8 inches per sec
40 feet = 480 inches
480÷60 =8
(a) 1A 2A 3A 1B 2B 3B (6 possible outcomes
(b) Possible outcomes for A or 1 are 1A 2A 3A and 1B ( 4 outcomes) therefore:
Probabilty = 4/6 = 2/3
21 - (3 x 4)
3 x 4 is 12, so it becomes 21 - 12.
21 - 12 = 9
Answer:
178.1
Step-by-step explanation:
In the first blank, write in 7 for x, and in the second blank, write in 8 for y. Then perform the indicated multiplication and addition.
