To do this, you'll have to get loris and doris to the same amount of time, we can already tell loris makes 40 bracelets in 100 minutes but we are still missing 20 minutes, so we got to do some math(Ofc we do its mathematics) if you divide 50 by 20 you'll get 2.5 which is how many minutes it takes to make a bracelet. So now we can go back to that missing 20 minutes, if you divide 20 by 2.5, you'll get 8. So in 2 hours loris makes 48 bracelets(20 + 20(50 hours each)=40 + 8(the missing 20 minutes) = 48) But here is the tricky part it says per an hour, so we need to reduce both by half, so loris makes 24 bracelets an hour and doris makes 22 bracelets an hour so loris makes 2 more bracelets and hour than doris... hope i've helped!
Answer: $2,561.50
(I = A - P = $211.50)
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 18%/100 = 0.18 per year.
Solving our equation:
A = 2350(1 + (0.18 × 0.5)) = 2561.5
A = $2,561.50
The total amount accrued, principal plus interest, from simple interest on a principal of $2,350.00 at a rate of 18% per year for 0.5 years is $2,561.50.
I say 3 if I’m wrong sorry
1 hour and 48 minutes plus 1980/550=3.6 so 3 hours and 36 minutes plus 30 minutes so 48+30=1 hour and 18 minutes plus 1 hour = 2 hours and 18 minutes + 3 hours and 36 minutes =5 hours and 54 minutes hope I helped
Answer:
a)The quantity (mg) of medication used to the nearest hundredths is 212.75mg
b) The quantity (mg) of the original medication left in the stock bottle to the nearest tenths is 287.3 mg.
Step-by-step explanation:
For question a) 125mg + 62.5mg +25.25mg= 212.75 mg to the nearest hundredths
b) The quantity left can be calculated by subtracting 212.75 from 500
500 - 212.75 = 287.25 to the nearest tenth is 287.3mg
