The ropes on either side of a swing are 1.9 m long. If a child swings through a arc length of 0.9 Determine the angle (in radian
Yuliya22 [10]

Answer:

theta = 9/19 radians or  approximately .4737 radians

Step-by-step explanation:

The formula for arc length is

S = r theta  

where theta is in radians.  Lets put in what we know.  The radius would be 1.9 since the ropes would be the radius.

.9 = 1.9 theta

Divide by 1.9 on each side.

.9/1.9 = theta

theta = 9/19 radians

or in decimal form it is approximately  .4737 radians

iris [78.8K]

Answer:

59 patients

Step-by-step explanation:

Total patients Sam saw in a week = 236

Percentage of patients near-sighted = 25%

How many of the patients Sam saw were near-sighted?

Number of patients near-sighted = 25% of 236

= 25/100 × 236

= 0.25 × 236

= 59

Number of patients near-sighted = 59 patients

The number of patients Sam saw in a week that were near-sighted is 59 patients
