Step-by-step explanation:
All angles of a triangle must add up to 180,
So we just take angle ACB and angle EFG, add them and then subtract the sum from 180
(angle ACB + angle EFG) - 180 = angle GEF
Answer:
The value of rate of decrease of volume = - 3600
Step-by-step explanation:
According to Boyle's law P V = C ------- (1)
Pressure ( P ) = 100 k pa = 10
Volume ( V ) = 900
Put these values in equation ( 1 ) we get,
⇒ C = 10 × 900 = 9000 N-cm = 90 N-m
Differentiate Equation ( 1 ) with respect to time we get,
⇒ V + P = 0
⇒ V = - P
⇒ = - ---------- (2)
This equation gives the rate of decrease of volume.
Given that Rate of increase of pressure = = 40
C = 90 N-m
P = pa = 10
V = 900
Put all the above values in equation 2 we get,
⇒ = - × 40
⇒ = - 3600
This is the value of rate of decrease of volume.
Answer:
$2
Step-by-step explanation:
Let, price of individual child ticket is $x, and price of individual adult ticket is $y.
Now, on Friday we can write an equation is 55x+20y=200....(1).
and on Saturday we can write an equation is 72x+36y=306.....(2).
so, Equation 1: 55x+20y=200
Equation 2: 72x+36y=306
now, we are going to solve both equations.
after solving you will find x=2 and y=4.5
Hence, we can say that the cost of child ticket is $2, and the cost of adult ticket is $4.50.
