Show all your work 9)  23.32 x 7.1    10) 2,772 divided by 85 plzz

This is posted in the College Math section, so we presume you have access to a calculator. (We know you have access to the internet, which has myriad calculators available.) The work of using a calculator is shown in the first attachment.

The work of doing these by hand is shown in the second attachment. There is a certain amount of mental math that goes with the written numbers.

9) The product will have 3 decimal digits. That number is found by adding the 2 decimal digits of the first number to the 1 decimal digit of the second number: 2+1=3. Otherwise, the multiplication is the same as for integers.

... 23.32×7.1 = 165.572

10) Each quotient digit is multiplied by the divisor, and the result subtracted from the dividend. The next digit of the original dividend is brought down to form the dividend for the next stage. The sequence of steps is repeated as long as you like. The decimal fraction has a 16-digit repeat, the repeating digits starting with 1176....

... 2772÷85 ≈ 32.61776

answer: -1

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
