The diameter of B is 3 times the diameter of A.
So the linear scale factor is 3.
The area scale factor is, the linear scale factor squared.
So Area scale factor is: 3² = 9
To get the area of Circle B, just multiply the area of Circle A by the area scale factor:
Area of Circle B = 500 × 9
= 4500 metres squared

<span>You would do 125 mg + 62.5 mg + 25.25 mg
= 212.75
I am not an expert at math but I am 85% sure that is correct
and the quantity of the leftover original medication...
500 mg - 212.75 = </span><span>287.25</span>
Answer:
$20500
Step-by-step explanation:
26500-(.12*26500)=23320 For 1 year
23320-(.12*23320)=$20521.60 For 2 years
Answer:
P(yellow or red) =8/15
Step-by-step explanation:
There are 15 marbles, 3 green, 4 blue, and 5 red marbles.
3+4+5 = 12
That means there are 15-12 = 3 3 yellow marbles.
3 green,
4 blue
5 red
3 yellow
To find the probability of yellow or red, we add the number of yellow and red marbles together over the total number of marbles
P(yellow or red) = (yellow +red)/ total
= (3+5)/ 15
=8/15
