Part A (4 points): Tonya selected a pair of shoes for the regular price of $80. How much money will she save by using the 20% off coupon? Justify your answer using equations, models, and/or words to explain your mathematical reasoning. I need the answer and the model and how you got the answer by tomorrow, Thx. :) Will Medal!
20% = 0.20
multiply original price ( $0) by 0.20 for the amount of discount then subtract it
80*0.20 = 16.00
she will save $16
80-16 = 64
she will pay $64 after the discount

A number changed to 12.6 after it was rounded. To what place waa the number rounded? Explain how you know
Answer:
The number round to nearest tenths.
Step-by-step explanation:
Given : A number changed to 12.6 after it was rounded.
To find : To what place was the number rounded?
Solution :
The number round when the last digit place value is greater than 5, then before that number rounds by 1 and change the number.
In number 12.6 it was rounded to the nearest tenths.
Which means the hundredths place is greater than 5 either 6,7,8 or 9 and the tenths place is definitely 5.
So, the number can be 12.56, 12.57, 12.58, 12.59
If they all round we get the number 12.6.

Step-by-step explanation:
Write an equation of the line that passes through (18, 2) and is parallel to the line 3y - x = -12
To find the equation of a line parallel to 3y - x = -12 that goes through the point (18, 2), first find the slope of the given line, which is 1/3. Then, use the point-slope form with the given point and the slope to write the equation of the desired line, which is y = (1/3)x - 4.
Explanation:To write an equation of the line that passes through the point (18, 2) and is parallel to the line 3y - x = -12, we first need to find the slope of the given line. For a line to be parallel, it must have the same slope as the line to which it is parallel. We start by putting the equation of the given line in slope-intercept form (y = mx + b).
First, isolate y:
3y = x - 12
y = (1/3)x - 4
The slope (m) of the given line is 1/3. Our parallel line should have the same slope, so we'll use this slope and the point (18, 2) in the point-slope form of a line equation, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line.
Now, plug in the values:
y - 2 = (1/3)(x - 18)
This is the point-slope form of the equation for our parallel line. To put it into slope-intercept form, we distribute and simplify:
y - 2 = (1/3)x - 6
y = (1/3)x - 4
If you are making a scale drawing of a giraffe that is 6m tall, and the height of the giraffe in your drawing is 3 cm, what is the scale of the drawing?
Answer:
The scale of the drawing of girrafe is [tex]1:200[/tex].
Step-by-step explanation:
Given: scale drawing of a giraffe that is [tex]6\rm\;{m}[/tex] tall, and the height of the giraffe in your drawing is [tex]3\rm\;{cm}[/tex].
As per question,
Dimension of giraffe is [tex]6\rm\;{m}[/tex] tall and height is [tex]3\rm\;{cm}[/tex].
For scaling the drawing, the given unit must be same.
As we know that,
[tex]1\rm\;{m}= 100\rm\;{cm}\\6\rm\;{m}=600\rm\;{cm}[/tex]
Therefore, scale of the drawing is [tex]3\rm\;{cm}:600\rm\;{cm}=1:200[/tex].
Hence, the scale of the drawing is [tex]1:200[/tex].

If the consumer price index changes from 125 in september to 150 in october, what is the rate of inflation?
a. 20.0%
b. 16.7%
c. 9.1%
d. 45.5%
If the consumer price index changes from 125 in september to 150 in october, the rate of inflation is a. 20.0%
Further explanationInflation is a sustained increase in the general price level of goods and services in an economy over a period of time. When inflation is too high, it is not good for the economy or individuals. Inflation always reduce the value of money, unless interest rates are higher than inflation. The less chance there is that savers will see the real return on their money if the inflation gets higher. There are causes of inflation such as demand-pull and Cost-push. They are responsible for a general rise in prices in an economy.
Policies to reduce inflation are such as monetary policy (Higher interest rates), Tight fiscal policy (Higher income tax and/or lower government spending that will reduce aggregate demand and leading to lower growth and less demand pull inflation).
The rate of inflation = 20%.
September's price = 125
October's price = 150
Rate of inflation = [tex]\frac{(150-125)}{125} * 100[/tex]
[tex]\frac{25}{125 } *100[/tex]
[tex]=0.2 * 100 \\= 20%[/tex]

A machine laying underground cable can place 125 meters of cable in 5 minutes What is the rate per minute
divide 125 by 5
125 /5 = 25 meters per minute
Answer:
The rate per min is, 25 meters/minute
Step-by-step explanation:
Unit rate is defined as when rates are expressed as a quantity of 1, such as 4 feet per second or 6 miles per hour, they are called unit rates.
Given the statement: a machine laying underground cable can place 125 meters of cable in 5 minutes.
Then by definition:
rate per minute = [tex]\frac{125}{5} = 25[/tex] meters /minute
therefore, the rate per minute is, 25 meters/ minute

help .. Solve the literal equation cy−7=5d+3y for y .
The literal equation cy - 7 = 5d + 3y can be solved for y by first bringing all the y terms to one side, and then factoring y out and dividing by the remaining coefficient to isolate y. The solution is y = (5d + 7) / (c - 3).
To solve the literal equation cy - 7 = 5d + 3y for y, we need to isolate y on one side of the equation. First, we want to bring all the terms containing y to one side and the rest to the other side. We achieve this by subtracting 3y from both sides of the equation and adding 7 to both sides, leading to cy - 3y = 5d + 7.
Now, we factor y out of the terms on the left side thus: y(c - 3) = 5d + 7. Finally, we divide both sides by (c - 3) to get y by itself: y = (5d + 7) / (c - 3). Therefore, we have isolated y and expressed it in terms of c and d.
