Step-by-step explanation:
A drink recipe calls for prune juice and carrot juice. This equation represents the proportional relationship between the number of quarts of prune juice (p) and carrot juice (c) in the recipe. 4p = 12c. Enter the number of quarts of carrot juice used for 1 quart of prune juice.
Answers
Answer:
The number of quarts of carrot juice used is approximately 0.3333.
Step-by-step explanation:
The proportional relationship between the quarts of prune juice (p) and carrot juice (c) in the recipe is given as;
4p = 12c
Thus for 1 quart of prune juice, the quarts of carrot juice required can be determined by;
i.e p = 1
So that,
4 x 1 = 12c
4 = 12c
c = [tex]\frac{4}{12}[/tex]
= [tex]\frac{1}{3}[/tex]
= 0.3333
The number of quarts of carrot juice used is approximately 0.3333.

Answers
Answer:
C) choosing a blue, green or yellow marble.
Step-by-step explanation:
The Complement of choosing a red marble means choosing any other marble that isn't red.
From the question , it was said that there were a blue , green, yellow and red marble.
So the Complement of choosing a red marble will be choosing any other marble apart from the red so ,that will be choosing a blue yellow or green marble.

A line with a slope of -7 passes through the points (-8, 7) and (-7, k). What is the value of
K?
Answers
Answer:
k = 0
Step-by-step explanation:
On the graph, the second point would be at (-7,0)
Answer:
k = 0
Step-by-step explanation:
We can find the answer to this question by using the slope equation:
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's define some variables:
[tex]\frac{k - 7}{-7-(-8)} = \frac{k-7}{1} = k- 7[/tex]
We know the slope is -7 so we can put k-7 equal to it and solve
[tex]k-7 = -7\\k = 0[/tex]
We find that k is equal to 0.
I hope this helps!!

Identify the graphed linear equation?
Answers
Answer:
C
Step-by-step explanation:
The first thing I notice is the slope, which is going down, which means this is for sure a negative slope. So any slopes that just include 5 is now crossed off. And since the formula goes like y=mx+b, I believe the answer would be C, because it actually follows the formula as it should. If I'm wrong, pick D for sure.

Last year 858 people attended the Middleton County Fair. This year 1,635 people attended. What was the percent increase from last year to this year? (Round to the nearest percent)
Answers
Answer:
91%
Step-by-step explanation:
The first step is to calculate the increase
= 1635-858
= 777
Therefore the percent increase can be calculated as follows
= 777/858 × 100
= 0.905× 100
= 90.5 %
= 91%
Hence the percentage increase is 91%

Task: Nonpermissible Values for Rational Expressions [30 points] Write a rational expression that has the nonpermissible values x=0 and x=17. Explain your reasoning using complete sentences.
Answers
Answer:
A rational expression that has the nonpermissible values [tex]x = 0[/tex] and [tex]x = 17[/tex] is [tex]f(x) = \frac{4}{x\cdot (x-17)}[/tex].
Step-by-step explanation:
A rational expression has a nonpermissible value when for a given value of [tex]x[/tex], the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
[tex]f(x) = \frac{p(x)}{q(x)}[/tex] (1)
Then, the factorized form of [tex]q(x)[/tex] must be:
[tex]q(x) = x\cdot (x-17)[/tex] (2)
If we know that [tex]p(x) = 4[/tex], then the rational expression is:
[tex]f(x) = \frac{4}{x\cdot (x-17)}[/tex] (3)
A rational expression that has the nonpermissible values [tex]x = 0[/tex] and [tex]x = 17[/tex] is [tex]f(x) = \frac{4}{x\cdot (x-17)}[/tex].

Mrs. Olive used 1 2/5 quarts of syrup and 5 3/10 quarts of water to make lemonade. How many quarts of lemonade did she make? * A. 6 1/2 B. 6 7/10 C. 7 1/2 D. 8
Answers
Answer:
B. 6 7/10
Step-by-step explanation:
We solve the above y by carrying out addition.
The quarts of Lemonade she made is calculated as:
1 2/5 quarts of syrup + 5 3/10 quarts of water
= 1 + 5 + (2/5 + 3/10)
Lowest common denominator = 10
= 6 ( 4 + 3/10)
= 6 7/10 quarts of Lemonade
Mrs Olive made 6 7/10 quarts of Lemonade
For a soccer practice, the coach set up four cones, labeled W, X, Y, and Z, to mark the edges of the rectangular field. Suppose the field is drawn on a coordinate plane, where the x- and y-values represent the position, in yards, from the center of the field, which is located at (0, 0). The location of the cones are as follows. Cone W is located at (-38, -53). Cone X is located at (-38, 53). Cone Y is located at (38, 53). Cone Z is located at (38, -53). What is the perimeter of the field? A. 364 yards B. 8,056 yards C. 182 yards D. 38 yards
Answers
Answer:
A. 364 yards
Step-by-step explanation:
The distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)[/tex] on the coordinate plane is given as:
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The cone W, X, Y and Z form a rectangle.
The perimeter for the rectangle = 2(length + breadth)
[tex]Length=|WX|=\sqrt{(-38-(-38))^2+(53-(-53))^2}=106 \\\\Breadth=|XY|=\sqrt{(38-(-38))^2+(53-53)^2}=76[/tex]
Perimeter = 2(length + breadth) = 2(106 + 76) = 364 yards

Can someone explain Slope to me? I literally have no idea what is from my teacher or from Aleks. I don't get what y1 and y2 are and i don't get what rise or run is. I have no idea how to get slope (brainliest for whoever explains a function too)
Answers
Yeah, I know Alex sucks. SO slope is the change in Y over x. So to find slope for ex. is lets use points (8,4) and (6,5) the equation to find slope is Y2-Y1 over X2-X1 or Y2-Y1 / X2-X1 and that basically the y's on the points you have. In this case it will be 4 and 5 since y always comes second or after the x. What I like to do is this X1(8), Y1(4) and X2(6), Y2(5). After you have that set up you just put them in the equation it will be 5-4/6-8 which is -1/2 use calculator. So Y is the y-axis and X is the x-axis.
Function is when every input(x) has only one output(y) . For example if we have the table
X,1 , 4 , 5, 9, 10 this is not a function because the -3 has both 9 and 10 for an output.
Y,2, 6 ,6, -3 , -3
A function will look more like this
1 2 3 4 5 6
2 4 6 8 10 12 every output has only one input
I recommend to watch Brian McLogan on youtu he can really help. Just search anything then his name. Or even Function then his name he explains it really well.
