Okay. To solve this kind of problem, all you have to do is multiply by 18% (0.18). 300 * 0.18 is 54. There. 54 students have chips.
Answer:
the answer is 200 mph because you take and divide the 400 miles by 20 mph
Step-by-step explanation:
Answer:
How do you represent selling 6 copies as an integer? With -6
How do you represent receiving 24 books as an integer? With 24.
Step-by-step explanation:
The important thing to state here is what is the thing that you are counting.
If you count the number of copies/books that you have, then:
Selling 6 copies means that you have 6 copies less than before, then you would represent this with a -6.
"-6 copies"
And receiving 24 books means that you have 24 books more than before, then you will represent this with a +24.
"24 books"
(You do not need to write the "+" sign, it is implicit if you don't write any sign)
The first one can be done by Pythagoras theorem such as
then
then
The second one can also done by Pythagoras theorem, note that this is isosceles triangle so
, again by using Pythagoras theorem
then
then
For the last one can also done by property of 30-60-90 triangle.
