Answer:

6 people

Step-by-step explanation:

Since the resort has 380 rooms with space for 6 people, only 6 people can be in these rooms at the same time.

Note: It was not said that each room has space for 6 people but the hotel has space for 6 people

Irrespective of the number of rooms available, the space limit is 6, hence not more than 6 people can be accommodated.

Answer:

The table B represent an inverse variation  

The constant of variation k is 30

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]

Verify table A

For x=3, y=8 ----> [tex]k=y*x[/tex] ----> [tex]k=8*3=24[/tex]

For x=4, y=6 ----> [tex]k=y*x[/tex] ----> [tex]k=6*4=24[/tex]

For x=5, y=4.8 ----> [tex]k=y*x[/tex] ----> [tex]k=4.8*5=24[/tex]

For x=5.5, y=4 ----> [tex]k=y*x[/tex] ----> [tex]k=5.5*4=22[/tex]

The values of k are different

therefore

The table A not represent an inverse variation  

Verify table B

For x=0.1, y=300 ----> [tex]k=y*x[/tex] ----> [tex]k=300*0.1=30[/tex]

For x=0.5, y=60 ----> [tex]k=y*x[/tex] ----> [tex]k=60*0.5=30[/tex]

For x=75, y=0.4 ----> [tex]k=y*x[/tex] ----> [tex]k=75*0.4=30[/tex]

For x=100, y=0.3 ----> [tex]k=y*x[/tex] ----> [tex]k=100*0.30=30[/tex]

All the values of k are the same

therefore

The table B represent an inverse variation  

The equation is equal to

[tex]y*x=30[/tex]

Multiply the number of gallons by the price per gallon:

12.25 gallons x 3.75 per gallon = $45.94 total.

Answer:

Explanation:

This question requires that you find the value of    [tex]a[/tex]    given that:

That is you have to solve the equation for a.

1. Rewrite the equation in form of fractions, convert the mixed number into an improper fraction, and convert the decimal number into fraction too.

[tex]2\frac{1}{7}:(15a)=(5/14)/(0.8)\\ \\ \frac{2+\frac{1}{7} }{15a} =\frac{5/14}{8/10}\\ \\\frac{(14+1)/7}{15a} =\frac{5\times 10}{8\times 14}\\ \\ \frac{15}{7\times 15a} =\frac{50}{112}[/tex]

2. Cross multiply to leave a alone:

[tex]a=15\times 112/(7\times 15\times 50)\\ \\a=1680/5250\\ \\a=0.32[/tex]

Answer:

16 packages

The fraction 27/22, when converted into a decimal and rounded to the nearest tenth, is approximately 1.2.

To convert a fraction to a decimal, divide the numerator by the denominator. In this case, divide 27 by 22.

The question asks to convert the fraction 27/22 into a decimal, rounded to the nearest tenth. First off, we calculate the division of 27 by 22, which gives us approximately 1.227. However, we need to round this figure to the nearest tenth, which results in the value of 1.2. Be sure to understand that when we say 'rounded to the nearest tenth', we refer to the first digit after the decimal point.

the solution is y = 7

Step-by-step explanation:

Given equation is

Answer:

4 over 3 or 4 : 3.

Step-by-step explanation:

See the diagram attached.

Now, The ratio of X's to O's is 12 : 9.

Now, we have to determine another ration for X's to O's.

The image will help us to do that.

There are 12 numbers of X and that can be broken into 3 sets of X with 4 X in each set. Hence, 12 = 3 × 4

Again, there are 9 numbers of O and that can be broken into 3 sets of O with 3 O in each set. Hence, 9 = 3 × 3

Therefore, the ratio of X's to O's is 12 : 9 ≡ (3 × 4) : (3 × 3) ≡ 4 : 3

{Cancelling 3 from each term} (Answer)

Answer:

The answer is 4 over 3.

Step-by-step explanation:

if you look at the image all you have to do is count the X's on the top, and that's the top of your fraction, then count the bottom number, that's the bottom of your fraction.

4 on the top three on the bottom so your fraction/ratio is 4 over 3!

Answer:

The number of movies that can can fit on shelf of 5 feet is 9 .

Step-by-step explanation:

Given as :

The measure of each movies case = 7 inches wide

Let the number of movies for 5 feet wide = n

Now ,

∵ 1 feet = 12 inches

∴ 5 feet = 12 × 5 = 60 inches

I.e 5 feet = 60 inches

Now, Again

For 7 inches wide  , the number of movies = 1

So, for 1 inch wide case, the number of movies = [tex]\frac{1}{7}[/tex]

∴ For 60 inches wide case, the number of movies = [tex]\frac{1}{7}[/tex] × 60

I.e For 60 inches wide case, the number of movies = 8.57 ≈ 9

Hence the number of movies that can can fit on shelf of 5 feet is 9 . Answer

The equation [tex]A=5000(1.000958333)^{108}[/tex] will determine how much money Bevo will have in his account after 9 years

Step-by-step explanation:

The formula for compound interest, including principal sum is

[tex]A=P(1+\frac{r}{n})^{nt}[/tex] , where:

Bevo has $5000 to invest. Bank A offers a savings account that has an APR of 1.15% and compounds monthly

We need to find Which equation will determine how much money Bevo will have in his account after 9 years

Because there is no choices we will write the equation

∵ Bevo has $5000 to invest

∴ P = 5000

∵ Bank A offers a savings account that has an APR of 1.15%

   and compounds monthly

∴ r = 1.15% = 1.15 ÷ 100 = 0.0115

∴ n = 12 ⇒ compounds monthly

∵ t = 9

- Substitute all of theses values in the formula below

∵ [tex]A=P(1+\frac{r}{n})^{nt}[/tex]

∴ [tex]A=5000(1+\frac{0.0115}{12})^{(12)(9)}[/tex]

∴ [tex]A=5000(1.000958333)^{108}[/tex]

The last one

The equation 7 - x = 3 is best modeled by the situation where the original price of a book at $7 is lowered by an amount of $4 to reach the final price of $3.

The given equation 7 - x = 3 can be used to model a situation where the price of a book, originally $7, is reduced by some amount to $3. After solving the equation by subtracting 7 from both sides and then multiplying by -1, we get x = 4. This means the amount reduced from the original price is $4, which is consistent with a price reduction scenario: the book's original price was $7, and it was reduced by $4, bringing the final price to $3.

the factored form of the expression [tex]\(3x^2 + 7x - 6\) is \((3x - 2)(x + 3)\).[/tex]

To factor the expression [tex]\(3x^2 + 7x - 6\),[/tex] we need to find two numbers that multiply to give [tex]\(3 \times (-6) = -18\)[/tex] and add to give the middle coefficient, (7)

The two numbers that meet these criteria are [tex]\(9\) and \(-2\).[/tex]

Now, we can rewrite the middle term \(7x\) as the sum of these two terms:

[tex]\[3x^2 + 9x - 2x - 6\][/tex]

Next, we group the terms and factor by grouping:

[tex]\[3x(x + 3) - 2(x + 3)\][/tex]

Now, we can factor out the common factor [tex]\(x + 3\):[/tex]

[tex]\[(3x - 2)(x + 3)\][/tex]

So, the factored form of the expression [tex]\(3x^2 + 7x - 6\) is \((3x - 2)(x + 3)\).[/tex]
