The graph below models the late fee for overdue books at the library what is the unit rate for the cost of an overdue book at this library?
A)$2 per day
B)$4.50 per day
C)$0.50 per day
D)$1 per day
Answers
Answer:
The answer is C. $0.50 per day .
Hope this helps
Option C is correct, $0.50 per day is the unit rate for the cost of an overdue book at this library.
The unit rate is the cost per one unit of a given quantity.
In this case, it's the cost of an overdue book per day.
In the given graph models the late fee for overdue books, you can find the unit rate by identifying two points on the graph and calculating the slope between those points.
Suppose you have two points on the graph: (x₁, y₁) and (x₂, y₂), where x represents the number of days the book is overdue, and y represents the corresponding late fee in dollars.
The formula for calculating the slope (m) between two points is:
m = (y₂ - y₁) / (x₂ - x₁)
Let us take two points from graph: (4, 2) and (6, 3)
Unit rate = 3-2/6-4
=1/2
=0.5
Hence, $0.50 is the unit rate for the cost of an overdue book at this library. Option C is correct.

Which equation is equivalent to y=2/3x-6
A. 2x+3y=-6
B.3x-2y=6
C.3x-2y=12
D.2x-3y=18
Answers
Answer:
D. 2x-3y=18
Step-by-step explanation:
1. multiply both sides by 3 to get rid of the fraction
( 3)(y)=([tex]\frac{2}{3}[/tex]x -6)(3)
2. That gives 3y=2x-18
3. subtract 2x on both sides
3y=2x-18
-2x = -2x
3. that gives -2x+3y=-18
4. then multiply by -1 to make 2x positive
-1(-2x+3y=-18)
5. and that gives 2x-3y=18

Humans shed about three million particles of skin every five hours. Humans can shed about fifty thousand particles of skin every five minutes. The approximate number of particles of skin a human can shed in five hours can be written in the form a times 10^b, where a is 3 and b is __
Answers
Answer: The approximate number of particles of skin a human can shed in five hours can be written in the form a times 10^b, where a is 3 and b is 6 .
Step-by-step explanation:
Given: Humans shed about 3million particles of skin every 5 hours.
Since, 1 million = 1,000,000
Then 3 million = 3 x 1 million
[tex]= 3 \times1,000,000[/tex]
[tex]= 3,000,000[/tex]
[tex]=3\times10^6[/tex]
On comparing to [tex]a\times 10^{b}[/tex] , we get a = 3 and b=6
So, the approximate number of particles of skin a human can shed in five hours can be written in the form a times 10^b, where a is 3 and b is 6 .
Answer:
6
Step-by-step explanation:
First, write the approximate number of particles of skin a human can shed in five hours in scientific notation. This number is three million which can be written in the form a × 10b, where a is 3 and b is 6.

Simon went to high school from 2012 to 2017. He was born when his father was 25. Simon’s parents met while they were in high school together. Part A Choose the compound inequality that describes the year x when Simon’s parents met.
Answers
Answer:
Simon started High school in the year 2012.
One usually starts highs school when is 14 years old.
So we can assume that Simon was born 14 years before 2012:
2012 - 14 = 1998
Now, Simon's parents may have met in the beginning of 1998, and Simon was born by the end of 1998. But in that case, Simon would be 13 at the beginning of school, instead of 14.
Then Simon's parents should have met before 1998.
Then the inequality that we have:
x < 1998.
And Simon was born when his father was 25 years old.
Then in 1998, Simon's father was 25 years old.
Meaning that he was born around:
1998 - 25 = 1973.
This means that Simon's parents met in-between the years 1973 and 1998.
1973 < x < 1998

Find the values of x and y. 3x - 5 5y - 4 y + 12
Answers
The values of x and y in the equilateral and Isosceles triangles are 7 and 4 respectively.
What is an equilateral triangle?An equilateral triangle is a triangle that has all its sides equal to each other.
Therefore,
3x - 5 = 5y - 4 (equilateral triangle)
3x - 5y = 1
Therefore,
y + 12 = 3x - 5 (Isosceles triangle)
y - 3x = - 17
Hence,
3x - 5y = 1
- 3x + y = - 17
-4y = -16
y = -16 / -4
y = 4
Therefore,
3x = 1 + 5(4)
3x = 21
x = 21 / 3
x = 7

The straight line 4x+5y-20 = 0 cuts the X-intercept, Y-intercept and hence find area of traingleAOB
Answers
Answer:
The area of the triangle AOB is 10
Step-by-step explanation:
The line 4x+5y-20=0 forms a triangle AOB as shown in the figure below. The points A and B are the y-intercept and x-intercept respectively, and the point O is the origin.
To find the intercepts, we set the other variable to zero and solve the resulting equation.
Set x=0, the y-intercept is found as follows:
4(0)+5y-20=0
5y=20
y=20/5=4
The y-intercept is y=4
Set y=0, the x-intercept is now found:
4x+5(0)-20=0
4x=20
Solve:
x=20/4=5
The x-intercept is x=5
Now, knowing the base b and the height of the triangle h are 5 and 4 respectively, the area of the triangle is:
[tex]\displaystyle A=\frac{bh}{2}[/tex]
[tex]\displaystyle A=\frac{5\cdot 4}{2}=10[/tex]
The area of the triangle AOB is 10

PLEASE BE QUIIICCCKKK

Answer:
I think its C or A
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
A function can never have a 'x' with two values.
If you say f(x) = a, then there is only one number 'a' which satisfy. If however, you say f(x) = a & f(x) = b, then it's not a function, since there are two values of f(x).
Following this,
A: x = 3 has two f(x) = 2 & 1, so it's not a function
Similarly you can check for all.
There is only one table which x has a unique value.
Correct B
Note that, f(x) = a & f(x) = b, doesnt represent a function. If it is, then a = b is must.
Also, a function is possible only when it satisfies this. But
f(x) = a, f(y) = a, f(z) = a is possible.

Animal riddle
In reply to an inquiry about the animals on his farm, the farmer says: “I only ever keep sheep, goats, and horses. In fact, at the moment they are all sheep bar three, all goats bar four, and all horses bar five.” How many does he have of each animal?
Answers
Here’s the answer & how to find it! So let us suppose,
X : the no. of sheep he owns
Y : the no. of goats he owns
Z : the no. of horses he owns
This means,
X + Y + Z = Total no. of animals he owns
He says that “They are all sheep bar three.” Which means, the no. of animals other than sheep is 3, i.e.
Y + Z = 3
Similarly,
X + Z = 4 and X + Y = 5
On adding all the three equations, we get
2 ( X + Y + Z ) = 12
This implies,
X + Y + Z = 6
This means that the farmers has a total of 6 animals. And on further solving the equations we find that the he has 3 sheep, 2 goats and a horse.
