Drag one model next to each situation. The correct model for each group represents that situation
The question involves creating and analyzing scientific models, collaborating in groups to build and refine these models based on experimental evidence, and engaging in critical thinking about their accuracy and limitations.
Explanation:The question involves students creating and analyzing models that represent certain scientific situations. Creating a model is a fundamental part of scientific inquiry as it helps in visualizing and understanding complex concepts. Students are tasked with exchanging and labeling pictures or drawings of their models, which aids in the development of the communication of scientific ideas. They then apply their models to specific situations, test these models, and note the outcomes to assess the accuracy and limitations of the models they have built. This process involves critical thinking, collaboration, and application of scientific knowledge.
Moreover, students are required to modify their models based on experimental evidence and discussions about the limitations of their models. When building models of atoms, for example, students must consider basic ratios, an understanding of atomic structure, and the unique characteristics of the element they are representing.
The complete question is:Drag one model next to each situation. The correct model for each group represents that situation
Who does this describe? The country was in chaos, but this scholar helped bring order to society through his teachings about family and government relationships, and the Golden Rule.
A. Siddhartha Gautama
B. Ramayana
C. Asoka
D. Confucius
Answer:
The correct answer is D. This statement describes Confucius.
Step-by-step explanation:
Confucius was a Chinese philosopher, whose teachings had a great influence in China, Korea, Japan and Vietnam. According to tradition, he was born in the city of Qufu, in the Kingdom of Lu, now part of Shandong Province. He is said to have become Minister of Justice in Lu's kingdom. After being forced to resign, he toured the small kingdoms of northeast and central China, explaining his ideas about governance.
He emphasizes his philosophy of morality, right social relationships, justice and honesty, both in personal life and in government. During the Han Dynasty period in China, his teachings became the official philosophy of the state. His teachings were introduced to Europe by the Jesuit Matteo Ricci, the first to Latinize his name as "Confucius."
A wild horse runs at a rate of 8 miles per hour for 6 hours. Let yy be the distance, in miles, the horse travels for a given amount of time, xx, in hours. This situation can be modeled by a function. Which of these describe the domain of the function? Group of answer choices 0\le x\le60≤x≤6 0\le y\le60≤y≤6 0\le x\le480≤x≤48 0\le y\le480≤y≤48
Answer:
[tex]0\leq x\leq 6[/tex]
[tex]0\leq y\leq 48[/tex]
Step-by-step explanation:
we are given
speed =8 mph
time = 6 hours
so, we have
[tex]x=6[/tex]
now, we can find distance
distance = (speed)*(time)
[tex]distance=8\times 6 miles[/tex]
[tex]distance=48 miles[/tex]
so, we have
[tex]y=48 miles[/tex]
so, our range for x and y can be
[tex]0\leq x\leq 6[/tex]
[tex]0\leq y\leq 48[/tex]
In ?ABC, the measure of ?C=90°, the measure of ?A=30°, and CA = 68 feet. Find the length of BC to the nearest foot
Answer:
39 feet
Step-by-step explanation:
Since the triangle is right we can use the tan ratio to find BC
tan 30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{68}[/tex]
multiply both sides by 68
68 tan 30° = BC ⇒ BC ≈ 39 feet ( to nearest foot )
The table shows the value of an account x years after the account was opened. Based on the exponential regression model, which is the best estimate of the value of the account 12 years after it was opened? $8,910 $8,980 $13,660 $16,040
Answer:
Correct choice is B
Step-by-step explanation:
The exponential regression model can be written as exponential function
[tex]y=a\cdot b^x.[/tex]
Then
[tex]5,000=a\cdot b^0=a,\\ \\5,510=a\cdot b^2\Rightarrow 5,510=5,000\cdot b^2,\\ \\b^2=\dfrac{5,510}{5,000}=\dfrac{551}{500}\Rightarrow b\approx 1.05.[/tex]
Thus,
[tex]y=5,000\cdot (1.05)^x.[/tex]
When [tex]x=12,[/tex] you get
[tex]y(12)=5,000\cdot (1.05)^{12}\approx \$8,980.[/tex]
At 55 mph it will take you approximately _____ feet to stop the car. A. 5 feet B. 100 feet C. 228 feet
Answer:
The correct answer is option C, 228 feet
Step-by-step explanation:
As per Newton’s third law of motion:
V2 – U2 = 2 x a x S
Where V = final velocity
U = Initial Vlocity
a = acceleration (-ve)
S= distance travelled
V= 0 mph
U= 55 mph = 80.6667 ft /sec
0 – (80.6667 ft /sec)2 = 2 x (-g/2) x S
S = (80.6667 ft /sec)2 /(32.2 feet per second per second x0.5)
S = 202.1 feet
So the most nearest option is option C
Carolina is mowing lawns for a summer job. For every mowing job, she charges an initial fee plus \$6$6 for each hour of work. Her total fee for a 44-hour job, for instance, is \$32$32. Let F(t)F(t) denote Carolina's fee for a single job FF (measured in dollars) as a function of the number of hours tt it took her to complete it.
Answer:
y=8+6t
Step-by-step explanation:
Answer:
[tex]F(t)=6t+8[/tex].
Step-by-step explanation:
Let t represent number of hours.
We have been given that Carolina charges $6 for each hour of work. So amount charged for t hours of work would be [tex]6t[/tex].
Let us find initial cost by subtracting charges for 4 hours from 32 as:
[tex]\text{Initial cost}=32-4\times 6[/tex]
[tex]\text{Initial cost}=32-24[/tex]
[tex]\text{Initial cost}=8[/tex]
The total cost for t hours of work would be initial cost plus cost per hour: [tex]6t+8[/tex].
Our required function would be [tex]F(t)=6t+8[/tex].

The bike shop is having a sale. Everything in the store is 20% off. A bike is originally priced at $345.00 What is the sale of the bike? Enter your answer in the box.
To find the sale price of a bike originally priced at $345.00 with a 20% discount, calculate the discount amount ($69.00) and subtract it from the original price, resulting in a sale price of $276.00.
Explanation:The bike shop is having a sale where everything in the store is 20% off. To calculate the sale price of a bike that is originally priced at $345.00, you first need to determine the discount amount. Convert 20% to a decimal by dividing 20 by 100, which gives you 0.20. You then multiply the original price of the bike, $345.00, by 0.20 to find the discount amount.
$345.00 \times 0.20 = $69.00
Next, subtract the discount from the original price to find the sale price.
$345.00 - $69.00 = $276.00
Therefore, the sale price of the bike is $276.00.

There are 100 sophomores at the school. 85% of them are good students. What would be the percent of good students at school if (rounding the answer to the nearest whole number): b ten "A" students were to join this school
Answer:
86%
Step-by-step explanation:
77% students are good students after 10 students join the school.
What is percentage?Percentage is a part of the whole number. It is denoted by % sign.
1 %= 1/100.
Given that,
The number of sophomores in the school = 100
Also, the percentage of good students = 85%
So, number of good students = 100x85/100 = 85
If 10 students join the group,
Then total number of students = 100+10 =110
Percentage of good students = 85 x 100/110
= 77.181
= 77%(round to whole number)
The percentage of good students is 77% in school.

How to get 5% of 220 files
To find 5% of 220 files, convert the percentage to a decimal (5/100 = 0.05) and multiply it by 220. The result is 11, meaning 5% of 220 files is 11 files.
To calculate 5% of 220 files, you need to use the concept of percentage from basic mathematics. Here's a step-by-step explanation:
Understand that 'percent' means 'per hundred'. So, 5% can be expressed as 5/100.
Multiply the percentage (in this case, 5/100) by the total number of files (which is 220).
Perform the calculation: (5/100) times 220 = 0.05 times 220 = 11.
Therefore, 5% of 220 files is 11 files.
How are the absolut value of an imaginery number is related distance betweem two point related to another
Answer:
the absolute value of a imaginary number is somewhat similar to a distance between the two points.
Step-by-step explanation:
by absolute value of an imaginary number a+i b we mean the distance of the origin (0, 0) and the point (a,b) in the complex plane
i.e. [tex]\sqrt{a^{2} +b^{2} }[/tex]
whereas distance between two points ([tex]x_{1}[/tex],[tex]x_{2}[/tex]) and ([tex]y_{1}[/tex],[tex]y_{2}[/tex]) is given by [tex]\sqrt{(x_{1}-y_{1} )^2+( x_{2}-y_{2})^2}[/tex]
if ( [tex]y_{1}[/tex],[tex]y_{2}[/tex])=(0,0) then it is similar to the absolute value of a complex number of the type x+i y.
ughhhh please help me i don’t wanna fail again
Answer:
Step-by-step explanation:
Start with (1,2) . One of the pairs has to begin with a 1. Look around to see which set of points has a 1 for the x value.
B and C do. So all you have gotten rid of is A and D. D looks like it might work, but it really does not. It has - 1 as it's starting point. The point must start with 1.
The next step is to find the distance between the 2 given points. The y value for the two points already on the graph is the same so they do not contribute anything to the distance. -3 and 1 are 4 units apart.
1 and ? must also be 4 units apart. Only D does. 1 and -3 are the x values 2 and 6 are the y values. The answer is B
is 2i a real or complex root?
By definition, i = sqrt(-1) because it is used to solve the equation x^2+1 = 0 or x^2 = -1, which has no real number solutions.
Since i is imaginary or complex, then so is 2i
You can express it as 2i = 0+2i to be in the form a+bi with a = 0 as the real part and b = 2 as the imaginary component.
wanda has $640 in her checking account. she pays her landlord $75 per week for rent.
which function best models the linear relationship?
y = 640x 75
y = −75x 640
y = −75x − 640
y = 75x 640
Answer:
Option B is correct
[tex]y = -75x+640[/tex]
Step-by-step explanation:
The equation of line is given by:
[tex]y=mx+b[/tex]
where, m is the rate or slope and b is the initial amount.
As per the statement:
Wanda has $640 in her checking account.
She pays her landlord $75 per week for rent.
Assume that the number of weeks be x.
Let us assume that the y represented the money in the account after x weeks.
then;
the function becomes,
[tex]y = 640-7x[/tex]
or
[tex]y = -75x+640[/tex]
Therefore, the function best models the linear relationship is, [tex]y = -75x+640[/tex]

DEFG is a parallelogram. Segment DH = 2y + 6, segment HF = 4x + 1, segment HE = 3x + 2 and segment GH = 20. Find the value of x
Answer:
6
Step-by-step explanation:
If GH equals 20 so does HE so 3x6+2=20
Answer:
x=6
Step-by-step explanation:
given that DEFG is a parallelogram and the diagonals bisect at H.
Since diagonals bisect each other in a parallelogram, we have
DH = HF and EH = HG.
GH=20 is given. i.e. 3x+2 = 20
Subtract 2
3x = 18
Divide by 3
x =6
so answer is x =6.
We can find value of y also. DH =HF=4x+1
i.e. 2y+6 = 25
y = 9.5
