Answer:
3 people
Step-by-step explanation:
If there are 16 people in the first lecture and 6 people have brown eyes, the ratio is 6:16. If in the next lecture there is 8 people, all that needs to be done is halving the numbers in the original ratio (to get 16 to 8). Therefore, the ratio is 3:8, meaning 3 people out of 8 would have brown eyes.

Remember
a(b+c)=ab+ac
and you can do ANYTTHING to be
L=5B
divide both sides by 5
L/5=B
sub L/5 for B in other equation
L+7=3((L/5)+7)
distribute
L+7=(3L)/5+21
minus 7 both sides
L=(3L)/5+14
time boths sides by 5
5L=3L+70
minus 3L both sides
2L=70
divide 2
L=35
Answer:
Radius r = ±√52
Coordinates of center =
Step-by-step explanation:
Points to remember
Equation of a circle passing through the point (x1, y1) and radius r is given by
(x - x1)² + (y - y1)² = r ²
<u>To find the radius and coordinates of center</u>
It is given that an equation of circle,
(x - 4)² + (y + 6)² = 52
Compare two equations,
we get r ² = 52
r = ±√52
(x - x1)² = (x - 4)² then x1 = 4
(y - y1)² = (y + 6)² then y1 = -6
Coordinates of center = (4, -6)
Answer:
a) interest in 30 years will be $1,890
b) account balance in 30 years will be $6,390
Step-by-step explanation:
Interest = Principal · Rate · Time
= 4500 (.014)(30)
= 1,890
Total Amount = Interest + Principal
= 1,890 + 4,500
