Answer:

1/5

In decimal = 0.2

Step-by-step explanation:

A box holds a white button, a brown button and a black button.

Hence:

Number of white button= 1

Number of brown button= 1

Number of black button= 1

Total number of buttons = 3

The probability of picking a white button then without replacing it, picking a brown button on the second pick is :

= P(White) × P(Brown) [ without replacement]

= 1/3 × 1/2

= 1/5

In decimal = 0.2

Answer:

18

Step-by-step explanation:

We know that the girl to boy ratio is 8:6 and we are told that there are 24 girls.

We multiply 8 by 3 to give us 24, so if we multiply by 3 on one side we must multiply by 3 on the other side.

This gives us a final answer of 24:18, so there are 18 boys in the class.

Answer:

las vidas una carnival

Step-by-step explanation:

Answer:

We know that the hotel charges 12.5% in taxes (or 0.125 in decimal form).

Then if the initial cost of the hotel, without taxes, is a, the price with taxes will be:

f(a) = a + 0.125*a = 1.125*a

And the hotel also charges a fee of $25 for each day (that is not subject to taxes) then if the total cost, with taxes, is b, the actual cost will be:

g(b) = b + 25.

Then:

a = The cost of the hotel room without sales tax or the resort fee.

f(a) and b= The cost of the hotel room and sales tax, but without the resort fee

g(b) = The cost of the hotel room, with sales tax and the resort fee.

Answer:

Answer is choice C. We distribute the outer 2 into each of the inner terms (x and -4). Choice D is a trick answer because a lot of the time you might forget to multiply the 2 by the -4 inside the parenthesis (common mistake).

2 times x = 2x

2 times -4 = -8

2 times (x-4) = 2x-8

Side Note: Another path to solve this equation is to divide both sides by 2, then to add 4 to both sides.

Step-by-step explanation:

Answer:

c

Because...

It has the same slope.

Explanation:

The lowest point occurs when y = 0.

The highest point occurs when y = 12.

The range is therefore [tex]0 \le y \le 12[/tex] which converts to [tex][0,12][/tex] which is interval notation. The square brackets tell us to include the endpoints. So we're saying that y can be anything between 0 and 12, including both endpoints.

The range is the set of all possible y outputs of a function.

Step-by-step explanation:

Answer:

5x^2 + 17xy - 12y^2

5x^2 + 5xy + 12xy - 12y^2

5x (x - y ) + 12 y ( x - y )

(5x + 12y ) (x-y).

Step-by-step explanation:

The answer is : (-4, 9)

The given function is:

f(x) = -x^2 - 8x - 7

To find the vertex of the parabola, we need to complete the square as follows:

f(x) = -(x^2 + 8x) - 7

= -(x^2 + 8x + 16) + 16 - 7

= -(x + 4)^2 + 9

Hence, the vertex is (-4, 9).

Since the coefficient of x^2 is negative, the parabola opens downward.

To find the y-intercept, we set x = 0:

f(0) = -0^2 - 8(0) - 7 = -7

Therefore, the y-intercept is (0, -7).

To sketch the graph, we plot the vertex (-4, 9) and the y-intercept (0, -7). Since the parabola opens downward, it will have a maximum value at the vertex. We can also plot a few other points by choosing values of x and calculating the corresponding values of y.

Therefore, the vertex is (-4, 9).

Answer:

x = −1

Step-by-step explanation:

Answer:

x = -1

Step-by-step explanation:

7 - 7 + 16x - 12x - 6 + x = 12x - 13x - 12

Combine like terms

−6 + 5x = -x - 12

Add x to both sides

6x -6 = -12

Add -6 to both sides

6x = -6

Divide 6 to both sides

6x/6 = -6/6

x = -1

Answer:

The lengths of the sides of the rectangle are 13 inches and 15 inches

Step-by-step explanation:

The perimeter of a rectangle

Given the two sides of a rectangle a and b. The perimeter of the rectangle is:

[tex]P=2(a+b)[/tex]

We are given the perimeter of a rectangle as:

[tex]P=8(2x+1)[/tex]

And each side has a length of 3x+4 and 4x+3. Calculating the perimeter:

[tex]P=2(3x+4+4x+3)=2(7x+7)[/tex]

We set up the equation:

[tex]8(2x+1)=2(7x+7)[/tex]

Dividing by 2:

[tex]4(2x+1)=7x+7[/tex]

Operating:

[tex]8x+4=7x+7[/tex]

Subtracting 7x:

[tex]x+4=7[/tex]

Subtracting 4:

x=3

The length of each side is:

3x+4=3*3+4=13

4x+3=4*3+3=15

The lengths of the sides of the rectangle are 13 inches and 15 inches

Answer:

[tex]\huge\boxed{\text{0.17 hours}}[/tex]

Step-by-step explanation:

We can create two ratios to find how long you can use a bike for one dollar.

Let's set up a ratio in the form [tex]\frac{cost}{hours}[/tex]

We know it costs $23 to ride for 4 hours, so we can make the fraction [tex]\frac{23}{4}[/tex].

We also know that for $1, we'll have some unknown time for the bike. We can represent this as [tex]\frac{1}{x}[/tex].

Since the constant of proportionality has to be the same, we can set these two ratios equal to each other.

[tex]\frac{23}{4}=\frac{1}{x}[/tex]

We can now solve for x by cross multiplying.

[tex]1 \cdot 4 = 4\\\\4 \div 32 \approx 0.17[/tex]

So $1 will get you around 0.17 hours of bike time.
