Answer:
20 helmets were sold ($500)
4 bikes were sold ($2000)
Step-by-step explanation:
Bikes: $500 each, helmets: $25 each
Ratio of helmets to bikes 5:1, or $125:$500, which totals to $625
$2500 ÷ $625 = 4
5:1 x 4 = 20:4
$125:$500 x 4 = $500:$2000
6 segments can be drawn with a 4 point line .
The diagonal should be 31.2* the square root of 2 it’s the ratio of the sides of the 45 45 90 triangle formed when you divide a square in diagonal halves.
Basically you do 2+0 except it stays negative because the bigger number is negative and there is no positive number added.
