The answer to your problem A=60
Answer:
a = 60 degrees and b = 30 degrees
Step-by-step explanation:
30 degrees (line E) = angle b
angle b = 30 degrees
there is a right angle plus the 30 degrees = 120 degrees.
180 - 120 = 60 degrees which is angle a
A. x= 11/5
b. x= 6
c. x= -12/2
d. x= 6/5
Answer:
1/3 or 33%
Step-by-step explanation:
Since there are 3 sweaters and only one is green, the ratio of green sweaters to all sweaters is 1:3. As a fraction, this ratio is 1/3. Finally, as a percentage, this fraction/ratio is 33%. Therefore, there is a 33% chance Stephen pulls out a green sweater.
The formula is principal x ( 1+ interest rate)^ number of years
5%:
20,000 x 1.05^3 = $23152.50 total
Interest = 23152.50-20000= $3,152.50
10%
20000 x 1.10^3 = $26,620.00
Interest = 26620-20000 = $6,620
12%
20000 x 1.12^3 = $28,098.56
Interest = 28098.56-20000 = $8.098.56
