Answer:
With the discounts, you saved a total of $4.90. You still owe $29.10.
Step-by-step explanation:
Shoes:
10% of 24 is 2.4
The shoes cost 21.60 with the 10% discount and before tax.
Belt:
25% of 10 is 2.5
The belt cost $7.50 with the 25% discount and before tax.
Total:
You still owe 29.10 for the belt and shoes before tax.
You saved $2.4 on the shoes and $2.5 on the belt (total of $4.90)

Step-by-step explanation:
s=180(8-2)
s=1080
So
106+(180-11x)+(180-12x)+143+(180-17x)+130+(180-12x)+137=1080
-52x=1080-1236

The Johnson party had a good hunt. They bagged a total of 26 deer which included some
big bucks, little bucks and some does. The number of does is 5 more than twice the amount of
little bucks. The number of big bucks was half as many as little bucks. How many big bucks,
little bucks and does did the party get?
9514 1404 393
Answer:
3 big bucks6 little bucks17 doesStep-by-step explanation:
Let B, L, D represent the numbers of big bucks, little bucks, and does, respectively.
B + L + D = 26 . . . . . . total bagged
D = 5 + 2L . . . . . . . . . 5 more does than twice the number of little bucks
B = L/2 . . . . . . . . . . . . half as many big bucks as little bucks
__
We can substitute for B and D in the first equation:
L/2 + L + (5 +2L) = 26
7/2L = 21 . . . . . . . . . . . . . subtract 5, collect terms
L = 6 . . . . . . . . . . . . . . . . . multiply by 2/7
D = 5 + 2·6 = 17
B = 6/2 = 3
The party bagged 3 big bucks, 6 little bucks and 17 does.
In 40 minutes; diane walks 2.5 miles and sue walks 1.5 miles. in miles per hour , how much far diane walking?
Diane will walk 1.5 miles more than Sue.
Firstly calculating the speed of Diane and Sue in miles per hour. As per the known fact, 1 hour has 60 minutes.
In 40 minutes Diane walks distance = 2.5 miles
So, converting speed in miles per hour = (2.5 ÷ 40)×60
Speed of Diane in miles per hour = 3.75 miles per hour
In 40 minutes Sue walks distance = 1.5 miles
So, converting speed in miles per hour = (1.5 ÷ 40)×60
Speed of Sue in miles per hour = 2.25 miles per hour
Difference between the distance covered = 3.75 - 2.25
Performing subtraction
Difference between the distance covered = 1.5 miles
Hence, Diane will walk 1.5 miles more than Sue.

What is the slope of the line? Please explain your answer.
A.) m=5
B.) m= -5
C.) m=1/5
D.) m= -1/5
Answer: D
Step-by-step explanation: Assuming the left point is A at (-2,2) and the right point is B at (3,1) we can determine the slope by using the “Rise over Run” rule where the change in Y is the “Rise” and the change in X is the “Run”. By setting up the equation y2-y1/x2-x1 we can plug in the coordinates from the variables and get 1-2/3+2 which leaves us with our answer m= -1/5
Write the Slope-Intercept and Point-Slope forms of the line passing through the point (-3, 2) and having a slope of -4/5
Answer:
slope-intercept: [tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]
point-slope: [tex]y-2=\frac{-4}{5} (x+3)[/tex]
Step-by-step explanation:
The slope-intercept form of a line is written as y = mx + b, where m is the slope and b is the y-intercept.
The point-slope form of a line is written as y - y1 = m(x - x1), where (x1, y1) is a given point and m is the slope.
Here, we see that the slope is -4/5, which means that m = -4/5. Since we're given a point (-3, 2), let's go ahead and just write the point-slope form already. (x1, y1) = (-3, 2) so x1 = -3 and y1 = 2. Then:
y - y1 = m(x - x1)
y - 2 = (-4/5) * (x + 3)
[tex]y-2=\frac{-4}{5} (x+3)[/tex]
Now, we want to find the slope-intercept form, so we need to figure out the y-intercept. Well, first, let's plug in what we know:
y = mx + b
y = (-4/5)x + b
Any point on this line will satisfy the above equation. Since (-3, 2) is on this line, if we plug -3 in for x and 2 in for y, the equation should hold true, so we can solve for b:
y = (-4/5)x + b
2 = (-4/5) * (-3) + b
2 = 12/5 + b
b = -2/5
So, the y-intercept is -2/5. Then the slope-intercept form is:
[tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]
Thus, our two equations are:
slope-intercept: [tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]
point-slope: [tex]y-2=\frac{-4}{5} (x+3)[/tex]
at a popular night club, the ratio of women to men is 20:11. if 7 men arrived to the club, the ratio would be 3:2. how many men are currently at the party?
Before there were 33 men and then 7 men arrive total men are 40.
• In mathematics, ratio is an ordered pair of numbers x and y, written x/y where value of y is not equal to 0. A proportion is an equation In which two ratios are made equal to each other.
Since the initial ratio is 20 : 11,
Lets assume there are 20x women and then the number of men will be 11x.
If 7 men arrive more the ratio will become 3 : 2
20x / (11x + 7 ) = 3/2
40x = 33x + 21
7x = 21
x = 3
Initial men = 11x = 11(3) = 33
When 7 more men arrive , total men = 33 + 7 = 40
Before there were 33 men and then 7 men arrive total men are 40.

Doug and Emily are driving cars on a track, and they both do 20 laps around a 1-mile track. Doug drives an average of 60 miles per hour around the track while Emily drives at an average of 80 miles per hour. When Emily finished her 20 laps how many laps does Doug have left?
Answer:
When Emily finishes 20 laps Doug has to finish 5 laps.
Step-by-step explanation:
To find how many laps does Doug have left, we need to calculate the time that Emily takes to finish 20 laps:
[tex] t = \frac{x}{v} [/tex]
Where:
x: is the distance = 1 mile
t: is the time
v: is the speed of Emily = 80 mi/h
The time that takes Emily to do 20 laps is:
[tex] t = 20*\frac{1 mile}{80 mile/h} = 0.25 h [/tex]
Now, we can find the number of laps:
[tex]x = v*t = 60 miles/h*0.25 h = 15 miles*\frac{1 lap}{1 mile} = 15 laps[/tex]
[tex] laps = 20 - 15 = 5 [/tex]
Therefore, when Emily finishes 20 laps Doug has to finish 5 laps.

What is algebraic operations?Algebraic operation is any one of the common operations of arithmetic, Which include addition, subtraction, multiplication, division, raising to a Whole number power, and taking roots (fractional power). These Procedures could be applied to numerical data, in which case they are Frequently referred to as arithmetic operations. Similar operations can be Carried out on variables, algebraic expressions, and, more generally, on Components of algebraic structures like groups and fields. A Mathematical operation could also be defined simply as a function from a Cartesian power of a set to the same set.
Given that:school uses 13,470 pieces of white paper, 7,970 fewer pieces of blue paper than white paper, and 2,400 fewer pieces of yellow paper than blue paper.
The school uses 22,070 pieces of paper in all.
IT is already given that the school uses 13,470 pieces of white paper. Then it says that there are 7,970 fewer pieces of blue paper than white Paper. So if you subtract 7,970 from 13,470, you get that the school used 5,500 pieces of blue paper. Then it says that there are 2,400 fewer Pieces of yellow paper than blue paper. So when you subtract 2,400 From 5,500, you get that the school used 3,100 pieces of yellow paper. So if you do 13,470+5,500+3,100, you get that the school used 22,070 Pieces of paper in total.

x and y-intercept :
The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.
Absolute min:
An absolute maximum point is a point where the function obtains its greatest possible value.
Absolute max :
An absolute minimum point is a point where the function obtains its least possible value.
Local Extrema (Local Maxima/Minima): The local maxima and minima on a graph refer to the maximum and minimum points of the graph over a specific interval of the graph as opposed to the entire graph, so there can be multiple local maxima and minima of a given graph.
When considering which points are the absolute maximum and the absolute minimum of a graph, we not only need to consider local extrema (a maximum/minimum of a graph on some interval that contains the point), but we also need to consider the endpoints (the furthest left/right points on our graph). By looking at the y-values for each of these points, we can identify the absolute maximum of the graph as the point with the highest y-value, and we can identify the absolute minimum as the point with the lowest y-value.
Step 1: Identify local maxima/minima, as well as the endpoints.
From this graph, we can see that our graph is on the interval
This means we have our endpoints at [-1,-1] , [4,1] ,
to consider. We also observe that we have one local minima and one local maxima in between these points on our interval. The estimated points are all shown in the image.
