Answer:

Tony can buy three games with his savings over two months and Alice can buy six concert tickets.  

Step-by-step explanation:

Over two months, Tony has watched a total of 53.6 hours of television (35.4 + 18.2).  If he save $2.50 for each hour, we can multiply his total hours by the amount per hour, or 53.6 x 2.50 = $134.00.  Since each game that Tony wants to buy costs $35.75, we need to divide his total savings by the cost of each game, or 134/35.75 = 3.75.  Since Tony can't buy a portion of the game, the most amount of games he can buy is 3.  Alice watched a total of 48.4 hours of television (21.8 + 26.6).  If she also saves $2.50 per hour, then her total savings is 2.50 x 48.4 = $121.00.  Since her concert tickets are $17.50 a piece, we divide her total savings: 121/17.50 = 6.9.  Alice can also not buy a partial ticket, so the total amount she can buy is 6.

Answer:

53.13

Step-by-step explanation:

To find the measure of an angle use an inverse trig function.

Sin A = \frac{4}{5} so you can take the inverse to find A sin^{-1}\frac{4}{5} = A.

Use a calculator to calculate the value.

A = 53.13
