because of the communities property
Answer:
Ice rental at the local skating rink is $150 for 2h. Skate rental is $3 per person. The Grade 8 class went skating. All students rented skates. The total cost was $231. How many students went skating?
The first month in which the board will see the cumulative total number of candy bars sold in Manila exceeded the cumulative total in Seoul is of:
3rd month.
<h3>What are linear functions?</h3>
The slope-intercept definition of a linear function is presented as follows:
y = mx + b.
In which the coefficients are defined as follows:
- m is the slope, representing the rate of change.
- b is the y-intercept, representing the initial value.
For the functions in this problem, the slope and the intercept are given as follows:
- Intercept: amount sold by the end of the first month.
Taking the end of the first month as a parameter, the functions are defined as follows:
- Seoul: S(m) = 40 + 60(m - 1).
- Manila: M(m) = 20 + 80(m - 1).
Then Manila exceeds Seoul when:
M(m) > S(m)
20 + 80m - 80 > 40 + 60m - 60
20m > 40
m > 2.
2.1 for example is in the 3rd month, hence the 3rd month is the correct answer.

B
the volume (V) of a sphere = 
πr³
We require to know the radius r to calculate the volume
using surface area of a sphere = 4πr² = 615.752
divide both sides by 4π
r² = 
= 49.0248...
take the square root of both sides
r = 
≈ 7, hence
V= × π × 7³ = 1436.76 m³ → B
