156+4x=180
4x=180-156
4x=24
X=24/4

A stadium has 55000 seats in total. Seats in section A sell for $30, $24 in section B, and $18 in section C. The total number of

kolezko [41]

Answer:

A= 27500 seats, B= 14200 seats, C= 13300 seats

Step-by-step explanation:

a=b+c

a+b+c=55000 seats

30a+24b+18c=1405200 dollars

substitue a for b+c

b+c+b+c=55000

30(b+c)+24b+18c=1405200

seats 2b+2c=55000 --> divide by 2 on both sides b+c=27500 --> c=27500-b

dollars 30b+30c+24b+18c=1405200 --> 54b+48c=1405200 divide by 6 --> 9b+8c=234200

substitute c for 13750-b

9b+8(27500-b)=234200

9b+220000-8b=234,200

b=14,200 seats

c=27500-b=27500-14200=13300 seats

a=55000-b-c=55000-27500=27500 seats

Use volume displacement to determine the volume of this metal sample to the nearest 0.1 ml.

umka21 [38]

The volume displacement method is a manifestation of Archimedes' Principle. This principle states that the volume of the object placed on a known volume of water, is equal to the volume of water displaced. Actually, it could just be any liquid. Thus, whatever the displaced volume is, that is equivalent to the volume of the metal sample. I can't give an exact answer because there is no given information. But the concept works that way.

This diagram shows a pre-image △ABC , and its image, △A′′B′′C′′ , after a series of transformations.

Stella [2.4K]

First ABC is reflected across the y axis to become A'B'C'

Then A'B'C' is rotated 90 counterclockwise about the origin to make it A"B"C"

Because the transformations are both rigid, the pre-image and image are congruent

Hope this helped

What is the ones digit of a number if its cube ends in 7

Ostrovityanka [42]

Well, I have never seen a question posed this way, but let's check it out by trial and error.

1^3 = 3

2^3 = 8

3^3 = 27 Hey! There's one. And the ones digit ends in 3.

Let's try another number that ends in 3 and see if it works as well.

13^3 = 2197 Wow. It works again. I never noticed this before, so you taught me something new.

I will test one more.

33^3 = 35937 Bingo. I think we have a winner.
