A boy can read 5 pages in 15 minutes. A girl can read 15 pages in 1 hour. Explain how you can use a table or graph to find how much longer it will take the girl to read a 300 page book then the boy?

If you use multiplication and division you can figure out that a boy can read it in 15 hours, where as the girl can read it in 20 hours.
Making it into a graph you would then see that the boys line goes up steeper and for not as long and the girls

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
