The minutes and seconds hands of a clock rotates in a circular manner no matter the shape of the clock. Therefore the distance covered by the minute hand of the clock is calculated by the circumference of a circle:

C = 2πr

C = 2 * $\frac{22}{7}$ * 22

C = 138.23 feet

OLga [1]

Answer:

Final cost of ticket = $205

Step-by-step explanation:

Speed limit is given: 60 miles per hour

Car travelling at a speed of: 78 miles per hour

Car is exceeding speed limit by: 78 - 60 = 18 miles per hour

We are given that the dine ticket includes $25 plus $10 for each mile over the speed limit:

Final cost of ticket = $25 + (miles over speed limit * 10)

= 25 + (18*10)

= 25 + 180 = $205

2. Hessa was playing a computer game. She scored 43 points in Round 1 and 26 points in Round 2. Which sum could she use to add t

murzikaleks [220]

Answer:

Step-by-step explanation:

Points scored by Hessa is as shown below;

Round 1 = 43 points

Round 2 = 26 points

Total points for both rounds = 43 + 26 = 69 points

To determine the sum she could use to add the points together, we must select the sum that will give us the same total of points for both rounds i.e 69 points.

The Round 1 score (43 pt)can also be expressed as (40+3) points

The Round 2 score (26 pt)can also be expressed as (20+6) points

The sum she could use to add the points together will be (40+3)+(20+6)

which is also equal to 40 + 20 + 3 + 6 = 69points

Hence, option a is correct
