icang [17]

Answer:

2/5 of a mile

Step-by-step explanation:

The easiest approach is to realise that one hour is 3 times longer than

20 minutes. The longer the time, the more they will pave.

2/5 of a mile, in 20 minutes, how much in 60 minutes?(#)

They will pave 3 times more.

2/15 x 3/1 = 6/15 of a mile

6/15 = 2/5 of a mile

You spin the spinner and flip a coin. Find the probability of the compound event.

Mademuasel [1]

Answer:

The probability of spinning an even number and flipping heads is 1/4

Step-by-step explanation:

You spin the spinner and flip a coin.

A spinner that has 1 of each number, 1-6

Total events =12

(1,H),(2,H),(3,H),(4,H),(5,H),(6,H)

(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)

We are supposed to find probability of spinning an even number and flipping heads

Favorable events : (2,H),(4,H)(6,H) = 3

Total events = 12

The probability of spinning an even number and flipping heads = $\frac{3}{12}=\frac{1}{4}$

Hence The probability of spinning an even number and flipping heads is 1/4
