Answer:
6840
Step-by-step explanation:
Well we know there's 24 hours in a day so dividing that by 1440 we get 60. Now we know that it consumes 60 watts ever hour. so now we just have to figure out how many hours there are and times that by 60. So there are 96 hours in 4 days plus 28=114. So times that by 60 ( watts) 114×60=6840
So that's your awnser.

Answer:
Rhombus
Step-by-step explanation:
The given points are A(−5, 6), B(−1, 8), C(3, 6), D(−1, 4).
We use the distance formula to find the length of AB.
The length of AD is
The length of BC is:
The length of CD is
Since all sides are congruent the quadrilateral could be a rhombus or a square.
Slope of AB
Slope of BC
Since the slopes of the adjacent sides are not negative reciprocals of each other, the quadrilateral cannot be a square. It is a rhombus
X^2 + y^2 -4x27 (the numbers in bold means the multiplying a negative and a positive equals a negative)
x^2 + y^2 -(4x27) = x^2 + y^2 -108
Answer:
Step-by-step explanation:
Given that there are two machines available for cutting corks intended for use in wine bottles.
X1 = diameter of I machine and X2 = diameter of II machine
X1 is N(3.04, 0.02) and X2 is N(2.9, 3.1)
Acceptable is mean =3 and std dev = 0.1
a)
b)
Both are certain events.
