Well just by looking at the question, if it is guaranteed to have a zero, and there are two answers, then wouldn't it be the 2nd and 3rd choices? I could be mistaken though.

Jeff can paint 28 sqaure feet every 30 mintues angela can paint 50 square feet every hour who can paint faster,and by how many s
Gnesinka [82]

Answer:

6/1 square feet per hour. Jeff can paint faster.

Step-by-step explanation:

So, to get Jeff's square feet to 60 minutes, you do 30x2= 60. So, you do that to 28. 28x2= 56. 56/1 is greater then 50/1. So 56-50= 6. Jeff can paint 6 square feet per hour, greater than Angela.

Hope this helped!

What is the surface area of a cube that is 4 cm on each edge?
icang [17]

Answer:

96 units squared

Step-by-step explanation:

The surface area of a cube can be written as 6 * (s^2)

s is the side length.

4^2 = 16.

6 * 16 = 96.

This is because the area of a cube is s^2.

There are 6 sides to a cube, so we multiply them.

Find the coordinates of the midpoint of CM with endpoints C(1, -6) and M(7,5).
Vilka [71]

Answer: The coordinates of the midpoint of CM with endpoints C(1, -6) and M(7,5) are (4,-\dfrac{1}{2}).

Step-by-step explanation:

We know that the coordinates of the midpoint(x,y) of line joining A(a,b) and B(c,d) is given by :-

(x,y)=(\dfrac{a+c}{2},\dfrac{b+d}{2})  .....(i)

Given : The coordinates of endpoints of CM are C(1, -6) and M(7,5)

Then , by using (i) , the coordinates of the midpoint of CM would be :-

(\dfrac{1+7}{2},\dfrac{-6+5}{2})\\\\=(\dfrac{8}{2},\dfrac{-1}{2})\\\\=(4,-\dfrac{1}{2})

Hence,  the coordinates of the midpoint of CM with endpoints C(1, -6) and M(7,5) are (4,-\dfrac{1}{2}).
