Step-by-step explanation:
Alrighty, same deal as the last problem, set up a equality, it should look like this:
$1+.80x=$2+.75x
Move the variable to the left of the equation:
.80x-.75x=2-1
Simplify
.05x=1
x=20
Answer:
c. 45.34ft
Step-by-step explanation:
When leg one of the triangle is 15ft and leg two is 17 ft you would take 17^2 + 15^2 and then you find the square root of that (514) to get the hypotenuse of the triangle. After that you multiply by two to account for the 2/2 sqaure foot per each unit
I think that this is a combination problem. From the given, the 8 students are taken 3 at a time. This can be solved through using the formula of combination which is C(n,r) = n!/(n-r)!r!. In this case, n is 8 while r is 3. Hence, upon substitution of the values, we have
C(8,3) = 8!/(8-3)!3!
C(8,3) = 56
There are 56 3-person teams that can be formed from the 8 students.
