Answer:
b = 9cm is the answer.
Step-by-step explanation:
a = 12cm
b = ?
c = 15cm
By using the Pythagoras theorem,
a² + b² = c²
12² + b² = 15²
144 + b² = 225
b² = 225 - 144
b² = 81
b = 9cm.
∴ b = 9cm is the length of the missing leg.
You can set up an equation for this. if x is the amount of weeks, and m is total money, then it'd be
500+75x=m
plug numbers in
3 weeks: 500+75*3=$725
10 weeks: 500+75*10=$1250
6 months, each month having 4 weeks, is 24 weeks
500+24*75=$2300
They both have the same amount of cookies, 8.3 and 8.30 are the exact same number. One just doesn’t have a zero at the end of it.
