Answer:
C. 3.33 hours
Step-by-step explanation:
Use the algebra work equation:
=
+
, where tb is the time to work together, t1 is the time it takes one person, and t2 is the time it takes the other person
Plug in the values we know:
=
+ 
=
+ 
= 
20 = 6tb
3.33 = tb
So, it would take them 3.33 hours when working together.
So the unit rate is basically how many ounces in 1 cup?
So since there are 64 ounces in 8 cups, you can just divide by 8, to find how many sets of 8 there are in 64.
64 = 8
64 / 8 = 8 / 8
8 = 1
So there are 8 ounces in 1 cup, which is your unit rate.
Answer:
1/3 you will add it to get your main description and get your final answer
Answer:
Option 4: (x+1)^2+(y-1)^2 = 16
Step-by-step explanation:
The radius of the given circle in attached picture is: 4 units
The center is denoted by (h,k) = (-1,1)
So,
The standard form of equation with center at (h,k) and radius r
(x-h)^2 + (y-k)^2 = r^2
Putting the values
(x-(-1))^2 + (y-1)^2 = 4^2
(x+1)^2+(y-1)^2 = 16
Hence option number 4 is correct ..
