The original price was 7.
Chloe got a 15% discount; this means she paid 100-15 = 85% of the price. Letting x be the price, Chloe paid 0.85x.
Denise got a 20% discount; this means she paid 100-20 = 80% of the price. Denise paid 0.8x.
We know that Chloe paid 35p more; this gives us the equation
0.85x = 0.8x + 0.35
We do not want a variable on both sides, so we subtract 0.8x from both:
0.85x - 0.8x = 0.8x + 0.35 - 0.8x
0.05x = 0.35
Divide both sides by 0.05:
0.05x/0.05 = 0.35/0.05
x = 7
Answer:
Step-by-step explanation:
Given
--- big circle
--- area of small circle
Required
Probability that a point selected lands on the small circle
Calculate the area of the big circle using;
Where
So, we have:
This gives:
The probability that a point selected lands on the small circle is calculated by dividing the area of the small cicle by the big circle
This gives:
Simplify
Any ratio simply takes the form (A/B)
Let throws = T , games = G
T = 36
G = 16
ratio of free throw to game = T/G
T/G = 36/16 = 9/4

(s o t)(x)=s(t(x))
(s o t)(-7)=s(t(-7))
x=-7→t(-7)=3(-7)→t(-7)=-21
(s o t)(-7)=s(t(-7))=s(-21)
x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439
(s o t)(-7)=s(t(-7))=s(-21)=-439
