0.25 goes into 41 a total of 164 times. to get this answer you take 41 and divide it by 0.25 to get 164.
For part (a), we know that 6/60 pupils wear glasses. We also know that there are 360 degrees in the pie chart. So the angles for people who wear glasses must be (6/60)*360. 6/60 simplifies to 1/10, and a tenth of 360 equals 36. So the angle must be 36 degrees. To find the other angle, simply subtract 36 from 360 degrees to get 324 degrees.
For part (b), it is not possible to tell because all 6 pupils who wear glasses could be girls, they could all be boys, some girls and some boys, etc. We cannot know which one it is, given only that much information.
Hope this helps!
Using a linear function, it is found that the costs are given as follows:
- With r rides: C(r) = 20 + 4r.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Considering the price of admission and the price per ride, the y-intercept is of 20 and the slope is of 4, the cost for r rides is given by:
C(r) = 20 + 4r.
Hence, for 6 rides, the cost is given by:
C(6) = 20 + 4 x 6 = $44.
