Answer: D. n + q = 20
5n + 25q = 300
Step-by-step explanation:
Let n represent the number of nickels that you have.
Let q represent the number of quarters that you have.
Suppose you have 20 coins. It means that
n + q = 20
The total value of the coins is $3. The value of a quarter is $0.25 and the value if a nickel is $0.05. Therefore, the equation would be
0.05n + 0.25q = 3
Multiplying both sides of the equation by 100, it becomes
5n + 25q = 300
The correct option is
D. n + q = 20
5n + 25q = 300

The perimeter of a rectangle is 34 units its width is 6.5 Units
Write an equation to determine the length(l) of the rectangle.
Answer: Length=10.5
Step-by-step explanation: P=34 and W=6.5. This can also be known as Perimeter=W+L+W+L=2(W+L). In this case, it would be 34= 2(6.5 +L). 34=13+2L.(The 2L's are crossed out now because they cancel both out)
-2L -2L (There is a line going down at the equal sign.
34+-2L=13 Subtract 34 from both sides and cancel the two 34's out)
-34 -34
-2L=-21 (Divide both sides by -2) (Cancel out the -2's)
/-2 /-2
L = 10.5

What is an
equation of the line that passes through the points (-3,8) and (4,1)?
Answer: y= -1x + 5
Step-by-step explanation:
(-3,8) ( 4,1)
8-1= 7
-3-4 = -7
7/-7 = -1 so the slope is -1 so we will use the formula y=mx+b to find the y-intercept
8= -1(-3) + b
8= 3 + b
-3 -3
b= 5 so the y intercept is 5 now we will write the equation like this y= -1x + 5

How to find the function which was used to make graph?A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that the function crosses x axis at some point then for some polynomial functions, we have those as roots of the polynomial.
Hence, the equation of this graph would be (x − 5)^2 = -8(y + 4).
So option D is correct.

The last step is to add 12 + -12 which equals 0.
The given bar graph shows the percentage of U.S. women in the labor force from 1960 through 2010. The function f left parenthesis x right parenthesis equals 3.5 square root of x plus 38 models the percentage of U.S. women in the labor force, f left parenthesis x right parenthesis , x years after 1960. Use this formula to solve the following questions.
US women in Labor ForceAccording to the model above, approximately what percentage of women will be a part of the work force in 1996? Does the given bar graph verify this result? Explain why or why not. Use complete sentences and proper labels to answer.
Answer:
59% of women will be a part of the work force in 1996
According to the bars, the percentage was in the range of 57.5 - 60.2. This verify the previous result.
Step-by-step explanation:
In the figure attached, the bar graph is shown.
f(x) = 3.5√x + 38
where f(x) models the percentage of U.S. women in the labor force x years after 1960. In 1996, x = 1996 - 1960 = 36. Replacing it into the equation:
f(36) = 3.5√36 + 38 = 59%

The volume of the trapezoidal prism comes to be 312 cubic units.
What is the volume of a prism?The volume of a prism is the product of the base area and its height.
So, the volume of the given prism = area of trapezoidal base * height
Area of the trapezoidal base = 0.5 * (sum of parallel sides) * distance between parallel sides.
Area of the trapezoidal base =0.5 * (8+5) * 4
Area of the trapezoidal base =26 square unit
So, the volume of the given prism = 26*12 = 312 cubic units.
Hence, the volume of the trapezoidal prism comes to be 312 cubic units.

D.The difference between the mean cost to treat dogs at No Ruff Stuff Animal
Hospital and the mean cost to treat cots at No Ruff Stuff Animal Hospital is

Answer:
C. 5 times the MAD
Step-by-step explanation:
The difference between the mean cost to treat dogs at No Ruff Stuff Animal Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is about 5 times the MAD. This is a large difference.
The correct option is C.
What is the mean?In mathematics and statistics, the term "mean" refers to the average of a set of variables. There are various ways to determine the mean, including geometric means, harmonic means, and simple arithmetic means (putting the numbers together and dividing the result by the number of observations).
Given:
The mean cost to treat dogs at No Ruff Stuff Animal Hospital is $224.65.
And MAD = $20.52
The mean cost to treat cats at No Ruff Stuff Animal Hospital is $124.84.
And MAD = 19.75.
The difference between the mean cost to treat dogs at No Ruff Stuff Animal
Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is,
= 224.65 - 124.84.
= 99.81
= 5 x 19.75
Therefore, the difference is 5 times MAD.
