Answer and explanation :
Hannah said that [tex]\frac{1}{8}[/tex] is not on the number line but she is wrong because [tex]\frac{1}{8}[/tex] can be represented on the number line
When we convert the fraction [tex]\frac{1}{8}[/tex] into decimal then it is equal to 0.125
And 0.125 lies between 0 and 1
If we divide one unit on number line into 10 parts then 0.125 lie between 0.1 and 0.2
And we know that any real number can be represented on number line as 0.125 is a real number so it can be represented on the number line
Answer:
This number line represents all number. Although 1

which is the product of 7/9 and 6?
Answer:
14/3
Step-by-step explanation:
7 x 6
9 1
7x6=42
9X1=9
42/9 or 14/3
The product of 7/9 and 6 is 14/3.
Explanation:To find the product of 7/9 and 6, multiply the numerator (7) by the number (6) and keep the denominator (9) the same.
The calculation is as follows:
(7/9) * 6
= (7 * 6)/9
= 42/9
To simplify the fraction, divide both the numerator and the denominator by their greatest common factor, which is 3.
The simplified answer is: 14/3
Solve the proportional equation below:
10/2=a/a-9
a. 11.25
b. 7
c. 2
d. 1.125
To solve the given proportional equation, it simplifies to 5 = a/(a-9), leading to 4a = 45 after simplification and solving, with the solution being a = 11.25.
Explanation:To solve the proportional equation 10/2 = a/(a-9), we first simplify and then solve for a. The equation simplifies to 5 = a/(a-9). By cross-multiplication, we get 5(a - 9) = a, which simplifies to 5a - 45 = a. Bringing all terms to one side gives 4a = 45, and dividing both sides by 4 gives a = 11.25. Therefore, the correct answer is a. 11.25.
Explain why dividing by a fraction results in the same answer as multiplying by its reciprocal.
Answer:
lets consider an example like
20 divided by 2/4 so we can rewrite as
2/4* x =20
so , 2* x =20*4
2* x =80
x=80/2
x=40
similarly,we can write the fraction as (20*4/2)-we can see that reciprocal of the fraction 2/4 is 4/2
x=20*4/2=80/2=40
so, we can say that dividing by a fraction results in the same answer as multiplying by its reciprocal.
a scientist has a bottle that is 5/8 full of solution. he used 2/5 of the solution in the bottle for an experiment. how much of a full bottle of solution does he use?
Final answer:
The scientist used 9/40 of a full bottle of solution.
Explanation:
To find out how much of a full bottle of solution the scientist used, we first need to calculate the amount that is left in the bottle. The bottle is currently 5/8 full, and the scientist used 2/5 of the solution. To calculate the amount left, we subtract the amount used from the initial amount:
Amount Left = Initial Amount - Amount Used
To subtract fractions, we need a common denominator. The common denominator for 8 and 5 is 40:
Amount Left = 5/8 - 2/5
To subtract the fractions, we need to have the same denominator, which is 40:
Amount Left = (5/8) * (5/5) - (2/5) * (8/8)
Amount Left = 25/40 - 16/40
Amount Left = 9/40
Therefore, the scientist used 9/40 of a full bottle of solution.

On the calculator, click on the graph of y = 3x and trace to view the coordinates. When the x-coordinate is 4, what is the y-coordinate?
the y-coordinate corresponding to x=4 is 12.
the equation y=3x represents a linear function. A linear function is a type of mathematical relationship where the graph of the function forms a straight line.
The equation y=3x is in slope-intercept form, where y represents the dependent variable (usually plotted on the vertical axis),
x represents the independent variable (usually plotted on the horizontal axis), and 3 represents the slope of the line.
To find the y-coordinate when the x-coordinate is 4 in the equation y=3x, we need to substitute x=4 into the equation and solve for y.
Substituting x=4 into the equation y=3x,
we get: y=3×4=12
So, when x=4, y=12.
Therefore, the y-coordinate corresponding to x=4 is 12.
This means that the point on the graph of y=3x where the x-coordinate is 4 has a y-coordinate of 12.

At the zoo, the Spencer family bought 3 adult tickets and 2 children's tickets for $23.50. The Yang family bought 2 adult tickets and 4 children's tickets for $25. How much would the Diaz family spend if they bought 3 adults tickets and 1 children's ticket?
Diaz family spend $ 20 if they bought 3 adults tickets and 1 children's ticket
Solution:
Let "a" be the cost of each adult ticket
Let "c" be the cost of each student ticket
The Spencer family bought 3 adult tickets and 2 children's tickets for $23.50
Therefore, we frame a equation as:
[tex]3 \times a + 2 \times c = 23.50[/tex]
3a + 2c = 23.50 --------- eqn 1
The Yang family bought 2 adult tickets and 4 children's tickets for $25
Therefore, we frame a equation as:
[tex]2 \times a + 4 \times c = 25[/tex]
2a + 4c = 25 ----------- eqn 2
Let us solve eqn 1 and eqn 2
Multiply eqn 1 by 2
6a + 4c = 47 ---------- eqn 3
Subtract eqn 2 from eqn 3
6a + 4c = 47
2a + 4c = 25
( - ) --------------
4a = 47 - 25
4a = 22
Divide both sides of equation by 4
a = 5.5
Substitute a = 5.5 in eqn 1
3(5.5) + 2c = 23.50
16.5 + 2c = 23.50
2c = 23.50 - 16.5
2c = 7
Divide both sides of equation by 2
c = 3.5
Thus, cost of each adult ticket = $ 5.5
Cost of each student ticket = $ 3.5
How much would the Diaz family spend if they bought 3 adults tickets and 1 children's ticket?
Total cost = 3a + 1c
Total cost = 3(5.5) + 1(3.5) = 16.5 + 3.5
Total cost = 20
Thus Diaz family spend $ 20
Final answer:
The Diaz family would spend $20 for 3 adult tickets and 1 children's ticket at the zoo after solving the system of linear equations given by the Spencer and Yang families' purchases.
Explanation:
Let A be the price of an adult ticket and C be the price of a children's ticket. We are given:
3A + 2C = $23.50 (Spencer family)
2A + 4C = $25 (Yang family)
To solve this system, we can multiply the first equation by 2 and the second equation by 3:
6A + 4C = $47 (Spencer family doubled)
6A + 12C = $75 (Yang family tripled)
Subtracting the first equation from the second gives us:
8C = $28
Dividing both sides by 8 yields:
C = $3.50
Now that we know the price of a children's ticket, we can substitute this value back into one of the original equations to find the price of an adult ticket.
3A + 2(3.50) = $23.50
3A + $7 = $23.50
3A = $16.50
A = $5.50
With the price of both ticket types known, we can now calculate the cost for the Diaz family:
3A + 1C = 3($5.50) + 1($3.50)
3A + 1C = $16.50 + $3.50
3A + 1C = $20
Therefore, the Diaz family would spend $20 if they bought 3 adult tickets and 1 children's ticket.

-3t-8+7t =34 +9t -2
Solve for t
Please give an exposition
Answer:
t = -8
Step-by-step explanation:
combine like terms, so -3t + 7t = 4t and 34 - 2 = 32
so 4t - 8 = 32 + 9t
then subtract 4t from both sides and subtract 32 from both sides. You will get: -40 = 5t.
Then divide both sides by 5 so you will get -8 = t
Answer: t= -8
Step-by-step explanation:

The ratio of faculty members to students at a college is 1:15. If there are 675 students, then how many faculty members are there?
Answer:
The number of faculty member is 45.
Step-by-step explanation:
Ratio of faculty members to students = 1 : 15
Number of students = 675
Total = Number students + faculty members
Let the total be t
Let the faculty member be f
Representing the ratio, we have:
[tex]\frac{15}{16} * t = 675\\\frac{15t}{16} = 675\\15t = 16 * 675\\15t = 10800\\\frac{15t}{15} =\frac{10800}{15} \\t = 720[/tex]
Therefore, the total number of both the students and faculty member is 720. To get the number of faculty member:
Total = Number students + faculty members
[tex]720 = 675 + f\\f = 720 - 675\\f = 45[/tex]
The number of faculty member is 45.

You have decided to purchase a new Toyota 4Runner for $25,635. You have promised your daughter that the SUV will be hers when the car is worth $10,000. According to your car dealer, the SUV will depreciate in value approximately $3000 per year.
a) Write a linear equation in which y represents the total value of the car and x represents the age of the car,
The linear equation representing the value of the car as it depreciates over time is y = -3,000x + 25,635, where y is the value of the car and x is the age of the car in years.
To write a linear equation that describes the depreciation of the SUV over time, we define two variables: y represents the total value of the car at any time x, where x represents the age of the car in years.
The car is purchased for $25,635 and depreciates at a rate of $3,000 per year, which means that the value of the car decreases by a constant amount each year. We can write this situation as a linear function:
Linear Depreciation Equation:
y = -3,000x + 25,635
Here, the y-intercept is $25,635 (the value of the car at the time of purchase when x is zero), and the slope is -$3,000 (the rate at which the value of the car decreases per year).
Together, teammates Pedro and Ricky got 2693 base hits last season. Pedro had 283 more
hits than Ricky. How many hits did each player have?
Answer: Pedro= 1205. Ricky= 1488
Step-by-step explanation:
It is found that Ricky hits 1202 base and Pedro hits = 1485 base
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Given that
Pedro + Ricky = 2693 hits
Let Ricky hits = x
So, the Pedro hits will be = x + 283
( x + 283 ) + x = 2693
2 x + 283 = 2693
2 x = 2693 - 283
2 x = 2404
x = 1202
So, the Ricky hits 1202 base
Thus Pedro hits (1202 + 283) = 1485 base
