A city’s record high temperature is 106°F and record low temperature is −17°F. How much warmer is the city’s record high temperature than the record low temperature? (1 point)
A. 123F
B. -123F
C. 89F
D. -89F
To find the difference between the high and low temperatures, we subtract the low temperature from the high temperature: 106°F - (-17°F) = 106°F + 17°F = 123°F.
Therefore, the city's record high temperature is 123°F warmer than the record low temperature.
The correct answer is A. 123°F.
You have a score of −500 points in a game. After three rounds of answering your questions correctly, you have a score of 2,700 points. What is the change in score?
A. 2,200 points
B.3,200 points
C.1,700 points
D.2,700 points
To find the change in score, we subtract the initial score from the final score: 2,700 points - (-500 points) = 2,700 points + 500 points = 3,200 points.
Therefore, the change in score is 3,200 points.
The correct answer is B. 3,200 points.
A diver is 15 feet below sea level. The diver then swims up 15 feet to the surface. Which expression shows the correct sum?
A. (−15)+(−15)=0
B.(−15)+15=30
C.(−15)+15=0
D.(−15)+(−15)= -30
The correct expression to represent the sum is (−15) + 15 = 0.
In this case, the diver starts at a depth of -15 feet below sea level and swims up 15 feet. The negative sign in front of the 15 indicates that the diver is moving in the positive direction (up) from a negative starting point. Adding -15 and +15 together cancels out the negative and positive values, resulting in 0.
Therefore, the correct answer is C. (−15) + 15 = 0.
To find out how much warmer the record high temperature is than the record low temperature, you need to calculate the difference between the two temperatures.
The record high temperature is 106°F, and the record low temperature is -17°F.
To find the difference, subtract the record low temperature from the record high temperature:
106°F - (-17°F)
Simplifying the expression, we get:
106°F + 17°F
Which equals:
123°F
Therefore, the city’s record high temperature is 123°F warmer than the record low temperature.
So the correct answer is:
A. 123°F.
To find out how much warmer the record high temperature is than the record low temperature, we need to subtract the record low temperature from the record high temperature.
Given that the record high temperature is 106°F and the record low temperature is -17°F, we can calculate the difference as follows:
106°F - (-17°F)
To subtract a negative number, we can change it to a positive number by adding it to the positive number:
106°F + 17°F
This gives us:
123°F
Therefore, the record high temperature is 123°F warmer than the record low temperature.
So, the answer is A. 123F.
