Answer:
8- agree with jordan10- 36 seconds in
Step-by-step explanation:
8-
21÷28=75 percent
30÷40=75 percent
Jordan is right, they both equal the same amount (.75) when divided
10- the red and blue light blink the same time on the 36th second this is because both 9 and 12 are dividable by 36
9,18,27,36
12,24,36
x = 109°
3*180° - 100° - 102° - 108° - 121° = 109°
Find the GCD (or HCF) of numerator and denominator
GCD of 52 and 24 is 4
Divide both the numerator and denominator by the GCD
52 ÷ 4
24 ÷ 4
Reduced fraction: 13/6
Multiply all of the numbers together: 5 x 2 x 8 = 10 x 8 = 80 ways
