Answer:
12 hours
Step-by-step explanation:
36 divide that by 12 and she has 12 hours to write on 36 pages
Step-by-step explanation:
(72)¹⁴³ ≡ x (mod 7)
Since 72 ≡ 2 (mod 7),
72³ ≡ 2³ (mod 7) ≡ 1 (mod 7).
Therefore (72)¹⁴³ = (72³)⁴⁷ * (72²)
≡ 1⁴⁷ * 4 (mod 7) ≡ 4 (mod 7).
The answer is A.
Answer:
Therefore the approximate area of this clock face is 415.3 feet².
Step-by-step explanation:
Given:
Clock is of Circular Shape,
Diameter = 23 feet
To Find :
Area of Clock Face = ?
Solution:
Area of Circle having Radius 'r' is given as,
Substituting the values we get
Therefore the approximate area of this clock face is 415.3 feet².
Given parameters:
Equation of the line is y = - + 8
Unknown:
Slope of line parallel to this line = ?
Slope of line perpendicular = ?
Solution:
A line parallel to this line will have the same slope with it.
A line perpendicular will have the negative inverse of this slope;
Slope of line = -
Slope of line parallel to this line =
Slope of line perpendicular = negative inverse = -( -()) = 2
So, the slope of line parallel to this line is - 1/2 and that perpendicular is 2
