A theater has 20 seats in the first row, 22 in the second row, 24 in the third row, and so on for 25 rows. How many seats are in the last row?

Answers

If the number of seats that are in the last row is 1100 seats.

Number of seats

First row=20

Second row=22

Third row=24

A.P = 20,22,24,…

a=20

d=22−20=2

n=25

Using the formula of the sum of the first n terms of an A.P

Sn=n/2[2a+(n−1)d]

S25= 25/2 [2×20 +(25-1) 2]

S25 = 12.5 [40 +24 ×2]

S25= 12.5 [88]

S25= 1100

Therefore If a theater has 20 seats in the first row, 22 in the second row, 24 in the third row, and so on for 25 rows. The number of seats that are in the last row is 1100 seats.

I need help ASAP (10 points) I checked and the only information I got was that x=8 I don’t know how to get the answer 8

Answers

Answer:

x=8

Step-by-step explanation:

This is a congruent triangle. If we use Pythagorean theorm, we can see that 3^2+y^2=25

y^2= 16

y=4

(y is the base of the small triangle)

and since the big triangle and the small triangle are congruent(the ratios are the same), 3 is half of 6, and so the base of the small triangle is half of the big triangle's.

What is the change in temperature from 20 degrees F dropping to -33 degrees F?

Answers

Answer:

53 degrees.

Step-by-step explanation:

Your just finding the difference or the "change" So I did 20+33=53.

Because if it is 20 degrees and has to get to -33 then to get to 0 degrees it's minus 20 then to get to -33 its minus 33 so total I have changed the temp by 53 degrees. Sorry, this was so confusing it's very hard to word.

Answer:

250 feet

Step-by-step explanation:

Answer:

1)"rise over run" = 1.5/18 = 3/36 = 1/12 for the 1st section to the landing

2)slope is the change in height, the vertical change, divided by the change in horizontal distance

3)2nd section has slope 1/18 and covers 9 feet. That means it rises 1/2 foot

4)slope = 1/18 = (1/2)/9

5)the door is 2 feet higher than the ground level, 1.5 + .5 = 2 feet change vertically
