Answer:
C 13.3 units
Step-by-step explanation:
The Pythagorean theorem is used to find the distance between two points. On a graph like this, you can count the number of squares between points horizontally and vertically, so can fill in the calculation for the hypotenuse directly from the graph.
... hypotenuse length = √((horizontal distance)² +(vertical distance)²)
... JK = √(2²+2²) = √8 ≈ 2.83
... KL = √(2²+5²) = √29 ≈ 5.39
... LM = √(2²+2²) = √8 = 2.83
... MJ = √(2²+1²) = √5 ≈ 2.23
The perimeter is the sum of these distances around the figure:
... perimeter = JK +KL +LM +MJ
... perimeter = 2.83 +5.39 +2.83 +2.23 = 13.3
Answer:
1.52
Step-by-step explanation:
You can convert all the numbers into a fraction to solve the expression.
4/5 is equal to 80/100, and 0.35 is equal to 35/100. (37/100 is left as it is.)
80/100 + 35/100 + 37/100 = 152/100.
When simplified and converted into a decimal, the answer is 1.52.
