Answer:
Let's begin with a 30°-60°-90° triangle. A 30°-60°-90° triangle with a hypotenuse of 2 um
Step-by-step explanation:
Answer:
11/20
Step-by-step explanation:
5 cents is worth $0.05.
A quarter is worth $0.25.
A dime is worth $0.10
A nickel is worth $0.05
A penny is worth $0.01
In total there are 40 coins in the jar.
The coins that are worth more than $0.05 dollars are the dimes and quarters, so there are 22 coins worth more than $0.05.
Therefore, the probability of of picking a coin worth more than 5 cents is:
22 / 40 = 11/20
Answer:
-5 + 12 i
Step-by-step explanation:
(2 + 3i)^2 = 4 + 6i + 6i + 9i^2
= 4 + 12 i + 9(-1)
= - 5 + 12 i
You are trying to solve for k (get k by itself)
-5k - 19 = 5 - 13k Add 19 on both sides
-5k - 19 + 19 = 5 - 13k + 19
-5k = 24 - 13k Add 13k on both sides
-5k + 13k = 24 - 13k + 13k
8k = 24 Divide 8 on both sides
k = 3
