Answer:
Could be wrong but my answer would be none because the angles in a triangle have to add to 180 degrees
Step-by-step explanation:
Not impressed that you consider yourself "too lazy" to at least get started on the solution of this problem. Why not "give it the old college try?"
Start by choosing letters to represent the unit cost of each popcorn and drink:
p: popcorn, d: drink.
Then 2p + 3d = $22.25 and 12p+4d=$39.00
Note that the unit of measurement of all 6 terms here is " $ ".
Solve this system of linear equations simultaneously:
2p + 3d = $22.25
12p+4d=$39.00
In your shoes I would mult. the first equation by -6 and then combine the result with the second equation. p will temporarily disappear, and you'll be left with an equation in d only, enabling you to find the unit cost of a drink.

Answer:
5 seconds
Step-by-step explanation:
In order to find the time when it landed, we will have to find the x-intercepts.
Equation given to us : -16t² + 48t + 160
Let's take the GCD, which is -16.
-16( t² - 3t - 10 )
Factoring what's inside the brackets, we get the x-intercepts.
What multiples to -10 but adds up to -3? The numbers are -5 and 2
-16 ( t - 5 ) ( t - 2 )
X-intercepts are t - 5 and t - 2
Which is 5 and 2 seconds. But one of this is an extraneous solution and that is 2.
If we substitute the value of 2 in the equation, we will not get 0.
During the x-intercept, the x has a value and y is 0. If we substitute 5 ans x. we will get y as 0.
Hence, the answer is 5 seconds.
