Answer:
James and Alisa practiced for 288 minutes.
Step-by-step explanation:
James practiced piano for 48 minutes. Alisa practiced for 5 times as long as James.
Let Alisa practiced for x minutes.
So, equation becomes:
minutes
Hence, Alisa practiced for 240 minutes.
Let the time played together be represented as y. So, we can denote y as:
y = 288 minutes
Therefore, James and Alisa practiced for 288 minutes.

Answer:
Both triangles are scalene & Both triangles have an obtuse angle.
Step-by-step explanation:
<u>Key skills needed: Triangle recognition, Comparing Triangles</u>
1) We are given those 2 triangles, and we need to see if they are isosceles, scalene, obtuse, and acute.
2) To get this, let's define each thing:
Acute triangle - Means that all the angles in triangle are acute, which means they are less than 90 degrees in measure.
Obtuse triangle - Means that one angle in the triangle is obtuse, which means it is greater than 90 degrees in measure.
Scalene triangle - All the sides of the triangle are different in size/length
Isosceles triangle - 2 sides of the triangle are the same length
3) Now, we can use this to see what both triangles are:
--> Both triangles are not isosceles, they are both scalene. This is because all the sides of each triangle are different in size/length. This makes it scalene.
--> Both triangles are not acute triangles, they are both obtuse triangles. This is since the largest angle in each triangle is clear an obtuse angle (it looks like it is more than 90 degrees). Refer to the image I post as help.
With the observations above: We can say that both triangles are scalene, and both triangles are obtuse triangles.
