Nico and Lorena used different methods to determine the product of three fractions.
Nico’s Method
Lorena’s Method
(2) (one-sixth) (Negative four-fifths) = (StartFraction 2 over 1 EndFraction) (one-sixth) (negative four-fifths) = StartFraction (2) (1) (negative 4) over (1) (6) (5) EndFraction = Negative StartFraction 8 over 30 EndFraction = Negative StartFraction 4 over 15 EndFraction
(2) (one-sixth) (Negative four-fifths) = (StartFraction 2 over 1 EndFraction) (one-sixth) (negative four-fifths) = StartFraction (2) (1) (negative 4) over (1) (6) (5) EndFraction = Negative StartFraction 8 over Negative 30 EndFraction = StartFraction 4 over 15 EndFraction
Whose solution is correct and why?
Nico is correct because he knew that Negative four-fifths = StartFraction negative 4 over negative 5 EndFraction.
Nico is correct because he knew that Negative four-fifths = StartFraction negative 4 over 5 EndFraction.
Lorena is correct because she knew that Negative four-fifths = StartFraction negative 4 over 5 EndFraction
Lorena is correct because she knew that Negative four-fifths = StartFraction negative 4 over negative 5 EndFraction
Answer:
Nico is correct because he knew that -4/5 is not equal to -4/-5.

A group of students is timed while sprinting 100 meters. Each student’s speed can be found by dividing 100 m by their time. Is each statement true or false?
Select the correct choice for each statement then explain your reasoning.
1. Speed is a function of time.
2. Time is a function of distance.
3. Speed is a function of number of students racing.
4. Time is a function of speed.
Answer:
The true statements are (a) and (d)
Step-by-step explanation:
(a). Speed is a function of time : As seen from equation (1) Speed of the students varies according to the value of time. So, This a true statement.
(b). Time is a function of distance : Distance is not varying in the equation (1), it is fixed to be 100. So, time is not a function of distance because here the distance is made constant. So, This is false statement.
(c). Speed is a function of number of students racing : Speed is not depending on the number of students racing so sped is independent of the number of the students racing. Therefore, Speed is not a function of number of students racing. This is False statement.
(d). Time is a function of speed : As seen from equation (1) Time of the students varies according to the value of their speed. So, This a true statement.
The true statements are (a) and (d).

When the y-intercept is positive, where does the line cross the y-axis on the graph? When it is negative?
Answer:
1. 0,0
2. negative 1
Step-by-step explanation:
It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

Answer:
y^8 goes to the last one
y^6 goes to the third one
y^5 goes to the second one
then the last one go to the first one
Answer:
(y)^-2 = 1/y^2, (y^3)^2 = y^6, y^8 -:- y^3 = y^5, and y^4 x y^4 = y^8
Step-by-step explanation:
When you divide y^8 -:- y^3, you subtract ^8-^3 = ^5, so its y^8 -:- y^3 = y^5
When you multiply y^4 x y^4, you add ^4 + ^4 = ^8, so it is y^4 x y^4 = y^8
When you multiply (y^3)^2, you multiply ^3 x ^2 = ^6, so its (y^3)^2 = y^6
And when you have a negative exponent,(^-2) you have to make it positive, so it would be y^-2 = 1/y^2

Answer:
The first option is correct, 12/30 and 25/30
Step-by-step explanation:
To get common denominators, you need to find the GFC (greatest common factor) of 5 and 6, which is 30. Then you would need to make the fractions equal the same as the original fractions, by multiplying.
2/5 = ?/30 <- you can see that 30 is 6 times more than 5. so this means you multiply 2 by 6 to get 12. 12/30
5/6 = ?/30 <- you can see that 30 is 5 times more than 6. so this means you multiply 5 by 5 to get 25. 25/30

sean earned $31,000 last year. if the first $25,000 is taxed at 9% and income above is taxed at 15%, how much does sean owe in tax?
$3,150
$3,550
$4,100
$4,320
The amount for Sean owe in tax will be $3,150.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
Sean earned $31,000 last year.
In the first $25,000 is taxed at 9% and income above is taxed at 15%.
Now,
Since, In the first $25,000 is taxed at 9%.
Hence, The amount of tax = 9% of $25,000
= 9/100 × $25,000
= $2,250
And, Income above is taxed at 15%.
Hence, The above income = $31,000 - $25,000
= $6,000
So, The tax for above income = 15% of $6,000
= 15/100 × 6,000
= $900
Thus, The total tax = $2,250 + $900
= $3,150
