Answer:
<em><u>30 girls in the class</u></em>
Step-by-step explanation:
12 = 40%
12/40 = 1%
.3 = 1%
.3 * 100 = 100%
30 = 100%
30!
a) The function that represent this situation is y = 90 + 8x.
b) His weight be after 8 weeks is 154 lbs.
<u>Step-by-step explanation:</u>
It is given that,
- He started at 90 kilograms.
- And gained weight at a constant rate of 8 lbs a week.
a) Write a function to represent this situation. Use x and y as your variables.
- Let 'x' be the number of weeks he gained weight.
- Let 'y' be the total weight.
Hence the equation can be framed as,
Total weight = starting weight + weight gained in x weeks.
We know that, each week he gains 8 lbs. Therefore, for 8 weeks he gained 8x lbs of weight.
⇒ y = 90 + 8x.
∴ The function that represent this situation is y = 90 + 8x.
b) What would his weight be after 8 weeks?
To find his week after 8 weeks, substitute x=8 in the function y = 90 + 8x.
⇒ 90 + 8(8)
⇒ 90 + 64
⇒ 154 lbs.
∴ His weight be after 8 weeks is 154 lbs.
Answer:
20 minutes
Step-by-step explanation:
70 minute classes times 3
Plus 2 breaks one in between 1st and 2nd class
And another in between 2nd and 3rd class
Which = 220 minutes
4 hours times 60 (because 60 minutes per hour)
Gives us 240 minutes
Then you subtract total time from time in classes and breaks
Which gives us 20 minutes for lunch time
