Answer:
21 matches
Step-by-step explanation:
This is a combination problem where we have to select two member out of 7 members
So we want calculation of 7C2
7C2 = 7!/[(2!)(7-2)!]
(7*6*5*4*3*2*1)/[(2*1) *(5*4*3*2*1]
(7*6)/2 ~ Note everything that easily cancels here!
42/2
21 matches
Step-by-step explanation:
First, find 12 percent of 1,150,
12 percent of 1,150 = 138.
Now, add 1,150 + 138,
1,150 + 138 = 1,288
Hope I helped, if not, at least I tried.
Answer:
216
Step-by-step explanation:
I'm sure there is a simpler way to do this but this is how I did it.
First divide 18 by 6 because it triples every 6 hours.
18/6=3
This means it will triple three times
Then triple the value three times
#1. 8x3=24
#2. 24x3=72
#3. 72x3=216
In 18 hours the virus will infect 216 people.
For this case we have:
By properties of the radicals 
So:
.
Now, for power properties we have:
Thus, 
So:
in its radical form
Answer:
in its simplest form.
in its radical form
Answer:
a 36
Step-by-step explanation:
There are 360 degrees in a circle.
If it has rotation order 10, divide 360/10
