Answer:
16 divided by 14.24 = 1.12359550562
If you round it would be: $1.12
He was wrong, you cannot make 10 coins by adding 32 coins to 28 coins. If you want to obtain 10 coins from 32 coins and 28 coins, you can subtract 28 coins from 32 coins.
This can be illustrated as follows:
32-28=10
Answer:
5
Step-by-step explanation:
5 of them play neither sport.
We can subtract 5 from 21 to get the kids that play a sport.
16-(14+6), is -4.
so 4 is the number of kids that play both sports.
so the probability is 4/21.
Sin angle that equals the 1/2 value is the 30 degree on the 1st Quadrant.
The angle of 30 degree on the 3rd Quadrant is equivalent to (formula and circle in the 1st photo) 180 + 30 = 210°.
So theta = 210° (3rd Quadrant) = 30° (1st Quadrant).
Now just transfer the cos 30° to the 3rd Quadrant and the signal will be negative (as shown in the 2nd photo attached).
5.30 because 3 is smaller than 30
