A 64-ounce bottle of apple juice costs $1.35. What is the approximate unit price for this bottle of apple juice?
The approximate unit price for the juice is about $0.50
Step-by-step explanation:
To find the unit price of an item, you must divide the price ($1.35) by how many units the item has (64 ounces). So 64 divided by 1.35 would be 47, or 50 since it's asking for the approximate unit price. Convert it and you have your answer. $0.50. Hope this helps :) I apologize if it's not completely correct

Find the median of the
data. 7,5, 12, 8, 2,9,4
Answer:
7
Step-by-step explanation:
First, put them in numerical order: 2, 4, 5, 7, 8, 9, 12
Then cross out one from each side until you get to the middle
The median of the given data set 7,5, 12, 8, 2,9,4 is 7.
What are the mode and median?Mode is the highest frequency number while the median is the middle value of a data set after writing either increasing or decreasing manner.
For example;
Set { 1,2,2,3,4,5,6} here mode is 2 and median is 3.
Given the data set,
7,5, 12, 8, 2,9,4
If we write it in increasing order then,
2, 4, 5, 7, 8, 9, 12
Now median is middle value so here 7 is in between 3 - 3 from left and right.
Hence "The median of the given data set 7,5, 12, 8, 2,9,4 is 7".

A scatter plot showed a positive correlation for 11 bowlers. As the number of strikes, s, a bowler made in a game increased, the number of points, p, the bowler scores also increased. The equation for the line of best fit for the data is p=25s+40. Estimate the number of strikes made by a bowler with 140 points.
Answer:
s = 4
Step-by-step explanation:
The equation for the line of best fit for the data is p=25s+40.
Where p is no. of points and s is no. fo strikes
We need to find the number of strikes made by a bowler with 140 points.
Put p = 140
p=25s+40
140 = 25s+40
Subtract 40 to both sides,
140-40 = 25s+40-40
100 = 25s
⇒ s = 4
So, there are 4 strikes made by a bowler with 140 points.

Answer:
63 degrees
Step-by-step explanation:
All angles add up to 180
(5x+6) + (4x-6) + (5x-2) = 180
put like terms together
5x+4x+5x + 6-6-2 = 180
14x -2 = 180
add 2 to both sides
14x = 182
divide both sides by 14
x=13
angle G is 5x-2, so if x=13, angle G is 5(13) -2
= 65 -2 = 63 degrees

Tomika heard that the diagonals of a rhombus are perpendicular to each other. Help her test her conjecture. Graph quadrilateral ABCD on a coordinate grid with A(1, 4), B(6, 6), C(4, 1), and D(–1, –1).
a. A rhombus has 4 sides that are equal length. Is ABCD a rhombus? Show how you know.
b. Write the equations of the lines on which the diagonals lie. That is, write the equations of lines AC and BD.
c. Compare the slopes of lines AC and BD. What do you notice?
Answer:
a. The four sides of the quadrilateral ABCD are equal, therefore, ABCD is a rhombus
b. The equation of the diagonal line AC is y = 5 - x
The equation of the diagonal line BD is y = 5 - x
c. The diagonal lines AC and BD of the quadrilateral ABCD are perpendicular to each other
Step-by-step explanation:
The vertices of the given quadrilateral are;
A(1, 4), B(6, 6), C(4, 1) and D(-1, -1)
a. The length, l, of the sides of the given quadrilateral are given as follows;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
The length of side AB, with A = (1, 4) and B = (6, 6) gives;
[tex]l_{AB} = \sqrt{\left (6-4 \right )^{2}+\left (6-1 \right )^{2}} = \sqrt{29}[/tex]
The length of side BC, with B = (6, 6) and C = (4, 1) gives;
[tex]l_{BC} = \sqrt{\left (1-6 \right )^{2}+\left (4-6 \right )^{2}} = \sqrt{29}[/tex]
The length of side CD, with C = (4, 1) and D = (-1, -1) gives;
[tex]l_{CD} = \sqrt{\left (-1-1 \right )^{2}+\left (-1-4 \right )^{2}} = \sqrt{29}[/tex]
The length of side DA, with D = (-1, -1) and A = (1,4) gives;
[tex]l_{DA} = \sqrt{\left (4-(-1) \right )^{2}+\left (1-(-1) \right )^{2}} = \sqrt{29}[/tex]
Therefore, each of the lengths of the sides of the quadrilateral ABCD are equal to √(29), and the quadrilateral ABCD is a rhombus
b. The diagonals are AC and BD
The slope, m, of AC is given by the formula for the slope of a straight line as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore;
[tex]Slope, \, m_{AC} =\dfrac{1-4}{4-1} = -1[/tex]
The equation of the diagonal AC in point and slope form is given as follows;
y - 4 = -1×(x - 1)
y = -x + 1 + 4
The equation of the diagonal AC is y = 5 - x
[tex]Slope, \, m_{BD} =\dfrac{-1-6}{-1-6} = 1[/tex]
The equation of the diagonal BD in point and slope form is given as follows;
y - 6 = 1×(x - 6)
y = x - 6 + 6 = x
The equation of the diagonal BD is y = x
c. Comparing the lines AC and BD with equations, y = 5 - x and y = x, which are straight line equations of the form y = m·x + c, where m = the slope and c = the x intercept, we have;
The slope m for the diagonal AC = -1 and the slope m for the diagonal BD = 1, therefore, the slopes are opposite signs
The point of intersection of the two diagonals is given as follows;
5 - x = x
∴ x = 5/2 = 2.5
y = x = 2.5
The lines intersect at (2.5, 2.5), given that the slopes, m₁ = -1 and m₂ = 1 of the diagonals lines satisfy the condition for perpendicular lines m₁ = -1/m₂, therefore, the diagonals are perpendicular.

Which equation describes a line with a slope of -1/2 that contains the point (-5, 2)?
A. x + 2y = 1
B. x - 2y = -1
C. x - 2y = 1
D. x + 2y = -1
Answer:
The equation x + 2y = -1 describes a line with a slope of -1/2 that contains the point (-5, 2) ⇒ D
Step-by-step explanation:
The slope of the linear equation of the form ax + by = c is m = [tex]\frac{-a}{b}[/tex] , where a and b are integersLet us use this rule to solve the question
The slope of the line is [tex]-\frac{1}{2}[/tex] and the line contains the point (-5, 2)
We want to find which equation has the same slope and contains the point
A.
∵ x + 2y = 1
∴ a = 1 and b = 2
→ Use the rule above to find m
∴ m = [tex]\frac{-1}{2}[/tex]
∴ The line has the same slope
→ Let us find if the line contains the point (-5, 2), by substituting x by -5
and y by 2 in the left side of the equation if the answer equals
the right side, then the line contains it
∵ L.S = -5 + 2(2) = -5 + 4 = -1
∵ R.S = 1
∴ L.S ≠ R.S
∴ The line does not contain the point (-5, 2)
B.
∵ x - 2y = -1
∴ a = 1 and b = -2
→ Use the rule above to find m
∴ m = [tex]\frac{-1}{-2}[/tex] = [tex]\frac{1}{2}[/tex]
∴ The line does not have the same slope
C.
∵ x - 2y = 1
∴ a = 1 and b = -2
→ Use the rule above to find m
∴ m = [tex]\frac{-1}{-2}[/tex] = [tex]\frac{1}{2}[/tex]
∴ The line does not have the same slope
D.
∵ x + 2y = -1
∴ a = 1 and b = 2
→ Use the rule above to find m
∴ m = [tex]\frac{-1}{2}[/tex]
∴ The line has the same slope
→ Substitute x by -5 and y by 2 in the left side
∵ L.S = -5 + 2(2) = -5 + 4 = -1
∵ R.S = -1
∴ L.S = R.S
∴ The line contains the point (-5, 2)
The equation x + 2y = -1 describes a line with a slope of -1/2 that contains the point (-5, 2)

5) The sides of a quadrilateral are in the ratio 1:2:3:6. The perimeter is 138 cm.
Answer:
The first side is 11.5cm, the second is 11.5cm×2 = 23cm, the third is 11.5cm × 3 = 34.5cm,
and the fourth side is 11.5cm × 6 = 69cm.
Step-by-step explanation:
A quadrilateral is a 4 sided shape, while perimeter is the addition of all the sides of the quadrilateral. Since the sides of the quadrilateral is not stade, assume the sides of the quadrilateral is x, therefore 1:2:3:6 = x:2x:3x:6x. The total ratio is x+2x+3x+6x=12x, therefore 12x= 138 , x = 11.5cm, Therefore the first side is 11.5cm, the second is 11.5cm×2 = 23cm, the third is 11.5cm × 3 = 34.5cm, and the fourth is 11.5cm × 6 = 69cm.

Answer:
r = 0.1
Step-by-step explanation:
Constant proportionality or slope(rate of change) is found by Y divided by X.
1.4(y) ÷ 14(x) = 0.1(slope)
1.6(y) ÷ 16(x) = 0.1(slope)
2.1(y) ÷ 21(x) = 0.1(slope)
Check Work:
14 x 0.1 = 1.4
16 x 0.1 = 1.6
21 x 0.1 = 2.1
Answer:
1/10.
Step-by-step explanation:
The proportionality equation is given to you: [tex]y = rx[/tex]
Next, plug in the given [tex]x[/tex] and [tex]y[/tex] variables into the equation:
When: [tex]x = 14[/tex] & [tex]y = 1.4[/tex]
[tex]1.4 = r(14)\\1.4 = 14r\\(1.4)/14 = (14r)/14\\1.4/14 = r\\r = 0.1[/tex]
When: [tex]x = 16[/tex] & [tex]y = 1.6[/tex]
[tex]1.6 = r(16)\\1.6 = 16r\\(1.6)/16 = (16r)/16\\r = 1.6/16\\r = 0.1[/tex]
When: [tex]x = 21[/tex] & [tex]y = 2.1[/tex]
[tex]2.1 = r(21)\\[/tex]
[tex]21r = 2.1\\(21r)/21 = (2.1)/21\\r = 2.1/21\\r = 0.1[/tex]
r = 0.1 in all of the given, ∴ 0.1 is your answer. Change the decimal into a fraction:
0.1 = 1/10
1/10 is your answer.

HELP, I have to turn this in tomorrow ... is this correct??
Answer: yes
Step-by-step explanation:
A sports team is ordering a new banner to hang over the entrance of their stadium. The banner will be a right triangle where one leg is 33 feet and the other leg is 56 feet. All three edges of the banner will be lined with a ribbon that costs $0.50 per foot. How much will the ribbon cost?
Answer:
The ribbon cost is $77
Step-by-step explanation:
Firstly, we need to get the 3rd side of the triangle
This represents the hypotenuse since we have 2 legs, we need the side connecting the legs
To get this, we use Pythagoras’ theorem
This states that the square of the hypotenuse equals the sum of the squares of the two other sides
Let the hypotenuse be marked x
Thus;
x^2 = 56^2 + 33^2
x^2 = 3136 + 1089
x^2 = 4225
x = square root of 4225
x = 65 feet
So the length of all the sides will be;
56 + 33 + 65 = 154 feet
So the cost of the ribbon will be;
154 feet. * 0.5
= $77
