Answer:
237
Step-by-step explanation:
This is a system of equations.
The theater sold 364 adult and child tickets, so a + c = 364
They made a total of $1930. Each adult ticket was $6 & child tickets were $4. The second equation is 6a + 4c = 1930.
Let's line them up
a + c = 364
6a + 4c = 1930
Since we need to solve for the number of adult tickets, we want to get rid of the c variable. I'm going to multiply the entire first equation by -4 to do this. The second equation stays the same. Now, I have:
-4a - 4c = -1456
6a + 4c = 1930 Add them together
----------------------
2a = 474 Divide by 2 to solve for a
a = 237
There were 237 adult tickets sold
The answer is D) 602.88
Example: The formula is V= pi r*r*h V = 3.14 (4* 4) (12) V = 3.14 (16) (12)
V= 3.14 * 192 = 602.88m squared
Answer:
3695.5 m
1530.73 m
Step-by-step explanation:
Given in the question,
The distance probe travels at an angle of depression 67.4 from the ship to the ocean surface = 4000m
We will use trigonometry identities
<h3>sinФ = opposite / hypotenuse</h3><h3>cosФ = adjacent/ hypotenuse</h3>
1)
distance of probe from top of sea to surface = x
cos(90 - 67.5) = x / 4000
x = 3695.5 m
2)
horizontal distance from ship to probe = y
sin(90-67.5) = y / 4000
y = 1530.73 m

I have done this question before.
Theres not really enough information to work from here. Is there anymore to this problem???
