2. Mr. Andrew wants to give each of his students an equal number of the crayons he bought. There are 32 students in Mr. Andrew’s class. How many crayons will each student get?
Estimate first.
Solve the problem and explain your answer using pictures, diagrams, equations, and/or words.
3. How many more boxes of crayons does Mr. Andrew need if he wants each of his students to get 12 crayons? Explain your answer.
Answers
Answer:
Step-by-step explanation:
2.
Because we don't know how many crayons he bought we will call it c.
c = total number of crayons purchased
T = total number of crayons each student gets
To determine how many crayons each student gets we divide c by 32, because that's the number of students in his class.
c / 32 = T
So let's say he purchased 120 crayons.
c = 120
120/32 = T
T = 3.75
Since he can't give a fraction of a crayon, in this case, each student will get 3 crayons.
3.
We will now pretend there are 24 crayons in 1 box.
So T still equals the total number of crayons each student gets and c still equals number of crayons purchased, but now we also have b which equals the number of crayons in 1 box.
c = total number of crayons purchased
T = total number of crayons each student gets
b = number of crayons in 1 box
x = number of boxes purchased
So b*x = c
We can still write the equation:
c / 32 = T
We know T = 12 So we plug 12 in for T
c / 32 = 12 Now multiply each side by 32, so 32 will cancel on the left.
32c/32 = 12 * 32
c = 12 * 32
c = 384
So if he needs to purchase 384 crayons we can use our other equation.
b*x = c
b = 24
c = 384
So we plug those in.
24x = 384 Divide each side by 24 so 24 will cancel on the left.
24x/24 = 384/24
x = 384/24
x = 16
So he needs to buy 16 boxes of crayons in this instance. We can figure out how many boxes he bought in #2 by using the same equation.
b*x = c
c = 120 in #2
b =24
24 * x = 120
24x/24 = 120/24
x = 120/24
x = 5
So for each student to have 12 crayons he needs to purchase 11 more boxes (16 - 5 = 11).
This will work for whatever numbers you were given.
Remember:
c = total number of crayons purchased
T = total number of crayons each student gets
b = number of crayons in 1 box
x = number of boxes purchased
b*x = c
c / 32 = T
Jake, Becky, and Max are meeting at Charley's Pizza for dinner and then plan to go to a movie. When they arrive at the pizza place, each one of them has a different coupon. They decide to use the coupon that will give them the best deal. Jake's coupon is $19.99 for a pizza and pasta meal deal; Becky's coupon is for two large one-topping pizzas--each at of the menu price; and Max's coupon is for three medium one-topping pizzas -- each at off the menu price. According to the menu, a medium one-topping pizza is $8.99, and a large one-topping pizza is $14.89. They also spend $1.25 each for sodas and $5.00 on the tip. At the movie theater, Max has a coupon that's good for off a third movie ticket when you purchase two other movie tickets at the regular price. The regular price of each movie ticket is $9.80.
Although Jake, Becky, and Max plan to split the cost of the pizza and movie, they decide that with the coupons, it's just easier if one of them pays at each place. So, the friends agree that Jake will pay for the pizza and Becky will pay for the movies. At the end of the night, they'll figure out how much Max owes both Jake and Becky.
If Jake gives the server $30 at the pizza place, he should receive back ______
$1.50 in change (after leaving the tip).

Yes
Step-by-step explanation: Yes because you can show the hour and the miles; for eample, if it stops you can graph how many miles it does in an hour, so on and so forth
Since the train is traveling at a constant rate, a graph representing distance in miles compared to time in hours will show a proportional relationship.
You are driving from your house to your friend's house. The distance y (in miles) that you are from your friend's house after x minutes is y = −1/2x + 4. Graph the equation. Then determine how long it takes to drive from your house to your friend's house.

Answers
Answer:
The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.

Round -1.05 mm/year to –1.

The statement that is true of the box plot of this data set is:
"The right whisker will go from 150 to 200."
Option D is the correct answer.
What is the interquartile range?An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
The box plot of a data set displays the minimum, maximum, median, and quartiles of the data set.
The box represents the middle 50% of the data, with the median marked by a line inside the box.
The whiskers extend from the box to the minimum and maximum values that are not outliers.
Given the information about the data set, we know that:
The median is 145, which means that the line inside the box will be at 145.
The upper quartile is 150, which means that the top of the box will be at 150.
The lower quartile is 120, which means that the bottom of the box will be at 120.
The minimum is 115, which means that the left whisker will go from 115 to the bottom of the box (which is 120).
The maximum is 200, which means that the right whisker will go from 150 (the top of the box) to 200.
Therefore,
The statement that is true of the box plot of this data set is:
"The right whisker will go from 150 to 200."
