Nikolay [14]3 years ago

Let x be the width

width = x

Length is twice its width

length = 2x

Perimeter = length + width + length + width

Perimeter = x + 2x + x + 2x = 6x

Given that perimeter = 7 1/3

6x = 7 1/3

x = 7 1/3 ÷ 6 = 1 2/9

So width = 1 2/9

Length = 1 2/9 x 2 = 2 4/9

Area = length x width

Area = 1 2/9 x 2 4/9

Area = 2 80/81 square cm

Quinn is playing video games at a virtual reality game room. The game room charges 20 dollars for every 30 minutes of play time.
CaHeK987 [17]

Answer:

$100  

Step-by-step explanation:    

Let C be the cost for 150 minutes of play time.

We have been given that Quinn is playing video games at a virtual reality game room. The game room charges 20 dollars for every 30 minutes of play time.

We will use proportions to find the cost for 150 minutes of play time as proportions states that two fractions are similar.  

\frac{\text{Cost of 30 minutes of play time}}{\text{30 minutes}}=\frac{\text{Cost of 150 minutes of play time}}{\text{150 minutes}}

Upon substituting the given value we will get,

\frac{20}{30}=\frac{C}{150}

Upon cross multiplying our equation we will get,

30C=150\times 20

Upon dividing both sides of equation by 30 we will get,

\frac{30C}{30}=\frac{150\times 20}{30}

C=\frac{150\times 20}{30}

C=5\times 20

C=100

Therefore, Quinn need $100 to pay for 150 minutes of play time.

The base area is 14 in ² 
The volume is 30.8 in ³ 
For a prism of any cross-sectional area,
Volume = base area * height
=>
30.8 = 14 * height
Solve for height
Height = 30.8/14 = 2.2 inches.

Ans. Joseph has to make the box 2.2 inches high.

19.  Hexagonal prism
Given 
Cross section area = 17.01 m ² 
Height = 16.2 m

Using above formula for volume,
Volume = 17.01 m ² * 16.2 m
=275.562 m ³ 

Answer: The volume of stone is 275. 56 m ³ approximately.
