Answer:
A', is the set of all elements in the given universal set U .
But the union of sets is an operation performed on two sets, say A and B, which results in a set that has all elements belonging either to set A and set B or both. The operand of union of set is given by '∪'. You can see, U is also a set which collectively shows all the elements of A, B and of itself.

Target is advertising a Back to School sale on pens. A pack of 30 sells for $8.90, whereas a 15-pack of me same brand costs $4.39. Which is the better buy? How do you know?
Answer: Well you don't really need to do math. You have to think half of 30 is 15. So then you would multiply 4.39 times 2 and you get 8.78. So the 15 pack is a better deal.

At the sewing store, Bridgette bought a bag of mixed buttons. The bag included 90 buttons, of which 20% were large. How many large buttons did Bridgette get?
Answer:
18 large buttons
Step-by-step explanation:
Given that :
A bag of mixed button was purchased ;
Total number of buttons in the bag = 90
Percentage number of large buttons on bag = 20%
Number of large buttons in bag :
(Percentage Number of large buttons * total number of buttons)
= 20% * 90
= 0.2 * 90
= 18
Hence, there are 18 large buttons in the bag.
What is the slope of the line that passes through the points (2, 0) and (32, -5)? Write your answer in simplest form.
Answer:
-1/6
Step-by-step explanation:
The slope of the line passing through the given points (2, 0) and (32, -5) is [tex]\frac{-1}{6}[/tex]
Given the following points:
Points on the x-axis = (2, 32)Points on the y-axis = (0, -5)To find the slope of the line passing through the given points (2, 0) and (32, -5):
The slope of a line refers to the gradient of a line and it is typically used to describe both the direction and steepness of an equation of a straight line.
Mathematically, the slope of a line is given by the following formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substituting the given points into the formula, we have;
[tex]Slope. \;m = \frac{-5 \;- \;0}{32\; - \;2}\\\\Slope. \;m = \frac{-5}{30}\\\\Slope. \;m = \frac{-1}{6}[/tex]

Manny's cleaning supply store receives a mixture of 80% detergent and 20% water in 15-gallon buckets. Manny would like a mixture of 60% detergent and 40% water in 5-gallon buckets. To make this, he combines some 80/20 mixture with some pure water in each 5-gallon bucket. How many gallons of pure water does Manny add to each 5-gallon bucket? Express your answer as a decimal to the nearest hundredth.
Answer:
1.25 gallons of pure water
Step-by-step explanation:
Manny's cleaning supply store receives a mixture of 80% detergent and 20% water in 15-gallon buckets.
0.80 d + 0.20w = 15 gallon
Manny would like a mixture of 60% detergent and 40% water in 5-gallon buckets.
0.60d + 0.40w = 5 gallon
0.80 d + 0.20w = 15 ....... Equation 1
0.60d + 0.40w = 5 ......….. Equation 2
Using elimination method
Multiply Equation 1 with 0.60
Multiply Equation 2 with 0.80
We eliminate d
0.80 d + 0.20w = 15 × 0.6
0.60d + 0.40w = 5 × 0.8
=
0.48d + 1.2w = 9....... Equation 4
0.48d + 3.2w = 4..... Equation 5
Subtract Equation 5 from 4
= - 2.0w = -5
w = -5/-2
w = 2.5 gallons.
Hence: 2.5 gallons/2
= 1.25 gallons.
Therefore, Manny adds 1.25 gallons of pure water.

The equation of the graphed line, in slope-intercept form, is: y = -3x + 7.
How to Find the Equation of a Line in Slope-intercept Form?To find the equation of the line that is given above, we need to find the slope of the line (m) and the y-intercept (b), then substitute the values into y = mx + b.
Find the slope:
Slope of a line (m) = change in y / change in x = rise/run
The line declines, so, the value of the slope would be negative.
Rise (change in y) = 3 units
Run (change in x) = 1 unit
Slope (m) = - (3 units/1 unit)
Slope (m) = -3
The y-intercept (b) would be the point where the line cuts the y-axis, which is: 7.
Y-intercept (b) = 7
Write the equation by substituting b = 7 and m = -3 into y = mx + b:
y = -3x + 7.
Thus, the equation, in slope-intercept form, is: y = -3x + 7.

which table has a constant of proportionality between Y and X of 1/5?
Answer:
B
Step-by-step explanation:
From the table B has a constant of proportionality between y and x of 1/5.
We need to find which table has a constant of proportionality between y and x of 1/5.
What is constant of proportionality?Constant of proportionality is the constant value of the ratio between two proportional quantities.
The equation for direct proportionality is y = kx, which shows as x increases, y also increases at the same rate.
Now, k=y/x
From table A:
k=4/5 ÷ 2
=2/5
k=14/5 ÷ 7
=2/5
k=24/5 ÷ 12
=2/5
From table B:
k=8/5 ÷ 8
=1/5
k=9/5 ÷ 9
=1/5
k=2/10 =1/5
From table C:
k=16/5 ÷ 3
=16/15
k=26/5 ÷ 5
=26/25
k=36/5 ÷ 7
=36/35
Therefore, from the table B has a constant of proportionality between y and x of 1/5.
