x+y≤525 and 9x+5y≤1200 represents the scenario.
Step-by-step explanation:
Given,
Room for people at summer camp = 525 people
Maximum budget = $1200
Cost per adult = $9
Cost per camper = $5
It means that there cannot be spent more than $1200.
x represents the number of adults.
y represents the number of campers.
x+y≤525
9x+5y≤1200
x+y≤525 and 9x+5y≤1200 represents the scenario.

Answer: The distance between them is 230.65 miles.
Step-by-step explanation:
Since we have given that
Speed of plane A (b) = 200 miles per hour
Speed of plane B (c) = 300 miles per hour
Angle between them = 50°
So,
We will use the "Cosine formula", we get

So, distance between the two planes after one hour will be

So, the distance between them is 230.65 miles.
First find how many units of solution there is:
500* 2% = 500(.02) = 10 units
You need 10 units of solution in 'x' units of a 10% solution.
x*10% = 0.1x = 10 units -----> x = 10/0.1 = 100
100 units are needed
Answer:
0.3056 or 30.56%
Step-by-step explanation:
The volume of the grapefruit with the peel is:

When removing the peel, the grapefruit diameter becomes 10 cm (take out 1 cm of peel from each side). The volume of the grapefruit without the peel is:

The percentage of the volume correspondent to the peel is given by the difference between both volumes, divided by the total volume:
30.56% of volume of the grapefruit is the peel.
