5.) The price of gas last year was $1.75 per gallon. The price went up by 5%,
what is the new price for a gallon of gas?
Answer: 1.75•5%=0.0875
1.75+0.0875=$1.84
I’m pretty sure this is correct
Answer:
5% of 1.75 is 0.085.
So 1.75 + 0.085 is 1.8375.

A(n) sampling method is one that is representative of the population, selected at random, and large enough to provide accurate data.
A sample is one that is representative of the population, selected at random, and large enough to provide accurate data.
What is a sample?A sample is a smaller group that is representative of the population. A sample is sometimes necessary because it might not be feasible or cost effective to access the whole population.
For example, if a researcher is studying the impact of inflation on US families. It is not feasible to reach the whole of the families in the US. So, the researcher would use a representative group of US families. This is known as a sample.

Part A
The pattern of squares is 1, 4, 9, ... which is the set of perfect squares
1 = 1^24 = 2^29 = 3^2and so on
The 7th figure will have 49 squares because 7^2 = 49
Answer: 49==============================================================
Part B
Each pattern has one circle per corner (4 circles so far). In addition, there's one circle per unit side to form the perimeter.
Pattern 1 has 4+4(1) = 8 circlesPattern 2 has 4+4(2) = 12 circlesPattern 3 has 4+4(3) = 16 circlesThe nth term will have 4+4n circles. The first '4' is the number of circles at the corners. The 4n is the circles along the perimeter. If you wanted, 4+4n factors to 4(1+n).
Plug in n = 20 to find the 20th figure has 4+4n = 4+4(20) = 84 circles
Answer: 84==============================================================
Part C
Pattern 1 has 1 square + 8 circles = 9 items totalPattern 2 has 4 squares + 12 circles = 16 items totalPattern 3 has 9 squares + 16 circles = 25 items totalThis seems to suggest if the pattern number is odd, then we need an odd number of tiles (square + circular).
Let n be the pattern number. Pattern n needs n^2 square tiles and 4+4n = 4n+4 circular tiles. Overall, n^2+4n+4 tiles are needed.
It turns out that if n is odd, then n^2+4n+4 is always odd. The proof is shown below.

It is the middle of the heatwave, and you AC unit has broken. You have 2 companies that come highly qualified. Company A charges $200 to come out plus $50 per hour to look at your AC and determine what is wrong. Company B charges $125 plus $75 an hour for the same exact service.
After how many hours (x) will both companies charge you the same amount(y)?
By solving a linear equation, we will see that after 3 hours, both companies will charge the same amount.
After how many hours will both companies charge you the same amount?
We know that company A charges $200 plus $50 per hour. So if they work for x hours, they charge:
A(x) = $200 + $50*x
And company B charges $125 plus $75 per hour, so if they work for x hours, they charge:
B(x) = $125 + $75*x
We want to find the value of x such that A(x) = B(x), then we want to solve the linear equation:
$200 + $50*x = $125 + $75*x
$200 - $125 = $75*x - $50*x
$75 = $25*x
$75/$25 = x = 3
This means that after 3 hours, both companies will charge the same amount.

Aurelio is purchasing carpet tiles to cover an area of
his living room floor that is 8 feet wide by 10 feet
long. each carpet tile is a square 20 inches wide by
20 inches long. what is the minimum number of carpet
tiles that aurelio must purchase to cover this area of
his living room floor?
a. 5
b. 11
c. 21
d. 30
e. 84
Answer:d.33
Step-by-step explanation: To begin we convert his living room floor length and width to inches. 8 1 slash 3 feet = 100 inches
10feet= 120 inches
hence the area in square inches of the living room floor is 100 inches times120 inches = 12000 inches squared.
Each carpet tile has an area of 20 by 20 which = 400inches squared. dividing the area of the living room by 400inches of each carpet tile, would yield 30 carpet tiles needed to cover this area.
As per linear equation, the minimum number of carpet tiles that Aurelio must purchase to cover the area of his living room floor is 29.
What is a linear equation?A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.
Given, the room has a length of 10 feet = 12 × 10 inches = 120 inches
The width of the room is = 8 feet = 12 × 8 inches = 96 inches
Therefore, the area of the room is
= 120 × 96 square inches
= 11520 square inches
Length of each carpet tile is 20 inches
Width of each carpet tile is 20 inches
Therefore, the area of each tile is
= (20)² square inches
= 400 square inches
The number of tiles require
= (11520/400)
= 28.8
≈ 29
Therefore, 29 tiles will be required.

One number is 4 times another. Their difference is 27. How to get the other two numbers?
Answer:
x = 36; y = 9
Step-by-step explanation:
To solve this problem you need to set up two equations. The first equation comes from the first sentence "One number is 4 times another." This equation can be written as x = 4*y where x and y are the two numbers. The second equation comes from the second sentence "Their difference is 27." This equation can be written as x-y = 27. To find the numbers you need to rearrange one equation and plug it into the other.
Step 1: write equations
x = 4*y
x-y = 27
Step 2: rearrange
Not necessary here
Step 3: substitute in
x - y = 27
4y -y = 27
3y = 27
y = 9
Step 4: solve for x
x = 4*y
x = 4*9
x = 36
[tex]x[/tex] - one number
[tex]4x[/tex] - the other number
[tex]4x-x=27\\3x=27\\x=9\\\\4x=4\cdot9=36[/tex]
These numbers are 9 and 36.

Answer: The value of x is 3.5
Explanation:
Equation:
y = 2x - 7
When the equation's Line intersects the x-axis, the value of y shall be always 0
Insert y = 0, to find x intercept
⇒ 0 = 2x - 7
⇒ 2x - 7 = 0
⇒ 2x = 7
⇒ x = 3.5
So coordinates: (x, y) → (3.5, 0)

Answer:
Step-by-step explanation:
John is buying a new car. The value of one car he is considering is $20,000. The value of the car as it ages can be modeled by the
function v= 20,000(0.84), where t is the number of years from the time of purchase. One of the factors John is using to make his decision is
the value of the car over time until it reaches half its original value. What values of domain are reasonable for the given function in this
context?
The reasonable domain of the function is [0,4)
How to determine the domain?The function of the car value is given as:
V(x) = 20000 * (0.84)^x
When the car reaches half its value, we have:
V(x) = 10000
Substitute V(x) = 10000 in V(x) = 20000 * (0.84)^x
10000 = 20000 * (0.84)^x
Divide both sides by 20000
0.84^x = 0.5
Take the logarithm of both sides
x log(0.84) = log(0.5)
Divide both sides by log(0.84)
x = 4
This means that the maximum value of x is 4
Hence, the reasonable domain of the function is [0,4)
