Forty-five states in a country have​ four-star hotels. Assume the country has 50 states.​ (a) What fraction of the states can claim at least one​ four-star hotel?​ (b) How many states do not have a​ four-star hotel?​ (c) Write the fraction of states without a​ four-star hotel.

Answer:

a) 61

The friend's ages are consecutive, therefore they are each one year apart. There are 3 friends whose ages add up to 180 in total.

[tex]180 / 3 = 60[/tex]

In order to make three consecutive numbers, subtract one and add one to 60.

[tex]60 - 1 = 59\\60 + 1 = 61[/tex]

You get 59, 60, and 61.

61 is the oldest age, that's your answer.

1. 3p: Add 6 to negative 3, and carry over the "p"

3. 6x: Subtract 1 from 7 and carry over the "x"

5. -4v: Add 6 to negative 10 and carry over the "v"

7. -4r + 9: Add 5 to -9 and carry over the "r". Then put "+9" after the variable, since the other 9 was by itself.

9. 14n: Add 5 to 9 and carry over the "n".

Answer: The correct option is second, i.e., [tex]g(x)=3f(x)[/tex].

Explanation:

A functions g(x) is stretch or compressed of graph of function f(x) is defined by the equation,

[tex]g(x)=kf(x)[/tex]

Where, k is a constant and it shows the compress or stretch factor.

If k>0, then it is a stretch factor and the graph of f(x) is stretched by factor of k.

If k<0, then it is a compress factor and graph of f(x) is compressed by factor k.

Since the graph of g(x) is a vertical stretch of the graph of function f(x) ​​by a factor of 3, therefore,

[tex]g(x)=3f(x)[/tex]

So, the option second is correct.

|x| = 5

x = 5 or x = -5

You need a graph that has a closed dot on -5 and a closed dot on 5.

Answer

24 quarts of green paint should be mixed with 4 cups of black paint.

That is (96 cups)

Step by step explanation

Jasper Green mix 4 quarts of green paint with 2/3 cups of black paint.

Let's convert 4 quarts into cups.

1 quart = 4 cups

4 quarts = 16 cups

Here mix 16 cups of green paint with 2/3 cups of black paint.

Let's use the proportion

Green paint                      Black paint

16                                          2/3

x                                            4

16/x =2/3 divided by 4

[tex]\frac{16}{x}  = \frac{2/3}{4}[/tex]

Cross multiplying, we get

16*4 = 2/3 x

64 = 2/3 x

x = 64/(2/3)

x = 64 * 3/2

x = 192/2

x = 96 cups

96 cups of green paint should be mixed with 4 cups of black paint.

We can covert 96 cups into quarts by dividing by 4

96/4 = 24 quarts

24 quarts of green paint should be mixed with 4 cups of black paint.

Thank you.

To make Jasper Green with 4 cups of black paint, you need to create a proportional relationship and solve for the amount of green paint needed, which is 96 cups.

To solve this, we need to set up a proportional relationship between the amounts of green paint and black paint. In the first mixture, we have 4 quarts of green paint for every 2/3 cups of black paint. Converting 4 quarts to cups (since 1 quart = 4 cups), we get 16 cups of green paint.

Then we can set up the proportion: (16 cups green / 2/3 cups black) = (x cups green / 4 cups black). Cross multiplying and solving for x, we get x = 96 cups of green paint. So, to make Jasper Green with 4 cups of black paint, you need to mix in 96 cups of green paint.

What is your question exactly??

Answer:Your Answer of the probability would determindedly be 3/25.

Step-by-step explanation:

a) 9 + -5 =  9-5 = 4

b)  3 +-4 = 3 -4 = -1

c) -8 + 6 = -2

We are given

First expression:

Third expression:

We used simplification

Answer:

The variable p represent the number of packages.

Step-by-step explanation:

As 4.45 is the cost of tomatoes, and 4.45p represents the cost of the tomatoes for a number of packages, we can say that p represent the number of packages.

Given polynomial is:

[tex]-12x^{5}-6 x^{4}+5 x^{3}-x^{2}-12x+9[/tex]  ..... Lets say it is "a"

We have to subtract a polynomial from this above one, to get the answer as:

[tex]-19x^{5}-8x^{4}+8x^{3}-2x^{2}-18x+19[/tex]   ..... Lets say it is "c"

Lets say we have to subtract "b" so we have : [tex]a-b=c[/tex] or we can say [tex]a-c=b[/tex]

So, we will subtract "c" from "a" and get:

[tex]7x^{5}+2x^{4}-3x^{3}+x^{2}+6x-10[/tex]

Hence, this is the answer.

= [tex]\frac{3 (ft)}{2(in)} by \frac{2(3)(ft)}{4(in)}[/tex]

= [tex]\frac{3 (ft)}{2(in)} by \frac{3(ft)}{2(in)}[/tex]

Scale factor is: [tex]\frac{3(ft)}{2(in)}[/tex]

Answer:

Step-by-step explanation:

Every transformation has an original figure and a transformed figure.

In order to find the scale factor fo the transformation, we need to divide the transformed dimensions by the original ones.

So, in this case, the poster originally had 3 feet by 2 feet. Then, the reproduced artwork has 2 inches by 1 1/3 inches. Before we divide, we need to transform feet to inches.

We know that 1 feet equals 12 inches, that means

[tex]3ft \frac{12in}{1ft} =36in[/tex]

[tex]2ft\frac{12in}{1ft}=24in[/tex]

Then, we do the divisions

[tex]\frac{36in}{2in}=18\\\frac{24in}{1\frac{1}{3}in }=\frac{24in}{\frac{4}{3}in }=\frac{96}{3}=32[/tex]

Therefore, the scale factor is [tex]\frac{18}{32}=\frac{9}{16}[/tex]

Given cost function C(a) = 7.5a, where a is the number of T-shirts.

Let us complete table.

We need to plug a=1,2,3,4 in above function to get the costs to complete the table.

For a =1

C(1)= 7.5(1) = 7.50

For a =2

C(2)= 7.5(2) = 15.00

For a =3

C(3)= 7.5(3) = 22.50

For a = 4

C(4)= 7.5(1) = 30.00

In order to find the common difference we need to find the diffrences of costs 15-7.50 = 7.50

22.50-15.00=7.50.

a represents the number of T-shirts.

Domain of a is the numbers we can take for a.

So, we can take value for a as 0 or greater value.

Therefore, domain for a would be a is gerater than or equal to 0.

2(b + 3) - (7 + b) = -7

2b + 6 - 7 - b = -7

b = -6 + 7 - 7

b = -6

To solve this first distribute the 2, and then distribute the negative sign.

2(b+3)-(7+b)=-7

2b+6-7-b=-7

Combine like terms.

2b+(-b)=b

6+(-7)=-1

b-1=-7

Add 1 on both sides of the equation.

b-1+1=-7+1

b=-6

To determine the greatest number of people Oscar and Julie can invite within their budget, we can set up an inequality and solve for the variable 'x'. The total cost equation is $90 + $31x ≤ $2,000. Solving this inequality, we find that the greatest number of people they can invite is 61.

To determine the greatest number of people that Oscar and Julie may invite and still stay within their budget, we need to set up an inequality based on the given information. Let's denote the number of people they invite as 'x'. The total cost of the reception hall is $90 (cleanup fee) + $31 (per person) * x (number of people). This should be less than or equal to their budget of $2,000. So, the inequality is 90 + 31x ≤ 2000. To solve for 'x', we need to isolate the variable. Subtracting 90 from both sides, we have 31x ≤ 1910. Dividing both sides by 31, we find x ≤ 61.935. Since we can't have a fraction of a person, the greatest number of people they can invite is 61.
