Answer: Sally will catch up with Jane after 50 minutes.

Step-by-step explanation:

Since we have given that

Speed of Jane of biking = 12 mph

After 10 minutes,

Speed of Sally of biking = 15 mph

Let the distance be 'x'.

According to question, our required equation becomes,

[tex]\dfrac{x}{12}-\dfrac{x}{15}=\dfrac{10}{60}\\\\\dfrac{5x-4x}{60}=\dfrac{1}{6}\\\\\dfrac{1x}{60}=\dfrac{1}{6}\\\\x=10\ miles[/tex]

Thus, total distance would be 10 miles.

So, the time taken by Sally to catch up with Jane is given by

[tex]\dfrac{10}{12}=\dfrac{5}{6}\times 60=50\ minutes[/tex]

Hence, Sally will catch up with Jane after 50 minutes.

Answer:

432ft²

Step-by-step explanation:

The dimensions for one wall= 12' by 9'

Area of the wall is given by = width × height

Given width of room = 12' and height of wall =9 feet

Area for one wall= 12×9=108ft²

Area for four walls= 108 × 4=432ft²

Answer:

They will cover 432 feet²

Step-by-step explanation:

* Lets study the information in the problem

- The room has floor with dimensions 12 feet by 12 feet

- The height of the room is 9 feet

- The room has floor and ceiling with same dimensions

- The room has four walls with dimensions 12 feet and 9 feet

- The need to cover the 4 walls

- Each wall shaped a rectangle with base 12 feet and height 9 feet

- The area of the rectangle = base × height

* Now lets solve the problem

∵ The base of the wall = 12 feet  

∵ The height of the wall = 9 feet

∵ The area of the wall = base × height

∴ The area of one wall = 12 × 9 = 109 feet²

- The room has four identical walls

∴ The area of the 4 walls = 4 × 108 = 432 feet²

* They will cover 432 feet²

Final answer:

Bred can paint the wall in 6 different ways using 8 horizontal stripes, considering a maximum of 2 colors out of blue, red, and white with enough paint for 5 stripes of each color.

Explanation:

The question at hand involves combinatorics, which is a branch of mathematics dealing with combinations and permutations. Bred can paint a wall with 8 horizontal stripes using at most 2 colors from the options of blue, red, and white, with enough paint for 5 stripes of each color. Since he is using at most 2 colors, we need to calculate the number of combinations for each pair of colors as well as the individual colors. The possible pairs with their respective numbers of combinations are blue-red, blue-white, and red-white. For blue-red and blue-white, he can paint 5 blue stripes and 3 stripes of the other color, while for red-white, he can paint 5 red stripes and 3 white stripes.

The combinations for each pair would be:

Blue-Red: 5 blue + 3 red

Blue-White: 5 blue + 3 white

Red-White: 5 red + 3 white

Additionally, Bred can choose to use only one color. Thus, for each of the colors blue, red, and white, there will only be one way to paint the wall.

Therefore, the total different ways Bred can paint the wall are the sum of the combinations for each pair plus the individual color options:

For pair Blue-Red: 1 way

For pair Blue-White: 1 way

For pair Red-White: 1 way

Only Blue: 1 way

Only Red: 1 way

Only White: 1 way

Adding these up gives us a total of 6 different ways to paint the wall.

For this case we have that by definition, the domain of a function, is given for all the values for which the function is defined.

We have:

[tex]f (x) = \frac {x + 1} {x ^ 2-6x + 8}[/tex]

The given function is not defined when the denominator is equal to zero. That is to say:

[tex]x ^ 2-6x + 8 = 0[/tex]

To find the roots we factor, we look for two numbers that when multiplied give as a result "8" and when added as a result "-6". These numbers are:

[tex]-4-2 = -6\\-4 * -2 = 8[/tex]

Thus, the factored polynomial is:

[tex](x-4) (x-2) = 0[/tex]

That is to say:

[tex]x_ {1} = 4\\x_ {2} = 2[/tex]

Makes the denominator of the function 0.

Then the domain is given by:

All real numbers, except 2 and 4.

Step-by-step explanation:

bc is along a straight line with section 4 straight lines are 180° if bc is 30° then 180°-30°=150°

Answer:

The measure of ∠4 is 150°

Step-by-step explanation:

Given the figure in which BD is the diameter of circle and

m∠1=100°

m(arc BC)=∠3=30°

we have to find the measure of ∠4.

As BD is a straight line as BD is diameter therefore

∠4 and ∠3 forms a linear pair

⇒ ∠4 and ∠3 are supplementary i.e these angles adds up to 180°

∠4 + ∠3 = 180°

∠4+30°=180°

∠4=180°-30°=150°

Hence, the measure of ∠4 is 150°

The domain of the given function is:

                  [tex]x\geq 5[/tex] i.e. [5,∞)

Domain of a function--

The domain of a function is the set of all the possible values of x for which the function is defined.

That is it is the collection of all the points except the excluded values of the function.

The function f(x) is a square root function which is given by:

          [tex]f(x)=2\sqrt{x-5}[/tex]

We know that the domain of the function depends on the domain of the square root quantity.

We know that: a square root function is well defined when the quantity under the square root is non-negative

i.e.

[tex]x-5\geq 0\\\\i.e.\\\\x\geq 5[/tex]

Answer: You've probably already seen the basic method for graphing straight lines; namely, make a T-chart, plot some points, put your ruler against them, and draw the line. But the "nice" form of a straight line's equation (being the slope-intercept form, y = mx + b) can make graphing even simpler and faster.

Step-by-step explanation:

The equation of the line must be 2x - 1

The equation of the line that represents an equation of a line with a slope of 2 and a point on the line of (1, 2) can be written in the form:

[tex]y-y_0=m(x-x_0)[/tex]

m is the slope of the line

(x0, y0) is the point on the line

Substitute the given parameters into the formula to have:

[tex]y-2=2(x-1)\\y - 1= 2x - 2\\y = 2x -2+1\\y = 2x-1[/tex]

Hence the equation of the line must be y= 2x - 1

Answer:

(f * g)(x) = 4x^3 - x^2

[tex]4x^{3}-x^{2}[/tex]

Step-by-step explanation:

We have been given the following functions;

f(x) = 4x - 1

g(x) = x^2

We are required to determine;

(f * g)(x)

This simply means we shall be finding the product of the two functions given;

(f * g)(x) =  f(x)*g(x)

(f * g)(x) =  x^2 * (4x - 1 )

we open the brackets by multiplying each term by x^2

(f * g)(x) = x^2(4x) + x^2(-1)

(f * g)(x) = 4x^3 - x^2

Answer:

C) 24

Step-by-step explanation:

1. Since the perimeter of a triangle is the sum of its three sides, you can write the following expression, solve for x and get the value of each side.

[tex]2x+(2x+2)+(2x+4)=24\\2x+2x+2+2x+4=24\\6x+2+4=24\\6x+6=24\\6x=24-6\\6x=18\\x=\frac{18}{6}\\x=3[/tex]

2. So, replacing the value of x, you can calculate the values of each side of the triangle:

First side:

[tex]2x=2(3)=6[/tex]

Second side:

[tex](2x+2)=(2(3)+2)=6+2=8[/tex]

Third side:

[tex](2x+4)=(2(3)+4)=6+4=10[/tex]

As the larger side is the third one, it is the hypotenuse. So, the base and the  height.

3. The formula to find the area of the right triangle is given by the expression:

[tex]A=\frac{b*h}{2}[/tex]

Where b is the base and h is the height of the triangle, so replacing the values we found, we have the following:

[tex]A=\frac{8*6}{2}[/tex]

[tex]A=\frac{48}{2}[/tex]

[tex]A=24[/tex]

Therefore the answer is C) 24

Answer:

[tex]h(-9)=-\frac{2}{33}[/tex]

Step-by-step explanation:

The given expression is [tex]h(r)=\frac{2}{3r-6}[/tex]

We want to find the value of h(-9).

We substitute r=-9 to obtain:

[tex]h(-9)=\frac{2}{3(-9)-6}[/tex]

We multiply out to obtain:

[tex]h(-9)=\frac{2}{-27-6}[/tex]

We simplify the denominator to obtain:

[tex]h(-9)=\frac{2}{-33}[/tex]

This is the same as:

[tex]h(-9)=-\frac{2}{33}[/tex]

The value of h(-9) is 0. Function substitution is a mathematical technique that involves replacing a variable with an expression or function, simplifying calculations and solving equations by making them more manageable.

To find h(-9), you simply substitute -9 for r in the function h(r):

h(-9) = (2/3) * (-9) - 6

Now, calculate it step by step:

h(-9) = (-18/3) - 6

Since -18/3 is -6, the equation simplifies to:

h(-9) = -6 - 6

Now, add -6 and -6:

h(-9) = -12

So, the value of h(-9) is -12.

Answer:

The number is 6

Step-by-step explanation:

We let the number be x. If we subtract -2 from x we obtain the following result;

x - (-2)

This can be simplified to yield the following result;

x - (-2) = x + 2

we use the rule that negative multiplied by negative yields a positive sign.

We are further informed that the result of the above operation is 8, therefore;

x + 2 = 8

Solving for x yields;

x = 8 -2

x = 6

the number that we are looking for is 6.

The question asks us to find the number that results in 8 when -2 is subtracted from it. To solve this, we can set up an equation. Let x be the number we are looking for:

x - (-2) = 8

We know that in subtraction, we change the sign of the subtracted number and then follow the addition rules. This means our equation becomes:

x + 2 = 8

Now we subtract 2 from both sides to find the value of x:

x = 8 - 2

x = 6

Thus, the number that we are looking for is 6.
