Abraham needs one-half of a point to get an A– in Math. What rational number can be used to represent the number of points needed for Abraham to get an A–?
Give me a good answer of it or just tell it all
also 2-4 answers are wrong
The rational number that can represent the number of points needed for Abraham to get an A– in Math is 0.5.
In the grading system, an A– typically represents a numerical grade between 90 and 93, depending on the scale used by the educational institution. Assuming that the maximum grade is 100, Abraham must score at least 90.5 to achieve this A– grade. Since a point is the smallest unit of measurement, the requirement for Abraham to obtain an A– can be represented by the rational number 0.5.
Place the following numbers in order as they would appear on a number line, left to right: −2.0, 0.25, −1.02, 1.98?
On a number line, the numbers would appear in the following order from left to right:
-2.0, -1.02, 0.25, 1.98
Find the sum of p and q if p=34 and q=−114. Reduce your answer to lowest terms?
To find the sum of p and q, we simply need to add the two numbers:
p + q = 34 + (-114)
This can be simplified as:
p + q = -80
Therefore, the sum of p and q is -80.
Add (−12) and (−15).
To add -12 and -15, simply add the numbers together:
-12 + (-15) = -27
Therefore, the sum of -12 and -15 is -27.
Add 10.82+(−15.96).
To add 10.82 and -15.96, simply add the numbers together:
10.82 + (-15.96) = -5.14
Therefore, the sum of 10.82 and -15.96 is -5.14.
Which of the following is a real-world problem that could be solved with the sum 102.50+(−39.95)?
(A)Nevaeh bought new headphones for $102.50. He then spent $39.95 on a new game. How much money did Nevaeh spend all together?
(B)Nevaeh has $102.50 in his bank account. He then deposits $39.95 into his bank account. How much money does he now have in his bank account?
(C)Nevaeh earned $102.50 last weekend. He then spent $39.95 on a new game. How much money from his weekend earnings does he have left?
(D)Nevaeh earned $102.50 last weekend. He then received $39.95 from his mom. How much money does he now have?
The real-world problem that could be solved with the sum 102.50+(−39.95) is:
(A) Nevaeh bought new headphones for $102.50. He then spent $39.95 on a new game. How much money did Nevaeh spend all together?
By finding the sum 102.50 + (-39.95), we can determine the total amount of money Nevaeh spent on the headphones and the game.
It was 13°C yesterday, but the temperature changed by −18.6° overnight. What is the temperature now?
To find the current temperature after the overnight change, we need to subtract the change from the initial temperature.
Temperature now = Initial temperature + Change
Temperature now = 13°C + (-18.6°C)
Temperature now = 13°C - 18.6°C
Temperature now = -5.6°C
Therefore, the current temperature is -5.6°C.
Use the additive inverse to find −492.89−(−871.78)
To find -492.89 - (-871.78), we can use the concept of additive inverse. The additive inverse of a number is the number with the opposite sign. So, the additive inverse of -871.78 is 871.78.
Therefore, -492.89 - (-871.78) can be rewritten as:
-492.89 + 871.78
Now we can proceed with the addition:
-492.89 + 871.78 = 378.89
So, -492.89 - (-871.78) is equal to 378.89.
Determine the distance between −18.26 and −2.45 on a number line
To determine the distance between -18.26 and -2.45 on a number line, you can subtract the smaller number from the larger number and take the absolute value of the result.
|-2.45 - (-18.26)| = |-2.45 + 18.26|
Now we can subtract:
|-2.45 + 18.26| = |15.81|
Therefore, the distance between -18.26 and -2.45 on a number line is 15.81.
Solve the mathematical problem involving absolute value.
2−|13⋅−9|−5
To solve the expression involving absolute value, we start by evaluating the absolute value within the parentheses:
|13 * -9| = |-117| = 117
Now we substitute this value back into the expression:
2 - |13 * -9| - 5 = 2 - 117 - 5
Next, we perform the addition and subtraction:
2 - 117 - 5 = -120
Therefore, the solution to the expression 2 - |13 * -9| - 5 is -120.
Subtract 24−(−15).
What is 1749 + 59 − 8 − 10?
To solve 1749 + 59 - 8 - 10, we can proceed with the addition and subtraction operations:
1749 + 59 - 8 - 10 = 1808 - 18
Now, we can perform the subtraction:
1808 - 18 = 1790
Therefore, the result of 1749 + 59 - 8 - 10 is 1790.

Joey walked east for 1523 meters from home. Then, he walked west for 2134 meters. How far was Joey from home?
To find how far Joey was from home, we need to calculate the total displacement from the origin (home). Displacement is the overall change in position, regardless of direction.
Joey walked 1523 meters east and then 2134 meters west.
To calculate the total displacement, we subtract the distance traveled west from the distance traveled east:
1523 - 2134
This results in a negative value, indicating that Joey is 611 meters west of his home.
Therefore, Joey is 611 meters away from home.
Which situation describes opposite quantities that when combined would equal 0?
(A) A plane ascends to 15,000 feet and then descends 15,000 feet. How many feet above the ground is the plane?
(B) A plane ascends to 15,000 feet and then descends 10,000 feet. How many feet above the ground is the plane?
(C) A plane ascends to 10,000 feet and then ascends 15,000 feet. How many feet above the ground is the plane?
(D) A plane ascends to 15,000 feet and then ascends 15,000 feet. How many feet above the ground is the plane?
The situation that describes opposite quantities that, when combined, would equal 0 is:
(A) A plane ascends to 15,000 feet and then descends 15,000 feet. How many feet above the ground is the plane?
When the plane ascends 15,000 feet and then descends the same amount, the two actions cancel each other out and the net change is 0. Therefore, the plane would be at the same height as the ground, 0 feet above the ground.
Solve the following word problem. The air temperature at 9 a.m. is −5.8 degrees Celsius. The air temperature at noon is −1.6 degrees Celsius. What is the change in the temperature during these three hours? Write and solve an equation to show your answer. Then explain what your answer means.
To find the change in temperature during the three-hour period, we can subtract the initial temperature from the final temperature.
Change in temperature = Final temperature - Initial temperature
Change in temperature = (-1.6) - (-5.8)
Change in temperature = -1.6 + 5.8
Change in temperature = 4.2
Therefore, the change in temperature during these three hours is 4.2 degrees Celsius.
This positive change means that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon.
