Answer:

D. (8.2, 24.3)

Answer:

This is really tilted, and I CANNOT see! But it looks like ratio, on one of the parts. Sorry, but I don't know!

Answer:

The equations 15 - n = 7, 4n = 32, and 64 : n = 8 have 8 as a solution.

Step-by-step explanation:

Each equation will have work shown below :

15 - n = 7

For this equation, we would need to isolate the variables by doing the inverse operation to both sides of the equation. Here in this equation, the operation is to subtract and the inverse operation of that is addition. Since the original operation is subtraction, we need to add it by a negative sign to each side. In order to isolate the variables, we have to add -7 to both sides.

  15 - n = 7

+ -7      + -7

   8 = n

The right side has a sum of 0 so it doesn't require any value to the equation. As you can see in the equation, n equals to 8.

4n = 32

For this equation, we would need to isolate the variables by doing the inverse operation to both sides of the equation. Here in this equation, the operation is to multiply and the inverse operation of that is division. In  order to isolate the variables, we have to divide 8 to both sides.

4n = 32

/4     /4

 n = 8

The left side has a quotient of 0 so it doesn't require any value to the equation. As you can see in the equation, n equals to 8.

This is a ratio which is basically just the operation of division. For this equation, we would need to isolate the variables by doing the inverse operation to both sides of the equation. Here in this equation, the operation is to divide and the inverse operation of that is multiplication. Since the original operation is division, we need to multiply it by the reciprocal to each side. In order to isolate the variables, we have to multiply 1/8 to both sides.

 64 : n = 8

* 1/8     * 1/8

  8 = n

The right side has a product of 0 so it doesn't require any value to the equation. As you can see in the equation, n equals to 8.

Answer:

[tex]y=x-3[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]y = -x+6[/tex]

Looking at the given line, we can identify clearly that -1 is in the place of m, making it the slope of the line. Because perpendicular lines have slopes that are negative reciprocals of each other, we know that the slope of the line we're solving for is 1. Plug this into [tex]y=mx+b[/tex]:

[tex]y=x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=x+b[/tex]

Plug in the given point (4,1)

[tex]1=4+b[/tex]

Subtract 4 from both sides

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

Therefore, the y-intercept is -3. Plug this back into [tex]y=x+b[/tex]:

[tex]y=x-3[/tex]

I hope this helps!

Answer:

150.8[tex]yd^3[/tex]

Step-by-step explanation:

I helped lol.

Have a nice day! :-)

Answer:

150.7

Step-by-step explanation:

Formula for volume of a cone = [tex]\pi r^2\frac{h}{3}[/tex]

where r = radius and h = height

We are given the diameter ( 8yds ) and the height ( 9yds )

In order to find the volume we need to find the radius

We can do this my dividing the diameter by 2 ( this is because the radius is equal to half the length of the diameter)

8/2 =4

So the radius is equal to 4yds

Now we plug in the values into the formula

( remember it says use 3.14 for π )

[tex]V=(3.14)4^2\frac{9}{3} \\4^2=16\\16*3.14=50.24\\\frac{9}{3} =3\\3*50.24=150.72[/tex]

Finally we round to the nearest tenth and get that the answer is 150.7yd²

Answer:

x=4

Step-by-step explanation:

The y axis is a line where the value of x does not change ( x=0)

It is a vertical line

The only line where the value of x does not change is x=4

It is a vertical line at x=4

Answer:

x = 15

Answer:

(A)  120 cm³

(B) 184 cm²

Step-by-step explanation:

(A)

Assuming the diagram attached is thesame as the one needed to complete the question,

Applying

V = A'×L................... Equation 1

Where V = volume of the prism, A' = Area of the triangular base, L = Length of the prism.

But,

A' = 1/2bh............. Equation 2

Where b = base of the triangle, h = height of the triangle.

Substitute equation 2 into equation 1

V = 1/2bh(L)............... Equation 3

From the question,

Given: b = 6 cm, h = 4 cm, L = 10 cm

Substitute these values into equation 3

V = 1/2(6×4×10)

V = 120 cm³

(B)

Surface area of the prism(A) = bh+L(a+b+c).............. Equation 4

Given: b = 6 cm, b = 5 cm, c = 5 cm, L = 10 cm, h = 4 cm

Substitute these values into equation 4

A = (6×4)+10(5+5+6)

A = 24+160

A = 184 cm²

Answer:

Step-by-step explanation:

Equation

The volume formula is

V = L * W * H

Givens

From the diagram

L = 6 mi

W = 2 mi

H = 5  mi

Solution

V = 6 * 5 * 2

V = 60 cubic miles

Note: Consider we need to find the factor form of the given expression by taking out the GCF.

Given:

The expression is:

[tex]-42k^3+24k^4+12k^5[/tex]

To find:

The factor form of the given expression.

Solution:

We have,

[tex]-42k^3+24k^4+12k^5[/tex]

It can be written as:

[tex]=6k^3(-7)+6k^3(4k)+6k^3(2k^2)[/tex]

Taking out the greatest common factor (GCF), we get

[tex]=6k^3(-7+4k+2k^2)[/tex]

Therefore, the factor form of the given expression is [tex]6k^3(-7+4k+2k^2)[/tex].
