Mathematics
1 answer:
solniwko [45]3 years ago
7 0

Step-by-step explanation:

We're going to convert all of these to km/h.

Sapons: 80km/2h => <u>40kmh</u>

Silvers: 180km/3h => <u>60kmh</u>

Johns: <u>50kmh</u>

Cunninghams: (to get the 30 mins to 60 mins, multiply the top and the bottom by 2) 35km/30min => <u>70kmh</u>

Now that they're all in the same form we can put them from least to greatest.

Answer:

(Least) - Sapons

- Johns

-Silvers

(Greatest) - Cunninghams

Bianca took a job that paid $150 the first week. She was guaranteed a raise of 6% each week. How much money will she make in all
ivann1987 [24]

Answer:

$225.54 (hope it help)

Step-by-step explanation:

for 2nd week

$150 for the first week and a raise of 6% each week

which means 150+6%

6% of 150 is 9 (150x0.06)

150+9=159

and it repeats

for 3rd week

6% of 159 is 9.54 (159x0.06)

159+9.54=168.54

for 4th week

6% of 168.54 is 10.1124 (168.54x0.06)

168.54+10.1124=178.652

for 5th week

6% of 178.652 is 10.71912 (178.652x0.06)

178.652+10.71912=189.37112

an easier to do it is to just do 178.652 + 6% on your calculater

and I'll skip all the way to the 8th since you know the formula

212.777390432+6%=225.544033858

225.544033858≈225.54
