Answer:
about 7.61%
Step-by-step explanation:
Put the given numbers into the formula and solve for r.
2200 = 1900(1 +r)^2
√(22/19) = 1 +r
r = √(22/19) -1 ≈ 0.076055 ≈ 7.61%
Answer:r=0.001 I think
Step-by-step explanation:
Answer:
The answer is either 9/200 (nine two-hundreths) or 22
Answer:
A= 30
Step-by-step explanation:
This requires several steps.
First, you need to find the 2 other missing angles.
One can be found easily by substracting 130 from 180
so 180-130 = 50
The other angle is the same as 8x+4
Now set up your equation
180=3x-6 + 8x+4 +50
180 = 3x + 8x -6 + 4 +50
180+6-4-50 = 11x
132 = 11x
132/11 = x
12 = x
Now plug in 12 for x in your angle A
A=3x-6
A=3 * 12 - 6
A=36 - 6
A= 30
