The value one unit of the bar model is 12
Step-by-step explanation:
The bar is divided into 8 units in the diagram (not available in this question)
We need to find the value of each unit
If x is value of 1 bar,
8x = 96
x = 96/8
So, x = 12
Hence the value one unit of the bar model is 12
Answer:
PR = 39 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
PR² + PQ² = QR² , that is
PR² + 80² = 89²
PR² + 6400 = 7921 ( subtract 6400 from both sides )
PR² = 1521 ( take the square root of both sides )
PR =
= 39
