The area of circle-A is four times the area of circle-B .
Answer: ∠B=70°
Step-by-step explanation:
It is shown in the diagram that ∠A and ∠B is vertical angles.
- Vertical angle theorem: opposite angles are congruent.
<u>Solve:</u>
∠A=∠B
8x+6=4x+38
4x=32
x=8
<h2>∠B=4x+38=4(8)+38=32+38=70°</h2>
Answer:
1.66 on the top and 5 on the bottom
Step-by-step explanation:
3 ÷5= 1.66
2÷10=5
2.80 is more than 2, i would round it.
So sorry if this is wrong :(
Answer: 59106
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^ t
Where
A represents the population after t years.
t represents the number of years.
P represents the initial population.
r represents rate of growth.
From the information given,
P = 60000
r = 0.1% = 0.1/100 = 0.001
t = 2015 - 2000 = 15 years
Therefore
A = 60000(1 - 0.001)^15
A = 60000(0.999)^15
A = 59106
