Final answer:

To find the value of x, set the expressions equal to each other and solve for x.

Explanation:

To find the value of x in the given equation, we need to set the two expressions equal to each other and solve for x. So, we have:

19x - 36 = 6x + 31

Subtracting 6x from both sides, we get:

13x - 36 = 31

Adding 36 to both sides, we get:

13x = 67

Dividing both sides by 13, we get:

x = 67/13

So the value of x is approximately 5.15.

Final answer:

The slope of the line passing through the points (10,4) and (-2, 17) is calculated using the slope formula and is approximately -1.08.

Explanation:

To find the slope for the line passing through the two points (10,4) and (-2, 17), we use the slope formula which is (change in y)/(change in x) or (y2 - y1) / (x2 - x1). Applying this formula to our points:

m = (17 - 4) / (-2 - 10)

m = 13 / -12

m = -1.0833...

So, the slope of the line that passes through the points (10,4) and (-2, 17) is approximately -1.08.

Answer:

[tex](F+G)x=2x^2+4x-16[/tex]

[tex]Domain[/tex] [tex]=(-\infty,\infty)[/tex]

Step-by-step explanation:

Given that

[tex]F(x)=2x^2+3x-15[/tex]

and  [tex]G(x)=x-1[/tex]

then   [tex](F+G)x = F(x)+G(x)[/tex]

[tex]=(2x^2+3x-15)+(x-1)\\=2x^2+3x-15+x-1\\\\(F+G)x=2x^2+4x-16[/tex]

Domain

since it is a polynomial of degree [tex]2[/tex], the domain will be whole real line  

[tex]domain[/tex] [tex]=(-\infty,\infty)[/tex]

Final answer:

To perform the function operation (F+G)(X), add the functions f(x) and g(x) together to get (F+G)(X) = 2x² + 4x - 16. The domain of this function is all real numbers.

Explanation:

To perform the function operation (F+G)(X), where f(x) is given as 2x² + 3x - 15 and g(x) is x - 1, we simply add the two functions together:

(F+G)(X) = f(x) + g(x)

(F+G)(X) = (2x² + 3x - 15) + (x - 1)

This simplifies to:

(F+G)(X) = 2x² + (3x + x) - (15 + 1)

(F+G)(X) = 2x² + 4x - 16

The domain for this new function is all real numbers, since there are no restrictions such as division by zero or taking the square root of a negative number that would limit the values that x can take.

Answer:

the answer is the first graph

Step-by-step explanation:

because the negative points are not viable

The graph of the equation y = 5.5x is shown in the picture and the slope of the line is positive, which is 5.5 option first is correct.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a linear equation in the form of slope:

y = 5.5x

Slope of the line m = 5.5

Slope is positive, which means the line goes down to up.

We can plot the graph of the equation y = 5.5x

Option first On a coordinate plane, x-axis is numbered negative 5 to positive 5 in increments of 1, and the y-axis is numbered negative 27.5 to 27.5 in increments of 5.5. A straight line with a positive slope begins at point (0, 0) and ends at point (5, 27.5) is correct.

Thus, the graph of the equation y = 5.5x is shown in the picture and the slope of the line is positive, which is 5.5 option first is correct.

Part C : [tex]V = \frac{4}{3}\pi r^{3}[/tex]

Step-by-step explanation:

Part A :

The volume of the silo includes the volume of a hemisphere and a cylinder.

So, the total volume

[tex]V = \frac{2}{3}\pi r^{3} + \pi r^{2}h[/tex]

⇒ [tex]V = \frac{2}{3} \times \pi (8)^{3} + \pi (8)^{2} (20)[/tex]

⇒ [tex]V = \frac{1024}{3}\pi + 1280\pi = 1621\frac{1}{3}\pi[/tex] cubic meters. (Answer)

Part B :

The volume of the cylindrical cup with height 15 cm and base radius 6 cm is given by

[tex]V = \pi r^{2}h = \pi (6)^{2} (15) = 540\pi[/tex] cubic cm.

Therefore, Mary can put 540π cubic cm of water in the cup with out it overflowing. (Answer)

Step-by-step explanation:

3(1/6+2/9)+(-2)

3*7/18 = 21/18 = 1 1/6

1 1/6 - 2 = -5/6

Answer:

165 people

Step-by-step explanation:

If there are 105 woman then there are going to be 60 men because 105/7=14, so you multiply 4*15 and get 60. 60 + 105= 165. So the total employees will be 165.

The total number of employees is the sum of men and women, which is 105 (women) + 60 (men) = 165 employees.

To find the total number of employees, calculate the number of men from the given ratio 4:7 and the number of women (105), and then add the number of men to the number of women to get the total.

The question is about finding the total number of employees in a company given the ratio of men to women and the number of women.

Let's use the provided ratio of men to women, which is 4 to 7, to calculate the number of men.

Since there are 105 women, and the ratio dictates that for every 7 women there are 4 men, we divide 105 by 7 to find the number of units that represent women, which is 15.

We then multiply this by 4 (the number of men) to find the number of men, which is 60.

105 + 60 = 165

The additive inverse is the idea of adding a negative number, which is the same as subtraction. Example: 2 + (-3) = 2-3

Based on the example above, if we start off with 3 and add on its additive inverse -3, then 3 + (-3) = 3-3 = 0. In general, x + (-x) = x-x = 0. So adding any number with its additive inverse gets you 0 every time.

2. E. [tex]m\angle BEF=140^{\circ}[/tex]

3. D. 4.3 in

4. D. 40.8 ft

Step-by-step explanation:

1. By Angle Addition Postulate,

[tex]m\angle KLM=m\angle KLV+m\angle VLM[/tex]

Since

[tex]m\angle KLV=34^{\circ}\\ \\m\angle KLM=14x+19\\ \\m\angle VLM=12x+7,[/tex]

then

[tex]14x+19=34+12x+7\\ \\14x-12x=34+7-19\\ \\2x=22\\ \\x=11[/tex]

2. By Angle Addition Postulate,

[tex]m\angle FED=m\angle DEB+m\angle BEF[/tex]

Since

[tex]m\angle FED=14x+8\\ \\m\angle DEB=22^{\circ}\\ \\m\angle BEF=13x-3,[/tex]

then

[tex]14x+8=22+13x-3\\ \\14x-13x=22-3-8\\ \\x=11[/tex]

Therefore,

[tex]m\angle BEF=(13\cdot 11-3)^{\circ}=(143-3)^{\circ}=140^{\circ}[/tex]

3. The area of trapezoid is

[tex]A_{trapezoid}=\text{Midsegment}\times \text{Height}[/tex]

From the diagram,

then

[tex]\text{Midsegment}=\dfrac{1.2+4.2}{2}=2.7\ in[/tex]

Since the area of trapezoid is [tex]11.6\ in^2,[/tex] then

[tex]11.6\ in^2 =2.7\ in\times \text{Height}\\ \\\text{Height}=\dfrac{11.6\ in^2}{2.7\ in}\approx 4.3\ in[/tex]

4. Use formula for the area of the circle to find the radius of the circle:

[tex]A_{circle}=\pi r^2[/tex]

So,

[tex]132.7=\pi r^2\\ \\r^2=\dfrac{132.7}{\pi}\\ \\r=\sqrt{\dfrac{132.7}{\pi}}\ ft[/tex]

Now, find the circumference of the circle:

[tex]C=2\pi r\\ \\C=2\pi \cdot \sqrt{\dfrac{132.7}{\pi}}=2\sqrt{132.7\pi}\approx 40.8\ ft[/tex]

The equations used to find the length of leg of triangle are:

[tex]0.5x(x+2) = 24\\\\x^2+2x-48=0\\\\x^2+(x+2)^2 = 100[/tex]

Solution:

From given,

Area of right triangle = 24 square feet

Also from given figure in question (attached below )

base = x and height = x + 2

The area of triangle is given by formula:

[tex]Area = \frac{1}{2} \times base \times height[/tex]

Substituting the values we get,

[tex]24 = \frac{1}{2} \times x \times (x+2)\\\\24 = 0.5x(x + 2)\\\\48 = x(x+2)\\\\x^2 + 2x - 48 = 0\\\\[/tex]

Also, the above equation can be written as,

[tex]x^2 + (x+2)^2 =100[/tex]

Thus the equations used to find the length of leg of triangle are:

Answer:

x= 14√3

y= 28√3

Step-by-step explanation:

Please see attached picture for full solution.

(tan30° and cos30° are special angles so there's an exact value to it in which we can memorise.)

In this case, by Pythagoras's Theorem, you should ensure that:

[tex] {y}^{2} = 42^{2} + {x}^{2} [/tex]

✓ Let's check:

[tex]{y}^{2} = (28 \sqrt{3} )^{2} \\ y^{2} = 2352 \\ {x}^{2} + {42}^{2} = ( 14\sqrt{3})^{2} + 1764 = 2352[/tex]

This satisfies Pythagoras' Theorem :)

For this kind of questions, first label the adjacent side, opposite side and the hypotenuse side of the triangle.

Cosine angle= adjacent/ hypotenuse

Sine angle= opposite/ hypotenuse

tangent angle= opposite/ adjacent

Then substitute the known side and angle to find the unknown side.

Answer:

6 cups

Step-by-step explanation:

did the math

For two cups of boiling water, 6 cups of sugar would be needed

The first step is to determine how many cups of sugar that would be needed for one cup of boiling water

The number of cups of sugar needed for a cup of boiling water = cups of sugar / cups of boiling water

2 ÷  [tex]\frac{2}{3}[/tex]

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

The second step is to determine the number of cups of sugar that would be needed with two cups of boiling water

Cups of sugar needed for 2 cups of water = cups of sugar needed for one cups of boiling water x 2

3 cups x 2 cups = 6 cups

In order to determine the cups of sugar needed for two cups of boiling water, first determine the number of cups of sugar needed for a cup of boiling water. Use the figure determined to find the cups of sugar needed for 2 cups of water
