = 243cm^3 (3s.f.)
