Δ ABC is an isosceles triangle in which the two base angles are equal.  A such 3x = 75°.

Now, since the sum of the angles in a triangle is 180°,
 then (4y + 10)° + 75° + 3x = (4y + 10 + 75 + 75)° = 180°
⇒   (4y + 10 + 75 + 75)° = 180°
                           4y = 180° - 160°
                             y = 5°

Find the diameter of a circle with an area of 226.98
andrey2020 [161]
Remember the formula of the area of a circle is:
V =  \pi * r^{2}
SO given that
V = 226.98
and \pi = 3.14
Plug in a chug
226.98 = 3.14 * r^{2}
r^{2}=  72.287
r = 8.50

Remember that d = 2 * r
d = 2 * 8.5 = 17

I really need help pls helppp meee
zhenek [66]

Answer:

2.50t + 350 = 3t + 225

Step-by-step explanation:

Let t represent the number of tickets that each class needs to sell so that the total amount raised is the same for both classes.

One class is selling tickets for $2.50 each and has already raised $350. This means that the total amount that would be raised from selling t tickets is

2.5t + 350

The other class is selling tickets for $3.00 each and has already raised $225. This means that the total amount that would be raised from selling t tickets is

3t + 225

Therefore, for the total costs to be the same, the number of tickets would be

2.5t + 350 = 3t + 225
