Section J has 20 rows....each row has 15 seats....so section J has (20 * 15) = 300 seats. If each seat costs $ 18, and all the seats are sold, then the amount of money collected would be : (300 * 18) = $ 5,400 <=

A pizza dlivery car can travel 11 km for every gallon of gasoline it uses. If the driver's average speed is 28 km/h, how many ho
Svetlanka [38]

Answer:

13.75 hours

Step-by-step explanation:

First, find how many km the driver can travel:

11(35)

= 385

Then, divide this by 28 to find how many hours the driver can travel:

385/28

= 13.75

So, the driver can travel 13.75 hours

A bag contains 4 red marbles, 6 blue marbles, and 8 green marbles. One marble is to be chosen at random.
goldenfox [79]
4 red marbles
6 blue marbles
8 green marbles

Add:

4 + 6 = 10
10 + 8 = 18
18 total marbles 

Green marbles/total marbles 
 
8/18

Simplify:

8 ÷ 2 = 4
18 ÷ 2 = 9
Simplest form = 4/9 

8/18 = 4/9

Make a table of ordered pairs for the equation. y= 1/2x − 3
Dennis_Churaev [7]

Answer:


Step-by-step explanation:

Please enclose the fractional coefficient inside parentheses:  y= (1/2x) − 3 for greater clarity.

Make a table of ordered pairs:

x    y = (1/2)x - 3

0                   -3

1            (1/2)(1) - 3 = -2 1/2

3           (1/2)(3) - 3 = -3/2

The y-intercept is the point at which x = 0, and (from the table) is -3.  Plot a dark dot at (0, -3).

Now graph (3, -3/2), leaving a dark dot.

Draw a line thrugh (0, -3) and (3, -3/2).

Consider the line y=7x-3 fine the equation that pass through -5,6 of a perpendicular​
Pavel [41]

Answer:

y=-\frac{1}{7}x+\frac{37}{7}

Step-by-step explanation:

Your equation is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.  Your line has a slope of 7.  In order to find the line perpendicular to this line, we have to take the opposite reciprocal of the slope.  The perpendicular slope to m = 7 is m = -1/7.  Now we go through x = -5 and y = 6 to find the new equation.

6 = -1/7(-5) + b gives us

6 = 5/7 + b and

b = 37/7

Therefore, the equation of the line perpendicular to your original line is

y = -\frac{1}{7}x + \frac{37}{7}
