What is the value of x?
2x + 6 = 18

Answer:

She can buy 8 bags of soil

Step-by-step explanation:

2.7s + 14.9 < 39.2

Subtract 14.9 from both sides

2.7s  < 39.2 - 14.9

2.7s < 24.3

Divide both sides by 2.7

s < 24.3 /2.7

s < 8.89

The Surface area of hexagonal pyramid= 358.32 cm square

Formula of surface area of hexagonal pyramid= 3ab+3bs
where a = apothem of pyramid
            b= base
            s= slant height
here a= 6.93cm
         b= 8cm
         s= 8cm*
* a^2 + b/2 ^2 = s^2
  6.93^2 + 4^2 = 8
Area = 3*6.93*8+ 3*8*8= 358.32

The surface area of the hexagonal pyramid is,

⇒ Surface Area of Hexagonal Pyramid = 478.32 square units

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

In the diagram of the base of the hexagonal pyramid, all the triangles are the same.

Here, The slant height of the pyramid (s) = 13 cm

And, Base (b) = 8 cm

And, Apothem (a) = 6.93 cm

Now, We know that;

The surface area of the hexagonal pyramid is,

⇒ Surface Area of Hexagonal Pyramid = (3ab + 3bs) square units

After putting the values we get;

⇒ Surface Area of Hexagonal Pyramid = (3 × 6.93 × 8 + 3 × 8 × 13) square units

⇒ Surface Area of Hexagonal Pyramid = 478.32 square units

Thus, The surface area of the hexagonal pyramid is,

⇒ Surface Area of Hexagonal Pyramid = 478.32 square units

Answer:

The answer is B

Step-by-step explanation: The pythagorean theorem is in a right triangle, the sum of squares of 2 sides of right angle equals the square of hypotenuse. So [tex]6x^{2} +8x^{2}[/tex]= 36+64=100

And the [tex]\sqrt{ 100[/tex] equals 10 so B is the answer

Answer:

you find a slope by looking at which way the line is going

Step-by-step explanation:

You have to look from left to right to find a slope. if the slope is going downwards, it is negative. if it is going up, its positive. ( I don't know the answer to number 2 sorry)

Answer:

Diameter: 14

Radius: 7

Step-by-step explanation:

To find the diameter, you do 43.96 divided by 3.14 and that equals 14

To find the radius, you just divide 14 by 2 and that equals 7.

If the height was 12 the answer would be 10,944 but if the height was 18 the answer would be 16,416. Hope this helps.

90 Yan na haaaàaaaaa

A=_m2=90

Answer:

its 100

Step-by-step explanation:

well since its a parallel line, 7 and 3 are corresponding and that makes 3 also 80. buh then 3 is also adjacent to 2 and that makes it also 80 and since 2 is on the same line as 1 and an angle on a straight line is 180, it automatically makes 1 an angle of 100 as 180 - 80 should give u 100.

Answer:

the answer is C (280 square feet)

Step-by-step explanation:

First, cut the lawn so that it becomes two shapes: a rectangle, and a triangle. Solve for both areas.

A(r) = lw

A(r) = (14)(16)

A(r) = 224 square feet

A(t) = bh/2

A(t) = (8)(14) / 2

A(t) = 112 / 2

A(t) = 56 square feet

Add the two areas:

A(r) + A(t) = Area of lawn

224 square feet + 56 square feet = 280 square feet.
