Answer:
12. B , 13. 4
Step-by-step explanation:
Answer:
The mileage is 2,300 miles
Step-by-step explanation:
Let x be the number of miles driven.
<u>Primo:</u>
$47 per day
$0.30 per mile 
$0.30x per x miles.
Total cost 
<u>Ultimo:</u>
$26 per day
$0.95 per mile $0.95x per x miles.
Total cost 
If Ultimo charge is three times the Primo charge, then
Solve this equation:
Answer:
x=3 the angle is 48
Step-by-step explanation:
You know the total spam of the 2 angles combines is 112
set your formula as
112 = 64+16x
112-64=16x
48=16x
48/16 = x
3=x
When the exercise asks to describe the likelihood of the event using the probabilities means that taking into account that the probabilities are numbers between 0 and 1, see if the events are likely or not to happen.
For a soft drink, which has a 0.80 probability is a likely event that could happen because it is greater to the middle (0.5) but is not so close to 1.
For a daily special, which has a 0.25 probability is more and unlikely event that could still happen but its not so common to.
For dessert, which has a probability of 0.5 probability is neither a likely nor unlike event because the probability is really close to the middle.
For appetizer, which has a probability of 0.06 probability is more an unlikely/impossible event because the probability is so small and close to 0 that it is not common to happen at all.
Answer:
Part A
71°
Part B
The ladder is been used safely
Step-by-step explanation:
Part A
We solve the above question using Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = The distance between the house and the bottom of the ladder = 4 feet
Hypotenuse = Length of the ladder = 12 feet
x = Angle
Hence:
cos x = 4/12
cos x = 1/3
x = arc cos (1/3)
x = 70.528779366°
Approximately to the nearest degree
= 71°
Part B
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?
Angle x = 71°
Therefore, the ladder is been used safely
