247 divided by 10^2 is 2.47 and 247 times 10^2 is 24,700
i think the answer is 8
bc the small one is 4 and the big one is 6
and the other one is 6 so it must be 8
Answer:
A = 1/2 B H area = 1/2 base X height
B = 2 A / H = 2 * 99 / 12 = 16.5 cm
dA / d t = 1/2 * (B dH / dt + H dB / dt)
dB / dt = (2 dA / dt - B dH / dt) / H
dB / dt = (2 * 1.5 cm^2 / min - 16.5 cm * 2 cm / min) / 12 cm
dB / dt = (3 - 33) / 12 cm/min = -2.5 cm/min
If you're using 7.6 percent, then you're not using 92.4 percent (100-7.6)
To find 92.4 percent of 67.8 billion do:
67,800,000,000*.924=<span>62,647,200,000 </span>
There are 4 significant figures as the zero is placed between significant numbers.
