Answer:
D
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
Here r = 15, thus
x² + y² = 15² , that is
x² + y² = 225 → D
Answer:
$24
Step-by-step explanation:
Inversely proportional means that the two variables (price and weight in this case) will always have the same product. Therefore, we can write the following equation:
25 * x = 20 * 30 (where x is the price of a 25 oz. racquet)
25x = 600
x = $24
Answer:
5.5
Step-by-step explanation:
B is the midpoint of AC, D is the midpoint of CE
This means that CE = 1/2 AE
CD = 1/2 ( 11)
CD = 5.5
It would be 57 minutes. Also love the Kenma profile picture!!
EXPLANATION: so 4:48 is almost an hr to 5:45. Just subtract 3minutes from an hr and you have your answer!
55x + 10 = 57x....where x = number of months
10 = 57x - 55x
10 = 2x
10/2 = x
5 = x.....they will cost the same at 5 months...they will each cost $ 285 at 5 months
