Hi!
The equation to find the area of a triangle is...
(a = area
b = base
h = height)
Fill in the values that we already have.Divide both sides by 1/21722 = 82*h
Divide both sides by 82.1722/82 = 82/82*h
21 = h
The answer is B. 21 cmHope this helps! :)
Answer:
the expressions are not equivalent
Step-by-step explanation:
7(x+2y) (distribute 7 into the parentheses)
= x(7) + 2y(7)
= (7x + 14y) ≠ (14x + 14y)
hence the expressions are not equivalent
Grade level is this. and in my opinion I think it c because the grade level was midpoint at the section?
ANSWER :
A 180 degrees rotation about the origin.
EXPLANATION.
Let us name the vertices of the triangle as follows.
If we reflect the triangle across the y-axis, then we have to negate the x-coordinates
to get,
If we now reflect triangle ∆A'B'C' in the x-axis, we will have to negate the y-values to obtain,
The single transformation that will map ∆ABC to ∆A''B''C'' is
This is a rotation of 180 degrees about the origin.
Answer:
0.0001899
Step-by-step explanation:
Total number to be selected from= 22
The number to be chosen for the event in an ordered sample is 5 from 22 people= 22C5
Where 22 Is the total number of possibilities and 5 is the no of selection
22C5= 22!/(22-5)!5!
= 22!/17!5!
= 22*21*20*19*18*17!/17!*5!
22*21*20*19*18/5*4*3*2*1
=22*7*19*9
=26334
If there is exactly 5 young people in the population, the probability will be 5/22C5
=5/26334
=0.0001899.
