Answer:
Part A: pennies are 40% of the jar
Part B :
Nickels: 10
Quarters: 20
Pennies: 20
Step-by-step explanation:
Part A: since the nickels and quarters make up 60% of the jar the pennies make up the other 40%.
Part B:
Nickels: 20 percent of 50 (the amount of coins in the jar) is 10
Quarters & Pennies (since they have the same percentage): 40 percent of 50 is 20
Part A: 40% are pennies
Part B: NIckels 10, Quarters 20, Pennis 20
A not similar
These triangles are not similar
<K would have to equal either angle E or D since angle F equals angle F
E = 50 and D = 58 and K = 49 so K does no equal E or D so they cannot be similar
289
a^2 x b^2 = c^2
a = 8 b= 15 c = s
64 + 225 = 289
square root 289 = 17
