Convert 8.132132132 ... to a rational expression in the form of a over b , where b ≠ 0. (4 points)

Butoxors [25]

8 would become the whole number, since there are 3 repeating numbers you would put those over 999.

So you would get 8 and 132/999

Factor f(x)=x4+x3-20x2.

Leya [2.2K]

Hello from MrBillDoesMath!

Answer:

-5, 0 (multiplicity 2), +4

Discussion:

Let f(x) = x^4 + x ^3 - 20 x^2

Factor x^2 from each term:

f(x) = x^2 ( x^2 + x - 20) = x^2 ( x +5) (x-4)

f = 0 when x = 0 (multiplicity 2) and x = -5 or x = 4

You need to order cement to make a concrete sidewalk 3 feet wide and 95 feet long. Assume that the depth of the concrete is 4 in

11Alexandr11 [23.1K]

Answer:

3.5 cubic yards of cement we need.

Step-by-step explanation:

Given : You need to order cement to make a concrete sidewalk 3 feet wide and 95 feet long. Assume that the depth of the concrete is 4 inches.

To find : How much cement is needed, in cubic feet? How many cubic yards of cement do you need?

Solution :

The length of the side walk is 95 feet long.

The width of the side walk is 3 feet long.

The depth of the concrete is 4 inches.

Convert inches into feet,

1 inch = 0.083 feet

4 inch = $4\times 0.083=0.332$ feet

Volume of the cement required is given by

$V=l\times b\times h$

$V=95\times 3\times 0.332$

$V=94.62\ ft^3$

Converting volume into yards,

$1\ ft^3=0.037\ yd^3$

$94.62\ ft^3=3.50094\ yd^3$

Therefore, 3.5 cubic yards of cement we need.
