Answer: 55.4 mins
Step-by-step explanation:
pragnesh and qazi = 2hrs
pragnesh and roghui = 3hrs
qazi and roghui = 4hrs
this means for every 1 hour they wold paint.
pragnesh and qazi = half of the fence
pragnesh and roghui =
qazi and roghui = quarter of the fence
time taken when they all work together
= + +
=
=
= 0.9231 × 60(mins)
= 55.4 mins
The branch of mathematics that deals with the collection, organization, analysis, and interpretation of numerical data.
10(6+2z)+8 distribute 10
60+20z+8 add like terms
68+20z is answer since you can’t simplify anything further

Step-by-step explanation:
Answer:
Center of circle: (1, -2)
Radius: √6
Step-by-step explanation:
First, we need to isolate the constant:
Then, we can divide the whole equation by 4:
Then, we can complete the square(reminder: (a+b)^2 = a^2 + 2ab + b^2)
Now that we got the standard equation of the circle, we can find the center and radius by using the equation , where (h, k) is the coordinate of the center, and r is the radius.
Therefore, the center of the circle is (1, -2), and the radius of the circle is √6.
