Staples sells boxes of pens ($18) and rubber bands ($6). Leona ordered a total of 20 cartons for $300. How many boxes of each did Leona order?
-Let be "p" the number of boxes of pens that Leona ordered and "r" the number of rubber bands she ordered.
According to the information given in the exercise:
- The cost of 1 box of pens is $18 and the cost of 1 box of rubber bands is $6.
- Leona ordered 20 cartons.
- The total cost was $300.
Using this information you can set up the following System of Equations:
\(\begin{cases}18p+6r=300 \\ p+r=20\end{cases}\)In order to solve it, you can apply the Elimination Method:
1. Multiply the second equation by -6.
2. Add the equations.
3. Solve for "p".
Then:
\(\begin{gathered} \begin{cases}18p+6r=300 \\ -6p-6r=-120\end{cases} \\ ------------- \\ 12p+0=180 \\ \\ p=\frac{180}{12} \\ \\ p=15 \end{gathered}\)4. Substitute the value of "p" into the second original equation.
5. Solve for "r".
Then:
\(\begin{gathered} p+r=20 \\ (15)+r=20 \\ r=20-15 \\ r=5 \end{gathered}\)Therefore, the answer is: Leona ordered 15 boxes of pens and 5 boxes of rubber bands.

a furlong is a distance of 180 yards. a fortnight is a time period of two weeks. a race horse is running at a speed of 7 yards per second. what is his speed in furlongs per fortnight?
The race horse's speed is approximately 256 furlongs per fortnight.
To determine the race horse's speed in furlongs per fortnight, we need to convert both the distance and time units to their respective values.
1 furlong is equal to 180 yards, so the horse's speed in yards per second (7 yards/second) can be converted to furlongs per second:
Speed in furlongs per second = (7 yards/second) / (180 yards/furlong) = 7/180 furlongs/second
Next, we need to convert the time from seconds to fortnights. Since a fortnight is a time period of two weeks, and there are 7 days in a week, a fortnight consists of 14 days:
Time in seconds per fortnight = (14 days/fortnight) * (24 hours/day) * (60 minutes/hour) * (60 seconds/minute) = 1,209,600 seconds/fortnight
Finally, we can calculate the horse's speed in furlongs per fortnight by multiplying the speed in furlongs per second by the time in seconds per fortnight:
Speed in furlongs per fortnight = (7/180 furlongs/second) * (1,209,600 seconds/fortnight) = 46,080/180 furlongs/fortnight ≈ 256 furlongs/fortnight
The race horse's speed is approximately 256 furlongs per fortnight.

Hey guys ( or gals ) I have no idea what to do please help me.
Answer:
Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.
You would have to find a GCF (greatest common factor) and multiply it out of the radical.
ex.
\(\sqrt{6}\) = 2 x 2 x 2
when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2
2\(\sqrt{2\\}\)
so \(\sqrt{6}\) would be closest to the positive 2 on the number line and 2 notches.
\(\sqrt{11}\)
is an irrational number, so it might fall into 3.3 if turned into a decimal.
Step-by-step explanation:
x and y each take on values 0 and 1 only and are independent. their marginal probability distributions are:
f(x) =1/3, if X = 0 and f(x) = 2/3 if X = 1 f(y) =1/4, if Y = 0 and f(y) = 3/4 if Y = 1 Determine corresponding joint probability distribution.
The corresponding joint probability distribution is:
X\Y 0 1
0 1/12 1/4
1 1/6 1/2
Since X and Y are independent, the joint probability distribution is simply the product of their marginal probability distributions:
f(x,y) = f(x) × f(y)
Therefore, we have:
f(0,0) = f(0) ×f(0) = (1/3) × (1/4) = 1/12
f(0,1) = f(0) × f(1) = (1/3) × (3/4) = 1/4
f(1,0) = f(1) × f(0) = (2/3) × (1/4) = 1/6
f(1,1) = f(1) ×f(1) = (2/3) × (3/4) = 1/2

Addison's Diner offers its clients a choice of regular and diet soda. Last night, the diner served 21 regular sodas and 29 diet sodas. What percentage of the sodas served were regular?
From the given information provided, out of total sodas served, 42% of the sodas served were regular.
To find the percentage of sodas served that were regular, we need to calculate the ratio of the number of regular sodas to the total number of sodas served, and then express this ratio as a percentage.
The total number of sodas served is the sum of regular and diet sodas:
Total sodas served = 21 + 29 = 50
The number of regular sodas served is 21.
To find the percentage of sodas served that were regular, we can use the following formula:
Percentage of regular sodas = (Number of regular sodas / Total number of sodas served) x 100%
Substituting the values, we get:
Percentage of regular sodas = (21 / 50) x 100%
Percentage of regular sodas = 42%

The another equivalent expression of total liquid is (x+2)/4.
Expressions that perform similarly but differ in appearance are said to be equivalent expressions. When the same value for the variable is entered, two algebraic expressions that are equivalent will have the same result.
x quarts liquid in the container 3/4 part of liquid is removed
Then remaining liquid in container = X - \(\frac{3}{4}X\)
Then remaining liquid in container = x/4quarts
Another 1/2 quart is poured into container
Then total liquid = \(X-\frac{3}{4}X+\frac{1}{2}\) quarts

A circular sheet of paper with radius of $6$ cm is cut into three congruent sectors. What is the height of the cone in centimeters that can be created by rolling one of the sections until the edges meet
According to the question The height of the cone that can be created by rolling one of the congruent sectors is approximately 6.32 cm.
To find the height of the cone that can be created by rolling one of the congruent sectors of the circular sheet, we need to calculate the circumference of the base of the cone.
The circumference of the base is equal to the length of the sector's arc, which can be calculated using the formula:
\(\[ \text{Arc Length} = \left(\frac{\text{Central Angle}}{360^\circ}\right) \times \text{Circumference of the Circle} \]\)
Since the sector is one-third of the circle, the central angle of the sector is \(\( 120^\circ \) (\( \frac{360^\circ}{3} \)).\)
The circumference of the circle is given by the formula:
\(\[ \text{Circumference} = 2 \pi \times \text{radius} \]\)
Substituting the values, we have:
\(\[ \text{Circumference} = 2 \pi \times 6 \, \text{cm} = 12\pi \, \text{cm} \]\)
Now, we can calculate the arc length:
\(\[ \text{Arc Length} = \left(\frac{120^\circ}{360^\circ}\right) \times 12\pi \, \text{cm} = 4\pi \, \text{cm} \]\)
When the sector is rolled to form a cone, the arc length becomes the circumference of the base of the cone.
The circumference of the base of the cone is also equal to \(\( 2\pi \times \text{radius of the cone} \).\)
Therefore, we can equate the two circumferences and solve for the radius of the cone:
\(\[ 2\pi \times \text{radius of the cone} = 4\pi \, \text{cm} \]\)
Dividing both sides by \(\( 2\pi \)\), we find:
\(\[ \text{Radius of the cone} = 2 \, \text{cm} \]\)
Now, the height of the cone can be calculated using the Pythagorean theorem:
\(\[ \text{height}^2 = (\text{radius of the cone})^2 + (\text{radius of the base})^2 \]\)
\(\[ \text{height}^2 = 2^2 + 6^2 = 4 + 36 = 40 \]\)
Taking the square root of both sides, we get:
\(\[ \text{height} \approx \sqrt{40} \approx 6.32 \, \text{cm} \]\)
Therefore, the height of the cone that can be created by rolling one of the congruent sectors is approximately 6.32 cm.

i = 20
R = -2
=====================================================
Explanation:
\(S_0 = 20\) is the initial term because your teacher mentioned \(A_0 = I\) as the initial term.
Then R = -2 is the common difference because we subtract 2 from each term to get the next term. In other words, we add -2 to each term to get the next term.
Here is the scratch work for computing terms S1 through S4.
\(\begin{array}{|l|l|}\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{1} = S_{1-1} - 2 & S_{2} = S_{2-1} - 2\\S_{1} = S_{0} - 2 & S_{2} = S_{1} - 2\\S_{1} = 20 - 2 & S_{2} = 18 - 2\\S_{1} = 18 & S_{2} = 16\\\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{3} = S_{3-1} - 2 & S_{4} = S_{4-1} - 2\\S_{3} = S_{2} - 2 & S_{4} = S_{3} - 2\\S_{3} = 16 - 2 & S_{4} = 14 - 2\\S_{3} = 14 & S_{4} = 12\\\cline{1-2}\end{array}\)
Then here is S5 though S8
\(\begin{array}{|l|l|}\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{5} = S_{5-1} - 2 & S_{6} = S_{6-1} - 2\\S_{5} = S_{4} - 2 & S_{6} = S_{5} - 2\\S_{5} = 12 - 2 & S_{6} = 10 - 2\\S_{5} = 10 & S_{6} = 8\\\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{7} = S_{7-1} - 2 & S_{8} = S_{8-1} - 2\\S_{7} = S_{6} - 2 & S_{8} = S_{7} - 2\\S_{7} = 8 - 2 & S_{8} = 6 - 2\\S_{7} = 6 & S_{8} = 4\\\cline{1-2}\end{array}\)
And finally we arrive at S9.
\(S_{n} = S_{n-1} - 2\\\\S_{9} = S_{9-1} - 2\\\\S_{9} = S_{8} - 2\\\\S_{9} = 4 - 2\\\\S_{9} = 2\\\\\)
--------------------
Because we have an arithmetic sequence, there is a shortcut.
\(a_n\) represents the nth term
S9 refers to the 10th term because we started at index 0. So we plug n = 10 into the arithmetic sequence formula below.
\(a_n = a_1 + d(n-1)\\\\a_n = 20 + (-2)(n-1)\\\\a_n = 20 - 2(n-1)\\\\a_{10} = 20 - 2(10-1)\\\\a_{10} = 20 - 2(9)\\\\a_{10} = 20 - 18\\\\a_{10} = 2\\\\\)
In other words, we start with 20 and subtract off 9 copies of 2 to arrive at 20-2*9 = 20-18 = 2, which helps see a faster way why \(S_9 = 2\)

The division of the fraction 6/7 by 9/15 gives the result 4/3.
To simplify the division of 6/7 divided by 9/14, multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of a fraction is obtained by swapping the numerator and the denominator.
So, the reciprocal of 9/14 is 14/9.

Given \( f(x)=\log _{3}(9 x) \) and \( g(x)=3^{x} \). Find and simplify \( (f o g)(x) \) \( 2 x \) \( 27^{x} \) \( 2+x \) None of these.
The simplified expression for (f ∘ g)(x) is 2 + x (option d).
To find and simplify (f ∘ g)(x), we need to substitute the expression for g(x) into f(x) and simplify.
Given:
f(x) = log₃(9x)
g(x) = \(3^x\)
Substituting g(x) into f(x):
(f ∘ g)(x) = f(g(x)) = log₃\((9 * 3^x)\)
Now, we simplify the expression:
log₃\((9 * 3^x)\) = log₃(9) + log₃\((3^x)\)
Since logₓ(a * b) = logₓ(a) + logₓ(b), we have:
log₃(9) + log₃\((3^x)\) = log₃\((3^2)\) + x
Using the property logₓ\((x^a)\) = a * logₓ(x), we get:
log₃\((3^2)\) + x = 2 * log₃(3) + x
Since logₓ\((x^a)\) = a, where x is the base, we have:
2 * log₃(3) + x = 2 + x
Therefore, (f ∘ g)(x) simplifies to:
(f ∘ g)(x) = 2 + x
So, the correct answer is (d) 2 + x.
