X= 147
Y= 64
They’re similar which means they’re enlarged so therefore the angles are unaffected
diagonal = 9√2 ≈ 12.73
the diagonal splits the square into 2 right triangles with the hypotenuse being the diagonal of the square
using Pythagoras' identity
d = √(9² + 9²) = √162 = 9√2 ≈ 12.73 ( to 2 dec. places )
Answer:
Pattern seen is arithmetic progression. The both equations are same.
Step-by-step explanation:
a.The given pattern is 8,12,16,20,24....We can see that the difference between any two consecutive terms is 4.Therefore this is an AP(arithmetic progression).
b.Percy's equation , 
⇒
⇒
⇒
which is the same as Stella's equation . So , we can see that both equations are the same.
Answer:
45
Step-by-step explanation:
first create a proportion.
40/100 = 18/x
you're trying to find x, the original price, so to find x you'll need to cross multiply. 18 times 100 divided by 40, which is 45.
The original price was $45
