John is building his daughter a doll house that is a miniature model of their house. The front of their house has a circular win
n200080 [17]

Answer:

see the procedure

Step-by-step explanation:

we know that

The scale factor of the model is 1/30

That means ----> 1 unit in the model represent 30 units in the actual

so

using proportion

Find out how much represent 5 ft in the model

Convert feet to inches

Remember that

1\ ft=12\ in

so

5\ ft=5(12)=60\ in

Let

x -----> the diameter of the circular window in the model house in inches

\frac{1}{30}=\frac{x}{60}\\\\x=\frac{60}{30}\ in

Simplify

2\ in

therefore

The diameter of the circular window in the model house is 2 inches

see the attached figure to better understand the problem

Find the difference.
MrMuchimi

To find the difference of the given expression, first step is to get rid of parenthesis. So, distribute negative sign to each terms of the second parenthesis. Hence,

(9x² + 10x + 4) - (9x² + 5x - 1)

= 9x² + 10x + 4 - 9x² - 5x + 1.

= (9x² - 9x²) +(10x - 5x) + (4 + 1) Group the like terms.

= 0 + 5x + 5 Combine the like terms.

= 5x + 5.

So, first choice is correct.

Hope this helps you!
