Answer:
4y-5xz has a degree of 2
Step-by-step explanation:
The degree of an expression the the largest degree of any of its terms.
The degree of a term is the sum of the exponents of the variables in that term.
4
y
=
4
y
1
has a degree of 1
5xz=5x1z1
has a degree of ( 1+1)=2
(5xz)
has a higher degree than
(4y)
Therefore the degree of the expression is the degree of
(5xz) , namely 2
Answer:
B
Step-by-step explanation:
B*H= Area of a Triangle
Substitute:
Answer:
52 in Squared (D)
6/45 = 4/x
6x/45 = 4
6x = 180
x = 30
It would take 30 minutes
Permutation: If you are having a race with 10 people, there are 720 different ways that runners can finish the race. Since the order matters, this is a permutation.
10 x 9 x 8 =720
Combination: If you are selecting 3 members to join a club from a class of 10 students, there are 120 different clubs that can be formed. Since the order they are chosen doesn't matter, this is a combination.
(10 x 9 x 8) / 6 = 120
