The Celluloid Cinema sold 150 tickets to a movie. Some of these were child tickets and the rest were adult tickets. A child ticket cost $7.75 and an adult ticket cost $10.25. If the cinema sold $1470 worth of tickets, which system of equations could be used to determine how many adult tickets, a, and how many child tickets, c, were sold? A)a+c=150a+c=150
10.25a+7.75c=147010.25a+7.75c=1470< br />
B)a+c=150a+c=150
7.75a+10.25c=14707.75a+10.25c=1470< br />
C)a+c=1470a+c=1470
10.25a+7.75c=15010.25a+7.75c=150

D)a+c=1470a+c=1470
7.75a+10.25c=1507.75a+10.25c=150

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
