Answer:

A: The scale is 40. (not sure how you word it, the drawing is 40 times smaller)

B: 60 inches.

C: 200 ft.

Step-by-step explanation:

A: if the hight is 9 inches in the drawing, and 30 ft in real life, you can change the ft in to inches. ( 30 x 12) and divide that by 9 to find how much different the size is from the drawing to real life. This will give you the equation 360 divided by 9. Thus the answer is 40.

B: Just solving perimeter. L + L + W + W. In this case, (21 + 21 + 9 + 9 = 60)

C: As determined previously, the drawing is 40 times smaller than the real screen so the drawing times 40 will give the real thing in inches. To make this simpler you can change the 60 inches to 5 feet. The equation would be (5 x 40) The answer being 200.

For this case we have that by definition, the perimeter of the quadrilateral shown is given by the sum of its sides:

Let "p" be the perimeter of the quadrilateral, then:

p = 7 + y + 7 + x\\p = 7 + 7 + x + y\\p = 14 + x + y

So, the perimeter of the figure is: 14 + x + y

Answer:

p = 14 + x + y

Drag each real-world situation to the correct column to show whether it can be modeled by combining additive inverses to get 0.
Flauer [41]

Answer:

. An investment account earns 2.8% simple interest.

   Since investment amount increases every year linearly, therefore, the modeled situation represents a LINEAR FUNCTION.

B). The price of a stock varies by 2.8% each week.

   Since price of the stock may increase or decrease every week, therefore, this situation can't be modeled by any function.

Therefore, the answer is NEITHER.

C). An investment account earns 2.8% compound interest, compounded monthly.

Formula to get the value of the final amount in the account is,

Final value = Initial value ×

Here 't' = Duration of investment

It's an EXPONENTIAL FUNCTION.

Simplify.<br> 8√2 / 6-3√8
Sonbull [250]

 The rationalized expression in general term is given by: (-8 -4√2) / 3

<h3>What is rationalization?</h3>

  Rationalization is a mathematical operation that allows us to determine or eliminate a root of the denominator of a fraction, so that it can be expressed in linear form, either decimal or integer, by the product of a root.

  As defined above, we must perform a mathematical operation to eliminate the root of the denominator without altering the value.

(8√2 / 6-3√8 ) Multiply by  ( 6+3√8)/( 6+3√8)

(8√2 / 6-3√8 )( 6+3√8)/( 6+3√8)

8√2(6+3√8) / (6-3√8)²  Expand the denominator using the FOIL method.

8√2(6+3√8) / (36 - 18√8 + 18√8 - 72)

8√2(6+3√8) / -36

48√2 + 24√2√8 / -36  ::::.   √8 = 2√2

48√2 + 96 / -36

-12(4√2 + 8) / 12x3

(-8 -4√2) / 3 is the result.
