Answer:
3:30PM
Step-by-step explanation:
Martina starting playing video games as soon as she got home from school. She played video games for 15 minutes. Then Martina helped clean the kitchen for 45 minutes. After the kitchen was clean, it took Martina 15 minutes to finish her homework. When Martina finished her homework, it was 4:45 P.M. What time did Martina get home from school?
Step 1
We add up the minutes it took her to do things
= Minutes for video games + Minutes for cleaning the kitchen + Minutes for doing homework
= 15 minutes + 45 minutes + 15 minutes
= 75 minutes
= 1 hour 15 minutes
Step 2
When Martina finished her homework, it was 4:45 P.M. What time did Martina get home from school?
This is calculated be subtracting 1 hour 15 minutes from 4:45 PM
= 4:45 PM - 1 : 15
= 3:30PM
Therefore, Martha got home from school by 3:30 PM

Answer :
and ![(x+1)^2+(y-1)^2=16](https://tex.z-dn.net/?f=%28x%2B1%29%5E2%2B%28y-1%29%5E2%3D16)
Step-by-step explanation:
Given : A circle with the same radius as the circle shown but with a center at (-1.1).
To find : Which equation represents a circle ?
Solution :
The equation of a circle with center (h,k) and radius r is given by :
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
Here, we are given (h,k)=(-1,1)
and radius r=4 units
So, equation of circle will be :
![(x-(-1))^2+(y-1)^2=4^2](https://tex.z-dn.net/?f=%28x-%28-1%29%29%5E2%2B%28y-1%29%5E2%3D4%5E2)
![(x+1)^2+(y-1)^2=4^2](https://tex.z-dn.net/?f=%28x%2B1%29%5E2%2B%28y-1%29%5E2%3D4%5E2)
or ![(x+1)^2+(y-1)^2=16](https://tex.z-dn.net/?f=%28x%2B1%29%5E2%2B%28y-1%29%5E2%3D16)
Therefore, the required equations of circle are
and ![(x+1)^2+(y-1)^2=16](https://tex.z-dn.net/?f=%28x%2B1%29%5E2%2B%28y-1%29%5E2%3D16)
What question is that from? I'm talking about ur grade
Answer:
16/3 or 5.33
Step-by-step explanation:
Cross multiply
4/1 * 3/4
4 * 4 = 16
3 * 1 = 3
