Answer:
160 miles
Step-by-step explanation:
Company A form $130 a day plus $0.30 per mile
Company A = 130 + 0.30x
Company B charges $50 a day plus $0.80 per mile
Company B = 50 + 0.80x
Where,
x = number of miles
Equate the cost of company A and company B
130 + 0.30x = 50 + 0.80x
Collect like terms
130 - 50 = 0.80x - 0.30x
80 = 0.50x
Divide both sides by 0.50x
x = 80 / 0.50
= 160
x = 160 miles
The number of miles in a day at which the rental costs for Company A and Company B are the same is 160 miles
{(5,3) , (6,1), (7,-1), (8,-3)}
inverse of (x,y) is (y,x)
inverse of { (3,5), (1, 6), ( -1, 7), (-3, 8)} is
Answer: G and F are mutually exclusive because they cannot occur together
According to the definition of mutually exclusive events,
The events which can not occur together and probability of them occurring together is 0 are known as mutually exclusive events.
The first statement gives an implication that if one happens then other happens meaning they could both still happen so it is not true.
The second statement contradict the question about being mutually exclusive events.
The third statement also is a implication that if one event occurs then other does or does not occur.
The last statement is correct one that conforms with the question and obeys the definition of mutually exclusive events.
where is the question?
Answer: the shortest side is 279.24 feet
The diagram of the triangle in shown in the attached picture. The given angles of 30 degrees and 50 degrees are for the shorter sides.
Since the sum of angles in a triangle is 180 degrees, it means that the angle of the longer side, x will be
x = 180 - (30 + 50)
x = 180 - 80 = 100 degrees
The sine rule states that
a/sinA = b/sinB = c/sinC
c = 550
a = the shortest side.
Therefore
a/sinA = c/ sinC
a/sin30/= 550/sin100
asin100 = 550sin30
0.9848a = 550×0.5 = 275
a = 275/0.9848
a = 279.24 feet
