Tasha has foam blocks stored in a box that measures 2 1/4 ft long by 2 ft wide by 2 ft tall. Each foam block is a cube with 1/2ft edge length. How many blocks can fit into the box?
Answers
Answer:
72
Step-by-step explanation:
First, you need to calculate the volume of the box:
2 1/4 × 2 × 2 = 9 (ft³)
Second, calculate the volume of the foam block:
1/2 × 1/2 × 1/2 = 1/8 (ft³)
In the end, get the volume of the box divided to the volume of the foam block:
9 ÷ (1/8) = 72 ( foam blocks)
Conclusion, the answer is 72 foam blocks

{30 POINTS} For a promotion, a store offers to pay the sales taxes on any item
you buy. You are actually paying taxes but they are calculated on
a lower price.
Suppose you buy an item for $100.
The sales taxes are 15%.
a) What is the true sale price of the item?
b) How much tax are you really paying?
Answers
--Answer--
1. $85
2. $15
--Explanation--
1. 15% off of 100 just means moving the decimal in 15 over by 2 to the left.
From there, multiply 100 x 0.15.
Then you get 15, so that's how much tax you are paying. Meaning Subtract 15 from 100 to get the price it originally was before tax. 100 - 15 = 85.
2. $15 dollars tax from moving decimal 2 to the left of 15%.
Which scenario can be modeled by the linear function

The sum of the digits of a two-digit number is 5. If nine is subtracted from the number, the digits will be reversed. Find the number.
If the tens digit is x, then the equation is:
The number is:
Answers
Answer: 32
Step-by-step explanation:
The only numbers that can have 2 digits and two of which equal to five can only be:
3+2
2+3
4+1
1+4
So the numbers are: 41,14,23, and 32.
41-9=32
14-9=5
23-9=14
32-9=23
Since the question is asking for the number who’s difference is the reverse of one of the numbers. The only possible answer is 32 because 32-9= 23. (23 is the reverse of 32)
3+2 is equal to 5
32 - 9 is equal to 23 witch is the reverse of 32

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.

The table below shows the relationship between the cost of renting a movie (in dollars) to the number of days the movie is rented.
Based on the table below is y proportional to x?
Answers
Please help. Use the steps to finish writing an equivalent equation for y in terms of x. −6x = 12 − 4y 1. Subtract 12 from both sides: −6x − 12 = −4y 2. Divide −4 to both sides: −6x − 12 −4 = −4y −4 x + 3 = y
Answers
Answer:
3/2 x +3 = y
Step-by-step explanation:
−6x = 12 − 4y
Subtract 12 from both side
−6x-12 = 12 − 4y-12
-6x -12 = -4y
Divide both side by -4
(-6x -12)/-4 = -4y/-4
-6x/-4 -12/-4 = y
3/2 x +3 = y
Answer:
y = 1.5x + 3
Step-by-step explanation:
= - 6x - 12 = - 4y
(- 6x - 12)/- 4 = - 4y/- 4
1.5x + 3 = y

\(\frac{1}{8} \)

Step-by-step explanation:
Basically, you plug the x value that is in the left column into the x in the equation f(x)=8ˣ.
For -2, it would be f(-2)=\(8^{-2} \).
Solve: any number with a negative exponent is 1/[that number], so this would be 1/(\(8^{2} \))
= 1/64 <- because 8*8=64
*The f(-2) or f(x) (or f([any number]) )is just showing the output of the function 8ˣ.
For -1, it would be f(-1)=\(8^{-1} \).
Solve: any number with a negative exponent is 1/[that number], so this would be 1/(\(8^{1} \))
= 1/8 <- because any number to the first power is just that number.
For 0, it would be f(0)=\(8^{0} \).
Solve: any number with an exponent that is zero is just 1
\(8^{0} \) = 1
For -1, it would be f(1)=\(8^{1} \).
Solve: \(8^{1} \) = 8
For -2, it would be f(2)=\(8^{2} \).
Solve: \(8^{2} \)
= 64 <- because 8*8=64

Answers
Answer:
Step-by-step explanation:
you are completely right please follow your heart <3
You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.
