Answer:
Step-by-step explanation:
GIVEN: Emma started biking to the coffee shop traveling 
, after some time the bike got a flat so Emma walked the rest of the way, traveling 
If the total trip to the coffee shop took 
and it was 
away.
TO FIND: how long did Emma travel at each speed.
SOLUTION:
Let the distance traveled by Emma through bike is 
Total time taken when traveled by bike 
Distance traveled through feet 
Total time taken when traveled by feet 
Now,
Total time taken 
Distance traveled through feet 
Hence distance traveled using bike is 
and by feet is 
X^2 + y^2 -2y-11=0
x^2 + y^2 -2y=11
x^2 + y^2 -2y + ? = 11 + ?
x^2 + y^2 -2y + 1 = 11 + ?
x^2 + y^2 -2y + 1 = 11 + 1
x^2 + (y-1)^2 = 12

Answer:
60%
Step-by-step explanation:
First, find the total number of sixth graders
To do this, add the number of girls and boys together
girls+boys
There are 60 girls and 90 boys
60+90
150
Now, find the percent of sixth graders that are boys
To do this, divide the number of boys by the total number of sixth graders
boys/total sixth graders (part/whole)
There are 90 boys, and 150 total sixth graders
90/150
0.6
Convert to a percent. Multiply by 100 or move the decimal place two spots to the right
0.6*100=60
0.6-->6.0-->60.
So, 60% are boys
