A T-shirt department store cost 7.50.the total cost in dollar of a T-shirt is givien by the function C(a)=7.5a
Given cost function C(a) = 7.5a, where a is the number of T-shirts.
Let us complete table.
We need to plug a=1,2,3,4 in above function to get the costs to complete the table.
For a =1
C(1)= 7.5(1) = 7.50
For a =2
C(2)= 7.5(2) = 15.00
For a =3
C(3)= 7.5(3) = 22.50
For a = 4
C(4)= 7.5(1) = 30.00
In order to find the common difference we need to find the diffrences of costs 15-7.50 = 7.50
22.50-15.00=7.50.
Therefore, common difference is 7.5.a represents the number of T-shirts.
Domain of a is the numbers we can take for a.
So, we can take value for a as 0 or greater value.
Therefore, domain for a would be a is gerater than or equal to 0.
Domain : a≥0Nicole is running for school president. Her best friend designed her campaign poster, which measured 3 feet by 2 feet. Nicole liked the poster so much, she reproduced the artwork on rectangular buttons that measured 2 inches by 1 1/3 inches. What is the scale factor as a fraction (and how would I do this!?)
[tex]\frac{3 (ft)}{2(in)} by \frac{2(ft)}{\frac{4}{3}(in)}[/tex]
= [tex]\frac{3 (ft)}{2(in)} by \frac{2(3)(ft)}{4(in)}[/tex]
= [tex]\frac{3 (ft)}{2(in)} by \frac{3(ft)}{2(in)}[/tex]
Scale factor is: [tex]\frac{3(ft)}{2(in)}[/tex]
Answer:
9/16 is the scale factor.Step-by-step explanation:
Every transformation has an original figure and a transformed figure.
In order to find the scale factor fo the transformation, we need to divide the transformed dimensions by the original ones.
So, in this case, the poster originally had 3 feet by 2 feet. Then, the reproduced artwork has 2 inches by 1 1/3 inches. Before we divide, we need to transform feet to inches.
We know that 1 feet equals 12 inches, that means
[tex]3ft \frac{12in}{1ft} =36in[/tex]
[tex]2ft\frac{12in}{1ft}=24in[/tex]
Then, we do the divisions
[tex]\frac{36in}{2in}=18\\\frac{24in}{1\frac{1}{3}in }=\frac{24in}{\frac{4}{3}in }=\frac{96}{3}=32[/tex]
Therefore, the scale factor is [tex]\frac{18}{32}=\frac{9}{16}[/tex]

A store sells 2 1/4 pounds of tomatoes in a package for $4.45. The expression 4.45p represents the cost of the tomatoes for a number of packages. What does the variable p represent?
Answer:
The variable p represent the number of packages.
Step-by-step explanation:
As 4.45 is the cost of tomatoes, and 4.45p represents the cost of the tomatoes for a number of packages, we can say that p represent the number of packages.
Three friends all have same ages that are consecutive integers. The sum of their ages is 180. What is the age of the oldest friend?
a) 61
b) 59
c) 62
d) 60
Answer:
a) 61
The friend's ages are consecutive, therefore they are each one year apart. There are 3 friends whose ages add up to 180 in total.
[tex]180 / 3 = 60[/tex]
In order to make three consecutive numbers, subtract one and add one to 60.
[tex]60 - 1 = 59\\60 + 1 = 61[/tex]
You get 59, 60, and 61.
61 is the oldest age, that's your answer.
to make a shade of plant called Jasper Green, Mix 4 quarts of green paint with 2/3 cups of black paint. how much green paint should be mixed with 4 cups of black paint to make Jasper Green?
Answer
24 quarts of green paint should be mixed with 4 cups of black paint.
That is (96 cups)
Step by step explanation
Jasper Green mix 4 quarts of green paint with 2/3 cups of black paint.
Let's convert 4 quarts into cups.
1 quart = 4 cups
4 quarts = 16 cups
Here mix 16 cups of green paint with 2/3 cups of black paint.
Let's use the proportion
Green paint Black paint
16 2/3
x 4
16/x =2/3 divided by 4
[tex]\frac{16}{x} = \frac{2/3}{4}[/tex]
Cross multiplying, we get
16*4 = 2/3 x
64 = 2/3 x
x = 64/(2/3)
x = 64 * 3/2
x = 192/2
x = 96 cups
96 cups of green paint should be mixed with 4 cups of black paint.
We can covert 96 cups into quarts by dividing by 4
96/4 = 24 quarts
24 quarts of green paint should be mixed with 4 cups of black paint.
Thank you.
To make Jasper Green with 4 cups of black paint, you need to create a proportional relationship and solve for the amount of green paint needed, which is 96 cups.
Explanation:To solve this, we need to set up a proportional relationship between the amounts of green paint and black paint. In the first mixture, we have 4 quarts of green paint for every 2/3 cups of black paint. Converting 4 quarts to cups (since 1 quart = 4 cups), we get 16 cups of green paint.
Then we can set up the proportion: (16 cups green / 2/3 cups black) = (x cups green / 4 cups black). Cross multiplying and solving for x, we get x = 96 cups of green paint. So, to make Jasper Green with 4 cups of black paint, you need to mix in 96 cups of green paint.

HELP ME PLEASE!!! 2(b+3)-(7+b)=-7 ??
2(b + 3) - (7 + b) = -7
2b + 6 - 7 - b = -7
b = -6 + 7 - 7
b = -6
To solve this first distribute the 2, and then distribute the negative sign.
2(b+3)-(7+b)=-7
2b+6-7-b=-7
Combine like terms.
2b+(-b)=b
6+(-7)=-1
b-1=-7
Add 1 on both sides of the equation.
b-1+1=-7+1
b=-6

The graph of function g is a vertical stretch of the graph of function f by a factor of 3. Which equation describes function g?
g(x)=f(x3)
g(x)=3f(x)
g(x)=13f(x)
g(x)=f(3x)
Answer: The correct option is second, i.e., [tex]g(x)=3f(x)[/tex].
Explanation:
A functions g(x) is stretch or compressed of graph of function f(x) is defined by the equation,
[tex]g(x)=kf(x)[/tex]
Where, k is a constant and it shows the compress or stretch factor.
If k>0, then it is a stretch factor and the graph of f(x) is stretched by factor of k.
If k<0, then it is a compress factor and graph of f(x) is compressed by factor k.
Since the graph of g(x) is a vertical stretch of the graph of function f(x) by a factor of 3, therefore,
[tex]g(x)=3f(x)[/tex]
So, the option second is correct.

Oscar and Julie Ashton are celebrating their 15th anniversary by having a reception at a local reception hall. They have budgeted $2,000 for their reception. If the reception hall charges a $90 cleanup fee plus $31 per person, find the greatest number of people that they may invite and still stay within their budget.
To determine the greatest number of people Oscar and Julie can invite within their budget, we can set up an inequality and solve for the variable 'x'. The total cost equation is $90 + $31x ≤ $2,000. Solving this inequality, we find that the greatest number of people they can invite is 61.
Explanation:To determine the greatest number of people that Oscar and Julie may invite and still stay within their budget, we need to set up an inequality based on the given information. Let's denote the number of people they invite as 'x'. The total cost of the reception hall is $90 (cleanup fee) + $31 (per person) * x (number of people). This should be less than or equal to their budget of $2,000. So, the inequality is 90 + 31x ≤ 2000. To solve for 'x', we need to isolate the variable. Subtracting 90 from both sides, we have 31x ≤ 1910. Dividing both sides by 31, we find x ≤ 61.935. Since we can't have a fraction of a person, the greatest number of people they can invite is 61.
