Answer:
OW = 8
Step-by-step explanation:
It states that WC is a tangent to the circle. The line OW is the radius of the circle that meets the tangent, the circle theorem rule is that the angle a tangent makes to a radius of a circle is 90°. So angle CWO is 90°. This makes triangle CWO a right angle triangle.
Now we can use Pythagoras theorem to find the value of OW.
In the theorem c is the longest side of a right angled triangle and a and b are the smaller sides:
c² = a² + b²
So we can rearrange the equation to find on of the smaller sides:
a² = c² - b²
OW² = 17² - 15²
OW² = 289 - 225
OW² = 64
OW = √64
So OW is 8.
1/2 is equal to 2/4
2/4 plus 1/4 is 3/4
meaning that the remaining is 1/4=6
so if 1/4 is 6, then we have to multiply 6 by 4
6×4=24

Apple: £20
Banana: £60
I believe this is the answer because between the two problems there is a difference of £60. So I saw three apples were gone from the next so 60 divided by 3 is 20. Then we need to find the banana price. 20 x 7 = 140. 200 - 140 is 60. So the banana is 60 and the apples are 20.
