Answer:

The length of the arc is \frac{5\pi}{3} centimeters.

Step-by-step explanation:

The length of an arc (\Delta s) with a given central angle is determined by the following expression:

\Delta s = \frac{\theta}{360^{\circ}}\cdot 2\pi\cdot r

Where:

r - Radius, measured in centimeters.

\theta - Central angle, measured in sexagesimal degrees.

Given that r = 5\,cm and \theta = 60^{\circ}, then:

\Delta s = \frac{60^{\circ}}{360^{\circ}} \times 2\pi \times 5\,cm

\Delta s = \frac{5\pi}{3}\,cm

The length of the arc is \frac{5\pi}{3} centimeters.

marysya [2.9K]

Answer:

60%

Step-by-step explanation:

12 kids played. 8 didn't play. That means there is a total of 20 students.

The fraction would be 12/20.

To make it into a percent, divide 100 by the denominator (20) and multiply it by the numerator (12)

100 divided by 20 is 5

12 x 5 = 60

Members of a softball team raised $1513.50 to go to a tournament. They rented a bus for $961.50 and budgeted $46 per player for
aniked [119]

Answer: 1513.50=961.50+46x

The number of players the team can bring to the tournament = 12.

Step-by-step explanation:

Let x= the number of players the team can bring to the tournament.

Total money raised = Rent of bus + (Cost per player) (Number of players)

1513.50=961.50+46x\\\\\Rightarrow\ 46x=1513.50-961.50\\\\\Rightarrow\ 46x =  552\\\\\Rightarrow x=\dfrac{552}{46}\\\\\Rightarrow x=12

Hence, the number of players the team can bring to the tournament = 12.
