Let n = number of months both have their services
Provider A:
C = 35.50n + 55
Provider B:
B = 35.50n
Provider A will always cost more than
provider B because of the $55 installation fee
Answer: 50 holes
Step-by-step explanation: I find an easy way to answer questions like this is by 'dimensional analysis'....
Dimensions mins/holes and mins
mins / (mins/holes) = holes (because 'mins' cancel out)
25 mins / (6 mins/12 holes) = 300/6 holes = 50 holes
Answer:
17
Step-by-step explanation:
I believe the answer is 17.
Simplify
17
=17
Now,
Consider point O at zero on the number line.
Mark a point A such at number 4 such that OA= 4
Draw a perpendicular AB at point A of unit length.
Join AB
Taking radius of length AB draw an arc to intersect the number line at C.
Finally, OC=\sqrt{17}
Thus proving the answer is 17 or 
Length of the rectangle
=
15
feet
Breadth of the rectangle
=
30
feet.
Explanation:
Let the breadth of the rectangle
=
x
So, the length of the rectangle
=
2
×
x
The perimeter given
=
90
feet
As per the formula for perimeter of a rectangle
Perimeter
=
2
×
(length + breadth )
90
=
2
×
(
x
+
2
x
)
90
=
2
×
(
3
x
)
90
=
6
x
x
=
90
6
x
=
15
So the length of the rectangle
=
15
feet, breadth of the rectangle
=
30
feet.
