8 ÷ (2 3/4) = 32/11
248 ÷ (32/11) = B. 85 1/4 cubic feet
9 times 43 is 387 split 9 and 43 and put It in the area model and then add them up
The value of y in the triangle is 2√5
The triangle above is a right angle triangle.
Characteristics of a right angle triangle:
- One of its angle is equals to 90 degrees
- The sides can be found using Pythagoras theorem.
Using Pythagoras theorem
where
c = hypotenuse(longest side)
a and b are the 2 other legs.
Therefore,
6² = 4² + y²
36 = 16 + y²
y² = 36 - 16
y² = 20
y = √20
y = 2√5
