Answer:
B. 1.2 x 10^-1
Step-by-step explanation:
3.6 x 10^7 = 36,000,000
3 x 10^8 = 300,000,000
36,000,000 ÷ 300,000,000 = 0.12
= 1.2 x 10^-1
Answer: 51
Step-by-step explanation:
let x be the number.
(70%)x = 42
0.7 x = 42
x = 60
we check 15% x 60 = 0.15 x 60 = 9, which is true.
85% of that number = 85% x 60 = 0.85 x 60 = 51.
The probability of getting a certain bill without replacing are as follows:
The probability of getting a five dollar bill is 5 over 14.
The probability of getting a ten dollar bill is 6 over 13.
The probability of getting a twenty dollar bill is 3 over 12.
30*4 = 120 (120 oranges=total oranges needed)
120/20=6
