Answer:
A. 4.5%; November 25
Step-by-step explanation:
4.5/10 EOM is a type of payment term you will see on an invoice. The 4.5 stands for discount percentage and the 10 is a number of days. 4.5/10 means the payment on the invoice is due in 10 days. EOM stands for end of the month. So if the amount is paid within 10 days, the customer gets a discount of 4.5%. Which means the last day to pay in full is November 25. After that there is no discount.

What is the solution to the equation below?
Please show work.
Answer:
x = -9
Step-by-step explanation:
Multiply both sides by √(x - 6) to eliminate the fraction:
√(3x) = 3√(x - 6)
Now square both sides:
3x = 9(x - 6), or 3x = 9x - 54.
Combining the x terms results in -6x = -54, and thus x = 9.
Answer:
The correct answer is option D. x = 9
Step-by-step explanation:
From the attached question we get an expression,
√3x/√(x - 6) = 3
To find the solution of given expression
√3x/√(x - 6) = 3
Squaring both side we get,
3x/(x - 6) = 9
3x = 9 * (x - 6)
3x = 9x - 54
9x - 3x = 54
6x = 54
x = 54/6 = 9
Therefore the correct option is D. x = 9

Which explanation best describes how to solve this problem? Marcia covered her kitchen floor with twice as much tile as her bathroom floor. She tiled 15 square feet of her bathroom floor. She also tiled a 9-square-foot area by her front door. How many square feet of her house did Marcia tile altogether?
Answer:
54 ft^2
Step-by-step explanation:
Bathroom area is 15 ft^2
The kitchen is twice the bathroom
2*15 = 30 ft^2
Kitchen: 30 ft^2
Front door: 9ft^2
The total is all the areas added together
Total = bathroom + kitchen + front door
= 15 ft^2 + 30 ft^2 + 9 ft^2
= 54 ft^2

Which choice is equivalent to the fraction below when x is greater than or equal to 2?
Answer:
D. 2(√{x} + √{x - 2})
Step-by-step explanation:
As hinted in the question, we have to simplify the denominator.
To understand it easier, let's imagine we have x - y in the denominator. If we multiply it with x + y we'll get x² - y², right? Check the next line:
(x - y) (x + y) = x² + xy -xy - y² = x² - y²
If we have the square of those nasty square roots, it will be much simpler to deal with. So, let's multiply the initial fraction using x+y, but with the real values:
[tex]\frac{4}{\sqrt{x} - \sqrt{x - 2} } * \frac{\sqrt{x} + \sqrt{x - 2}}{\sqrt{x} - \sqrt{x - 2}} = \frac{4(\sqrt{x} + \sqrt{x - 2})}{(\sqrt{x} )^{2} - (\sqrt{x - 2} )^{2} }[/tex]
Then we simplify:
[tex]\frac{4(\sqrt{x} + \sqrt{x - 2})}{(\sqrt{x} )^{2} - (\sqrt{x - 2} )^{2} } = \frac{4(\sqrt{x} + \sqrt{x - 2})}{(x) - (x - 2) } = \frac{4(\sqrt{x} + \sqrt{x - 2})}{ 2 } = 2(\sqrt{x} + \sqrt{x - 2})[/tex]

Fred's dog groomer charges $25 to give his dog a haircut. The groomer is increasing the price for a haircut by 35%. What will Fred pay the groomer the next time his dog has a haircut?
Answer:
33.75
Step-by-step explanation:
Step 1- Find the decimal form of 35%
Step 2- When you find that multiply that by 25
Step 3- When you find the answer to step 2 add that to 25
That is your answer
Final answer:
The price that Fred will pay the groomer the next time when his dog has a haircut is $33.75.
Explanation:
The question asks us to calculate the new price Fred will pay for his dog's haircut after the groomer increases the price by 35%. To find the new price, we'll use the formula for calculating percentage increase, which is: New Price = Original Price + (Original Price * Percentage Increase).
First, convert the percentage increase to a decimal by dividing it by 100, so 35% becomes 0.35. Then, multiply the original price of $25 by 0.35 to find the amount of the increase, which is $8.75.Finally, add the increase to the original price to find the new price, which is $25 + $8.75 = $33.75. So, Fred will pay $33.75 the next time his dog has a haircut.
Mr. McGregor has discovered that a large dog can destroy his entire garden in 2 hours and that a small boy can do the same job in 1 hour. How long would it take the large dog and the small boy working together to destroy Mr McGregor's garden?
The large dog and small boy working together will take 2/3 hour to destroy Mr McGregor's garden.
Explanation:To solve this problem, we can add the rates at which the large dog and the small boy work together:
Large dog's rate = 1 garden / 2 hours = 1/2 garden per hour
Small boy's rate = 1 garden / 1 hour = 1 garden per hour
Combined rate = 1/2 garden per hour + 1 garden per hour = 3/2 gardens per hour
Now, we can use the combined rate to find the time it would take for the large dog and the small boy to destroy Mr. McGregor's garden:
Time = 1 garden / Combined rate = 1 garden / (3/2 gardens per hour) = 2/3 hour

not possible
Answer:
7ab+5
Step-by-step explanation:
add like terms (3ab+4ab=7ab)
5 doesn't have a like term so it stays by itself
Hey there! :)
3ab + 4ab + 5
In order to simplify this, we must add like terms. In addition, when simplifying, you can ONLY add like terms.
Since both "3ab" & "4ab" contain "ab," you are able to combine them together!
When combining like terms, you only add the numerical value, not the letters.
This leaves us with : 7ab + 5
Therefore, your answer is 7ab + 5

Write an explicit rule and recursive rule for a geometric sequence with a second term of 6 and a third term of 12.
Step-by-step answer:
Given:
Geometric sequence with
second term, T2 = 6
third term, T3 = 12
Wants to have the explicit and recursive rules.
Solution:
common ratio, r = 12/6 = 2
Therefore the first term, T1
= second term /r
= 6/2
=3
Thus the absolute rule is
Tn = T1 *r^(n-1) where T1 = 3, r=2. Check: T3 = T1*2^(3-1) = 3*2^2=12 ...good
The recursive rule (depending on the previous term)
Tn = Tn-1*r = 2*Tn-1
The explicit rule for the sequence is a_n = 3 * 2^(n-1), and the recursive rule is a_n = a_(n-1) * 2. These were determined by identifying the common ratio of the sequence as 2.
Explanation:In a geometric sequence, each term is generated by multiplying the previous term by a common ratio. Given the second term (6) and third term (12) in the sequence, we can identify the common ratio by dividing the third term by the second term. So, 12 divided by 6 equals 2. Therefore, the common ratio is 2.
So, the explicit rule (the nth term) of this sequence would be: a_n = a_1 * r^(n-1) = 6 / 2 * 2^(n-1) = 3 * 2^(n-1).
The recursive rule for the sequence would be: a_n = a_(n-1) * r = a_(n-1) * 2.
To summarize, we determined the common ratio to be 2 by dividing the third term by the second term. We then used this ratio to create the explicit and recursive rules for the geometric sequence.

A totem pole casts a 20 meter shadow when the angle of elevation of the sum is 45what is the distance from the top of the totem pole to the end of the shadow
Answer:
20√2 meters (approximately 28.28 m)
Step-by-step explanation:
It may help to make a diagram. Because this is a 45 45 90 triangle, you can use those rules to help solve.
Final answer:
The distance from the top of a totem pole to the end of its shadow, when the angle of elevation of the sun is 45 degrees, is approximately 28.28 meters.
Explanation:
The student has presented a problem that involves using trigonometry to calculate the distance from the top of a totem pole to the end of its shadow when the angle of elevation of the sun is 45 degrees. To solve this, we can use the concept of right-angled triangles and the properties of special triangles, specifically a 45-45-90 triangle where the two legs are congruent. Since the angle of elevation is 45 degrees and the length of the shadow is given as 20 meters, we know that in this special right triangle, the lengths of the two legs are equal. Therefore, the distance from the top of the totem pole to the end of the shadow (the hypotenuse of the triangle) is the length of the shadow times the square root of 2, based on the Pythagorean theorem.
Using the formula hypotenuse = leg × √2, we substitute the leg length of 20 meters to get hypotenuse = 20 m × √2, which equals approximately 28.28 meters.

Ordering using the logarithm property [tex]log_{10}a^{n} =nlog_{10}a[/tex] and [tex]log_{10} 10=1[/tex]
[tex]log_{10}N=log_{10}(16)+0.15tlog_{10}10[/tex]
[tex]log_{10}N=log_{10}(16)+0.15t[/tex]
Clearing t
[tex]t=\frac{log_{10}N-log_{10}(16)}{0.15}[/tex] using the logarith property [tex]log_{10}a-log_{10}b=log_{10}\frac{a}{b}[/tex]
we obtain:

A student rolls a number cube Whose six faces are numbered 1 through 6 what is the sample space for this experiment.
Answer:
It depends on how you define an outcome.
Usually, the outcomes are considered to be the number showing on the top face of the die (number cube) when it comes to rest on a horizontal surface. If that is how you define outcomes, then the sample space is the set of numbers 1–6: {1, 2, 3, 4, 5, 6}.
Step-by-step explanation:
"This experiment" covers a lot of territory. The student could be checking to see if the die stays on the table or falls to the floor. The student could be experimenting to see if the die changes color or makes a certain kind of noise. The experiment could involve the number of times the die rolls over to a new face before it comes to rest. Until the experiment is properly defined, the sample space is unknown.
If the experiment is to see what number shows on the top face of the die at rest on a horizontal surface, then the sample space is presumably the set of numbers 1 through 6.
