Write an expression for the amount she added:
Dimes: 2(0.10)
Quarters: 3(0.25)
Nickels: 6(0.05)
Now write an expression for what she took out:
Quarters: 2(0.25)
Dimes: 5(0.10)
Now combine them:
2(0.10) + 3(0.25) + 6(0.05) - 2(0.25) - 5(0.10)
Simplify:
0.20 + 0.75 + 0.30 - 0.50 - 0.50
1.25 - 1.00 = 0.25 increase.
3 is the greatest common denominator
a is SSS, c is SAS and d is ASA, all good congruent triangle theorems.
b is AAA, good to show similar triangles, not necessarily congruent triangles.
Answer: b
Answer:3hr 2min and 5 second exact estimate would be 3 hr.
Step-by-step explanation: you divide 15 by 4.8. which is 3.12500. how many times can 60 go 125. it goes in 2 time. that gives me 2min. then 5 leftover so that would be the 5 seconds.
