lbvjy [14]4 years ago
8 0

Answer:48

Step-by-step explanation:

Total number of students=397

Students that travelled in a car=29

Let the students that travelled in a bus be represented by y.

Since 8 buses were filled, it will be 8y for total students

8y + 29= 397

8y= 397-29

8y= 368

Divide both side by 8

8y/8=368/8

y = 46

Number of students in each bus is 46

kompoz [17]

Answer:

The tip of the minute hand move in 24 hours is 150.85 inches.

Step-by-step explanation:

Given : The minute hand of a clock is six (6) inches long.

To find : How far does the tip of the minute hand move in 24 hours?

Solution :

We know that,

1 hour = 60 minute

24 hour = 24\times 60=1440

The angle form is \theta=1440.

The radius is r=6 inches

Using length of arc formula,

l=2\pi r\times \frac{\theta}{360}

l=2\times \frac{22}{7}\times 6\times \frac{1440}{360}

l=2\times \frac{22}{7}\times 6\times 4

l=150.85

Therefore, the tip of the minute hand move in 24 hours is 150.85 inches.

A total of 202 tickets were sold for a theatre showing. If child tickets cost $6 and adult tickets cost $10, how many tickets of
polet [3.4K]

Answer:

167 adult tickets were sold

35 children tickets were sold

Step-by-step explanation:

Let the number of adult tickets be x

Let the number of children tickets be y

Total number of each ticket sold;

x + y = 202 equation 1

Total cost of the tickets

10x + 6y = 1708 equation 2

Let

x= 202 - y equation 3

Substitute 3 into 2

10(202 - y) + y = 1708

2020 - 10y + y = 1708

-9y = 1708 - 2020

-9y = -312

y= 35

Substitute y =35 into 1

x + 35 =202

x= 202 - 35

x= 167

Therefore;

167 adult tickets were sold

35 children tickets were sold

If 2b=30p, why is p=15b?
patriot [66]

Answer:

  It's not. b = 15p

Step-by-step explanation:

The <em>division property of equality</em> says you can divide both sides of an equation by the same number without changing the values of the variables. When we divide both sides of the given equation by 2, we get ...

  2b/2 = 30p/2

  b = 15p . . . . . . . simplify
