Answer:

This table is a guess-and-check, which means that you input whatever number you think might work in this situation in “city gallons”

Step-by-step explanation:

After you just input that same number to wherever the “6” was in the first row...

E.g., if you put “7” for the next “city gallons”, then you’d put “10 - 7 = 3” in “freeway gal” and so on with ever different number you put in for “city gallons”.

That last part in the way bottom goes the same way! Except you input ”c” instead of a number, which is how you find the actual correct answer.

Hope this helps :)

A village water tank contained some water. The villagers used 10300 litre of the water in the day. A pump supplied 12,700 of the water in the tank. There was 16500 litre of water left in the tank in the end. How much water was there in the tank at first?

Answers

Answer:

13830

Step-by-step explanation:

the amount of water that was left is 16500, so substract it to the added amount of water which is 12700, then add 10300 which is the amount of water that the village consumed. 16500-12700=3800+10300=13830

Chris invests $18,000 into an account at an annual rate of 0.4% simple interest for 12 months. 5) Calculate the simple interest earned on this account.

Answers

Answer:do you have a screenshot

The equation we will use is I=PRT
I is the interest, P is the principal, or deposited amount, R is the rate as a decimal, not percentage, and T is time in years.

Convert 0.4% to a decimal by dividing by 100 = 0.004
Convert 12 months into years = 1

I = (18,000)(0.004)(1)
I = 72
$72 interest earned.

In which number does the digit 9 have a value that is 1/10 of the value of the digit in 8.097

Answers

The Value of the digit 9 would be 0.009 or in the thousandths hence 9 thousandths.

STEP BY STEP EXPLANATION:

If this question asks you what is a fraction of a number that means you divide that number. In this instance you divide this number by 10, because you are trying to find the value of this number at 1/10. Once that number is divided by 10 setting every number in that value back one that means that the 9 would move back one space. So instead of making it’s value 9 hundredths, it is now 9 thousandths.
