What is the angle between the hour and minute hand when it is 4:20?

Answers

Answer 1

Answer: $Look\ at\ the\ picture.\n\n\beta=360^o:12=30^o\n\n(20min)/(1h)=(20min)/(60min)=(1)/(3)\n\n\alpha=(1)/(3)\cdot30^o=10^o\leftarrow answer$

Answer 2

Answer: The arc between the 4 and the 5 is (360/12) = 30 degrees.

The hour hand takes a full hour to creep from the 4 to the 5, so it moves
at the rate of ( 30 degrees / 60 minutes ) = 1/2 degree per minute.

In 20 minutes, the hour hand moves (20 x 1/2) = 10 degrees.

At 4:20 , the minute hand is right square on the 4, and the hour hand
is 10 degrees ahead, on its way to the 5 .

The angle between them is 10 degrees.

of a hour. Compute the unit rate by setting up a complex fraction and simplifying.

A)
1 yards per hour

B)
2 yards per hour

C)
5 yards per hour

D)
10 yards per hour

Answers

Answer:

Choice B: 2 yards per hour.

Step-by-step explanation:

In order to compute the unit rate we have to divide the number of yards watered by the amount of hours taken:

$\therefore Unit\: Rate =(yards)/(hours) =((1)/(5) yards)/((1)/(10)hours).$

Take the reciprocal of the denominator of the expression and we get:

$Unit\: Rate=((1)/(5) yards*10)/(hours).$

Which simplifies to

$(2 yards)/(hour)$

Thus Unit rate = $(2 yards)/(hour)$ which is choice B.
