Every day, Ed's orange juice stand uses 2/3 of a bag of oranges. How many days will 2 2/3 bags of oranges last?
Answers
4days
Step by step solved:
If 2/3 of a bag of oranges is used every day, then in one day Ed's orange juice stand uses:
2/3 * 1 = 2/3
of a bag of oranges.
To find out how many days 2 2/3 bags of oranges will last, we can divide the total amount of oranges by the amount used each day:
2 2/3 = 8/3
8/3 ÷ 2/3 = 8/3 × 3/2 = 12/3 = 4
Therefore, 2 2/3 bags of oranges will last Ed's orange juice stand for 4 days.
Answer:
4 days
Step-by-step explanation:
2 2/3 ÷ 2/3
2 2/3 = \(\frac{3}{3}\) + \(\frac{3}{3}\) + \(\frac{2}{3}\) = \(\frac{8}{3}\) (\(\frac{3}{3}\) is another name for 1)
\(\frac{8}{3}\) ÷ \(\frac{2}{3}\) = \(\frac{4}{1}\) = 4

Petra is making a batch of extra large donuts by stamping circles in dough using a pastry stamp with a diameter of 5 inches. For the donut hole, she stamps out a circle using a pastry stamp that has a diameter of 2 inches.
How many square inches of dough are left in the donut after the hole has been removed?
Step 1 - Find the radius of each circle
Step 2 - Find the area of the large circle
Step 3 - Find the area of the small circle
Step 4 - Area of large circle minus area of small circle
Area = \(\pi\)²
Describe how you solved this problem using complete sentences and include all relevant formulas and calculations. Use 3.14 for \(\pi\)
Answers
Answer:
16.49
Step-by-step explanation:
First we are going to find the area of the larger circle. You don't need to find the radius, you can just use the diameter(the radius is 2.5). 3.14 times 2.5 squared=19.63. Next, the radius of the smaller circle is 1. So, 3.14 ^1 squared=3.14 19.63 - 3.14= 16.49

Terri is trying to save $250 so she can buy a new surfboard . She has \$75 saved already and plans to save $45 per week . How many weeks will it take her to save up enough money to purchase a new surfboard ?
Answers
Answer:
It will take Terri 4 weeks to save up enough money for a new surfboard.
Step-by-step explanation:
250-75= 175
175/45= 3.888
But its asking for whole weeks, so round to the nearest whole number, which is 4.
btw 45x4= 180 so she'll have 5 extra dollars.
x= number of weeks
250=75+45•x
75+45•x=250
45•x=250-75
45•x=175
x=175/45
x=3.88
Terri needs to save money for at least 4 weeks.
4•45=$180
$180+$75=$255
A thrift store was selling an Atari 2600 for $80 before deciding to have a 40% off promotion. A customer comes in to buy the console and pays with a 10% off any one item coupon. The coupon states that the 10% off coupon applies after any in-store promotions. The customer expects to get 50% off overall and pay 40.00. Is the customer correct?
Answers
Answer:
The customer is incorrect. They will pay $43.20 not $40.
Step-by-step explanation:
Since a thrift store is having 40% of $80, we have to calculate that. Doing so, we have to create proportions:
(The "/" sign is fraction)
1. x/80=40/100 2. 40*80=3200 3. x*100=100x 4. 100x=3200
5. x=3200/100 6. x=$32
Since $32 is 40% of $80, we have to do $80-$32=$48
So the thrift shop is lowering the price to $48.
But we can't forget about the 10% off coupon from the customer.
Now we have to find out what is 10% of $48. $48/10= $4.8
That's not our answer though. The final step is to do $48-$4.8 which gets our answer of $43.20 .

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Part A: To calculate the measures of center, we can find the median and the mean for each school.
For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.
To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.
For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.
To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):
18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.
Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.
The measures of center for Seaside School are: median = 15, mean ≈ 15.9.
Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.
For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.
To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.
For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.
To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.
Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.
The measures of variability for Seaside School are: range = 15, IQR = 6.
Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.
A retail store sells two types of shoes, sneakers, and sandals. The store owner pays $8 for the sneakers and $14 for the sandals. The sneakers can be sold for $10 and the sandals can be sold for $17. The owner of the store estimates that she won't sell more than 200 shoes each month, and doesn't plan to invest more than $2,000 on the inventory of the shoes. Let x= the number of sneakers in stock, and y=the number of sandals in stock. 1) Write an inequality that represents the possible amount of shoes she can purchase each month. 2) Next, write an inequality that represents how many sneakers and sandals she has in stock each month. 3) After graphing the constraints, what are the coordinates of the four vertices? Round your answers to the nearest whole number. 4)Write an equation to show the profit she will make on sneakers and sandals. 5)If she sold the number of sneakers and sandals that could maximize her profit, what would her maximum profit be?
Answers
Answer:
(1)\(x+y\leq 200\)
\(x>0, y> 0\)
(2)\(8x+14y\leq 2000\)
(3)From the graph, the coordinates of the four vertices are:
(0,143)(0,0)(133, 67)(200,0)(4)Profit Function: P(x,y)=2x+3y
(5)Maximum profit =$467
Step-by-step explanation:
Let the number of sneakers in stock =x
Let the number of sandals in stock =y
(1)The owner of the store estimates that she won't sell more than 200 shoes each month. Therefore, an inequality that represents the possible amount of shoes she can purchase each month is:
\(x+y\leq 200\)
\(x>0, y> 0\)
(2)She does not plan to invest more than $2,000 on the inventory of the shoes.
The store owner pays $8 for the sneakers and $14 for the sandals.
Therefore, an inequality that represents how many sneakers and sandals she has in stock each month is:
\(8x+14y\leq 2000\)
(3)From the graph, the coordinates of the four vertices are:
(0,143)(0,0)(133, 67)(200,0)(4)The sneakers can be sold for $10 and the sandals can be sold for $17.
Profit on one sneaker =$10-8=$2
Profit on one sandal =$17-14=$3
Profit Function: P(x,y)=2x+3y
(5)
At (0,143), Profit =2x+3y=2(0)+3(143)=$429
At (0,0), Profit =2x+3y=2(0)+3(0)=$0
At (133, 67), Profit =2x+3y=2(133)+3(67)=$467
At (200,0), , Profit =2x+3y=2(200)+3(0)=$400
Her maximum profit will be $467 when she sells 133 sneakers and 67 sandals.

A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.
Answers
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.

Nya wants to buy a sweater that had an orignial price of $55. The sweater is now discounted 20% and the sales tax rate is 5.5%. How much will Nya (Ichi Ni Sy Nya Arigatooo) pay for the sweater?
Answers
=46.42
Step-by-step explanation:
First step is to find the discount
Discount = original price * discount rate
= 55 * 20%
= 55* 20
=11
Take the discount from the original price and that is the new price
new price = original price - discount
= 55-11
=44
Now we need to find the tax
tax = new price * tax rate
= 44 * 5.5%
= 44*.055
=2.42
The final price is the new price plus the tax
final price = new price + tax
= 44+2.42
=46.42
