Growing up, I never got enough of my favorite side dishes. I even conducted a - survey to prove to my family that they should make more mashed potatoes. In my survey, I found that the ratio of people who prefer mashed potatoes to sweet potato casserole was 7:2. I 18 people preferred sweet potato casserole, how many preferred mashed potatoes? .S
Answer:
63 people prefer mashed potatos
Step-by-step explanation:
18 divided by 2 is 9
7 multiplied by 9 is 63

A certain ride at an amusement park requires that children be at least 50 inches tall but no more that 65 inches tall. Which of the following absolute values best represents this restriction, where h represents height?
Answer:
|h-57.5| less than or equal to 7.5
Step-by-step explanation:
Since the question states that a child must be 50 and 65 inches, plug in values that are within this range and determine which answer choice gives a TRUE relationship. Choose 60 for h.

Explain how you can use multiplication to solve a division problem.
Answer:Inverse operation
Step-by-step explanation: an example is 5 x 5. That equals 25 so take 5 and divide that by 5. Inverse operation is important.

What’s the domain and range of this graph?
Given:
The graph of a downward parabola.
To find:
The domain and range of the graph.
Solution:
Domain is the set of x-values or input values and range is the set of y-values or output values.
The graph represents a downward parabola and domain of a downward parabola is always the set of real numbers because they are defined for all real values of x.
Domain = R
Domain = (-∞,∞)
The maximum point of a downward parabola is the vertex. The range of the downward parabola is always the set of all real number which are less than or equal to the y-coordinate of the vertex.
From the graph it is clear that the vertex of the parabola is at point (5,-4). So, value of function cannot be greater than -4.
Range = All real numbers less than or equal to -4.
Range = (-∞,-4]
Therefore, the domain of the graph is (-∞,∞) and the range of the graph is (-∞,-4].

Answer/Step-by-step explanation:
✔️Find k:
Reference angle = 60°
Hypotenuse = k
Opposite = 9
Therefore, using trigonometric ratio, we have:
[tex] sin(60) = \frac{9}{k} [/tex]
Multiply both sides by k
[tex] k*sin(60) = 9 [/tex]
Divide both sides by sin(60)
[tex] k = \frac{9}{sin(60)} [/tex]
[tex] k = \frac{9}{\frac{\sqrt{3}}{2}} [/tex]
[tex] k = 9*\frac{2}{\sqrt{3}} [/tex]
[tex] k = \frac{18}{\sqrt{3}} [/tex]
Rationalize
[tex] k = \frac{18*\sqrt{3}}{\sqrt{3}*\sqrt{3}} [/tex]
[tex] k = \frac{18\sqrt{3}}{3} [/tex]
[tex] k = 6\sqrt{3} [/tex]
✔️Find f:
Reference angle = 60°
Opposite = 9
Adjacent = f
Therefore, using trigonometric ratio, we have:
[tex] tan(60) = \frac{9}{f} [/tex]
Multiply both sides by f
[tex] f*tan(60) = 9 [/tex]
Divide both sides by tan(60)
[tex] f = \frac{9}{tan(60)} [/tex]
[tex] k = \frac{9}{\sqrt{3}} [/tex]
Rationalize
[tex] k = \frac{9*\sqrt{3}}{\sqrt{3}*\sqrt{3}} [/tex]
[tex] k = \frac{9\sqrt{3}}{3} [/tex]
[tex] k = 3\sqrt{3} [/tex]

A line passes through point A(12,18). A second point on the line has an x-value that is 125% of the x-value of point A and a y-value that is 75% of the y-value of point A. Use point A to write an equation of the line in point-slope form.
PLEASE! PUT THIS IN POINT SLOPE FORM!
Answer:
y - 18 = -1.5(x - 12)
Step-by-step explanation:
A = (12, 18)
B=(1.25(12), 0.75(18)) = (15, 13.5)
Find slope: m = (13.5-18)/(15-12) = (-4.5)/3 = -1.5
Point slope form: y - y1 = m(x - x1)
Using point A as (x1, y1)
y - 18 = -1.5(x - 12)
which expression is equivalent to 3(7v)

Max delivers 8,520 pieces of mail in one year. If he delivers the same number of pieces of mail each month, about how many pieces of mail does he deliver in 2 months? Solve the problem and explain the steps you took to solve.
Answer:
Because there are 12 months in a year the ratio of the number of pieces of mail Max delivers in 12 months can be written as: 852012 or 7101 (720 pieces of mail per month).
Answer:
He would deliver 1420 mails in 2 month's
Step-by-step explanation:
First, I divided 8,520 by 12 because 12 month's in one 1 year
Then, I get 710, that is the amount he delivers each month
Lastly, I multiply 710 by 2 because that is the amount for 2 month's and it equals 1,420 so, the answer is 1,420 :)

25x^3+5x^2+30x+6=0 solve
Answer:
x = -1/5, x = i sqrt(30)/5, x = -i sqrt(30)/5
Step-by-step explanation:
25x^3 + 5x^2 + 30x + 6 = 0
5x^2(5x + 1) + 6(5x + 1) = 0
(5x + 1)(5x^2 + 6) = 0
5x + 1 = 0
5x = -1
x = -1/5
5x^2 + 6 = 0
5x^2 = -6
x^2 = -6/5
x = +/- sqrt(-6/5)
x = +/- i * sqrt(30)/5
x = i sqrt(30)/5 or x = -i sqrt(30)/5

A certain student has taken 124 credit hours so far in college. The student took the same number of credit hours in each fall semester and the same number of credit hours in each spring semester. The equation 15x + 16y 124 represents this situation, where x is the number of fall semesters and y is the number of spring semesters in which the student has taken classes. How many more credit hours did the student take in each spring semester than in each fall semester?

graph the equation below using slope intercept form y=-3x+8
Answer:
here is a graph from Desmos
Step-by-step explanation:
What is the slope of the line shown in the graph?
A 3/2
B) 2/3
C) -3/4
D) -2/3
Answer:
D.
Step-by-step explanation:
y-intercept is (0, 3)
x-intercept is (4.5, 0)
formula to find the slope from two points is
[tex]slope = m = \frac{y2 - y1}{x2 - x1} = \frac{y1 - y2}{x1 - x2} \\ [/tex]
then the slope of the line that crosses (0, 3) & (4.5, 0) is
[tex]m = \frac{3 - 0}{0 - 4.5} = \frac{3}{ - 4.5} = - \frac{3}{ \frac{9}{2} } = - \frac{2}{3} [/tex]
