A scuba diver is 75 feet below sea level. She then ascends 12.7 feet. What is the current depth of the scuba diver?(1 point)
To find Eliana's current score, we can use the expression:
-12 + 7
This expression represents adding (-12) to 7, which will give us her current score in the game.
You're welcome! If you have any more questions in the future, feel free to ask. Goodbye!
wrong its -62.3 😈😈😈
Apologies for the error.
The correct sum is 5/8, not 3/8.
So, the sum of 1/8 + 1/2 = 5/8.
In the context of the problem, the sum 5/8 represents the total amount of mixture Micah will have for sprinkling on toast. It represents five parts out of a total of eight parts of the cinnamon and sugar mixture.
To find the temperature now, we need to add the change in temperature to the initial temperature.
-3°C (initial temperature) + 13°C (change in temperature) = 10°C
Therefore, the temperature now is 10°C.
correct! bye
i will
all correct thx botttt
hey bot, i need help!!

The current depth of the scuba diver is 87.7 feet.
LESSON 4
Applications of Adding Rational Numbers
In Lesson 4, we will learn about the applications of adding rational numbers. Rational numbers include fractions and decimals. Adding rational numbers is useful in many real-life situations, such as measuring distances, temperatures, or quantities of objects.
For example, let's consider a scuba diver who is 75 feet below sea level. If the scuba diver ascends 12.7 feet, we can find the new depth by adding the two numbers.
75 feet (current depth) + 12.7 feet (ascend) = 87.7 feet
Therefore, the current depth of the scuba diver is 87.7 feet.
Adding rational numbers is a fundamental skill in mathematics that helps us solve problems and make accurate calculations in various scenarios.
Apologies for the confusion earlier. If a scuba diver is 75 feet below sea level and then ascends 12.7 feet, the current depth of the scuba diver would be -62.3 feet. The negative sign indicates that the diver is still below sea level. Thank you for pointing out the error.
Eliana is playing a card game with her cousins. At the start of this turn, she had −12 points in the game. On this turn, she gets 7 points. Write an expression that shows how to find her current score.(1 point)
are you sure?
Apologies for the mistake. The correct expression to find Eliana's current score would be:
(-12) + 7
So her current score would be -5.
Micah is making a cinnamon and sugar mixture to sprinkle on toast. His recipe uses 1/8 cup of cinnamon and 1/2 cup of sugar. Find 1/8+1/2 and interpret this sum in the context of the problem. (1 point)
To find 1/8 + 1/2, we need to add the two fractions:
1/8 + 1/2 = 3/8
In the context of the problem, this sum represents the combined amount of cinnamon and sugar that Micah will use in the mixture for sprinkling on toast. The sum, 3/8, represents three parts out of a total of eight parts, indicating the ratio or proportion of the cinnamon and sugar in the mixture.
1/8 cup,1/2 cup , 5/8, 1
Solve the following problem:
It was −3°
C this morning, but the temperature has gone up 13°
over the course of the day. What is the temperature now?
are you correct
Apologies for the mistake.
To find the temperature now, you would add the change in temperature to the initial temperature.
-3°C (initial temperature) + 13°C (change in temperature) = 10°C
Therefore, the temperature now is 10°C.
Solve the following problem:
Samuel has $58.23 in his bank account. He withdraws $39.78. How much is in his bank account now?
To find out how much is left in Samuel's bank account, we need to subtract the amount he withdrew from the initial balance.
$58.23 (initial balance) - $39.78 (amount withdrawn) = $18.45
Therefore, there is $18.45 left in Samuel's bank account now.
Goodbye! Have a great day!
Zuri earned $56.80 at his job last week. They then spent $40 on a video game. 56.80+(−40)=16.80. Interpret this sum in the context of the problem.
The sum of $56.80 + (-40) = $16.80 represents the remaining amount of money that Zuri has after spending $40 on a video game.
In the context of the problem, Zuri initially earned $56.80 from his job. However, after spending $40 on a video game, he is left with $16.80. This means that he has $16.80 remaining from his earnings after the video game purchase.

Solve the following problem:
It was −8°F this morning, but the temperature has gone up 11° over the course of the day. What is the temperature now?
1. −3°F
2. 3°F
3. 11°F
4. 19°F
To find the current temperature, we need to add the change in temperature to the initial temperature.
-8°F (initial temperature) + 11°F (change in temperature) = 3°F
Therefore, the temperature now is 3°F.
The correct response is option 2: 3°F
There are some areas of land on Earth that are below sea level. Imagine you are at the Dead Sea in Africa, which has an elevation of about −1,410 feet (1,410 feet below sea level). You then climb up 125 feet. What is your new elevation?(1 point)
Responses
1. 1,285 feet
2. −1,535 feet
negative 1,535 feet
3. −1,285 feet
negative 1,285 feet
4. −1,335 feet
To find the new elevation, we need to add the change in elevation to the initial elevation.
-1,410 feet (initial elevation) + 125 feet (change in elevation) = -1,285 feet
Therefore, the new elevation is -1,285 feet.
The correct response is option 3: -1,285 feet.
Reem owes her friend $15.25. Reem works after school and earns $43.78. After paying her friend back, how much money does she have?(1 point)
Responses
1. −$59.03
negative $59.03 dollars
2. $59.03
$59.03
3. −$28.53
negative $28.53 dollars
4. $28.53
To find out how much money Reem has after paying her friend back, we need to subtract the amount she owes from her earnings.
$43.78 (earnings) - $15.25 (amount owed) = $28.53
Therefore, Reem has $28.53 left after paying her friend back.
The correct response is option 4: $28.53.
