R * s = 273
r = s - 8.....s = r + 8

r(r + 8) = 273
r^2 + 8r = 273
r^2 + 8r - 273 = 0
(r - 13)(r + 21) = 0

r - 13 = 0
r = 13

r + 21 = 0
r = -21.....extraneous solution...not ur answer

r = 13
s = r + 8 = 13 + 8 = 21

so there are 13 rows.....each row containing 21 seats

Answer:

8.6 to the nearest tenth.

Step-by-step explanation:

Using the distance formula d =  √ [(y2 - y1)^2 + (x2 - x1)^2] where (x1, y1) and (x2, y2) are the two endpoints.

= √ (4 - -3)^2 + (-3-2)^2

A train traveled 210 mi in 3.5 h to its first stop. It then continued on traveling another 130 mi in 2.5 h.
11111nata11111 [884]

Answer:

56.7 ​ mi/h​


Step-by-step explanation:

The formula for average speed is:

Average Speed = \frac{TotalDistance}{TotalTime}


Thus we have:

Average Speed = \frac{210+130}{3.5+2.5}\\=\frac{340}{6}\\=56.66 mph


<em>Rounding to the nearest tenth, we have </em>

Average Speed = 56.7 mi/h
