Answer:
C (20,5)
Step-by-step explanation:
The committees should contain 5 persons each
The number of people are 20
Apply combination concept
where
²⁰₅C = 20! /[ {20-5}!*5! ]
=20! / 15!*5!
=15504 ------The number of 5 person committees that could be formed from a group of 20 people.
Answer:
32 squared units
Step-by-step explanation:
The composite given in the figure consist of 3 triangles and 1 square shape.
To calculate the area of the composite shape, let's calculate area of each shape and then add all together.
==>Area of the square (Q): s²
s = 2
Area = 2² = 4 squared units
==>Area of biggest triangle (B): ½*b*h
b = 2+2+6 = 10
h = 4
Area = ½*10*4 = 5*4 = 20 squared units
==>Area of medium triangle (M): ½*b*h
b = 2
h = 6
Area = ½*2*6 = 6 squared units
==>Area of smallest triangle (S): ½*b*h
b = 2
h = 2
Area = ½*2*2 = 4/2 = 2 squared units
==>Area of composite shape = Q+B+M+S = 4+20+6+2 = 32 squared units
A set of numbers that can be expressed as a fration or ratio
Answer:
I believe the answer is B.
Step-by-step explanation:
The questions says for every 1 hour she reads a book, she reads 0.25 hours with a magazine. Answer B says 2 hours for book, meaning that you wouldn’t have 0.25, you would have 0.5. So for books, you’d go up every 2 hours, and for magazines, you’d continue going up in half’s!
im sorry if this is wrong, but I hope that helped if it’s correct!
(also sorry if the explanation didn’t make any sense)
