Using proportions, it is found that there are 200 rooms in hotel X.

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.

IM TO LAZY TO EXPLAIN BUT ITS RIGHT

The quadratic function f(x) = 4x² + 16x + 8 can be expressed in vertex form

Max's error is in step 3

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

Step-by-step explanation:

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!

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.

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

The speed of Your friend will be 6.55 miles per hour.

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."

If Diego started the race at 11:38 am and finished in 90 minutes, then the time he will finish the race is 12:58 pm, the correct option is D.

An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.

The equations are useful in determination of unknown parameters.

The equations are of various types, such as Trigonometric equations, quadratic equations.

Diego ran a race in 80 minutes, the race started at 11:38 a.m.

The time Diego ran a race in is 80 minutes.

The time he started at 11:38 am

Let he finish the race at x hours.

The equation can be written as,

x = 11:38 + 80 minutes

60 min = 1 hour

80 minutes = 1 hour 20 minutes

x = 11: 38 + 1 :20

x = 12: 58 pm

The time he will finish the race is 12:58 pm.

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

$1322.67

Step-by-step explanation:

Let the total amount that Sarah deposited be $x

using the annuity formula:

A=P[((1+r)^n-1)/r]

A=future value

r=rate

n=number of years

from the information given:

A=$500000

r=2.75%

n=65-42=23 years

p=$x

thus plugging our values in the formula we get:

500000=x[((1+0.0275)^(23)-1)/(0.0275)]

500000=31.50x

x=15,872.04883

She deposited 15,873.04883 per year

The monthly deposit will therefore be:
