Step-by-step explanation:
If AB is a tangent then ∠ ABC = 90° and Δ ABC is right
Using the converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides.
15 is the longest side and 15² = 225
9² + 12² = 81 + 144 = 225
Thus Δ ABC is a right triangle at B
Thus AB is a tangent to the circle at B
I’m confused, can you explain
Answer:
I dont know but combine like terms and then solve it will make It alot easier
1. So, since Manuel bought 9 pounds and ate 3/4 of 1 pound, he has 8.25 pounds left (9 - 0.75 = 8.25)
2. Let us call "x" the cost of 1 pound of apples
3. (8.25) * (x) = $15
4. x = $1.81818 rounded to the nearest dollar is $2 / pound
Answer:
Step-by-step explanation:
4/9 to 20/x
cross multiply and divide to get your answer
4 20
9 x
4x=180
x=45
