Answer:
5/27
Step-by-step explanation:
I wrote it as a fraction, but the explanation is, if you're finding out how many who don't play instruments, you first need to find out who many do play instruments, so you add the numbers together.
10+5+7 = 22
So the probability that you'll pick one who does play an instrument would be 22/27 (because 22 out of the 27 pupils play an instrument.) But remember that's not what it's asking us for.
You have to subtract 27 - 22 to get the pupils who don't play instruments, you get 5, so the probability is 5/27 (5 pupils out of 27 don't play instruments.)
To put this in a percent, just divide the top number by the bottom number and move the decimal 2 places over, you get 18.5% or 19% both answers are correct depending on rounding.
Answer:
30, 60, and 90
Step-by-step explanation:
because it is reflected it would be the same because it is congruent
Answer:
C
Step-by-step explanation:
THe markup is the difference between the Selling Price and Cost.
As a percentage, we would get the markup in terms of cost.
First,
Selling Price = 4.50
Cost = 3.00
So,
Markup = SP - Cost = 4.50 - 3.00 = 1.50
As a percentage, we would divide the markup by cost and then multiply the answer by 100. That's:
1.50/3 = 0.5 * 100 = 50%
THe markup is 50%
C is the correct answer.
I’m not sure what 1. is sorry, but I think I know what 2 and 3 are.
2.) 120/1 x 3/4 because 3/4 is just the fraction form of 75%. Also 120/1 is just 120 as a fraction
3.) 1,200 x 0.03 because 0.03 is just the decimal form of 3%
