Answer:
100 m^2.
Step-by-step explanation:
The area of a trapezoid = (h/2) (a + b) where h = the perpendicular distance between the 2 parallel sides and a and b are the lengths of the 2 parallel sides.
Here we have Area = (1/2 * 10) ( 8 + 12)
= 5 * 20
= 100 m^2.
Answer:
At least 6 students must be enrolled in the class for the instructor to make a profit.
At least 20 students must be enrolled in the class for the instructor to make $1,000 (or more) profit per month.
Step-by-step explanation:
The function
models the profit of the instructor of a guitar class per month.
1. If the instructor makes a profit, then

So, at least 6 students must be enrolled in the class for the instructor to make a profit.
2. If the instructor needs to make 1,000.00 profit per month, then

So, at least 20 students must be enrolled in the class for the instructor to make $1,000 (or more) profit per month.
Answer:
26*26*26 = 17576 ways to select 3 letters
10*10= 100 ways to select 2 numbers
So then the total number of ways are:
possible ways
Step-by-step explanation:
For this case we assume that we have 26 letters from A to Z and 10 numbers from 0 to 9 .
And we want to calculate the number of possible passwords possible if the password consists of 3 letters followed by 2 digits.
And for this case we can use the multiplication principle of combinatories, since we don't have any restriction about the letters of the numbers we can have repetition of letters or numbers.
For the number of possible letters:
26*26*26 = 17576 ways to select 3 letters
10*10= 100 ways to select 2 numbers
So then the total number of ways are:
possible ways
