Round 907.457 to the nearest tens place
Correct Answer
B. 910.00
Explanation
The given number, 907.457, needs to be rounded to the nearest tens place. The tens place is the digit immediately to the left of the decimal point. In this case, it is the digit 0. Since the digit to the right of the tens place is 7, which is greater than or equal to 5, we round up. Therefore, the number is rounded to the next highest ten, which is 910.00.

On Monday and Thursday, the cost of lunch is $5.43 total. On Tuesday and Wednesday the cost of lunch is $3.54 on each day. On Friday, the cost of lunch is $7.89. What was the average daily cost?
Correct Answer
D. 4.08
Explanation
The average daily cost can be calculated by adding up the total cost for each day and dividing it by the number of days. On Monday and Thursday, the total cost is $5.43. On Tuesday and Wednesday, the total cost is $3.54 + $3.54 = $7.08. On Friday, the cost is $7.89. Adding up all the costs, we get $5.43 + $7.08 + $7.89 = $20.40. Since there are 5 days in total, the average daily cost is $20.40 / 5 = $4.08.

A roast was cooked at 325Â° F in the oven for 4 hours. The internal temperature rose from 32Â° F to 145Â° F. What was the average rise in temperature per hour?
Correct Answer
B. 28.25
Explanation
The average rise in temperature per hour can be calculated by finding the difference in temperature and dividing it by the time taken. In this case, the difference in temperature is 145Â° F - 32Â° F = 113Â° F, and the time taken is 4 hours. Therefore, the average rise in temperature per hour is 113Â° F / 4 hours = 28.25.

There are 12 more apples than oranges in a basket of 36 apples and oranges. How many apples are in the basket?
Correct Answer
C. 24
Explanation
Since there are 12 more apples than oranges in the basket, we can set up an equation to represent this relationship. Let x be the number of oranges in the basket. Therefore, the number of apples would be x + 12. We know that the total number of fruits in the basket is 36. So, we can write the equation as x + (x + 12) = 36. Simplifying this equation gives us 2x + 12 = 36. By subtracting 12 from both sides, we get 2x = 24. Finally, dividing both sides by 2 gives us x = 12. Therefore, there are 12 oranges and 12 + 12 = 24 apples in the basket.

A train travels 20 feet in 1/5 seconds At this exact speed, how many feet will it travel in three seconds?
Correct Answer
D. 300
Explanation
The train travels 20 feet in 1/5 seconds. To find out how many feet it will travel in three seconds, we can set up a proportion. Since 1/5 seconds is to 20 feet, then 3 seconds is to x feet. Cross multiplying, we get (1/5) * x = 20 * 3. Simplifying, we get x = 300. Therefore, the train will travel 300 feet in three seconds.
