A. n = 12

B. n = -12

C. n = -3

D. n = 3

Solve A. N = 12B. N = -12C. N = -3D. N = 3

Answers

Answer 1

Answer:

n/3+2 =-2

n+6=-6

n=-12 is your answer

Answer 2

Answer:

B

Step-by-step explanation:

Given

[tex]\frac{n}{3}[/tex] + 2 = - 2 ( subtract 2 from both sides )

[tex]\frac{n}{3}[/tex] = - 4 ( multiply both sides by 3 to clear the fraction )

n = - 12 → B

A cylinder has a height of 11 inches. Its volume is 4,973.76 cubic inches. What is the radius of the cylinder?

Use ​ ≈ 3.14 and round your answer to the nearest hundredth.

Answers

Answer:

12 inches

Step-by-step explanation:

Given data

Height= 11 inces

Volume=  4,973.76 cubic inches.

The expression for the volume of a cylinder is

V= πr^2h

substitute

4,973.76= 3.14*r^2*11

4,973.76= 34.54r^2

r^2= 4,973.76/ 34.54

r^2= 144

Square root both sides

r=√144

r=12 inches

What is the equation of the line that passes through point Q and is parallel to line P?​

Answers

Answer:

[tex]y=\frac{3}{2} x+1[/tex]

Step-by-step explanation:

What we need to know:

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slope (m) and different y-intercepts (b)

1) Find the slope of line P

The slope of a line is equal to the [tex]\frac{rise}{run}[/tex], or the number of units the line moves up over the number of units the line moves to the right.

We can see that for line P, for every 2 units it moves to the right, it moves up 3 units.

Therefore, the slope of line P is [tex]\frac{3}{2}[/tex].

Knowing this, the equation of a line parallel to line P would have a slope of [tex]\frac{3}{2}[/tex] as well. Plug this into [tex]y=mx+b[/tex] as m:

[tex]y=\frac{3}{2} x+b[/tex]

2) Plug the given point Q into [tex]y=\frac{3}{2} x+b[/tex]  to find the y-intercept (b)

[tex]y=\frac{3}{2} x+b[/tex]

Plug in point Q (2,4)

[tex]4=\frac{3}{2} (2)+b\\4=\frac{6}{2}+b\\4=3+b[/tex]

Subtract 3 from both sides

[tex]4-3=3+b-3\\1=b[/tex]

Therefore, the y-intercept of this line (b) is 1. Plug this back into our original equation:

[tex]y=\frac{3}{2} x+b[/tex]

[tex]y=\frac{3}{2} x+1[/tex]

Mario was shopping for a new camera. He found one with an original price of $125.00 and is marked 45% off. Sale tax for the item is 5.2%. What is the final price of the camera, including tax?

Answers

Answer:

72.33

Step-by-step explanation:

45 percent of 125 is 56.25 so you subtract that from 125 and get 68.75 and then you do 5.2 percent of 68.75 and get 3.575 which rounds to 3.58 and you add that to 68.75 and get 72.33

The two figures are similar. Complete sentences
a) Write the similarity statement.
b) Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
c) What is the scale factor? Explain

Answers

Answer:

a)ABC ≅ A'B'C' (SSS) b) Enlargement c) Scale factor = 4

Step-by-step explanation:

a) ABC ≅ A'B'C' (SSS)

b) The figure is going through an enlargement, this is evident as the figures have a scale factor of 4. If we were to put them into a fraction like this -

6/24=12/48=15/60

The figures are getting bigger, so they are going through an enlargement.

c) To find the scale factor of like done above, we could put them into a ratio.

6/24=12/48=15/60

Which would result in the scale factor of 4.

How to find the missing dimensions of a prism

Answers

Answer:

Below.

Step-by-step explanation:

You need to know the volume or total surface area of the prism and 2 of the dimensions.

The formula for the volume = wlh   where w = width , l = length and h = height.

So knowing say w = 4, l = 8 and V =  192 we have:

V = wlh

192 = 4 * 8 * h

h = 192/4*8

= 192/32

= 6.

Step-by-step explanation:

Answer:

D. $52293.03

Step-by-step explanation:

Initial values

Net worth is $45765.78Assets $62784.14

Liabilities:

$62784.14 - 45765.78 = $17018.36

New values

Assets increase:

$62784.14 + $2784.89 = $65569.03

Liabilities decrease:

$17018.36 - $3742.36 = $13276

His net worth:

$65569.03 - $13276 = $52293.03

If p and q vary inversely and p is 26 when q is 9, determine q when p is equal to 18.

Answers

Answer:

q = 13

Step-by-step explanation:

p and q vary inversely:

p = k/q

If p = 26, q = 9, find k:

26 = k/9k = 26*9 = 234

The equation is:

p = 234/q

When p = 18, q is:

18 = 234/qq = 234/18q = 13

What happens to the area of a circle if the circumference is doubled?
A. The area is 1/2 of the original circle
B. The area is the same as the original circle
C. The area is 2 times the original circle
D. The area is 4 times the original circle
E. The area is 8 times the original circle

Answers

Answer:

D. The area is 4 times the original circle

Step-by-step explanation:

The circumference:

C = 2πr

If the circumference is doubled, it means the radius is doubled.

The area:

A = πr²

And the new area:

A1 = π(2r)² = 4πr² = 4A

Correct choice is D

Answer:

Solution given:

area of a circle[A]=πr²

circumference of circle [C]=2πr

when circumference of circle is doubled

it becomes :4πr

Step-by-step explanation:

area directly proportional to circumference

πr²=2πr

when circumference is doubled

πr²=2(2πr)

so area

C. The area is 2 times the original circle

Answers

Answer:

A translation of 3 units to the right and a translation of one unit upwards.

Step-by-step explanation:

When we analyze translations of whole figures, all the points in the figure suffer the same translation, then we only need to analyze the translation of one of the points.

This means that we can only see the translation from A to A'

First, let's find the coordinates of each point:

A (2, 3)

A' (5, 4)

The translation is given if we calculate the difference between these coordinates:

A' - A =  (5, 4) - (2, 3) = (5 - 2, 4 - 3) = (3, 1)

The change in the x-value is 3.

The change in the y-value is 1.

Then we can conclude that:

A' is 3 units at the right of A

A' is 1 unit above A.

Then the translation is:

A translation of 3 units to the right and a translation of one unit upwards.

When the y coordinate is positive, which way do you move on the coordinate plane?
