19. The areas of corresponding faces of two similar hexagonal prisms are 25 cm² and 121 cm². What is the ratios of the correspon
Pie

ANSWER

I) 5:11

ii) 5:11

iii) 125:1331

EXPLANATION

Let the side lengths be in the ratio:

x:y

This implies that the area will be in the ratio:

\frac{ {x}^{2} }{ {y}^{2} }  =  \frac{25}{121}

Take positive square root.

\frac{x}{y}  =  \sqrt{ \frac{25}{121} }

\frac{x}{y}  =  \frac{5}{11}

Hence the sides are in the ratio:

x:y=5:11

The perimeter of the smaller hexagon is 6×5=30

The perimeter of the larger hexagon is 6×11=66

The ratio of the perimeter is

30:66=5:11

The volume will be in the ratio

5³:11³

125:1331

Write an Algebraic Expression for Problems 1 - 6.
DIA [1.3K]

Answer:

I'm gonna rewrite each sentence in a way that lines up a little more with the Algebraic expression you would end up with. Just keep in mind that either way of saying it is correct.

1. "8 times some number (a variable) minus 5"

8x-5

2. "13 plus some number"

13+x

3. "Some number over 7"

x/7 or x÷7

4. "d number of drinks times 3.50 plus 12 equals how much John spent (we'll call it J)"

12+3.50d = J

5. "Stacey bowled x number of games times the cost of one game (call it B) plus the cost of the shoes (call it P) which equals how much they spent (call it S)"

xB+P = S

6. "675.95 dollars was spent at the mall by a number of players (call it P) to equal the total cost per player)"

$675.95÷p (players) = 675.95/p (dollars/player)

Essentially you're making expressions or equations out of numbers you know and putting in variables as place holders for numbers you don't know. The variables can be whatever letters you like, but you'll want to write what each variable represents down nearby. Otherwise the reader/your teacher won't know what's what.

Is this right? Can someone tell me
BARSIC [14]

Answer:

Step-by-step explanation:

m<1 = m<2

8y - 6 = 7y

8y - 7y = 6

y = 6°

m<2 = 7y = 7(6) = 42°
