3. 0.05x
4. x + 0.05
Answer:
1. 0.95x
Step-by-step explanation:
The amount of the discount is 0.05x, so the discounted price is ...

If you have a coupon for an additional 30% off after the markdown, how much will the bike cost if it was originally $950. 00?.
Percentage is represented by '%' symbol. The final cost of the bike will be equal to $490.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
Given to us
The initial cost of the bike, P = $950
Additional coupon = 30%
Marked down = $200
We know the original cost of the bike which is $950. therefore, when the price of the bike was marked down, its cost will be,
$900 - $200 = $700
Thus, the marked-down cost of the bike will be $700.
As it is given that we have an additional 30% off after the markdown, therefore, cost of the bike will be 70% of the marked price,
[tex]70\%\ of\ \$700\\\\ = 0.70 \times 700\\\\= \$490[/tex]
Hence, the final cost of the bike will be equal to $490.

Jessica uses a food delivery service to order dinner. She paid $27.44 for dinner, which included the cost of the food and a delivery
fee, which was 12% of the cost of the food
What was the cost of Jessica's dinner before the delivery fee?
Enter your answer in the box
Answer:
3.29
Step-by-step explanation:
Turn 12% to 0.12.
Multiply 27.44 times 0.12.
Answer:
$24.50
Step-by-step explanation:
Total cost = food cost + (food cost x 12%)
27.44 = x + (x • 0.12)
(rearrange and distribute)
1x + 0.12x = 27.44
(solve for x)
1.12x = 27.44
x = 27.44 / 1.12 = 24.50
Original food cost is $24.50

To convert a temperature measured in degrees Fahrenheit to degrees Celsius, there is a formula
C=5/9(F-32)
where C represents the temperature in degrees Celsius and F represents the temperature in degrees Fahrenheit.
If a temperature is 113`F, what is that temperature measured in Celsius?
Answer:
113`F= 46.11° Celsius
Step-by-step explanation:
(Celsius°C × 9/5) + 32 = Fahrenheit
(Celsius°C × 9/5) + 32 = 113
(Celsius°C × 9/5) = 113 - 32
(Celsius°C × 9/5) = 83
Celsius = 5(83)/9
Celsius = 46.11° Celsius
[tex]\\ \tt\hookrightarrow C=5/9(F-32)[/tex]
[tex]\\ \tt\hookrightarrow C=5/9(113-32)[/tex]
[tex]\\ \tt\hookrightarrow C=5/9(81)[/tex]
[tex]\\ \tt\hookrightarrow C=5(9)[/tex]

Lee recorded the number of push ups he did each each day for six days his data are listed below 68,41,58,75,48,40 what are the mean and the median of lees data set
Hleppppp please
Answer:
mean : 55; median : 53
Step-by-step explanation:
Given inputs: 68, 41, 58, 75, 48, 40
total numbers of input = 6
total value = 68 + 41 + 58 + 75 + 48 + 40 = 330
Mean → total value / total numbers of input = 330 / 6
= 55
arrange in increasing order: 40, 41, 48, 58, 68, 75
we can see that the median is between, 48 and 58,
so median → (48+58)/2 → 53

Coach Brown had to buy baseballs for his team. He bought practice baseballs at $1.75 each, rubber pitching machine balls at $2.80 each, and leather game balls at $6.25 each. He bought 250 balls in total, and 20 fewer game balls than pitching machine balls.
If the total came to $974.65, then how many of each ball were ordered?
A. 130 practice, 113 machine, and 93 game balls
B. 44 practice, 113 machine, and 93 game balls
C. 206 practice, 113 machine, and 93 game balls
D. 114 practice, 113 machine, and 73 game balls
44 practice, 113 machine, and 93 game balls
===========================================================
Explanation:
x = number of practice baseballsy = number of pitching machine baseballsz = number of game ballsHe bought 20 fewer game balls than pitching machine baseballs, which means,
z = y-20
Since the coach bought 250 baseballs total we can also write
x+y+z = 250
Let's replace z with y-20 and simplify
x+y+z = 250
x+y+y-20 = 250
x+2y = 250+20
x+2y = 270
Now let's calculate the subtotal costs for each type of baseball
1.75x = cost of just the practice baseballs2.80y = cost of just the pitching machine baseballs6.25z = cost of just the leather game balls.Those subtotals add to this
1.75x+2.80y+6.25z = total cost = $974.65
1.75x+2.80y+6.25z = 974.65
Like before, I'll replace z with y-20
1.75x+2.80y+6.25(y-20) = 974.65
1.75x+2.80y+6.25y-125 = 974.65
1.75x+9.05y = 974.65+125
1.75x+9.05y = 1099.65
------------------------------
So far we have this system of equations
[tex]\begin{cases}x+2y = 270\\1.75x+9.05y = 1099.65\end{cases}[/tex]
I'll use substitution to solve the system.
Isolate x in equation (1)
x+2y = 270
x = 270-2y
Then plug this into equation (2) and solve for y.
1.75x+9.05y = 1099.65
1.75(270-2y)+9.05y = 1099.65
472.5-3.5y+9.05y = 1099.65
472.5+5.55y = 1099.65
5.55y = 1099.65-472.5
5.55y = 627.15
y = 627.15/5.55
y = 113
There are 113 pitching machine baseballs.
Use this y value to find x
x = 270-2y
x = 270-2(113)
x = 270-226
x = 44
There are 44 practice baseballs.
Also, we can say,
z = y-20
z = 113-20
z = 93
There are 93 game balls.
------------------------------
Check:
x+y+z = 44+113+93 = 250 baseballs total
A = 1.75*x = 1.75*44 = 77 = cost of just the practice baseballsB = 2.80*y = 2.80*113 = 316.40 = cost of just the pitching machine baseballsC = 6.25*z = 6.25*93 = 581.25 = cost of just the game ballsA+B+C = 77+316.40+581.25 = 974.65 = total cost
Everything checks out. Also note that value of z is 20 fewer than the value of y.
Natasha is a regional manager for a chain of supermarkets. She has been tasked with researching the weekly sales records of two branch locations over the past month, which she must present to her board of directors. She was able to assemble the relevant information in the table below, but it is scrambled and hard to read. Sales are listed in thousands of dollars. Week 4 1 1 3 4 2 3 2 Sales 16. 3 17. 8 23. 1 15. 2 20. 2 23. 4 22. 9 17. 6 Branch North South North South South North North South In order to make the data more readable, Natasha has decided to put it into a graph. Which of the following graphs accurately matches the information in the table? I. A bar graph has week on the x-axis and sales (dollars times 1,000) on the y-axis, from 15 to 23. Week 1 North, 23. 1; week 2 north, 23. 4; week 3 north, 22. 9; week 4 north, 16. 3. Week 1 south, 17. 8; week 2 south, 17. 6; week 3 south, 15. 2; week 4 south, 20. 2. II. A line graph has week on the x-axis and sales (dollars times 1,000) on the y-axis, going from 15 to 23. III. A graph has week on the x-axis and sales (dollars times 1,000) on the y-axis, going from 15 to 23. Points are plotted all over the graph. IV. A pie chart titled Sales (dollars times 1,000). North 1, 16. 3; North 2, 17. 8; North 3, 23. 1; North 4, 15. 2; South 1, 20. 2; South 2, 23. 4; South 3, 22. 9; South 4, 17. 6. A. I b. II c. III d. IV.
The graph which accurately matches Natasha's data for chain of supermarkets is bar graph.
How to read the data from the table?Table is a way to represent the data of the two or more variable.
To read the data from the table look for the value of one variable, and get the resultant value of other variable from the corresponding block.
Natasha was able to assemble the relevant information in the table below,
Sales listed in thousands of dollars.
Week - 4 1 1 3 4 2 3 2
Sales- 16.3 17.8 23.1 15.2 20.2 23.4 22.9 17.6
Branch- North South North South South North North South
To show the sales with respect to the time period, the best data chart is the bar graph. In a bar graph, the height of the bars is proportional to the data value it posses.
Here , for the sales by the Natasha the bar graph should be used as, the bar graph has week on the x-axis and sales (dollars times 1,000) on the y-axis, from 15 to 23.
Week 1 North, 23. 1; week 2 north, 23. 4; week 3 north, 22. 9; week 4 north, 16. 3. Week 1 south, 17. 8; week 2 south, 17. 6; week 3 south, 15. 2; week 4 south, 20. 2.
Hence, the graph which accurately matches Natasha's data for chain of supermarkets is bar graph.
