Answer:

x=6

Step-by-step explanation:

Kindly look at the image provided below.

The image shows the relationship between intersecting secants and their corresponding arcs which is important to understand when looking at problems like these.

The relationship states that an angle formed by two intersecting secants is equal to half the sum of its corresponding arc and its vertical angles corresponding arc.

So ∠FHG = 1/2 ( arc FG + arc EB )

* substitute the given expressions for each angle and arc *

we would then have

15x - 2 = 1/2 ( -2 + 12x + 16x + 10 )

We now solve for x

Step 1 multiply each side by 2

1/2 ( -2 + 12x + 16x + 10 ) *2  = ( the 2 and 1/2 cancels out )  -2 + 12x + 16x + 10

(15x - 2 )2 = 30x - 4

we now have -2 + 12x + 16x + 10 = 30x - 4

step 2 combine like terms

-2 + 10 = 8

12x + 16x = 28x

now we have 30x - 4  = 28x + 8

step 3 add 4 to each side

-4 + 4 cancels out

8 + 4 = 12

Now we have 30x = 28x + 12

step 4 subtract 28x from each side

30x - 28x = 2x

28x - 28x cancels out

now we have 2x = 12

step 5 divide each side by 2

2x / 2 = x

12 / 2 = 6

we're left with x = 6

Answer:

A. 11.25

Step-by-step explanation:

If point C(x, y) divides line segment AB with end points at A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2\\[/tex]) in the ratio on n:m, then the coordinates of point C is:

[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]

Given that segment AB is divided by point C in the ratio of 3:1. Given A(3, 12) and B (14, 17). Let coordinate of C be (x, y), hence:

[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1\\\\x=\frac{3}{3+1}(14-3)+3=\frac{3}{4}(11)+3=11.25 \\\\\\y=\frac{n}{n+m}(y_2-y_1)+y_1\\\\y=\frac{3}{3+1}(17-12)+12=\frac{3}{4}(5)+12=15.75[/tex]

Therefore, the coordinate of point C = (11.25, 15.75)

The x coordinate of point C is 11.25

Answer:

D

Step-by-step explanation:

The horizontal cross-sections of the prisms which is at same height as the cone should have same area.

Therefore Option D is the answer.

A cone is a three dimensional figure that has a circular horizontal structure ,  and vertically tapering up till a point.

It is given that

A Pyramid and a cone both have same volume.

Height of cone is same as Height of Pyramid .

Volume of cone = (1/3)πr²h

Volume of a pyramid =  Area of base * h

When both the volume are equated

as height is same

The Area of the base of the cone =  Area of the base of the Pyramid

The horizontal cross-sections of the pyramid which is at same height as the cone should have same area.

Therefore Option D is the answer.

Answer:

6

Step-by-step explanation:

Answer:

72 square units

Step-by-step explanation:

you can use the Pythagorean Theorem; because we're dealing with a square then each side can be assigned the same variable, let's use 'a'

a² + a² = 12²

2a² = 144

a² = 72

a = [tex]\sqrt{72}[/tex]

[tex]\sqrt{72}[/tex] can be simplied as [tex]\sqrt{9}[/tex]·[tex]\sqrt{4}[/tex]·[tex]\sqrt{2}[/tex] which is 3·2·[tex]\sqrt{2}[/tex]

each side has a length of 6[tex]\sqrt{2}[/tex]

A = (6[tex]\sqrt{2}[/tex])² which is 6·6·2 or 72

Answer:

1/45 acres the farmer planted

starting with 2 cubes that have 6 numbers total for each one, so 2 cubes will have 12 numbers total, and the probability of number 5 is 2/12 (because each cube has a number 5, so two cubes will have 2, and fraction for it will be 2/12).

The probability the sum total will be 5 is 4/36.

"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one".

For the given situation,

The sample space for rolling two 6 sided cube is

s ={

    [tex](1,1), (1,2), (1,3), (1,4), (1,5), (1,6)\\(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)\\(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)\\(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)\\(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)\\(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)[/tex] }

⇒ [tex]n(s)=36[/tex]

The event is getting the probability that the sum total will be 5.

e = { [tex](1,4), (2,3), (3,2), (4,1)[/tex] }

⇒ [tex]n(e)=4[/tex]

Thus the probability that the sum total will be 5 is

[tex]P(e)=\frac{n(e)}{n(s)} \\[/tex]

⇒ [tex]P(e)=\frac{4}{36}[/tex]

Hence we can conclude that the probability the sum total will be 5 is 4/36.

Answer:

You can use the time value of money formula.

FV = PV(1 + r)^n

FV = future value

PV = present value

r = interest rate = percentage/100

n = number of compounding periods

FV = 500*(1 + 0.075)^10 = $ 1030.52

Answer:

-4, -2, 6, 10, 12

Step-by-step explanation:

The function is h(x) = 2x + 4. H(x) is basically just another way of writing "y", so we technically have y = 2x + 4. We can complete the table by substituting the value of x that the table gives us.

The table gives us x = -4 and wants us to find h(x), or y. So, we do y = 2(-4) + 4 and we get y = -4.

The table gives us x = -3 so we do y = 2(-3) + 4 and we get y = -2.

The table gives us x = 1 so we do y = 2(1) + 4 and we get y = 6.

The table gives us x = 3 so we do y = 2(3) + 4 and we get y = 10.

The table gives us x = 4 so we do y = 2(4) + 4 and we get y = 12.
