Answer:

Answer:

The ratio of the area in the drawing to the actual area is 1 square centimeter:4 square feet.

Step-by-step explanation:

Find the number of feet represented by 1 centimeter in the scale drawing.

1 cm

2 ft

1 centimeter in the drawing equals 2 feet on the actual floor.

Step 2:

Find the side length of the floor in the scale drawing.

The area of the square in the drawing is 64 square centimeters, so the side length must be 8 cm.

Step 3:

Find the side length of the actual floor represented by 8 cm in the scale model.

1 cm × 8

2 ft × 8

=

8 cm

16 ft

The side length of the actual floor is 16 ft.

Step 4:

Since the area of a square is the side length squared, the area of the actual floor is 256 square feet.

Step 5:

The ratio of the area in the drawing to the actual area is 64 square centimeters:256 square feet.

Simplify the ratio.

The ratio of the area in the drawing to the actual area is 1 square centimeter:4 square feet.

Devon studied the composite figure.(Picture 1)
He believed the surface area, in square units, could be found by simplifying the expression
(Picture 2)
What error did Devon make?

A. He used 26 instead of 24 as the slant height of one set of lateral faces.
B. He omitted the rectangle where the upper and lower solids join together.
C. He included the 34 by 20 base of the figure.
D. He believed the upper part of the figure was a pyramid instead of a prism.

Answers

If we look at his calculations
2((9)(20) is the front an back rectangle
2((9)(34)) is the side rectangles
(34)(20) is the bottom

Multiply the binomials (3x - 5) and (4x + 6).

Answers

Answer:

12x² - 2x - 30

Step-by-step explanation:

When multiplying binomials, remember to follow the FOIL method:

FOIL =

First

Outside

Inside

Last

Follow FOIL: (3x - 5)(4x + 6)

(3x)(4x) = 12x²

(3x)(6) = 18x

(-5)(4x) = -20x

(-5)(6) = -30

Combine like terms, simplify:

12x² + 18x - 20x - 30

12x² + (18x - 20x) - 30

12x² - 2x - 30

12x² - 2x - 30 is your answer.

Answer:

12x²-2x-30=2(6x²-x-15)

Step-by-step explanation:

12x²-2x-30=2(6x²-x-15)

a hockey season ticket holder pays $72.48 for her tickets plus $6.00 for a program each game. A second person pays $18.08 for a ticket to every game, but doesn't buy programs. In how many games will they have paid the same amount?

Answers

If I understand the question correct, the hockey season ticket holder paid $72.48 for all of the tickets at once, and then $6.00 for each game thereafter. The second person pays $18.08 for a ticket per game.

So then let g = the number of games. The problem can be written as a system of equations:

Person 1 = 72.48 + 6g
Person 2 = 18.08g

We are looking for when the number of games for both are the same. To do this, just set them equal to each other and solve for g.

72.48 + 6g = 18.08g
Subtract 6g:
72.48 = 12.08g
Divide by 12.08:
g = 6

So after 6 games, the two would have paid the same price.
