The formula for the circumference is:
So to find first radius:
Second radius:
The ratio between them is:
Answer:
x = 3
Explanation:
To simplify this equation, don't worry about the -3, since there is one on both sides. Therefore, they cancel out.
So, 9 + x = 4x
When you plug 3 in for x, it becomes:
9 + 3 = 4 x 3
12 = 12
This equation is true, therefore, x is your answer!
Well looking at the information in triangle ABC you know
Angle B + Angle C = 180 - 144
so Angle B + Angle C = 36
since the triangles are similar let angle M = x
then Angle C = 2x and angle B = angle M but the similarity postulate
so form an equation
2x + x = 36
solve for x
Hope it helps
Answer:
Step-by-step explanation:
let x be the population
so we have ,
2x= 6h
?= 3 days or 3×24h
by cross multiplication we have
2x× 72h= 6h×?
?= 2x×72/6 = 24x
So, in three days the bacteria will b 24 times current population.
Answer:
Part C
Look at the circle you created that has point C(the midpoint of AB) as its center and passes through point A.
What can you say about AB, about the inscribed angle of a circle, and include your reasoning in your response.
