Answer:
goldfish is 15 and guppies is 11
Step-by-step explanation:
Given data
let the number of goldfish be x
and the number of guppies be y
so
x+y= 25----------1
and
3x+4y= 86-------2
solve 1 and 2
x+y= 25
3x+4y= 86
from 1
x= 25-y
put this in 2
3(25-y)+4y= 86
75-3y+4y= 86
75+y= 86
y= 86-75
y=11
put y= 11 in 1
x+11= 26
x= 26-11
x= 15
Hence goldfish is 15 and guppies is 11

Since , radius is half of the diameter.
Therefore, radius of dartboard = (diameter) ÷ 2
= (4 inches ) ÷ 2 = 2 inches
Also, Formula for circumference : 
, where r is radius.
Now , Circumference of dartboard = 
Hence, The radius is 2 inches.

Answer: 11,700 times
Step-by-step explanation:
First find the number of seconds in 3 minutes 15 seconds.
Each minute is 60 seconds so 3 minutes would be:
= 3 * 60
= 180
Add the 15:
= 195 seconds
Lightning strikes more than 60 times per second so we shall use 60 times
= 60 * 195
= 11,700 times
