what is the area of the rectangular pool below whose dimension are 2 x +1 and units x-1 units
Answer:
(2x+1)(x-1) = 2x^2 - x - 1
Step-by-step explanation:
Answer:
2x^2 - x - 1
Step-by-step explanation:
Lets rewrite it to the area formula
(2x+1)(x-1)
Simplify-(distributive property of multiplication)
(2x*x) + (2x*-1) + (1*x) + (1*-1) =
Simplify
2x^2 + (-2x) + x + (-1)
Simplify
2x^2 - x - 1
The answer is 2x^2 - x - 1

A board game has a spinner divided into sections of equal size. Each section is labeled with a number between 1 and 5.
Spinner
Which number is a reasonable estimate of the number of times the spinner will land on a section labeled 5 over the course of 150 spins?
Answer:
30 times
Step-by-step explanation:
1. find the possibility of the spinner landing on each section
1 / 5 = 0.2
2. multiply # of spins by the possibility
150 * 0.2 = 30 times

Simplify the following expressions to have fewer terms 5x-3+4(4x-6)+2
Answer:
(21x-25)
Step-by-step explanation:
We need to find an equivalent expression for the following.
5x-3+4(4x-6)+2
We can solve it as follows:
5x-3+4(4x-6)+2 = 5x-3+16x-24+2
= 5x+16x-3-24+2
= 21x-25
So, the equivalent expression is equal to (21x-25).
») What is the circumference of the rim of a basketball hoop with a radius of 9 inches? First, multiply the radius by__ to get the diameter__ inches. Then, multiply the diameter by 3.14 (an approximation for 1) to get a circumference of
about__ inches. ») Convince Me! If the diameter is doubled, what happens to the circumference? Explain.
Answer:
First, multiply the radius by 2 to get the diameter 18 inches. Then, multiply the diameter by 3.14 (an approximation for 1) to get a circumference of about 56.52 inches. If the diameter doubles the circumference doubles.
Step-by-step explanation:
18π = 56.52
36π = 113.04
56.52*2 = 113.04

The longest run way at an airport has the shape of a rectangle and an area of 1,573,000 sq ft. This run way is 130 feet wide. How long is the run way?
Answer:
12,100 feet
Step-by-step explanation:
The longest run way at an airport has the shape of a rectangle and an area of 1,573,000 sq ft. This run way is 130 feet wide. How long is the run way?
The area of a rectangle = Length × Width
Width = 130 feet
Area = 1,573,000 sq ft
The Length = Area/Width
= 1,573,000 sq ft/130 feet
= 12,100 feet
Therefore, the runaway is 12,100 feet long.

The area of the carpet is 48x^2y+16xy^2, if the width is 8xy inches, what is the length of the carpet?
Answer:
Step-by-step explanation:
(48x^2)(y) + (16x)(y^2).
This is addition, so the distributive property applies. [(48x^2)(y) + (16x)(y^2)]/8xy = (48x^2)(y)/8xy+(16x)(y^2)/8xy = 6x+2y.
Division rules are explained below.
I included the parentheses to emphasize the difference between x^2y, which means x to the 2y, and (x^2)(y), which is x^2 times y.
48/8 = 6x^2 times y divided by 8xy equals x because x^2/x = x^(2-1), because x=x^1, and so, equals x; The same y^2/y. The other 2 y's and 2 x's cancel.

Step-by-step explanation:
when dividing exponents with the same base (the number on the bottom) you subtract the exponents.
Decide whether the given expression is a polynomial and tell why or why not.
5. 3x2 – 5x + 2
Answer:
3x² – 5x + 2 is a polynomial because:
Exponents are whole numbers, and the expression has at least 1 term.
Exponents other than whole numbers can take the form of variables in denominators, and roots which we don't want.

HELP ME PLEASE! its very hard and i need it for tonight!!
Answer:
288 cm
Step-by-step explanation:
The formula to solve this polygon is: area = 1/2 x perimeter x apothem
To find the perimeter all you have to is find the sum of all sides together: 12+12+6+6+6+6= 48
Then the Apothem is, the "segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side." To find this you find the point from the middle to the edge which is 12cm.
Then you plug in this information into the polygon. 1/2 x 48 x 12= 288!
The polygon is 288 cm!

Answer:
402 in^3
Step-by-step explanation:
We know that the volume of a sphere = 4 /3 πr^3
Variables:
r = 2in
Solve for 1 toy:
4 /3 πr^3
4/3 π (2in)^3
= 33.51 cubic inches for 1 toy
For 12 toys:
33.51 in^3 * 12 toys = 402.12 in^3 of water for all the toys
Round:
402.12 in^3 ≈ 402 in^3 of water
