Answer:
2 years
Step-by-step explanation:
Simple interest is calculated using the formula: I = prt, where I = the amount of interest earned, p = principal amount, r = rate and t = time. In this case, you know the principal = $2000, the rate = 1.5% or 0.015 and the I = $60, so you are solving for time 't':
I = prt or $60 = $2000(0.015)t
Simplify: 60 = 30t
Divide both sides by 30: 60/30 = 30t/30 or t = 2 years.
I’m not sure what the answer is so better I don’t say I don’t want you to get it wrong
Answer:
15
Step-by-step explanation: I believe that's the answer because the hypotenuse in a 30 60 90 is x2 and 15x2=30
Answer:
81 degrees
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
20 = 2*pi*r
Divide each side by 2pi
20/2pi = 2*pi*r/2pi
10/pi =r
We know the arc length can be found by
s =r theta where theta is in radians
9/2 = 10/pi *theta
Multiply each side by pi/10 to isolate theta
9/2 * pi/10 = pi/10 *10/pi *theta
9*pi/20 = theta
We need to convert to degrees
9*pi/20 * 180/pi
81 degrees
