Answer:
9.2
Step-by-step explanation:
Use law of sines
a/sinA = b/sinB
5/sin 31 = b/sin 108
b=9.2
Part A you can figure out that the car is traveling at 50 miles an hour because after every hour the distance decreases by 50
b the average change is 100 miles for every 2 hours, which can be simplified back to 50mph which represents the speed of the car
part C {y=-50x+900| (0,900),...(18,0)
Answer:
Median = 116.
First quartile = 102.
Step-by-step explanation:
There is a total of 280 scores so the median will be the 140th score.
The first box gives 26 , second 34 = 60
The 3rd box contains 100 giving a total of 160 so the median lies in this third box.
140 - 26 - 34 = 80..
That gives a value of 80 / 5 = 16.
The median is 100 + 16 = 116.
The lower quartile is the 70th score
26 + 34 + 10 = 70.
So it is 100 + 10/5 = 102.
Answer: The pupil's area is π mm^2 or 3.14mm^2
Step-by-step explanation:
First of all, the pupil is the name that is given to the hole that is situated in the centre of the Iris of the human eye which allows light to come in contact with the retina. It adjusts in size (diameter) depending on the availability of light in the environment we find ourselves.
In this scenario, Shannon entered the room with unusual lighting and her pupil's diameter adjusted to 2 millimeters.
Now, it is important to note that a pupil is an example of a circle.
The formula for finding or calculating the area of a circle is πr^2, where π = 22/7 and "r" = radius.
Since the radius of her pupil is = 2/2 = 1 millimetre, the area of the pupil is:
πr^2 = π × 1 × 1 = π mm^2
Or 22/7 × 1 × 1
= 3.14mm^2
Therefore the area of her pupil when she entered the room with unusual lighting is 3.14mm^2
