Answer:
Step-by-step explanation:
First, you need to find the fraction of the passengers who are not senior citizens. Add 1/5 and 2/3 to get 13/15.
This means that 13/15 of the passengers aren't senior citizens and 2/15 of the passengers are senior citizens.
Hope i helped!
Answer:
60°
I hope I'm correct thanks
B because 13 x 13 = 169
3.14 x 169 = 530.7
Answer:
(x+1)²+(y-2)²= 20
Step-by-step explanation:
P = (-3,-2)
Q = (1, 6)
<u>Center (h, k)</u>
C = ((-3+1)/2 , (-2+6)/2)
C = (-2/2 , 4/2)
C = (-1 , 2)
Radius = Distance from the center to point Q
R = √((1-(-1))² + (6-(2))²)
R = √((2)² + (4)²)
R = √(4+ 16)
R = √20
Equation
(x-h)²+(y-k)²= R²
(x-(-1))²+(y-2)²= (√20)²
(x+1)²+(y-2)²= 20
The number of parents is c -9 since there are 9 more children than parents
And we know that the total number of people in the room is 25 so:
c + c-9 = 25
or
2c - 9 = 25
We can then solve for c
2c = 34
c = 17
