Answer:
35 - m
Step-by-step explanation:
A tank containing 35 gallons of water is leaking at a rate of gallon per minute.
"m" represents the number of minutes spent
Number of gallons left in the tank = initial amount of water present – leaked amount of water
Number of gallons of water left = 35 gallons – number of minutes spent rate of leakage.
Number of gallons of water left = 35 gallons – m minutes 1 gallons per minute
Answer:
Step-by-step explanation:
P = 2(l +w)
Let width be x
Length = x + 13
P = 38
38 = 2(x + 13 + x)
38 = 2(2x + 13)
38 = 2x + 26
2x = 38 - 26
2x = 12
x = 12/2
x = 6unit
Width = 6units
Length = x + 13 = 6+13 = 19units
Answer:
380 different ways
Step-by-step explanation:
We can solve this problem using a permutation formula, as the order in a group of two students matter.
So, for this problem, we have 20 students and want to form groups of 2, so we have a permutation of 20 choose 2:
P(20,2) = 20! / (20-2)! = 20! / 18! = 20 * 19 = 380 different ways
Another way to solve this problem is:
For the first student being chose, we have 20 students available, and for the second student, we have just 19, as one was already chose, so the number of ways to choose these two students is 20 * 19 = 380
Step 1: Simplify both sides of the equation.
