<span>First we,Find the other side of the bed!

Which would be 60 since 4800/80(the other side) would give us 60

now we take 80 and divide it by 12 ( since the dimension is 1/12) to get 6.667

now we do the same for the 60 ( the other side that we found above)
so 60/12 would equal 5

 So now we multiply the two new found numbers (5 and 6.6667)
 5 * 6 = 30

So your answer would be 30 Inches squared.... I hope that this helps you!!
 I got 20 by 20 equals 400 inches squared so the sides would be 20 message me for more!

Divid to get the other side :) so if the doll house is 1/12 of the queen size bed you divid each side by 12 see. 4800/80=60. 80/12=6.6667.... so 60/12=5. so then 5x6 1/3. hope this helps you ... goood luck! :)

NeTakaya

Answer:

a) - Compressing the P(new) function by a scale of 0.5 about the y axis.

- Moving the P(new) function down by 104 units.

b) The two simplified functions for P(original)

-0.08x² + 10.8x – 200.

-0.16x² + 21.6x – 504.

Step-by-step explanation:

Complete Question

An electronics manufacturer recently created a new version of a popular device. It also created this function to represent the profit, P(x), in tens of thousands of dollars, that the company will earn based on manufacturing x thousand devices: P(x) = -0.16x² + 21.6x – 400.

a. The profit function for the first version of the device was very similar to the profit function for the new version. As a matter of fact, the profit function for the first version is a transformation of the profit function for the new version. For the value x = 40, the original profit function is half the size of the new profit function. Write two function transformations in terms of P(x) that could represent the original profit function.

b. Write the two possible functions from part a in simplified form.

Solution

The equation for the new profit function is

P(x) = -0.16x² + 21.6x – 400

At x = 40, the original profit function is half the size of the new profit function

First, we find the value of the new profit function at x = 40

P(x) = -0.16(40)² + 21.6(40) – 400 = 208

Half of 208 = 0.5 × 208 = 104

P(original at x = 40) = P(new at x = 40) ÷ 2

Since we are told that P(original) is a simple transformation of the P(new)

P(original) = P(new)/2 = (-0.16x² + 21.6x – 400)/2 = -0.08x² + 10.8x – 200 ... (eqn 1)

Or, P(original) = 104

-0.16x² + 21.6x – 400 = 104

P(original) = -0.16x² + 21.6x – 400 - 104 = -0.16x² + 21.6x – 504.

So, the two functions that are simple transformations of P(new) to get P(original) are

-0.08x² + 10.8x – 200

Obtained by compressing the P(new) function by a scale of 0.5 about the y axis.

And

-0.16x² + 21.6x – 504.

Obtained by moving the P(new) function down by 104 units.

Hope this Helps!!!

An artist uses a 3 foot piece of wood to carve statues. She uses 1/6 foot pieces of wood for each statue. How many statues can b
bixtya [17]

Answer:

D- 18

Step-by-step explanation:

We simply need to divide the amount of wood she has by amount of wood that she needs for each statue.

She uses a 3 foot piece of wood and she needs 1/6 foot of wood for each statue.

Therefore, the number of statues she can make is:

\frac{3}{\frac{1}{6} } = 3 * 6 = 18

She can make 18 statues.
