What kind of transformation is it when it gets bigger? Like a small star to a bigger star.

Answer:

The correct answer is: Option D) 5

Step-by-step explanation:

Given equation is:

[tex]3(x + 2) + x = 2x + 16[/tex]

In order to find that which values of x makes the equation true, we have to put each value of x in the equation. When both sides of equations will be equal, that value of x will be true for the equation.

Putting x = 2

[tex]3(2 + 2) + 2 = 2(2) + 16\\3(4)+2 = 4+16\\12+2 = 20\\14 \neq 20[/tex]

Putting x = 3

[tex]3(3 + 2) + 3 = 2(3) + 16\\3(5)+3 = 6+16\\17+3 = 22\\20 \neq 22[/tex]

Putting x=4

[tex]3(4+2)+4 = 2(4)+16\\3(6)+4 = 8+16\\18+4 = 24\\22 \neq 24[/tex]

Putting x = 5

[tex]3(5+2)+5 = 2(5)+16\\3(7)+5 = 10+16\\21+5 = 26\\26 = 26[/tex]

The equation is true for x = 5

Hence,

The correct answer is: Option D) 5

Answer:

Korea = 15

Italy = 16

France = 17

Step-by-step explanation:

Let :

Korea = x

Italy = x + 1

France = x + 2

(since the values are consecutive)

x + x + 1 + x + 2 = 48

3x + 3 = 48

3x = 48 - 3

3x = 45

x = 45 / 3

x = 15

Korea = x = 15

Italy = x + 1 = 16

France = x + 2 = 17

Answer:

Its the first choice. Width:9 Length:13

Step-by-step explanation:

If the length is 4 meter more than the width than that means whatever the width is you must add 4 to it, in this case the width is 9 so add 4 to it which equals 13. If the length matches your answer it is the correct choice.

The area of a rectangle is the product of its dimensions. The dimension of the rectangle is: [tex]Length = 13m[/tex] and [tex]Width = 9m[/tex]

Given that:

[tex]L =4 + W[/tex]

[tex]Area = 117[/tex]

The area of a rectangle is:

[tex]Area = L \times W[/tex]

So, we have:

[tex]L \times W= 117[/tex]

Substitute [tex]L =4 + W[/tex]

[tex](4 + W) \times W = 117[/tex]

Expand

[tex]4W + W^2 = 117[/tex]

Rewrite as:

[tex]W^2 + 4W- 117 = 0[/tex]

Expand

[tex]W^2 + 13W - 9W - 117 = 0[/tex]

Factorize

[tex]W(W + 13) - 9(W + 13) = 0[/tex]

Factor out W + 13

[tex](W - 9)(W + 13) = 0[/tex]

Solve for W

[tex]W = 9[/tex] or [tex]W = -13[/tex]

The dimension cannot be negative.

So:

[tex]W = 9[/tex]

Recall that:

[tex]L =4 + W[/tex]

[tex]L = 4 + 9[/tex]

[tex]L = 13[/tex]

So, the dimension of the rectangle is:

[tex]Length = 13m[/tex]

[tex]Width = 9m[/tex]

Answer:

x = 28.1 (nearest tenth)

Step-by-step explanation:.since we are given two sides and an included angle, we would need to apply the Cosine Rule to find x. Thus,

x² = 18² + 14² - 2*18*14*Cos(122)

x² = 520 - (-267.079309)

x² = 520 + 267.079309

x² = 787.08 (approximated)

x = √787.08

x = 28.1 (nearest tenth)

Answer:

23.2 miles

Step-by-step explanation:

10 + 1.25x

x = number of miles

so if the total cost is $39, this is the equation:

10 + 1.25x = 39

Solve:

10 + 1.25x = 39

1.25x = 29

x = 23.2

So the answer will be 23.2 miles.

is the correct one out of the 4

Answer: The answer is 3 over 20.

Step-by-step explanation: On offer is 3 over 4 pizza.

Each person is given a slice that that is the same size as all the rest.

So the 3 over 4 pizza is split into 5 equally sized parts. Thus each of the 5 slices is 1 over 5 times 3 over 4 = 1x3 over 5x4 = 3 over 20 of a whole pizza.

Answer:

a) sin x

b) cos² x

c) sin²x

Step-by-step explanation:

Step(i):-

Given that the trigonometric equation

      [tex]tan(\frac{x}{2} ) + cos x tan (\frac{x}{2} ) = sin x[/tex]

we have to use trigonometric formulas

  [tex]1-cosx = 2sin^{2} (\frac{x}{2} )[/tex]

 [tex]sin x = 2 sin \frac{x}{2} cos\frac{x}{2}[/tex]

now

              [tex]tan\frac{x}{2} = \frac{sin\frac{x}{2} }{cos\frac{x}{2} }[/tex]

                       = [tex]\frac{2sin(\frac{x}{2} ) sin\frac{x}{2} )}{2sin\frac{x}{2} cos\frac{x}{2} }[/tex]

                       = [tex]\frac{2sin^{2} (\frac{x}{2} ) )}{sinx }[/tex]

                      = [tex]\frac{1-cosx}{sinx}[/tex]

Step(ii):-

[tex]tan(\frac{x}{2} ) + cos x tan (\frac{x}{2} ) = \frac{1-cosx}{sinx} +cosx \frac{1-cosx}{sinx}[/tex]

                                = [tex]\frac{1-cosx +cosx(1-cosx)}{sinx}[/tex]

                               = [tex]\frac{1-cosx+cosx-cos^{2} x}{sinx}[/tex]

                               = [tex]\frac{1-cos^{2} x}{sinx}[/tex]

                               = [tex]\frac{sin^{2}x }{sinx}[/tex]

                               = sinx

Answer:8

Step-by-step explanation answe is 8beuase the tree

a)The unit rate of ash tree is equal to 25.5 inches per year .(Table attached)   b) The magnolia tree grows by 16 inches every year.(Table attached)

c) Ash tree has the faster growth rate.

d) growth rate of ash tree = 1.77 mm

  growth rate of magnolia tree =1.113 mm

Double number line diagrams are best used when the quantities have different units.

Given here, the ash tree grows 51 inches over two years therefore unit rate of growth is 51/2 = 25.5 inches/year. Similarly, the magnolia tree grows 80 inches over five years thus the tree grows by 16 inches every year. Finally converting the growth rate of each tree in mm per day we get

growth rate of ash tree = 25.5 × 25.4 / 365

                                       = 1.77 mm

 growth rate of magnolia tree = 16 × 25.4 / 365

                                                  =1.113 mm

Hence, clearly ash tree grows faster than the magnolia tree and refer to the attachments for the table and double number line.

Answer: the percent value-added time for this ride is 16.67%

Step-by-step explanation:

 Given that;

Waiting time for Vera = 35 minutes

Length of Vera's ride = 7 minutes

total processed time will; ( 35 + 7 ) = 42 minutes

the percent value-added time for this ride = ?

so

Percentage value-added time of Vera will be

= (length of the ride / total process time) × 100

we substitute

⇒ (7 / 42) × 100

⇒ 0.16666 × 100

⇒ 16.67%

Therefore the percent value-added time for this ride is 16.67%

Answer:

z = 22

Step-by-step explanation:

Since this is a rhombus, we know that parallel sides are equal in length and that the angles should add to 360 degrees. The opposing angles, therefore, are also equal in size. So, you can find the answer by setting the two angles to each other.

3z = z + 44

2z = 44

z = 22

Answer:

z=22

Step-by-step explanation:

3z = z + 44

Answer:

B

Step-by-step explanation:

For three side lengths to make a triangle, the two smaller ones have to add up to be greater than the third one. This is because if they are any smaller, they won't be able to touch and form a triangle. The formula for this is a+b>c.

You can go through each answer choice and determine whether or not it would work:

A. 12, 5, and 7

5 + 7 > 12 --> 12 > 12 (NOT true)

B. 10, 15, and 24

10 + 15 > 24 --> 25 > 24 (true!)
