Answer:
[tex]x=5[/tex]
Step-by-step explanation:
We have the equation:
[tex]34\cdot 3^{x-2}-2\cdot 3^{x-3}=0.8\cdot 10^{x-2}+10^{x-3}[/tex]
Let's simplify this a bit. Let [tex]u=x-2[/tex]. Then [tex]u-1=x-3[/tex]. We can substitute the exponents:
[tex]34\cdot3^u-2\cdot 3^{u-1}=0.8\cdot 10^u+10^{u-1}[/tex]
Use the properties of exponents, we can write [tex]3^{u-1}=\frac{3^u}{3}[/tex]. We can do the same thing on the right. So:
[tex]34\cdot3^u-2\cdot \frac{3^u}{3}=0.8\cdot 10^u+\frac{10^u}{10}[/tex]
We can now factor out a [tex]3^u[/tex] from the left and a [tex]10^u[/tex] on the right. This yields:
[tex]3^u(34-2\cdot\frac{1}{3})=10^u(0.8+ \frac{1}{10})[/tex]
Evaluate the expressions within the parentheses:
[tex]3^u(34-\frac{2}{3})=10^u(\frac{9}{10})[/tex]
Evaluate:
[tex]3^u(\frac{100}{3})=10^u(\frac{9}{10})[/tex]
Now, let's multiply both sides by [tex]\frac{3}{100}[/tex]. So:
[tex]3^u=10^u(\frac{9}{10})(\frac{3}{100})[/tex]
Also, let's divide both sides by [tex]10^u[/tex]. Multiply on the right:
[tex]\frac{3^u}{10^u}=\frac{27}{1000}[/tex]
Therefore:
[tex]3^u=27\text{ and } 10^u=1000[/tex]
We can now substitute back u. Notice that 27 is the same as 3 cubed and 1000 is the same as 10 cubed. So:
[tex]3^{x-2}=3^3\text{ and } 10^{x-2}=10^3[/tex]
Since they have the same base, their exponents must be equal. Therefore:
[tex]x-2=3[/tex]
Add 2 to both sides:
[tex]x=5[/tex]
So, the value of x is 5.
And we're done!
The X Hotel has an occupancy rate of 97% during busy season and 62% during the rest of the year. It makes $80 (revenue - variable costs) per room per night. Busy season accounts for 30% of the year. After covering it's $4M in annual fixed costs, the total profit for the Pinkerton Hotel was $4,468,000. How many rooms are in the X Hotel? 400 O 650 150 200
Using proportions, it is found that there are 200 rooms in hotel X.
What is a proportion?A proportion is a fraction of a total amount.
The X Hotel has an occupancy rate of 97% during busy season(30% of the year) and 62% during the rest of the year(70%), hence the mean occupancy rate is of:
R = 0.3 x 97% + 0.62 x 70% = 72.5%.
The total profit for the Pinkerton Hotel was $4,468,000, hence considering that it makes $80 per room per night, in a 365-day year:
80N x 0.725 x 365 = 4,468,000
N = 4,468,000/(80 x 0.725 x 365)
N = 211.
Which is closest to 200, hence, there are 200 rooms in hotel X.

Max rewrote the function f(x) = 4x² + 16x + 8 in vertex form by completing the square.
He concluded that the vertex is (-2, 4), which was incorrect. Consider Max's work, listed below.
In which step did Max make a mistake?
Step 1: f(x) = 4x² + 16x + 8
Step 2: f(x) = 4(x² + 4x) +8
Step 3: f(x) = 4(x² + 4x + 4) +8-4
Step 4: f(x) = 4(x + 2)² +4
The quadratic function f(x) = 4x² + 16x + 8 can be expressed in vertex form
Max's error is in step 3
How to determine the error in the function?The function is given as:
[tex]f(x) = 4x^2 + 16x + 8[/tex]
Factor out 4
[tex]f(x) = 4(x^2 + 4x) + 8[/tex]
Take the coefficient of x
[tex]k = 4[/tex]
Divide by 2
[tex]k/2 = 2[/tex]
Square both sides
[tex](k/2)^2 = 4[/tex]
Add and subtract 4 to the bracket
[tex]f(x) = 4(x^2 + 4x + 4 - 4) + 8[/tex]
Expand
[tex]f(x) = 4(x^2 + 4x + 4) + 8 - 16[/tex]
By comparing the above equation to step 3 of Max solution, we can determine that Max's error is in step 3

While shopping, Kyla found a dress that she would like to purchase, but it costs $49.50 more than she has. Kyla charges $5.50 an hour for babysitting. She wants to figure out how many hours she must babysit to earn $49.50 to buy the dress.
Answer:
9 hours
Step-by-step explanation:
We can do this 2 ways but I think you will want this the easiest way :)
So we can divide:
49.50/5.50
9
Or we can multiply and keep multiplying 5.50 by different numbers until we get 49.50 or over (this way will take longer)
5.50 x 1
5.50 x 2
and so on and so fourth
With the first way we figued out she will need to babysit for 9 hours :)

In the equation 0.44 x 0.72 = n, what is the value of n?
Answer:n=0.3168
Step-by-step explanation:
Answer:
n = .3168
Step-by-step explanation:
Multiply .44 by .72.
You can use a calculator to do this or do it by hand.
If you choose to do it by hand, multiply using long multiplication without paying mind to the decimals, and then when you are finished, add the decimal four places to the left (at the very beginning of the number you should get). So, 3168 becomes .3168, or your final answer.

6. The perimeter of a rectangle is 48 feet, and the length is 16 feet. What is the area?
Answer: 256 ft²
Step-by-step explanation:
The perimeter is calculated by:
P = 2l + 2w
so we know:
48 = 2(16) + 2w
48 - 32 = 2w
w = 16 feet
So the area is 16 x 16 = 256 ft²

yes because it would take about 6 hours and 55 minutes.
Step-by-step explanation:
26.2 × 4=6.55
Answer 6.55 or 6 hours and 55 minutes
The speed of Your friend will be 6.55 miles per hour.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
A marathon is approximately 26.2 miles. Your friend says that if you continue to run at this speed, you will not be able to complete a marathon in less than 4 hours.
The speed of Your friend will be
S = 26.2 / 4
S = 6.55 miles per hour

At a birthday party, 5 boys and 3 girls are seated in a row. How many different arrangements are possible if there are no boys between any two girls?
Answer:
Basic Concept:
Since there are no boys between 2 girls, we will take the 3 girls as 1 single unit and permute the seats
We have 6 slots (5 for boys and 1 for all 3 girls)
We have 6 slots and 6 people to sit on them (taking the 3 girls as one)
Permutations:
So, the total number of seating arrangements is 6P6
which will be equal to 6 factorial (6P6 = [tex]\frac{n!}{n! - r!}[/tex] = [tex]\frac{6!}{6! - 6!}[/tex] = 6! (since 0! = 1))
Total possible seating arrangements = 6!
Total possible seating arrangements = 720

Original price: $340.00
markdown 50%.
Answer:
50/100(50%) x 340 = $170
If there is a 50% markdown, you would need to take 50%(1/2) away from the original price.
Answer:
$170
Step-by-step explanation:
Given the following question:
50% of 340
To find the answer we must first find 50% of 340 by using the formula to calculate percentages, and then subtract that answer from the original price to have our markdown.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{50\times340}{100}[/tex]
[tex]50\times340=17000[/tex]
[tex]17000\div100=170[/tex]
[tex]=170[/tex]
Now subtract from original price:
[tex]340[/tex]
[tex]340-170=170[/tex]
[tex]=170[/tex]
The new price after a 50% markdown is "$170."
Hope this helps.
