An auditorium has rows of seats with 8 seats in each row. Kayla knows there are at least 70 seats but fewer than 340 seats in th

Vera_Pavlovna [14]

Answer:

The possible number of rows can be 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, or 42.

Step-by-step explanation:

First of all, if there are 70 seats, there should be 9 rows. (9*8 =72, which has 70 seats). And, 340 seats are there, so 340/8 = 42.5, i.e. 42 rows can be there at maximum. So, the actual number of rows can be between 9 and 42. Therefore the possible number of rows can be 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, or 42.

Hope this helps. :)

Keisha is working on a math worksheet with 50 problems. She has completed 20 problems in 25 minutes. If she continues at the sam

Sidana [21]

Set up a proportion.

$\sf\dfrac{20}{25}=\dfrac{50}{x}$

Cross multiply:

$\sf1250=20x$

Divide 20 to both sides:

$\sf~x=62.5$

So it will take 62.5 minutes for her to complete the worksheet.

Math graph equation. <br> (Picture.)

vladimir1956 [14]

Answer:

y = -2x + 3 is the required equation

Step-by-step explanation:

From the graph we will get two ordered pairs

If we see that When x=0 then y=3 and when x = 1 then y=1

Now from this we can find the slope of the Graph

So slope of graph = (y2 - y1) / (x2-x1)

=(1-3) / (1-0)

=-2

Slope = m = -2

Now the equation is

y = mx + b

We have to find the value of b

as we have two ordered pairs we can take any of it to find the value of b because line passes through those points

taking (0,3) as a point

y= mx + b

put values

3 = -2*(0) + b

b=3

Now the equation of the line in this form is

y = mx + b

which is

y = -2x + 3
