<h3>
Answer: 400 (choice A)</h3>
==============================================
Explanation:
40% + 35% = 75% of the coins were either made before 1940, or made from 1940 to 1980. In other words, 75% of the coins were minted before 1980. This leaves 100% - 75% = 25% of the coins to being minted after 1980.
25% of 1600 = 0.25*1600 = 400 coins were made after 1980
Answer:
4/16
Step-by-step explanation:
Answer:
It's 90 because we'll make it equal
Answer:
The angle measures are;
36,72, 108 and 144
Step-by-step explanation:
Since it is a quadrilateral
the sum of all the interior angles is 360
so, we have that;
4x + x + 3x + 2x = 360
10x = 360
x = 360/10
x = 36
So each of the angles are as follows;
x = 36
4x = 4(36) = 144
3x = 3(36) = 108
2x = 2(36) = 72
28.8 km should be correct
