Answer:

50000000000

Step-by-step explanation:

For (5×10^– 2): 10 to the negative second power equals -100. 5 x -100 = -500.

For (1×10^– 8): 10 to the negative eighth power equals -100000000. Multiplied by one is obviously the same exact number. So -500 x -100000000 = 5000000000. Remember that negative numbers multiplied by negative numbers will always equal positive numbers. And positive numbers multiplied by negative numbers will always equal negative numbers.

The mass of a freight train is 9.98 ⋅ 106 kilograms. The mass of an aircraft carrier is 7.3 ⋅ 107 kilograms. Approximately how many more kilograms is the mass of an aircraft carrier than the mass of a freight train? Show your work and write your answer in scientific notation? Please help will give brainliest and high points.

Answers

Answer: 6.302 ⋅ 10^7 kg

Step-by-step explanation:

Subtract the mass of freight train from the mass of the aircraft carrier:

(7.3 ⋅ 10^7) - (9.98 ⋅ 10^6)

Get both to have the same exponent (6) by moving the decimal on 73:

(73 ⋅ 10^6) - (9.98 ⋅ 10^6)

Subtract the leading numbers:

(73-9.98) ⋅ 10^6 = 63.02 ⋅ 10^6

Move the decimal back so the answer is in scientific notation:

6.302 ⋅ 10^7 kg

In a school election, 3/4 of the students vote. There are 1464 ballots. Write and solve an equation to find the number s of students.

An equation is ??? =1464.

There are a total of ???
students.

Answers

The equation used could be dividing your number of ballots (number of students that voted) by three to get one fourth of the students. Then you could multiply that number by four to get four fourths, or all of the students. The answer would be 1952. In other words, your equation is 3/4 * x = 1464, then to get 1952, solve for x. Hope this helps!

The total number of students will be 1952.

Based on the information, let the total number of students be x.

Therefore, the equation to solve the question will be:

3/4x = 1464

0.75x = 1464

x = 1464/0.75

x = 1952

In conclusion, the correct option is 1952.
