5 Figure N is a rectangular prism that has twice the volume of figure M. How many layers and how many cubes in each layer could there be in figure N?
Answers
The number of layers of M and in N in 2
How many layers and how many cubes in each layerWe do know that Figure N has twice the volume of Figure M. Since both figures are rectangular prisms, their volumes can be calculated using the formula:
Volume = length x width x height
Let's say that Figure M has a length of L, a width of W, and a height of H.
Then its volume is:
Volume_M = LWH
Since Figure N has twice the volume of Figure M, we can write:
Volume_N = 2 x Volume_M
Substituting the formula for Volume_M, we get:
Volume_N = 2LWH
This means that two layers of M and in N
The number of cubes cannot be determined with the available information

Suppose instead that one friend bought all 4 bags of pretzels and another friend bought all 4 drinks write an expression that shows the total cost
Answers
Answer:
4x+4y=total cost
Step-by-step explanation:
We are given that there was a total of 4 bags of pretzels and 4 drinks bought. We are also given to write an expression using x dollars for the pretzels and y dollars for the drinks.
To do this, we need to multiply the cost of each pretzel bag, x, by the total amount of bags of pretzels purchased.
4·x
=4x
Next, we need to multiply the cost of each drink, y, by the total number of drinks purchased:
4·y
=4y
The question is asking us to write an expression, so put 2 and 2 together:
4x+4y=total cost
Given the actual question, "Suppose instead..." the expression would be the same.
Hope this helps! :)

Kyle has a storage box that is 2 ft. long, 3 ft. high, and has a volume of [tex]12ft^{3}[/tex]
Myla has a storage box that is 4 ft. high, 2 ft. long, and has a volume of [tex]16ft^{3}[/tex]
What are the widths of Kyle and Myla's boxes? Explain how you know.
help please! and please have easy explanation that's easy to understand :))
Answers
Answer:
OK so, volume= length x width x height
so, if the length of kyles box is 2, and his height is 3, but the volume is 12, then the width would be 2.
2 x 2 x 3=12
however, for myla, if her box is, 2 feet long and 4 feet high, but the volume is 16, then, her width is also 2.
2 x 2 x 4= 16
a way to look at this is, in the problem you are given the height and length, so, if its length times width times height, take your given length and multiply it by a number that will make it equal your given volume.
for example, let q=width, let m=height, and let j=length, p=volume, h=random variable.
j (x) h (x) m=p
its your job to find h.

Three park rangers had to report on the ways visitors use their facilities. Each ranger surveyed a sample of park visitors. Determine whether or not each sampling described is random or biased.
Answers
Answer:
To determine whether a sampling is random or biased, we need to know how the sample was selected. Here are three possible scenarios:
Ranger 1 stands at the entrance to the park and surveys the first 100 visitors who arrive.
This sampling is biased, as it only includes visitors who arrived early in the day. Visitors who arrive later in the day may have different characteristics or behaviors, so this sample may not be representative of all park visitors.
Ranger 2 selects every 10th visitor who enters the park and surveys them.
This sampling is random, as every 10th visitor is selected without bias. This method is called systematic sampling.
Ranger 3 surveys visitors who are leaving the park on a rainy day.
This sampling is biased, as visitors who come to the park on a rainy day may have different motivations or behaviors than visitors on a sunny day. This sample may not be representative of all park visitors.
In summary, sampling methods that are random, such as systematic sampling, are preferred over biased sampling methods in order to obtain a representative sample of the population of interest.
Answer: Depending on the situation
Step-by-step explanation: For a sample to be random, everyone/thing has to have an equal chance of getting selected. Ex. One of the park rangers asked everyone in one part of the park. - This example would be biased because the people who weren't in that part of the park had less of a chance of being picked

A store is running a "buy 3 get 2 free" promotion on twelve-packs of soda. Each twelve-pack costs $5.49. How much will Peter pay for 25 twelve-packs of soda?
Answers
Answer: $82.35
Step-by-step explanation:
For every 3 you buy, you get 2 free. This means out of every 5 twelve-packs, you pay for 3 of them, or 60%.
3/5 = 0.6 or 60%
So, if you buy 25 of them, you pay for 60% of 25 twelve-packs, or 15 of them.
25 x 0.6 = 15
If you are paying for 15 twelve-packs, and each one is $5.49, then the total would be $82.35.
15 x 5.49 = 82.35
Answer:82.35
Step-by-step explanation:
For every 3 you buy, you get 2 free. This means out of every 5 twelve-packs, you pay for 3 of them, or 60%.
3/5 = 60%
if you buy 25 of them, you pay for 60% of 25 twelve-packs, or 15 of them.
25 x 0.6 = 15
15 twelve-packs, each one is $5.49, then the total would be $82.35.
15 x 5.49 = 82.35
a 4 year loan with 6% simple interest? Find the total amount paid, interest paid, and the monthly payment.
Answers
To find the total amount paid, interest paid, and monthly payment for a 4-year loan with 6% simple interest, we need to know the principal amount of the loan. Let's assume the principal amount is $10,000.
Total amount paid = Principal + Interest
Interest = Principal x Rate x Time
Time = 4 years
Interest = $10,000 x 0.06 x 4 = $2,400
Total amount paid = $10,000 + $2,400 = $12,400
To find the monthly payment, we can divide the total amount paid by the number of months in 4 years (48 months).
Monthly payment = $12,400 / 48 = $258.33 (rounded to the nearest cent)
Therefore, the total amount paid is $12,400, the interest paid is $2,400, and the monthly payment is $258.33.

Using a ruler, the Year 1 cube has side length 5 units.
Using the same ruler, the Year 5 cube has side length 18 units.
The volume of the Year 5 cube is 5832 units³. The volume of the Year 1 cube is 125 units³.
The ratio of the volumes of Year 5 cube to the Year 1 cube is
5832/125 = 47:1
The ratio of sales of Year 5 to Year 1 is
81235/15405 = 5:1
The sales of Year 5 are approximately 5 times the sales of Year 1, tbut the cube of Year 5 has approximately 47 times the volume of the cube of Year 1. The graph is misleading because the volumes of the cubes are not proportional to the amounts of sales.
d) 47 times in volume

Adam is purchasing a new television that costs $2,187.96 after tax. He borrowed the money from his parents and must pay back the full amount plus simple interest at the rate of 3.5%. What is the total amount he will pay if he takes 2 years to pay his parents back? (Include Decimal with the cents; No Commas)
Answers
Basic Interest
When there is only one compounding every time period, simple interest is applied.
The formula for calculating interest after t years is 1 = Prt.
Where P is the initial sum and r is the interest rate in decimal form.
The following are the parameters for this problem:
P = 2187.96, r = 0.035, t = 2.
The interest will therefore be paid at the rate of 1=Prt = 2187.96 x 0.035 2 = $153.16.
