Charity donated by Tillman = $3540

Number of employees who donated = 118

Contribution of Tillman = 40%

Let the average contribution of employees be = x

Then the amount contributed by employees = 118x

Then contribution of Tillman = [tex]\frac{40}{100}\times118x[/tex]

As Tillman donated 3540 , then

[tex]3540=\frac{40}{100}\times118x[/tex]

[tex]3540=47.20x[/tex]

[tex]x=75[/tex]

Hence, average contribution by each employee is $75.

Option C is correct.

Answer:

$75

Tillman's donation = .40(total employees' donations)

$3540 = .40x

x = 8850

8850

118

= $75 for each employeeep explanation:

$75

Tillman's donation = .40(total employees' donations)

$3540 = .40x

x = 8850

8850

118

= $75 for each employee

if x can be 2-5 and y can be 1-6, c=3(5)+4(6)

which would turn out to be c=39

The maximum value of C will be equal to 39.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given constraints are:-

x  ≥   2

x  ≤   5

y  ≥   1

y  ≤  6

Here maximum value of x = 5 and for y = 6

Putting the maximum values of x and y to calculate the maximum value of C.

C  =  3x  +  4y

C  = ( 3 x 5 )  +  (  4  x  6 )

C  =  15  +  24

C   =  39

Therefore the maximum value of C will be equal to 39.

If you borrowed $100, then your monthly payment is $2.44

If you borrowed $200, then your monthly payment is 2*2.44 = 4.88

etc etc

We can set up a proportion

2.44/100 = x/13300

to figure out the monthly payment x. Cross multiply and solve for x

2.44*13300 = 100*x

100x = 2.44*13300

100x = 32452

x = 32452/100

x = 324.52

So the monthly payment is $324.52

An alternative way to get this monthly payment is to apply 2.44% to 13300, which is another way to view the phrase  "monthly payment per $100 is 2.44"

------------------

There are 48 months in 4 years (start with 12 mon = 1 yr, then multiply both sides by 4) so we multiply 48 by the monthly payment to get the result 48*324.52 = 15,576.96. This is the total amount you have to pay back which is the principal plus interest.

Subtract off the principal (amount borrowed) to find the interest or finance charge: 15,576.96 - 13,300 = 2,276.96

Answer: Choice B

The finance charge on $13,300 financed at 7.9 percent for 4 years is $12,975.48.

To calculate the finance charge, we need to first find the total amount financed. We can do this by multiplying $13,300 by the monthly payment per $100, which is $2.44. $13,300 divided by 100 is 133, so we multiply 133 by 2.44 to get $324.52. Now, we can calculate the finance charge by subtracting the total amount financed from the original loan amount. $13,300 minus $324.52 is $12,975.48. Therefore, the finance charge is $12,975.48.

Final answer:

To create an alloy with 4.9 lb of zinc based on the nickel to zinc ratio of 2:7, about 1.4 pounds of nickel is required.

Explanation:

To determine how many pounds of nickel have to be used to create an alloy that contains 4.9 lb of zinc, we must first understand the given ratio of nickel to zinc to copper in the alloy, which is 2:7:9. Since zinc's ratio is 7 and we have 4.9 lb of it, we can calculate the amount of nickel by setting up a proportion.

We use the proportion 2/7 = x/4.9, where x represents the pounds of nickel. By cross-multiplying and solving for x, we get x = (2 * 4.9) / 7, which simplifies to x = 9.8 / 7. This gives us the result x ≈ 1.4 lb.

Therefore, to create an alloy with 4.9 lb of zinc, approximately 1.4 pounds of nickel are needed.

f(x) - n - shift a graph n units down

f(x + n) - shift a graph n units left

f(x - n) - shift a graph n units right

-------------------------------------

when rounded to the tenths place it would be 9.3

Let us check the slope of y-intercepts of the given lines in the graph first.

The y-intercept of above line is 1 and slope of

Rise/run = 2/1 (Moving 2 units up and 1 unit right).

So, the equation should be

y=2x+1

Y-intercept of second line is -2 and slope is

Rise/run = -1/1 (Moving 1 unit down and 1 unit right).

So, the equation should be

y=-x-2.

Now, we need to check the shaded portion for inequality signs.

We have both lines dotted.

So, the inequality signs would be just < or >.

For y=2x+1 line : Shading is on the left side.

On the left side of the line y=2x+1, the y-values are greater than on right side.

Therefore, we got first inequality y>2x+1

For y=-x-2 line : Shading is on the down of the line.

On the down of the line y=-x-2, the y-values are less than up side of the line.

Therefore, second inequality would be

y<-x-2 or y+x<-2

Therfore, correct option is first option y>2x+1 and y+x<-2.

You could buy 8 lemons for 60 cents.

Since you are solving for a, you want to have a on one side of the equation and the other terms on another side of the equation. It would be easiest to have all the terms with a on the left side of the equation, so that is what we will do.

Subtract 9a from both sides to get a on the left side of the equation.

5 + 5a = -5

Subtract 5 from both sides of the equation to isolate the term with a.

5a = -10

Divide both sides of the equation by 5 to solve for a.

a = -2

The result to the equation is a = -2.

To break for a in the equation 5 + 14a = 9a - 5, we can start by simplifying both sides of the equation.

Adding 5 to both sides

5 + 14a + 5 = 9a - 5 + 5

10 + 14a = 9a

Next, we can insulate the variable a by abating 9a from both sides

14a - 9a + 10 = 9a - 9a

5a + 10 = 0

To break for a, we'll abate 10 from both sides

5a + 10 - 10 = 0 - 10

5a = -10

Eventually, we divide both sides by 5 to break for a

5a/ 5 = -10/ 5

a = -2

Thus, the result to the equation is a = -2.

If f(x) varies directly with  [tex]x^2[/tex]

If f(x) varies directly with x then we use equation f(x) = kx

where k is the constant of proportionality

So equation becomes [tex]f(x) = kx^2[/tex]

We use the information and find out k

f(x)= 10

[tex]f(x) = kx^2[/tex]

[tex]10= kx^2[/tex]

[tex]k = \frac{10}{x^2}[/tex]

now we use the value of k and find the value of f(x) when x=3

[tex]f(x) = \frac{10}{x^2}*x^2[/tex]

f(x) = 10

The value of f(x) = 10 when x= 3

The value of f(x) when x=3 is 90.

If f(x) varies directly with x2 and is given that f(x)=10 when x=1 (since 1 squared is 1), we can express the direct variation as f(x) = k × x2, where k is the constant of variation. To find the value of k, we use the information that f(1)=10. Thus, 10 = k × 12, which means k=10.

Now that we know k=10, we can find f(x) when x=3. We substitute x with 3 in the equation f(x) = 10 × x2, yielding f(3) = 10 × 32 = 10 × 9 = 90. Therefore, the value of f(x) when x=3 is 90.
