If Chris has finished 30% of an art project in 9 hours then he will take 30 hours to complete the whole work if he will work at same rate.
What is rate?A measure, quantity, or frequency, typically one measured against some other quantity or measure.
How to calculate time?Let the project contains 100 questions in total.
Chris finished 30% questions so he may finish 30 questions in 9 hours.
So in order to complete the 1 question he took =9/30 hours
In order to complete 100 questions he will take 9/30*100 hours which is equal to 30 hours.
Hence Chris will take 30 hours to complete the project.

As you can see, per each individual lap Leila runs faster.
However, this value could change over larger distances, therefore, I recommend you get them to run larger distances and compare their times.
Have A Nice Day ❤
-Millie
Answer:
Leila is the better runner.
Step-by-step explanation:
Velocity of Leila = (3×3/5)/(7/60) km/h
=15.42( approximately)
Velocity of Maria= (3/5)/(3/60)km/h
=12 km/h
So, as Leila is faster than Maria, she is the better runner.
Hope this helps

Help with my math i will mark brainliest
Answer:
D
Step-by-step explanation:
step 1: find the slope
slope is 2/-4 = -1/2
then plug in the value for x to y, you get +1 for the y intercept
then it becomes y=-1/2x + 1
I hope this answer helped, and if it was correct, please mark this as brainliest! Thank you!
Answer:
[tex]y=-\frac{1}{2} x+1[/tex]
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points
SO
[tex]\frac{y_{1}- y_{2}}{x_{1}- x_{2}} \\\\=\frac{2-0}{-2-2}[/tex]
[tex]=-\frac{1}{2}[/tex] this is your slope
so now your equation is [tex]y=-\frac{1}{2} x[/tex] but it isnt done yet if we plug in one of the points we will find the y- intercept.
SO we find our y-intercept is 1 so that makes our equation [tex]y=-\frac{1}{2} x+1[/tex]
Hope this helps!
Pls make brainliest :)

Answer:
(from top to bottom) Options 2 & 5
Step-by-step explanation:
Option 1: "...each player will get 4 slices of pizza, with 2 slices left over"
48/10 = 4.8
'4.8' meaning 4 pizza slices for each player w/ 8 slices left over.
THIS OPTION IS INCORRECT
Option 2: "...each player will get 4 slices of pizza, with no slices left over"
48/12 = 4
'4' meaning 4 pizza slices for each player w/ no left overs
THIS OPTION IS CORRECT
Option 3: "...each player will get 3 slices of pizza, with no slices left over."
48/15 = 3.2
'3.2' meaning 3 pizza slices for each player w/ 2 slices left over.
THIS OPTION IS INCORRECT
Option 4: "...each player will get 3 slices of pizza, with 3 slices left over."
48/15 = 3.2
'3.2' meaning 3 pizza slices for each player w/ 2 slices left over.
THIS OPTION IS INCORRECT
Option 5: "...each player will get 3 slices of pizza, with no slices left over."
48/16 = 3
'3' meaning 3 pizza slices for each player w/ no left overs.
