A varsity boy's basketball team has ratio of seniors to juniors that is 7:4. If the team is made up of only juniors and seniors,

DENIUS [597]

Answer:

The ratio of seniors to the total team members is 7: 11

Step-by-step explanation:

Let us solve the question

∵ A varsity boy's basketball team has a ratio of seniors to juniors that is 7: 4

∴ seniors: juniors = 7: 4

→ That means seniors have 7 parts and juniors has 4 parts

∴ The seniors' members = 7 parts

∴ The juniors' members = 4 parts

→ Add them to find the total parts of the team

∴ The team's members = 7 + 4 = 11 parts

→ To find the ratio of the seniors' members to the total team's member

divide their parts

∵ The seniors ÷ The total = $\frac{7}{11}$

∵ The seniors' member : The team's members = 7: 11

∴ The ratio of seniors to the total team members is 7: 11

A small cruising ship that can hold up to 66 people provides three-day excursions to groups of 42 or more. If the group contains

lana66690 [7]

<h3>Answer:</h3>

50 people

<h3>Step-by-step explanation:</h3>

Let x represent the number of people on the cruise. The amount they each must pay is ...

... ($58 -(x -42)) = $100 -x

The revenue from the group is the product of the number of people and the amount each pays:

... r(x) = x·(100 -x)

This describes a downward-opeing parabola with zeros at x=0 and x=100. The vertex (maximum) will be found halfway between those zeros, at x=50.

A group size of 50 maximizes revenue from the cruise.
