Step-by-step explanation:
$3.75 because each apple costs 75 cents and if you multiply it by 5 you get 3.75
Answer:
6
Step-by-step explanation:
Draw line segments ST and RQ. Triangle RUQ and SUT are similar, because they are in a circle. Now, you use similar triangles to get that QU/UT=RU/SU so 2 = 12/SU so SU = 6, or y = 6.
Note: This is generealized by the Power of a Point, which states that if you have two chords that intersect, then you can do the same thing and it will show that QU*SU=RU*TU. (You can change the variables but the similar triangles stay the same).
By using a^2 + b^2 = c^2 we plug that in and get 9+x^2= 25
25-9 is 16
The square root of 16 is 4
Answer is 4
To check, plug it back in you get
9+16=25
