B: 5.6 x 10 to the 12th power.
C: 1.5 x 10 to the 29th power.
D: 5.6 x 10 to the 29th power.
Answer:
B: 5.6 x 10 to the 12th power.
Step-by-step explanation:
8* 10^7 * 7* 10^4
Multiply the first terms and add the powers of 10
56 * 10 ^(7+4)
56. * 10 ^11
This is not proper scientific notation
We can only have one number in front of the decimal. We have to move the decimal one place to the left, which means we add one to the exponent
5.6 * 10^ (11+1)
5.6 * 10^12
Answer:
B: $1450
Step-by-step explanation:
(y + 2) = 3(x + 2)
(y − 8) = −3(x − 4)
(y + 8) = −3(x + 4)
To find a person's weight on earth when you know their weight on the moon, multiply the moon weight by 6 (since weight on the moon is 1/6 of weight on earth). Therefore, if a person weighs 16 pounds on the moon, they would weigh 96 pounds on earth.
The question asks how much a person weighs on earth if he weighs 16 pounds on the moon. The fact that a person weighs about 1/6 on the moon than on earth would indicate that weight on earth is larger. In this case, you can find the earth weight by multiplying the moon weight to 6 (since it is 1/6). So, using this formula, if a person weighs 16 pounds on the moon, he would weigh 16 * 6 = 96 pounds on earth.
To check if this is reasonable, if you have the earth weight, you can divide by 6 to see if you return to the original moon weight. In this case, 96 / 6 = 16, which is the given moon weight, so the answer seems reasonable.
