Answer:
12 over 60
Step-by-step explanation:
The experimental probability of landing on a number less than 2 can be calculated by counting the number of times the outcome was 1, which is 12, and dividing it by the total number of trials, which is 60.
So, the experimental probability is 12/60 = 1/5 = 12 over 60.
Answer: 12 over 60

The equation of the horizontal asymptote of f(x) is given as follows:
x = 5/4.
How to obtain the horizontal asymptote of f(x)?The rational function f(x) in the context of this problem is defined as follows:
f(x) = (-4x² + 54x - 47)/(4x - 5).
The horizontal asymptote of a function happens at a value of x which is outside the function's domain.
For a rational function, the denominator cannot be zero, hence the value of x that represents the horizontal asymptote of f(x) is obtained as follows:
4x - 5 = 0
4x = 5
x = 5/4.

With only a part-time job and the need for a
professional wardrobe, Rachel quickly
maxed out her credit card the summer after
graduation.
With her first full-time paycheck in August,
she vowed to pay $250 each month toward
paying down her $8,281 outstanding
balance and not to use the card.
The card has an annual interest rate of 16%.
How long will it take Rachel to pay for her
wardrobe? Should she shop for a new card?
Why or why not?
Regarding shopping for a new card, it would depend on the terms and conditions of the new card, including the annual interest rate and any fees. Rachel should compare the options available and weigh the benefits and drawbacks of each before making a decision.
How to solve the problem?The length of time it will take Rachel to pay off her credit card balance can be calculated by dividing the outstanding balance by the monthly payment amount and then adding the number of months needed to pay off the balance.
Balance = $8,281
Monthly payment = $250
Annual interest rate = 16%
To calculate the length of time it will take to pay off the balance, we would first need to calculate the monthly interest rate, which can be done by dividing the annual interest rate by 12:
Monthly interest rate = 16% / 12 = 1.33%
Next, we can calculate the monthly payment amount, including the interest:
Monthly payment amount = $250 + ($8,281 * 1.33%)
By continually subtracting the monthly payment amount from the balance and adding the monthly interest, we can determine the length of time it will take to pay off the balance.
Regarding shopping for a new card, it would depend on the terms and conditions of the new card, including the annual interest rate and any fees. Rachel should compare the options available and weigh the benefits and drawbacks of each before making a decision.

Select the GCF of these numbers. 2^5 · 5· 11 and 2^3· 5^2 · 7
Answer:
To find the GCF of 2^5·5·11 and 2^3·5^2·7, we first prime factorize each number:
2^5·5·11 = 2^5 x 5 x 11
2^3·5^2·7 = 2^3 x 5^2 x 7
Next, we look for the highest power of each prime factor that they both have in common:
2^3 is the highest power of 2 that both numbers have.
5^2 is the highest power of 5 that both numbers have.
So, the GCF of 2^5·5·11 and 2^3·5^2·7 is 2^3 x 5^2 = 180.

RHL = LHL = F(x)
Limit exist and continuous
Given that,
F(x) = [x² - 49]/[x² + 6x -7][x² + 14x + 49]
To check whether it is continuous at x = 3

The area of a rectangle is 50ft , and the length of the rectangle is 5 ft less than three times the width. Find the dimensions of the rectangle.
We know from the problem that l = 3w - 5. We also know the formula for area is A = w * l. Therefore, the area of the rectangle is A = w * (3w - 5). We can then set this equation equal to 50 as the question states and solve for w.
[tex]50 = w * (3w-5)[/tex]
Expand the multiplication
[tex]50 = 3w^{2}- 5w[/tex]
Subtract 50 from both sides.
[tex]0 = 3w^{2} - 5w - 50[/tex]
We now have a quadratic equation and can solve it using the quadratic formula to find w. We find that the solutions to the equation are 5 and -3.3. We know that the width can't be negative, so the width must be 5.
Finally, we can plug this solution into the length formula we found earlier to solve for length.
[tex]l = 3w - 5[/tex]
Plug in the solution to w.
[tex]l = 3(5) - 5[/tex]
Multiply 3 and 5.

If Jane took 30 min to drive her boat upstream to water-ski at her favorite spot. her boat speed in still water is;3 km/h.
How to find the speed?Let's x represent the Jane's boat speed in still water
Upstream, her speed was x - 2 km/h.
Downstream, her speed was x + 2 km/h.
Let's d represent the distance between the start and end point
Let the time it takes to cover d at a speed of x - 2 km/h= 30 min.
Let the time it takes to cover d at a speed of x + 2 km/h= 10 min.
So we have:
d / (x - 2) = 30 min and
d / (x + 2) = 10 min.
Multiplying both sides of each equation
d * x - 2d = 30 * (x - 2)
d * x + 2d = 10 * (x + 2).
Adding the two equations and solve for x
2d * x = 40 * x + 20
20 * x = 40 * x + 20
20 * x = 60 * x

In trapezoid ABCD, line AC is a diagonal and angle ABC is congruent to angle ACD. Find AC if the lengths of the bases line BC and line AD are 12m and 27m, respectively
Since ΔABC and ΔACD are similar triangles, therefore the length of AC is 18 m.
What are Similar Triangles?Similar triangles are triangles with corresponding sides that have the same ratio.
Thus:
AD is parallel to BC (bases of a trapezoid are parallel)
Therefore:
∠ACB = ∠CAD (alternate interior angles)
This implies that, ΔABC ~ ΔACD by AA similarity theorem.
Thus:
AC/DA = CB/AC
Substitute
AC² = 12 × 27
AC = √324
AC = 18 m
Therefore, since ΔABC and ΔACD are similar triangles, therefore the length of AC is 18 m.
