Brand 6
1) In this problem, we need to find the unit rate. So let's do it and then compare for both brands
2) Brand A
[tex]\begin{gathered} 20oz----2.5 \\ 1oz-----x \\ 20x=2.5 \\ \frac{20x}{20}=\frac{2.5}{20} \\ x=\$0.125 \end{gathered}[/tex]So for Brand A, 1 oz is approximately 13 cents ( rounding up to the nearest hundredth)
3) Brand 6
We can write out another proportion:
[tex]\begin{gathered} 32oz----3.25 \\ 1oz----y \\ 32y=3.25 \\ \frac{32y}{32}=\frac{3.25}{32} \\ y=\$0.101 \end{gathered}[/tex]So brand 6, 1 oz is approximately 10 cents.
Micah has an electricity plan where he is charged a monthly fixed rate of $3.18 and a usage fee of $0.14 per kilowatt-hour. In the equation below, x represents the amount of electricity he used, and y represents the amount Micah was charged for electricity. y = $0.14x + $3.18 If Micah was charged $143.18 for electricity last month, how much electricity did he use? A. 140 kilowatt-hours B. 45 kilowatt-hours C. 1,023 kilowatt-hours D. 1,000 kilowatt-hours Reset Submit
Answer:
D. 1,000 kilowatt-hours
Step-by-step explanation:
Given:
[tex]y=0.14x+3.18[/tex]
If Micah was charged $143.18, then:
[tex]143.18=0.14x+3.18[/tex]
First, subtract 3.18 from both sides:
[tex]140.00=0.14x[/tex]
Then, divide both sides by 0.14:
[tex]1000=x[/tex]
2. The volume of a 3-D shape is 13 cubic feet. The shape is scaled up and the new volume is 832 cubic
feet. What was the scale factor?
Scale factor of given equation is 64 : 1
What is scale factor ?Scale Factor is used to scale the shape in various dimensions. In Geometry you will learn about different geometric shapes in 2D and 3D. A scale factor is a measure of similar figures that look the same but have different scales or measurements. Suppose two circles are similar but may have different radii. The scale factor indicates how much larger or smaller the figure is than the original figure. Scale allows you to scale the original shape up or down and draw it. The amount by which a shape is magnified or shrunk is called the scale factor. Used when you need to increase the size of 2D shapes such as circles, triangles, squares, and rectangles. Magnification is also well understood from the basic theorem of proportionality.Calculationinitial volume = 13 cubic feet
final volume = 832 cubic feet
scale factor = 832 / 13
= 64 : 1

Answer:
x = 23
y = 119
Step-by-step explanation:
Line m is parallel to line n and the angle given as 61 and the angle that is represented with 4x - 31 are alternate angles and have equal measurement.
We can write the following equation based on this information:
4x - 31 = 61 add 31 to both sides
4x = 92 divide both sides by 4
x = 23
now onto y,
the angle represented with y and the angle that is represented with 4x - 31 are supplementary and their measures add up to 180:
4x - 31 + y = 180 replace x with 23
4*23 - 31 + y = 180
92 - 31 + y = 180 subtract like terms
61 + y = 180 subtract 61 from both sides
y = 119
1/16*1/8 in exponential form
The exponential form of 1/6 × 1/ 8 = 1/32 = 3.125 × [tex]10^{-5}[/tex]
The given numbers are 1/6 and 1/8
and exponential form means that we would have to write these numbers in such a way that the number can be expressed in the form 10 raised to the power of an integer.
When we solve 1/6
we will get 1/6 = 0.166
and when we solve 1/8 we will get
1/8 = 0.125
thus when we multiply 1/6 × 1/ 8 = 1/32
which when solved will give us
0.03125
this can be expressed as 3.125 × [tex]10^{-5}[/tex]

Anna saved $40 each month from babbysitting for 1 and 1/4 years. She spends 70% of her savings on a computer
how much money does she have left
( write the answer as a decimal to 2 places.)
The money left for Anna is $180 which was earned by babysitting for 15 months.
What is meant by the term percentage?To calculate a percentage, divide the value by the total value and multiply the result by 100.For the given question;
Monthly saving of Anna is $40.
Total time of babysitting is 1 and 1/4 years.
Total time = 5/4 years = 15 months.
Total money saved = 15 × $40 = $600.
70% of the money is spent
Thus, 30 % money is left.
Find 30% of $600
= 30 × 600/ 100
= $180.

Identify the graphs of y 2|x+2|-6 and y=-2 in the same coordinate plane
The graphs of the absolute value function y = 2|x + 2| - 6 and the horizontal line y = -2 are given on the image at the end of the answer.
How to build the graphs?The definition of the absolute value function is given as follows:
y = |x - h| + k.
In which the coordinates of the vertex are (h,k), representing the turning point of the graph of the absolute value function, the point in which the function makes the "V".
In this problem, the definition of the function is:
y = 2|x + 2| - 6.
Hence the coordinates of the vertex are:
(-2, -6).
The multiplication by 2 represents a vertical stretch but is not related to the vertex of the function.
y = -2 is a horizontal line, and the graph with these two functions is given by the image at the end of the answer.

The selling price of a refrigerator, is $548.90. The markup value was 10%. How much was the refrigerator originally?
Let the original price be p.
Then
p + (10% of p) = 548.90
1.1p = 548.90
p = 548.9 / 1.1 = $499.00
Hence the refrigerator was $499.00 originally

Step-by-step explanation:
y = 1/4 is the equation of a horizontal line parallel to the x- axis.
A line perpendicular to it will be a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 6, - 9 ) with equation
x = - 6 →
Option B
Answer:
B
Step-by-step explanation:
y = [tex]\frac{1}{4}[/tex] is the equation of a horizontal line, parallel to the x- axis and passing through all points with a y- coordinate of [tex]\frac{1}{4}[/tex]
A line perpendicular to it will be a vertical line parallel to the y- axis, with equation

the line passes through (- 6, - 9 ) with x- coordinate - 6 , then
x = - 6 ← equation of perpendicular line
Which angles are coterminal with -6pie/5
4π/5 and -16π/5 are Coterminal angles with -6π/5
What is Angle?an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle
Coterminal angles are angles that share the same initial and terminal sides. To find an angle coterminal to another you can do so by simply adding or subtracting any multiple of 360 degrees or 2 pi radians.
The given angle is -6π/5
We need to add 2π for finding coterminal angle
-6π/5+2π
4π/5
We need to subtract 2π for finding coterminal angle
-6π/5-2π
-6π-10π/5
