Answer:
40
Step-by-step explanation:
Let the number of 20cent coins be 'x'
Then, 10cent coins are 'x + 12'
Total amount = $5.4 = 540 cents
20(x) + 10(x + 12) = 540
20x + 10x + 120 = 540
30x = 540 - 120
30x = 420
x = 420/30
x = 14 (14 20cent coins)
x + 12 = 26 (26 10cent coins)
Total coins = 14 + 26 = 40
6.4 x 10^3 = 6400
1.4 x 10^4 = 14000
7.5 x 10^3 = 7500
total = 6400 + 14,000 + 7500
total = 27900 or 2.79 x 10^4 <===

Step-by-step explanation:
The possible measures of the angle at the center of the circle formed by the minor arc are 17°, 75°, and 149°.
<h3>What is the minor and major arc?</h3>
A major arc is an arc in the circle which measures less than 180° at the center of the circle, while a major arc is an arc that measures more than 180° at the center of the circle.
We know about the major and minor arc, therefore, from all the given options, 17°, 75°, and 149° are the measure of the angle that is less than 180°. Thus, these angles are will form the minor arc.
Hence, the possible measures of the angle at the center of the circle formed by the minor arc are 17°, 75°, and 149°.
