An artist is making a scale model of a statue. On the model 2 inches represent 1 foot on the actual state witch graph best represents this relationship

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

[tex]7\times{(4+x)}=42[/tex]

Divide both sides by 7:

[tex]4+x=42\div{7}\\4+x=6[/tex]

Subtract 4 from both sides:

[tex]x=6-4\\x=2[/tex]

Answer:

1080°

Step-by-step explanation:

sum = 180 ( n - 2)

note that octagon has 8 sides

therefore

sum = 180 ( 8 - 2)

sum = 1080°

Answer:

c.  1080

Step-by-step explanation:

= 180 x ( 8 - 2)

= 1080

Answer: -31

Step-by-step explanation: 1.) Plug in -6 for c

2.) equation will then be: 6(-6)+5

3.) use PEMDAS: multiply first then addition

4.) 6(-6) equals -36

5.) add -36+5 which equal -31

Therefore your answer should be -31

Answer:

Ok, when we have a point (x, y) and we do a rotation of 90° the new points will actually depend on the quadrant where we are, but it will always change the order to (y, x) but this does not end here, because depending on the quadrant where the point ends, the signs will change as follows.

1st quad (+y, +x)

2nd quad (-y, +x)

3rd quad (-y, -x)

4th quad (+y, -x)

So if we are in the second quadrant, the transformed point will be in the first quadrant

Now, we have that the points G and H are:

G = (-1, 3)

This point is in the second quadrant, so it moves to the first quadrant (where bot values must be positive).

The new point will be:

G´ = (3, 1)

And the other point is:

H = (-4, 0)

It also rotates to the first quadrant, so the new point will be:

H' = (0, 4)

Answer:

Because the person above already explained I’ll just give the answers.

Step-by-step explanation:

G = (-1,3) H = (-4,0) I = (3,-2)

Question:

A carpenter sands 1/2 of a dresser in 3/4 hour. At this rate, how long does it take the carpenter to sand 1 dresser?

Answer:

[tex]1\ dresser = \frac{3}{2} hour[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2} dresser = \frac{3}{4} hour[/tex]

Required

How long will it take to sand 1 dresser

[tex]\frac{1}{2} dresser = \frac{3}{4} hour[/tex]

Multiply both sides by 2

[tex]2 * \frac{1}{2} dresser = \frac{3}{4} hour * 2[/tex]

[tex]1\ dresser = \frac{3}{4} hour * 2[/tex]

[tex]1\ dresser = \frac{3}{2} hour[/tex]

Hence;

It'll take 3/2 hour to sand 1 dresser

Answer:

3.34, 3 1/3 300%

Answer: T = 22,000 - 1,900n

Step-by-step explanation:

Taxable value is $22,000

The tax code allows for the depreciation of this van by $1,900 per year.

After n years therefore the total depreciation is;

= 1,900 * n

This depreciation will need to be removed from the taxable value of $22,000 to find out the taxable value left.

Formula is therefore;

T = 22,000 - 1,900n

Answer:

31 hours 57 minutes.

In most jobs, the employees round up so that would make it 32 hours.

32x7.50= 240

If they wanted to be technical you could do 31.57x7.5 and that would make it 236.78

It’s up to you which one you go with

Step-by-step explanation:

The ratio from miles traveled to miles to go is 1:-1

520-0=520

520-100=420

520-200=320

520-350=170

520-520=0

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

this problem is on the mensuration of solids shapes.

first we need to calculate the volume of the rectangular prism

volume of prsim= l*b*h

given that

length= 1.5 in

breath=2.5 in

hieght= 6 in

volume= 1.5*2.5*6

volume=22.5 in^3

secondly we then calculate the volume of a malt ball

given that

raduis r= 0.34

volume of sphere = 4/3πr^3

volume of sphere = 4/3*3.124*(0.34)^3

volume of sphere = 1.33*3.142*0.039

volume of sphere = 0.16 in^3

now we can calculate the amount of sphere that can fit into the prism as

= volume of prism/volume of sphere

= 22.5/0.16

=140.6

approximately 141 malt balls

1/a^3 and 1/b^5

Answer:

The  value is  [tex]v(3) =  29.4 \  m/s[/tex]

Step-by-step explanation:

From the question we are told that

    [tex]s(t) =  -4.9t^2 + 500[/tex]

And  

    [tex]\lim_{t \to a}  \frac{s(a) - s(t)}{a-t}[/tex]

Generally s(t) at t = a is mathematically evaluated as

      [tex]s(a) =  -4.9a^2+ 500[/tex]

So

    [tex]s(a) - s(t) =  -4.9a^2 + 500 - ( -4.9t^2+500)[/tex]

     [tex]s(a) - s(t) =  -4.9a^2 + 500 +4.9t^2-500)[/tex]

      [tex]s(a) - s(t) = 4.9(t^2 - a^2)[/tex]

Thus the velocity is represented as

     [tex]v(t) =\lim_{t \to a}  \frac{s(a) - s(t)}{a-t} \equiv \lim_{t \to a} \frac{4.9(t^2 -  a^2 )}{ a-t}[/tex]

=>     [tex]v(t) = \lim_{t \to a}  - 4.9(a + t )[/tex]

=>      [tex]v(t) = -4.9 (a + a )[/tex]

=>      [tex]v(t) = -9.8a[/tex]

Now at  t =  3

=>  [tex]v(3) = -9.8 (3)[/tex]

=>   [tex]v(3) =  29.4 \  m/s[/tex]

Answer:

Always true

Step-by-step explanation:

Given

[tex]\frac{2}{3}x + 4 = 2x[/tex]

Required

Determine its type of solution

[tex]\frac{2}{3}x + 4 = 2x[/tex]

Collect Like Terms

[tex]2x - \frac{2}{3}x = 4[/tex]

Take LCM

[tex]\frac{6x - 2x}{3} = 4[/tex]

[tex]\frac{4x}{3} = 4[/tex]

Multiply both sides by [tex]\frac{3}{4}[/tex]

[tex]\frac{4x}{3} * \frac{3}{4}= 4 * \frac{3}{4}[/tex]

[tex]x = 4 * \frac{3}{4}[/tex]

[tex]x = 3[/tex]

Hence, the equation is always true for x = 3

Answer:

[tex]\frac{1}{w^{29}}[/tex]

Step-by-step explanation:

The given expression is [tex]\frac{w^{-7}(w^{-9})^2}{w^4}[/tex].

Since, [tex]w^{-7}=\frac{1}{w^7}[/tex]

And [tex]w^{9}=\frac{1}{w^9}[/tex]

Expression will become,

[tex]\frac{w^{-7}(w^{-9})^2}{w^4}=\frac{\frac{1}{w^7}(\frac{1}{w^9})^2}{w^4}[/tex]

               [tex]=\frac{\frac{1}{w^7\times w^{18}}}{w^4}[/tex]

               [tex]=\frac{\frac{1}{w^{(7+18)}}}{w^4}[/tex]

               [tex]=\frac{1}{w^{25}}\times \frac{1}{w^4}[/tex]

               [tex]=\frac{1}{w^{25}\times w^4}[/tex]

               [tex]=\frac{1}{w^{29}}[/tex]

Therefore, Simplified form of the given expression will be [tex]\frac{1}{w^{29}}[/tex].
