Humberto's displacement is 2 miles due south far from his starting point.
How is the displacement completed?We understand that displacement is a vector quantity with both magnitude and direction, while distance is a scalar quantity with only magnitude.
Displacement, unlike distance, shows the direction and position of an object from its original base. This means that displacement refers to how far an object has traveled out of its original position with the direction included.
In other words, displacement shows the object's overall change in position and the direction of the new position from the former.
Starting point = 0
Distance covered toward the north = 3 miles
Distance covered toward the south = 5 miles
Displacement = 2 (0 - 3 + 5) miles

Diana is packing a lunch that will include an orange. Diana has 3 navel oranges, 5 mandarin oranges, and 4 Valencia oranges. If Diana selects an orange at random, what is the probability that she selects a navel orange?
Give your answer as a simplified fraction.
Answer:
Step-by-step explanation:
1. Ok. Probability is something out of all. Add to get the bottom base of the probability.
3+4+5= 12
2. Probability is something out of something so 3 navel oranges can be represented out of 12 oranges.
3 out of 12
3. Make as fraction:
3 out of 12=
3/12=
1/4 or 25 Percent!
Answer: 1/4 or 25% ( If wanted as Percent)
Answer:
1/4
Step-by-step explanation:
Number of navel oranges = 3.
Number of mandarin oranges = 5.
Number of Valencia oranges = 4.
Let N be an event that Diana selects navel orange.
The total number of oranges Diana has:
n(T)=3+5+4=12n(T)=3+5+4=12
Number of navel Oranges is:
n(N)=3n(N)=3
The probability that Diana selects a navel orange is:
P(N)=n(N)n(T)=312=14P(N)=n(N)n(T)=312=14
Hence, the probability that Diana selects a navel orange is 1414.

Answer:

Step-by-step explanation:
a certain species of bird migrates 10,000 miles in 75 days a person race walking can walk 20 kilometers in 100 minutes
who goes faster
A person race walking a distance of 20 kilometers in 100 minutes is more faster with a speed of 0.2 kilometer per minutes.
How to determine who is faster?Mathematically, the speed of a physical object or body can be calculated by using this formula;
Speed = distance/time
Next, we would convert the unit of distance covered by the bird in miles to kilometers as follows:
1 mile = 1.60934 kilometer.
10,000 miles = X kilometer.
Cross-multiplying, we have:
X kilometer = 10,000 miles × 1.60934 kilometer.
X kilometer = 16,093.4 kilometer.
Also, we would convert the unit of time in days to minutes as follows:
1 day = 1,440 minutes
75 days = X minutes
Cross-multiplying, we have:
X minutes = 75 days × 1,440
X minutes = 108,000 minutes.
Now, we can calculate the speed of this bird as follows:
Speed = 16,093.4/108,000
Speed = 0.1490 kilometer per minutes.
For the speed of the person, we have:
Speed = 20/100
Speed = 0.2 kilometer per minutes.

A basic cellular package costs $40 /month for 60 minutes of calling with an additional charge of $0.20 /minute beyond that time. The cost function C(x) for using x minutes would be
If you used 60 minutes or less, i.e. if if x≤60 , then C(x)=40 (the base charge).
If you used more than 60 minutes, i.e. (x−60) minutes more than the plan came with, you would pay an additional $0.20 for each of those (x−60) minutes. Your total bill would be C(x)=40+0.20(x−60) .
If you want to keep your bill at $50 or lower for the month, what is the maximum number of calling minutes you can use?
Answer:
78
exclamation is that if 50 is lower than 60 which it is meaning that 78 is the correct answer if you multiply 18 + 34 that is not the right answer but there should be a right answer under this question you shouldn't trust me because I do not give a what the answer is I do not suggest you write down this answer but you do your top G
The maximum number of calling minutes you can use to keep your bill at $50 or lower is 110 minutes. If you use 110 minutes or less, your bill will not exceed $50.
To keep your bill at $50 or lower for the month, you need to set up an inequality using the cost function C(x):
C(x) = 40 + 0.20(x - 60)
Since you want to keep the cost at or below $50, the inequality is:
C(x) ≤ 50
Now, substitute the expression for C(x) into the inequality:
40 + 0.20(x - 60) ≤ 50
40 + 0.20x - 12 ≤ 50
0.20x + 28 ≤ 50
Now, isolate the term with "x" on one side by subtracting 28 from both sides:
0.20x ≤ 50 - 28
0.20x ≤ 22
Finally, divide both sides by 0.20 to solve for "x":
x ≤ 22 / 0.20
x ≤ 110
The maximum number of calling minutes you can use to keep your bill at $50 or lower is 110 minutes. If you use 110 minutes or less, your bill will not exceed $50.

By using trignometry we got the side p as 6.67
Use the cosine rule of trignometry to find side p
p² = r² + q² - 2rqcosP
To find the angle of p we will simply subtract angle R and angle Q from 180.
180 - 47.28 - 40 = 92.72
p² = 8² + 7² + 2(8)(7)cos(92.72)
p² = 107.685
p = √107.685
p = 10.38
Let's suppose that the shortest distance of R from PQ is .
look at the diagram I gave
since the line I made makes a right angled triangle, we can use SOH CAH TOA
for the angle 40, is opposite and 10.38 is hypotenuse
which means we will have to use SOH
sin40 = O/H
sin40 =x /10.38
0.6428 = x/10.38
0.6428 × 10.38 = x

The radius of the tire is 1.17 yards.
According to the question,
We have the following information:
A tire could roll 200 yards in 27.28 revolutions.
We know that the tire is in the shape of a circle.
We also that the following formula is used to find the circumference of the circle:
2πr where r is the radius of the circle
Now, we have the following expression:
2πr*27.28 = 200
54.56πr = 200
r = 200/54.56π
r = 200/54.56*3.14
r = 200/171.32

inequalities graphically and determine one possible solution.
The possible solutions are 8 hours and 9 hours.
The number of hours for lifeguarding is 8 hours.
The number of hours for clearing tables is 9 hours.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <

Less than and equal = ≤
Greater than and equal = ≥
We have,
Two summer jobs:
Lifeguarding.
x = number of hours
= $19 per hour
Cleaning tables.
y = number of hours
=$14 per hour
Total hours in a week = 17 hours
Minimum earning = $280
The inequality represents the above situation.
x + y ≥ 17
19x + 14y ≥ 280
Solving for x and y.
x + y = 17 _____(1)
x = 17 - y
19x + 14y = 280 ______(2)
Putting (1) in (2) we get,
19(17 - y) + 14y = 280
323 - 19y + 14y = 280
323 - 5y = 280
323 - 280 = 5y

A truck travels 50 m/s in a 30 second time frame what is the average speed
The average speed of the truck is 50 m/s .
We know that the average speed of any vehicle is calculated by total distance divide by total time.
Now the truck travels at 50 m/s for 30 seconds.
Distance covered in 30 seconds = 50 × 30 = 1500 meters
Time taken = 30 seconds
average speed = 1500 / 30 = 50 m/s
The average speed now accounts for the majority of the distance travelled. Average speed is essentially a method for calculating distance and the rate of transit time.
Knowing the average speed is crucial because it is clear that the pace will vary throughout the voyage. The average speed of a vehicle or an object can be determined using a variety of methods.
That is the most popular and simple way for figuring your average speed. It functions best when the object's speed remains constant throughout the journey, never rising or falling.
