Answer: 8 members of the science group decided to watch the science fiction movie
Step-by-step explanation:
When a group of 40 friends goes to the movies at a multiplex, 1/5 of the group decides to watch a science friction movie. This means that the total sum of the members of the group that decided to watch the science fiction movie and the members that did not watch the science fiction movie is 40.
If 1/5 of the group decides to watch a science friction movie, that means that 1/5 of 40 watched the science fiction movie. It becomes
1/5 × 40/= 40/5 = 8
8 members of the science group decided to watch the science fiction movie.
Answer:
58 in
Step-by-step explanation:
38 divided by 19 = 2
20 divided by 2 = 10
19 x 2 = 38
10 x 2 =20
38 + 20 = 58
if it's a 10% discount that means that it is 90% of the original price. I prefer to solve these types of questions by finding 1%, then multiplying it by 90.
1200 / 100 = 1% of original price = 12$
12$ x 90 = 1080$
I remember that the square of 12 is 144.
Let's work up from there to the squares that 180 lies between.
Keep in mind that squares are when a number multiplies by itself.
For example;
10^2 means 10 • 10, which makes the product of 100.
12^2 = 144
13^2 = 169
14^2 = 196
Well, we have 169 and 196, which 180 lies between.
Your answers are:
13 and 14.
I hope this helps!
115. This is because there are three feet in a yard. If you divide the number of feet by three, you can find the number of yards. Therefore, 345 divided by 3 equals 115.
