#12) Mara had 5 inches of ribbon. How long is this in centimeters?

Answer:

Student C is correct.

Students A and B do not account for the variable in the equation. Student A assumes that it has already been 10 months when it has not been stated in the question. Student B has come to the conclusion that it has been 11 months. Neither have an equation to show for it. Student D is incorrect because the variable "m" equals the number of months, and the number of months would not equal the amount of money Walter would be receiving in total. Student C is correct because the variable "m", or months, is being multiplied by 200, or the amount of money.

For example, if 5 months were to pass, then you would receive 1000 dollars, because 5×200 is 1000. This would hold up, as in the original problem, you receive 200 dollars per month. another example is if you replace "m" with 0, then it will show that in 0 months, you will have 0 dollars, and it is stated at the beginning of the problem that Walter's bank account starts at $0.

Answer:

36%

Step-by-step explanation:

54/150 is a 36%

Answer:64%

Step-by-step explanation:

Answer:

x<100

Step-by-step explanation:

The given equation is :

x-19<81

Adding 19 to both sides of the equation.

x-19+19<81+19

x<100

It means the solution of the given equation is less than 100. Hence, the attached figure shows the graph for the given equation.

Answer:

43

Step-by-step explanation:

[tex]3^{3}[/tex]+[tex]4^{2}[/tex]=

Solve:

[tex]3^{3}[/tex]= 3*3*3= 9*3= 27

[tex]4^{2}[/tex]= 4*4= 16

Then add them together:

27+16= 43

Hope this helps!

Answer:

x = 4/5

Step-by-step explanation:

3(x-4)=12x

3x-12=12x

3x+12x-12=12x-12x

15x-12=0

15x-12+12=0+12

15x=12

15x/15=12/15

x = 4/5

hope it's helpful ❤❤❤❤

Answer: A

Step-by-step explanation:

Since multiplication is the only operation under the radical, you can apply the root to each term. Im not sure if I worded that correctly, but ill hopefully explain correctly.

First we need to take the cubed root of 648. This number doesn't have a perfect root, but it can be simplified. 648 is the same as 216*3, and 216 has a perfect cubed root of 6. So we can bring the 6 outside of the radical

[tex]3x*6\sqrt[3]{3x^4y^8}=18x\sqrt[3]{3x^4y^8}[/tex]

The next step is simplifying the variables, which is the easiest part. Just split them up into multiples of 3, again poor explanation but Ill show what I mean.

[tex]18x\sqrt[3]{3x^3xy^3y^3y^2}[/tex]

The cubed root and the cubed power will cancel and can be brought outside the radical[tex]18x*xy^2\sqrt[3]{2xy^2} =18x^2y^2\sqrt[3]{3xy^2}[/tex]

Answer:

The equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4

Step-by-step explanation:

As given,

The backward is rectangular in shape

Also , we know that

Area of rectangle = 2 ( Length + Breadth )

Also, given,

Breadth of the backyard = 5.2 + Length of the backyard

Let

length of the backyard = l

Breadth of the backyard = w

∴ we get

w = 5.2 + l

⇒l = w - 5.2

and

Area = 2 ( l + w)

⇒51 = 2( w - 5.2 + w)

⇒51 = 2 ( 2w - 5.2)

⇒51 = 4w - 10.4

So, the equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4

By solving we get

4w = 51 + 10.4

⇒4w = 61.4

⇒w = [tex]\frac{61.4}{4}[/tex] = 15.35

⇒ w = 15.35

⇒ l = w - 5.2 = 15.35 - 5.2 = 10.15

⇒l = 10.15

So the dimensions of the backyard = l × b = 10.15 m × 15.35 m

Answer: 8000 plz mark brainliest

Step-by-step explanation: 72/18 =4 (therefore it doubles 4 times as shown below)

Answer:

p = - 8

Step-by-step explanation:

3 (p - 1) = 2p - 11

3p - 3 = 2p - 11

3p - 2p = -11 + 3

p = -8

Answer:

p = - 8

Step-by-step explanation:

Given

3(p - 1) = 2p - 11 ← distribute parenthesis on left side

3p - 3 = 2p - 11 ( subtract 2p from both sides )

p - 3 = - 11 ( add 3 to both sides )

p = - 8

Step-by-step explanation:

Answer:

$29.25

Step-by-step explanation:

The formula for amount of interest is the P*R*T. Because the principal is $650 dollars, and the rate is 4.5% for 1 year, the formula so far is 650*0.045*T. The interest is per annum or annual, so the time has to be in terms of years, which in this case is 1 year. This would give you 650*0.045. The answer for that is simply $29.25.
