The answer is 1/2. Count how many a out of the total.
Answer:
C. 120º
Step-by-step explanation:
so we know that the inside of a triangle is 180º and since all the measures are the same we can do 180/3 to find how much each angle is.
180/3 = 60º
now we also know that a straight line is equal to 180º and since we already have one angle, all we have to do is subtract 60 from 180.
180 - 60 = 120º
Answer:
The correct answer is b
Step-by-step explanation:
To find the answer to this question, we would need to find the percentage of each option, and compare it to our question.
95*.8=76<80 Incorrect
120*.75=90>80 correct
270*.2=54<80 incorrect
180*.4=72<80 incorrect
The correct answer is b
Hope this helps!

Answer: 42 = 2*3*7</h3>
Explanation:
Here is list of the first few primes = {2, 3, 5, 7, 11}
Divide 42 over the smallest prime 2 and we get
42/2 = 21
This shows that 2 is a factor (since we get a whole number result).
We don't have another factor of 2 because 21/2 = 10.5 isn't a whole number. But 3 is a factor because 21/3 = 7
Ultimately the numbers 2, 3 and 7 are factors of 42. They are the only prime factors and there's only one copy of each.
42 = 2*3*7
Check out the diagram below. It shows two different ways to generate a factor tree for the number 42.
The answer is D. Tell me if this works.
