223.83 + 318.85 + 63.83 = 606.51
100 - 10 = 90 --> 1 - 0,10 = 0,90
606.51 * 0,90 = 545.859
545.859 * 1,06 = 578.61054 ≈ $ 578.61
I would round 739 to 740 and then divide it by 18 getting the answer of 41.11111111 or just 41 or 40
Answer:
7.5 cm.
Step-by-step explanation:
Let x represent the distance on map.
We have been given that a scale on a map shows that 3 centimeters represents 10 kilometers. We are asked to find the distance on map that corresponds to 25 kilometers in actual.
We will use proportions to solve our given problem.
Upon substituting our given values in above proportion, we will get:
Therefore, 7.5 centimeters on the map represents an actual distance of 25 kilometers.
When you have parallel lines cut by a transversal, alternate interior angles are congruent.
The 80 degree angle and the (20 + x) angles will be congruent.
Therefore, x = 60 degrees.
