Estimate 34,309 + 28,452 to the nearest ten thousand.
Correct Answer
60,000
60, 000
60000Explanation
To estimate 34,309 + 28,452 to the nearest ten thousand, we round both numbers to the nearest ten thousand before adding them. 34,309 rounds to 30,000 and 28,452 rounds to 30,000 as well. Adding these rounded numbers gives us 60,000, which is the estimated sum to the nearest ten thousand.Rate this question:

Mr. Peters car travels 25 miles on a gallon of gasoline. the gas tank holds 18 gallons. Which would result in an overestimate of the miles Mr. Peters can travel on a tank of gas?
- A.
20 * 18
- B.
30 * 20
- C.
25 * 18
- D.
20 * 20
Correct Answer
B. 30 * 20Explanation
Multiplying 30 by 20 would result in an overestimate of the miles Mr. Peters can travel on a tank of gas. This is because the car can only travel 25 miles on a gallon of gasoline, but multiplying by 30 assumes that the car can travel 30 miles on a gallon. Additionally, multiplying by 20 assumes that Mr. Peters has a gas tank that holds 20 gallons, which is also an overestimate since the tank actually holds 18 gallons.Rate this question:

Mr. Peters drove 312 miles in about 5 hours. What is the best underestimate of Mr. Peters rate of speed? Don't forget to mph for your units!!!!
Correct Answer
60 mph
60
60 miles per hour
62
62 mph
62mph
60mph
62 miles per hourExplanation
The best underestimate of Mr. Peters' rate of speed can be determined by dividing the total distance traveled (312 miles) by the maximum time taken (5 hours). This calculation gives us a rate of speed of 62 mph. However, since we are looking for the best underestimate, we round this down to the nearest whole number, which is 60 mph.Rate this question:

Which expression equals 7 to the 5th power?
- A.
7 x 5
- B.
5 x 5 x 5 x 5 x 5 x 5 x 5
- C.
7 x 7 x 7 x 7 x 7
- D.
7 x 5 x 7 x 5
Correct Answer
C. 7 x 7 x 7 x 7 x 7Explanation
The expression that equals 7 to the 5th power is 7 x 7 x 7 x 7 x 7. This is because when you raise a number to a power, you multiply the number by itself as many times as the power indicates. In this case, 7 is multiplied by itself 5 times, resulting in the answer.Rate this question:

Write 4 x 4 x 4 x 4 in exponential form. Remember that since you can write an exponent to say to the ____ power. Example 3 x 3 is 3 to the 2nd power
Correct Answer
four to the 4th power
4 to 4th power
4 to the 4th power
4 4th powerExplanation
The correct answer for this question is four to the 4th power, 4 to the 4th power, 4 to the 4th power, and 4 to the 4th power. This is because the question asks for the expression 4 x 4 x 4 x 4 to be written in exponential form. In exponential form, a number raised to a power is written as the base number followed by the exponent. Therefore, four to the 4th power, 4 to the 4th power, 4 to the 4th power, and 4 to the 4th power correctly represent the given expression.Rate this question:

Mr. Peters sends an email to 5 people and each of those people send an email to 5 more people. Which expression shows the number of people that will receive the email after the third round?
- A.
5 * 3
- B.
5 to the third power
- C.
3 to the 5th power
- D.
3 * 5
Correct Answer
B. 5 to the third powerExplanation
The expression "5 to the third power" represents the number of people that will receive the email after the third round. This is because in each round, each person sends the email to 5 more people. So, in the first round, 5 people receive the email. In the second round, each of those 5 people sends the email to 5 more people, resulting in 5 * 5 = 25 people receiving the email. In the third round, each of those 25 people sends the email to 5 more people, resulting in 5 * 5 * 5 = 125 people receiving the email.Rate this question:
