Answer:
20 different total voting combinations.
Step-by-step explanation:
so lets called them A, B, C, D, and E
If John has to vote on his favorite and second favorite that means we will be selecting 2 bands out of the 5 possible to choose from.
To find the TOTAL amount of different combinations we need to pair up bands and find all the combo's.
Here are the results/totals:
AB
AC
AD
AE
BA
BC
BD
BE
CA
CB
CD
CE
DA
DB
DC
DE
EA
EB
EC
ED
If you want to do it simpler without listing you can take the the 5 bands and multiple by 4 since you know each initial band (A, B, C, D, and E) will be paired with another band other than itself.
You would do 8 / (2/3).
The answer is 12
Answer:
5-8i
Step-by-step explanation:
-7-6i and -12+2i
Treat it as a polynomial. We all know that i=square root of -1, but in this case, treat it as a polynomial.
-12+5=-7
2i-8i=6i
So 5-8i
This creates a right triangle. One leg of the triangle is 25 feet and the other is 10 feet. To find the length of the ladder, we must use Pythagorean theorem.
a = 25
b = 10
c = ?
(25)^2 + (10)^2 = c^2. Square all the terms to the left of the equation and add them together.
725 = c^2. Take the square root of each side.
c = 26.93 feet.
The ladder needs to be 26.93 feet tall.
