There are 4 people in Molly's group.

Step-by-step explanation:

Let,

x be the number of people.

Individual ticket price = $42

Price after discount = $30

Discount per ticket = $3

Discount for x people = 3x

According to given statement;

42-3x=30  

Subtracting 42 from both sides

42-42-3x=30-42\\-3x=-12\\

Dividing both sides by -3

\frac{-3x}{-3}=\frac{-12}{-3}\\x=4

There are 4 people in Molly's group.

The answer to all 11.
madam [21]

Answer:

The rate of the current is 2 miles per hour.

Step-by-step explanation:

Let us assume that the rate of the river is v miles per hour.

The speed of the boat is 12 miles per hour.

Let us assume also that the boat can go 21 miles in t hours in the downstream and 15 miles upstream at the same time i.e. t hours.

So, from the condition given we can write that  

12 + v = \frac{21}{t} ......... (1), and  

12-v =\frac{15}{t} ......... (2)

Now, adding those two equations we get  

24 = \frac{21}{t} +\frac{15}{t} = \frac{36}{t}

⇒ t = \frac{3}{2} hours

Now, from equation (1), we get,  

12 + v = \frac{21}{\frac{3}{2} } =14

⇒ v = 2 miles per hour

Therefore, the rate of the current is 2 miles per hour. (Answer)

A hemisphere fake stone made of clay has a diameter of 16 inches. The density of clay is 0.0035 pounds per cubic inch. The clay
Rufina [12.5K]

Answer:

$137.82

Step-by-step explanation:

The volume of a hemisphere stone is given by the volume of a half-sphere:

Volume = (2/3) * pi * radius^3

If the diameter is 16 inches, the radius is 16/2 = 8 inches, so the volume is:

Volume = (2/3) * pi * 8^3 = 1072.33 in3

We need a total of 8 stones, so the total volume is:

Total Volume = 8 * 1072.33 = 8578.64 in3

The density of clay is 0.0035 pounds per cubic inch, so the total weight of the 8 stones is:

Weight = Total Volume * density = 8578.63 * 0.0035 = 30.0252 pounds

Finally, if the price of each pound of clay if $4,59, the final price is:

Price = 30.0252 * 4.59 = $137.82

An architect is designing a sandwich shop, as shown in the
STALIN [3.7K]

The length of both rooms is 10 meters and the width for the kitchen is 5 meters, while the one for the dining room is 9 meters.

<h3>How to find the length of the rooms?</h3>

Both rooms have the same length but different areas and different widths. This common measurement can be found using the GFC or the greatest common factor. To do this, divide each number by 1,2,3, etc., and find the greatest common number (only integers are valid).

  • 50: 50 25 10 5 1
  • 90: 90 45 30 18 15 10 9 6 5 3 2 1

The greatest common number is 10, so 10 meters is the length of the room.

<h3>How to find the width?</h3>

Use the formula

  • A = lenght x width or width = area / lenght

Kitchen.

  • Width: 50 / 10
  • Width: 5 meters

Dining room:

  • Width: 90 / 10
  • Width: 9 meters

Note: In this question the diagram is missing; below, I attach the diagram.
