Answer would be <u>72yd</u>.  Multiply 12x3 to get 36.  Subtract the 12x3 part of the polygon to get another 6x6 part.  Add the values together [(12x3) + (6x6)] to get 72.

Hope this helped! If it did, would you mind marking this answer as Brainliest? Thanks :D

Describe the transformation that takes f(x)=x+1 to g(x) = -x+4. Will Mark Brainliest.​
lions [1.4K]

Answer:

Reflection across y axis

Translate up by 3 units

Step-by-step explanation:

Given

f(x) = x + 1

g(x) = -x + 4

Required

Describe the transformation from f(x) to g(x)

First, take a reflection of f(x) across the y axis.

So f(x) becomes f(-x)

f(x) = x + 1 when reflected

f(-x) = -x +1

Next, translate f(-x) up by 3 units to give g(x)

g(x) = f(-x) + k

Where

k = 3

f(-x) = -x +1

g(x) = -x + 1 + 3

g(x) = -x + 4

Hence, the transformation from f(x) to g(x) includes:

Reflection across y axis

Translate up by 3 units

The length of a table is 8 times longer then it’s width. If the perimeter is 72, how wide is the table?
Andrews [41]

Answer:

4 units wide

Step-by-step explanation:

Let the width of the table be 'w'

Given:

Perimeter of the table is, P=72

The perimeter of the rectangular table is given as the sum of all the sides of the rectangle. The sides include two lengths and two widths.

Length of the table is 8 times longer than its width. Therefore,

Length,L=8w

Now, perimeter is given as:

P=2L +2w\\P=2(8w)+2w\\P=16w+2w\\P=18w\\w=\frac{P}{18}

Now, plug in 72 for 'P' and solve for 'w'. This gives,

w=\frac{P}{18}\\\\w=\frac{72}{18}\\\\w=4

So, the table is 4 units wide.

deff fn [24]

12 girls out of 30 were selected, so the ratio "selected:tried" if 12/30. This fraction can be simplified into

\dfrac{12}{30} = \dfrac{2}{5}

Similarly, 16 boys out of 40 were selected, so the ratio "selected:tried" if 16/40. This fraction can be simplified into

\dfrac{16}{40} = \dfrac{2}{5}

So yes, the ratio of the number of students on the team to the number of students trying out the same for both boys and girls
