Shawna has been saving and now has exactly enough money to pay for the pink carpet that she wants in her room. She has $219.70. Each wall in her room has a length of 13 feet. a) How many square feet of carpet will she need? b) What is the cost for each square foot of carpet?
Answer:
169 feet²
$1.30
Step-by-step explanation:
Given that :
Amount Shawna has = exact cost of carpet = $219.70
Length per wall = 13 feets
a) How many square feet of carpet will she need?
Number of square feet of carpet :
13 feets * 13 feets = 169 feet²
B.) Cost of each square foot :
Total cost / number of square feet
$219.70 / 169 feet²
= $1.30

At Zach's auto shop each mechanic can change the oil 3 cars per hour. Zach can have up to 4 mechanics working at a time. In a relationship between number of oil changes per hour and number of mechanics working identify the independent variable dependent variable domain and range
Answer:
We know that:
Each mechanic can change the oil of 3 cars per hour.
The number of mechanics can change between 0 and a maximum of 4.
Then we can write the variable:
Y = number of oil changes per hour.
Y = 3*X
Where X is the number of mechanics working.
The independent variable is X (number of mechanics), because is the one that Zach can change, and the dependent is Y (number of oil changes) because this depends on the value of X.
Now, the domain will be: {0, 1, 2, 3, 4}
The possible numbers of mechanics working at the same time.
And for the range we must replace those values in our equation, and see the possible values of Y.
Y(0) = 3*0 = 0
Y(1) = 3*1 = 3
Y(2) = 3*2 = 6
Y(3) = 3*3 = 9
Y(4) = 3*4 = 12
Then the range is: {0, 3, 6, 9, 12}

Find the slope between (2, -1) and (2,5) by graphing or solving..
Answer:
Step-by-step explanation:
I think the easiest way would be to plot the points onto a graph. See the attached graph.
If you want to solve it, you can use the slope formula:
[tex]m = \frac{y2-y1}{x2-x1}[/tex]
Where m = slope
From the two points we are given:
(2, -1) -----> x1 = 2 , y1 = -1
(2,5) -----> x2 = 2 , y2 = 5
Plug these values into the slope formula and you get:
[tex]m = \frac{y2-y1}{x2-x1}[/tex]
m = [tex]\frac{5 - (-1)}{2 - 2}[/tex] = [tex]\frac{5 + 1}{0} = \frac{6}{0}[/tex] = ∞
This means that the slope m = ∞. In other words, there is no slope or gradient because the line is vertical.

20 Points and Brainliest for the person who will get it correct which table represents the equation y=9x
Answer:
[C]
Step-by-step explanation:
Since y = 9x
So x need to be a number that will multiply and y = 9
Going through all answer choices
since it y = 9
We can see that [A} and [B] is wrong
Now [C] and [D]
We can see that [D] is wrong because it shows that x = 9 when y = 9
that left us with [C]
[C] shows x = 1 and y = 9
Which is True
1 * 9 = 9
2 * 9 = 18
3 * 9 = 27
Hence, [C] is the correct Answer

Zack is creating a 5 digit password for his computer. For the first three digits, he chooses different letters of the alphabet.
For the last two digits, he chooses a different number
between 0-9. How many passwords are possible?
Answer:
460
Step-by-step explanation:
The total number of passwords possible is given by the permutation equation A = 26 x 25 x 24 x 10 x 9
What are Permutations?A permutation is an ordered arrangement.
The number of ordered arrangements of r objects taken from n unlike objects is:
Permutation nPr = ( n )! / ( n - r )!
Given data ,
Let the total number of passwords be represented as A
Now , the equation will be
The number of digits in the password = 5 digits
For the first three digits, he chooses different letters of the alphabet
So , total number of digits that are alphabets out of the 26 alphabets = 3
For the last two digits, he chooses a different number
between 0-9
The total number of digits that are numbers out of the 10 numbers = 2
So , the permutation will be
A = 26P3 x 10P2
Substituting the values in the equation , we get
The total number of passwords A = ( 26 )! / ( 26 - 3 )! x ( 10 )! / ( 10 - 2 )!
On simplifying the equation , we get
The total number of passwords A = ( 26 )! / ( 23 )! x ( 10 )! / ( 8 )!
And ,
The total number of passwords A = 26 x 25 x 24 x 10 x 9
Therefore , the value of A is 14,04,000
Hence , the permutation is 26P3 x 10P2

What is the solution set of an inequality? Use the inequality x > 10 as an example.
Answer:
x can be any number greater than 10, there are infinite solutions.
>, meaning x is greater than 10
The solution set to the inequality equation x > 10 has infinite number of solutions as x can have any value greater than 10
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
x > 10 be equation (1)
So , the value of x is given by set P = { 11 , 12 , 13 , 14 ... }
Therefore , the value of x is any number greater than 10 and the inequality relation has infinite number of solutions
Hence , the inequality equation is x > 10

Step-by-step explanation:
There are 15 2-liter bottles, so you must get the total number of liters by multiplying 15 and 2 to get 30. Then, because there are 1,000 milliliters per liter, you multiply 30 by 1,000 to get 30,000 milliliters total.

Graph the line.
x = 3
Explanation: I would do this problem by setting up a chart.
For the equation x = 3, if we set up a chart for x and y,
since x must be equal to 3, the random values we
choose in this problem are not for x, they are for y.
If we had an equation like y = 2x + 3, then we would pick values for x
and plug them into the equation to get y, but here, x is our only value.
So let's choose the values 1, 0, and -1 for y.
For each of these values, x must be equal to 3.
So we have the points (3, 1), (3,0), and (3, -1).
Notice that our graph is a vertical line, as I showed this below.

Answer:
k-10>12
Step-by-step explanation:
the word difference means subtraction and since k comes first that means you have to subtract 10 from k and greater than means that the greater than or less than sign will face k-10,so you would have the equation k-10>12
The cost of laying wood floors consists of a base price of $250, plus $3.50 for each square foot installed. Define the variable
Let s = the base price of laying wood floors
Let s = the cost of each square foot
Let S = each square foot of wood installed
Let s = $250
Answer:
Let s = each square foot of wood installed
Step-by-step explanation:
Total cost of laying wood = base price + price for each square foot installed
Base price = $250
Price for each square foot installed = $3.50
Let
s = number of each square foot installed
Total cost of laying wood = $250 + $3.50s
The correct answer is
Let s = each square foot of wood installed
