Answer:
[tex]c=35r+10[/tex]
Step-by-step explanation:
We need to create a linear equation in the form: c = mr + b
(where m is the slope and b is the y-intercept)
Choose two ordered pairs from the table: (2, 80) and (4, 150)
Let [tex](r_1,c_1)[/tex] = (2, 80)
Let [tex](r_2,c_2)[/tex] = (4, 150)
Calculate the rate of change (slope of linear equation) by dividing the change in c by the change in r:
[tex]\textsf{slope} \ m=\dfrac{c_2-c_1}{r_2-r_1}=\dfrac{150-80}{4-2}=35[/tex]
Now use point-slope form of linear equation to create final equation:
[tex]c-c_1=m(r-r_1)[/tex]
[tex]\implies c-80=35(r-2)[/tex]
[tex]\implies c=35r+10[/tex]

The cost of a sweatshirt is 175% the cost of a T-shirt. A T-shirt costs $13.
What is the cost of 3 sweatshirts?
Enter your answer in the box.
Answers
Answer:A standard blank t shirt will usually start at around $1 each and go up to $4. These are going to be cotton, good quality shirts. The price difference will vary on manufacturer, brand, color and cut. So a plain white t shirt might only be $1, where the same shirt in navy blue might be $2.
Step-by-step explanation:
If you want a profit of 50% off the retail price, the calculation is straightforward. Let's say the production cost of your t-shirt amount to ₹300. When you multiply it by two, you get ₹600. And that would be the retail price of each t-shirt piece

What is the percent of change from 5 to 8?
Answers
Answer:
60%
Step-by-step explanation:
5-8/5 * 100%= 60%
The percentage change from 5 to 8 is given by A = 60 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage change be represented as A
Now , the equation will be
Let the first number be p = 5
Let the second number be q = 8
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
On simplifying the equation , we get
Percentage change A = [ ( 8 - 5 ) / 5 ] x 100
Percentage change A = ( 3/5 ) x 100
Percentage change A = 60 %
Hence , the percentage change is 60 %

g(x) = -3x - 3
To complete the table, you have to substitute the x values into the equation.
g(-5) = -3(-5) - 3
g(-5) = 15 - 3
g(-5) = 12
g(-3) = -3(-3) - 3
g(-3) = 9 - 3
g(-3) = 6
g(0) = -3(0) - 3
g(0) = 0 - 3
g(0) = -3
g(1) = -3(1) - 3
g(1) = -3 - 3
g(1) = -6
g(3) = -3(3) - 3
g(3) = -9 - 3
g(3) = -12

what is 3 times 34 divided by 2 plus 8 times 5
Answers
multiplied 3x34=102 divided by 2 is 51 plus 40 because 8x5 is 91
Answer: 91
Step-by-step explanation: 3 times 34 is equal to 102... let us work out the problem together.
3 x 34 = 102
now we must divided 102 by 2 which will equal 51
Now the final step is to do 8 times 5
8 times 5 = 40
51 plus 40 = 91
this is the correct way to do the equation.
so our final answer is 91
A card was selected at random from a standard deck of cards. The suit of the card was recorded, and then the card was put back in the deck. The table shows the results after 40 trials. What is the relative frequency of selecting a diamond?.
Answers
The relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.
What is relative frequency?The relative frequency of an event is the ratio of total number of favorable or desired outcome to the total number of trails done.
Given information-
The card is selected random from the deck of cards.
Total number of trails is 40.
It is known that the total number of diamond card in a standard deck of card is 11. There is total 40 trials is done in which a random card is selected.
As the relative frequency is the ratio of total number of diamonds to the total number of trials done. Thus,
[tex]f_r=\dfrac{11}{40}\\f_r=0.3[/tex]

Which expression represents the greatest common factor (GCF) of 54 and 153?
Answers
Answer:
9
Step-by-step explanation:
Factors are numbers we can multiply together to get another number.
A common factor is one that is a factor of two (or more) numbers.
The greatest common factor (GCF) is the largest of the common factors.
There are a few ways to find the GCF. One way is to find all the factors of both numbers, then find the ones that are common to both and choose the greatest:
The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54
The factors of 153 are: 1, 3, 9, 17, 51, 153
Therefore, the greatest common factor is 9.
The expression which represents the greatest common factor (GCF) of 54 and 153 is 3×3. Correct option is B.
The greatest common factor (GCF) of two numbers is the largest positive integer that divides both numbers evenly.
To find the GCF of 54 and 153, we need to determine the common prime factors of these two numbers and then multiply those factors together.
The prime factorization of 54:
= 2 × 3 × 3 × 3
= 2 × 3³.
The prime factorization of 153:
= 3 × 3 × 17
= 3² × 17.
The common prime factors of 54 and 153 are two factors of 3, so the GCF is 3 × 3, which can be written as 3².
Hence, 3 × 3 is the expression which represents the greatest common factor (GCF) of 54 and 153. Option B is correct.
