The length of the base edge of a pyramid with a regular hexagon base is represented as x. The height of the pyramid is 3 times l

sergij07 [2.7K]

Answer:

(a)

h=3x

(b)

$A=\frac{\sqrt{3} }{4} x^2$

(c)

$A=\frac{3\sqrt{3} }{2} x^2$

(d)

$V=\frac{3\sqrt{3} }{2} x^3$ units^3

Step-by-step explanation:

We are given a regular hexagon pyramid

Since, it is regular hexagon

so, value of edge of all sides must be same

The length of the base edge of a pyramid with a regular hexagon base is represented as x

so, edge of base =x

b=x

Let's assume each blank spaces as a , b , c, d

we will find value for each spaces

(a)

The height of the pyramid is 3 times longer than the base edge

so, height =3*edge of base

height=3x

h=3x

(b)

Since, it is in units^2

so, it is given to find area

we know that

area of equilateral triangle is

$=\frac{\sqrt{3} }{4} b^2$

h=3x

b=x

now, we can plug values

$A=\frac{\sqrt{3} }{4} x^2$

(c)

we know that

there are six such triangles in the base of hexagon

So,

Area of base of hexagon = 6* (area of triangle)

Area of base of hexagon is

$=6\times \frac{\sqrt{3} }{4} x^2$

$=\frac{3\sqrt{3} }{2} x^2$

(d)

Volume=(1/3)* (Area of hexagon)*(height of pyramid)

now, we can plug values

Volume is

$=\frac{1}{3}\times\frac{3\sqrt{3} }{2} x^2\times (3x)$

$V=\frac{3\sqrt{3} }{2} x^3$ units^3

Plz help brainiest to the correct answer!

Stolb23 [73]

Answer:

1. x (multiplication)

2. / (division)

3. - (subtraction)

4. - (subtraction)

5. / (division)

Step-by-step explanation:

1. 24 x 3/4= 18

2. 24/-3/4=-32

3. 12- 15= -3

4. 12- (-15)= 12 + 15 = 27

5. -18 / -3/4= 24

Jodie wanted to match Mandy's obstacle course record of 73.4 seconds. She had already spent seconds on wall climbing and 11.78 s

Artyom0805 [142]

The time left to match the record will be 61.62 seconds. The correct option is A.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Jodie wanted to match Mandy's obstacle course record of 73.4 seconds. She had already spent seconds on wall climbing and 11.78 seconds on the ropes.

The time left to match the record will be calculated as below:-

Time left = 73.4 - 11.78 = 61.62

Therefore, the time left to match the record will be 61.62 seconds. The correct option is A.
