\underline{\bf 5y^2\:\; when\;\; y=3}

Substitute y with 3.

  • \bf 5(3)^2

Calculate 3 the power of 2 = 9

  • \bf 5\times 9
  • \bf 45

⇒ ⇒ ⇒

\underline{\bf  5y^2\:\; when\;\; y=-3}

Substitute y with -3.

  • \bf 5\left(-3\right)^2

Calculate -3 to the power of 2 = 9

8 5/6 rounded to the nearest whole number
german

Answer: 9.

Step-by-step explanation:

8 5/6 is a mixed number with a whole number and a fraction. We want to round to the nearest whole number without the fraction.

First, we convert the mixed fraction to an improper fraction or fraction like this:

((8 x 6)+5)/6 = 53/6

Then, we divide the numerator by the denominator from the previous step:

53/6 = 8.83

Now we have one decimal number. Round using the following rules:

If the number to the right of the decimal point is .5 or higher, then add 1 to the left of the decimal point.

If the number to the right of the decimal point is less than .5, then leave the number to the left of the decimal point as is.

.83 is .5 or higher. Thus, we add 1 to the left of the decimal point. 8 5/6 rounded to the nearest whole number is therefore the answer will be 9.

Lyle bought 3/8 pound of red grapes and 5/12 of green grapes. How many pounds of grapes did he buy ?
STatiana [176]
He bought 19/24 pounds of grapes.
You need to find the common denominators then add.

3/8 = 9/24 - Red grapes
5/12 = 10/24 - Green grapes

10/24 + 9/24 = 19/24.
Therefore, he bought 19/24 pounds of grapes.
Hope this helped! :-)
