Answer:

12

Step-by-step explanation:

Use cross-multiplication method:

If 2.25 is 27, 1 is x.

So divide 27 by 2.25 which gives 12.

Answer:

12

Step-by-step explanation:

Let x be the number we are looking for. Using informations in the task, we get following equation which we suppose to solve for x

2\frac{1}{4} x=27

Now, we will write mixed number as a fraction and get

\frac{9}{4} x=27

In the next step, we will multiply both sides of the equation by 4 and get

9x=27*4\\x=\frac{27*4} {9}\\x=12

So, required number is 12.

The transformed equation y = -(x - 2)^2 - 3 compared to the parent function involves  translating the parent function to the right by 2 units, reflecting the function across the y-axis and translating the function 3 units down

<h3>How to compare the function to its parent function?</h3>

The equation of the transformed function is given as:

y = -(x - 2)^2 - 3

While the equation of the parent function is given as

y = x^2

Start by translating the parent function to the right by 2 units.

This is represented as:

(x, y) = (x - 2, y)

So, we have:

y = (x - 2)^2

Next, reflect the above function across the y-axis

This is represented as:

(x, y) = (-x, y)

So, we have:

y = -(x - 2)^2

Lastly, translate the above function 3 units down

This is represented as:

(x, y) = (x, y - 3)

So, we have:

y = -(x - 2)^2 - 3

Hence, the transformed equation y = -(x - 2)^2 - 3 compared to the parent function involves  translating the parent function to the right by 2 units, reflecting the function across the y-axis and translating the function 3 units down

A custodian plans to repaint some classrooms. He has 5 = gallons of paint. All of
dlinn [17]

Answer: 2 bookcases.

Step-by-step explanation:

Let be "x" the number of bookcases that the custodian will be able to repaint completly with 5 gallons of paint.

According to the data given, the custodian needs 2 gallons of paint to repaint one bookcase. Since all the bookcases are equal, you can set up the following proportion:

\frac{2}{1}=\frac{5}{x}

Now you must solve for "x" in order to find its value:

(x)(\frac{2}{1})=5\\\\2x=5\\\\x=\frac{5}{2}\\\\x=2.5

Notice that the custodian will be able to repaint 2 bookcases completely, then you can say that:

x\approx2
