Moon: 7.348 * 0^22 kg = 73480000000000000000000

Horse: 7.1 * 10^2 kg = 710

How horses would I need to balance the weight to make the horses equal in weight to the moon? Use scientific notation please.

To calculate how many horses would be needed to balance the weight of the moon, you can divide the weight of the moon by the weight of one horse:

73480000000000000000000 kg / 710 kg = 1.035 * 10^20 horses

Therefore, you would need approximately 1.035 * 10^20 horses to balance the weight of the moon.

School bus: 7.81 * 10^3 = 7810

Ant: 3 * 10^-6 = 0.000003

How ants would I need to balance the weight to make the ants equal in weight to the school bus? Use scientific notation please.

To calculate how many ants would be needed to balance the weight of the school bus, you can divide the weight of the school bus by the weight of one ant:

7810 kg / 0.000003 kg = 2603333333.33 ants

Therefore, you would need approximately 2.603 * 10^9 ants to balance the weight of the school bus.

Burj Khalifa: 4.54 * 10^8 kg = 454000000

Cell Phone: 1.5 * 10^-1 kg = 0.15

How phones would I need to balance the weight to make the phones equal in weight to the Burj Khalifa? Use scientific notation please.

To calculate how many cell phones would be needed to balance the weight of the Burj Khalifa, you can divide the weight of the Burj Khalifa by the weight of one cell phone:

454000000 kg / 0.15 kg = 3026666666.67 cell phones

Therefore, you would need approximately 3.027 * 10^9 cell phones to balance the weight of the Burj Khalifa.

Pyramid: 5.216 * 10^9 kg = 5216000000

Penny: 3.1 * 10^-3 kg = 0.0031

How pennies would I need to balance the weight to make the pennies equal in weight to the pyramid? Use scientific notation please.

No, it said that 1.681 * 10^9 was the wrong answer as was not correct. Need another answer for that problem please and thank you.

It says it is still wrong.

Apologies for the oversight. Let's try to solve it again:

Weight of the pyramid: 5.216 * 10^9 kg
Weight of one penny: 3.1 * 10^-3 kg

Number of pennies needed = Weight of pyramid / Weight of one penny
Number of pennies needed = 5.216 * 10^9 kg / 3.1 * 10^-3 kg
Number of pennies needed = (5.216 * 10^9) / (3.1 * 10^-3)
Number of pennies needed = (5.216 / 3.1) * 10^12
Number of pennies needed = 1.68 * 10^12

Therefore, you would need approximately 1.68 * 10^12 pennies to balance the weight of the pyramid.

To calculate how many pennies would be needed to balance the weight of the pyramid, you can divide the weight of the pyramid by the weight of one penny:

5216000000 kg / 0.0031 kg = 1681290322.58 pennies

Therefore, you would need approximately 1.681 * 10^9 pennies to balance the weight of the pyramid.
