Ok, 7, 6, 5, and 4 are the integers.

Work - So, if you add 7 and 6 you get 13, and the problem tells you to multiply that by 2. After you multiply by 2, you should get 26, after getting that you move 2 numbers before 7 and 6, you should get to 4, the problem also tells us to make sure you multiply it by 3 but make it 14 less than you answer. Therefore, after doing the work you should receive the number 12, if you get your previous number, in our case, 26, you need to then, subtract 12 away from 26, and you should get 14 (the number you should be left with).

This is correct, Have a good day Mr. Abc

Angel has finished 75% of an art project that has taken him a total of 9 hours so far. If he continues to work at the same rate, how many hours will it take for him to complete the entire project?

Answers

Just did the math! 75 percent is 75/100 and since you are trying to find the total amount of hours, its 9/?. How do you get 75 to 9? You divide by 8.3! 100/8.3 is 12.048, which rounds up to 12! It takes him 12 hours to complete his work!

The time taken to complete the entire project is 12 hours.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

75% = 9 hours

The entire project = 100%

So,

75% = 9 hours

Multiply 100/75 o on both sides.

100% = 100/75 x 9 hours

100% = 12 hours

Thus,

12 hours to complete the entire project.

The warmest lake is Lake C and the coldest lake is Lake A.

We have the lake temperature in degrees Celsius as follows -

Lake A : -2 °C

Lake B : 0 °C

Lake C : 2 °C

Lake D : -1 °C

We have to determine -

The coldest lake's temperature and the warmest lake has a temperature.

What is Temperature ?

It is the measure of hotness or coldness of a body which is expressed via some arbitrary scales.

An object with high temperature is warmest and the one with low temperature is the coldest. Now, According to question -

Lake C has the highest temperature of : +2°C, hence it is the warmest.

Lake A has the lowest temperature of : -2°C, hence it is the coldest.

Hence, the warmest lake is Lake C and the coldest lake is Lake A.
