18:30 can be expressed as 18/30
18/30 simplifies into 6/10
6/10 simplifies into 3/5
120 is your answer cause half 120 is 60
Answer:
80 units²
Step-by-step explanation:
Given <u>vertices</u> of a rectangle:
- A = (-8, 5)
- B = (2, 5)
- C = (2, -3)
- D = (-8, -3)
As points A and D share the <u>same x-coordinate</u>, and points B and C share the <u>same x-coordinate</u>, the difference between the different <u>x-coordinates</u> is the length of the rectangle:
As points A and B share the <u>same y-coordinate</u>, and points C and D share the <u>same y-coordinate</u>, the difference between the different <u>y-coordinates</u> is the width of the rectangle:
Therefore:
15.8 km each day for 18 days...
so he biked a total of (15.8 * 18) = 284.4 km <==
