How would you solve for x and y?

Mathematics

Sholpan [36]3 years ago

Since all of the sides are 15, and there's a right angle, we can assume the triangles are both the same size. So we can halve 15 to get the length of y, which would be 7.5. And here we can use the Pythagorean's Theorem to solve for x, by changing it to c^2-b^2=a^2, and we can fill out 15^2 - 7.5^2 = a^2, or 225 - 56.25 = √173.75, which is about 13.18.

2. Lawn tickets cost $30 each and seat tickets cost $50
Andreas93 [3]
Okay so.
If lawn tickets are $30 and seat tickets are $50 and they sold 200 seat tickets.
50 multiplied by 200 is = $ 10,000
And the goal is $14,000.
So $14,000 subtract $10,000 is $4000
$4000 is how much they made in Lawn Tickets. In order to calculate how much lawn tickets were sold, is dividing $4000 by $30 since lawn tickets are $30.
4000 divided by $30 = 133
Not sure if this is correct but all the working and steps are correct! Hope this helps.
