Answer:

Equation: 28-F = N

then if he folded 22 it would be 6

Step-by-step explanation:

Im pretty sure thats right

Hope this helpsss!<3

Answer:

N = 28 - F     N = 6

Step-by-step explanation:

N = 28 - F

F = 22

28 - 22 = 6

N = 6

Answer:

B: 24 cm

Step-by-step explanation:

The triangle is ((4*3)/2). The squares are 12 (3*4) and 6 (1.5*4)

Answer:

24 cm^2

Step-by-step explanation:

We can find the area of the figure, surface area is for three dimensional figures

The area of the triangle is

A = 1/2 bh

A = 1/2 (3) *4 = 6

The area of the top rectangle is

A = l*w = 3 * (8-4) = 3* 4 = 12

And the area of the bottom rectangle

A = l*w = 1.5 ( 8-4) = 1.5*4 =6

The total area is the sum of the individual areas

6+12+6 = 24

24 cm^2

Answer:

$7000

Step-by-step explanation:

This problem seems scary at first sight, but don't be intimidated. It is actually pretty simple.

The column of equations (starting with 0.1d) at the right of T(d) is a list of option based on d, the taxable income. If d is less than or equal to (≤) 9875, than the equation is T(d) = 0.1d.

It shows that Noam has 90000 dollars for d, or the taxable income, and Betty has 120000 dollars.

Now, let's find the equations by plugging in 90,000 for d first.

90,000 is greater than 85, 526 and less than 163,300 (85, 526 ≤ 90,000 ≤ 163300).

Then we plug in 120,000 dollar to find the corresponding equation.

120000 is greater than 85, 526 and less than 163, 300 (85, 526 ≤ 120,000 ≤ 163300).

So the chosen equation is:  

T(d) = .24( d -85525) + 14605.5

Plug in the Noam's number for d

T(d) = .24(90,000 - 85, 525) + 14, 605.5

T(d) = .24(4475) + 14,605.5

T(d) = 1074 + 14,605.5

T(d) = 15, 679.5

Now Plug in Betty's number for d

T(d) = .24 (120,000 - 85, 525) +14, 605.5

T(d) = .24( 34475) + 14, 605.5

T(d) = 8274 + 14, 605.5

T(d) = 22, 879.5

We are finding how much more tax does Betty pay, so we subtract               15, 679.5 from 22, 879.5.

22, 879.5 - 15, 679.5 = 7200

Betty pays $7000 more tax than Noam does.

Answer:

(3, 1)

Step-by-step explanation:

We are given the following system:
4x + y = 13

x - 3y = 0

We want to find the solution.

We can solve this system with substitution, where we solve one of the variables for the other, then substitute that value into the other equation.

To start, we can add 3y to both sides to solve for x.

x - 3y = 0

 +3y    +3y

____________________

x = 3y

Now, substitute x as 3y in 4x + y = 13

4(3y) + y = 13

12y + y = 13

13y = 13

y = 1

Now, substitute 1 as y in x=3y

x = 3(1)

x = 3

Our solution is x = 3, y = 1. As a point, that is (3,1).

Answer:

10 minutes per mile

Step-by-step explanation:

Rasheem runs 1/5 miles in 2 minutes. What you need to do is find how many minutes it takes for 1 whole mile. To do this, you have to first see what you multiply to 1/5 to get to 1. As you know, you do 1/5 x 5/1 (or 5) to get to one. Since you did that 1/5, you also need to multiply 2 x 5, which is 10. This gives you the answer that Rasheem was running 10 minutes per mile.

Hope it helped! :)

Answer:

2

Step-by-step explanation:

the quotient is 2 because 814 can be decreased

Answer:

This is not a valid equation, as the left-hand side is not equal to the right-hand side.

Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

Step-by-step explanation:

The given equation is:

4 = u + at

where u = 17, a = 4, and t = 8.

Substituting the given values, we get:

4 = 17 + 4(8)

Simplifying the right-hand side:

4 = 17 + 32

Combining like terms:

4 = 49

This is not a valid equation, as the left-hand side is not equal to the right-hand side.

Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

Answer: Option C is the correct answer.

Step-by-step explanation:

The situation that best describes the relationship between all the values of x and y in the table is C. Belinda had six times as many markers as Peter had.

This is because the values of y are all multiples of 6, which is the value of x multiplied by 6. This indicates a proportional relationship between x and y, where y is always 6 times greater than x. This relationship is captured in the statement that Belinda had six times as many markers as Peter had, which shows a clear ratio between two quantities.

The other situations do not involve a proportional relationship between two quantities and do not capture the relationship between all the values of x and y in the table. Therefore, option C is the correct answer.

Step-by-step explanation:

Answer:

<

Step-by-step explanation:

89835000000*10^-7 = 8983.5

8.9835*10^5= 898350

8983.5 < 898350

Answer:

<

Step-by-step explanation:

Simplify each of the numbers

89835000000 x 10^-7 = 8983.5

8.9835 x 10^5 = 89835

89835000000 x 10^-7 < 8.9835 x 10^5

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Hello!

value                             29, 30, 35, 37, 42, 48, 51, 59, 63, 66, 68

effective                        2     1     1     1     1     1     1     1     1     1     1

cumulate effective       2     3     4    5    6    7    8    9    10   11   12

median:

12/2 = 6

The 6th cumulate effective corresponds to the value 42.

Answer:

40%

Step-by-step explanation:

If 60 out of 100 were oatmeal, 60% would be oatmeal.

20 lemon + 20 chocolate  = 40

40 out of 100 is 40%

To confirm add 60 and 40;

60+40=100

Answer: 40% were NOT oatmeal. ( i think)

Step-by-step explanation:

Sense there is 100, that makes it easy.

60% is oatmeal

20% is lemon

20% is chocolate

20 + 20 = 40

So its 40% were NOT oatmeal

I think that's right.
