Find the value of each variable:

Leona [35]

Answer:

5√3 = b

5 = d

10√3 = a

15 = c

Step-by-step explanation:

Sin60° = opp/hyp

sin60° = b/10

10sin60° = b

5√3 = b

Cos60° = adj/hyp

Cos60° = d/10

10Cos60° = d

5 = d

Sin30° = opp/hyp

Sin30° = 5√3/a

a = 5√3/Sin30°

a = 10√3

Tan30° = opp/adj

Tan30° = 5√3/c

c = 5√3/tan30°

c = 15

Gina wants to take dance classes. She compares two dance studios to determine which has the best deal for her. Dance World charg

fomenos

Answer:

10 classes

Step-by-step explanation:

Given equations in the question

Dance World: y = 15x

Toe Tappers: y = 25 + 12.5x

Where,

x = number of classes

Equate the total cost at both dance studios

15x = 25 + 12.5x

Collect like terms

15x - 12.5x = 25

2.5x = 25

Divide both sides by 2.5

2.5x / 2.5 = 25 / 2.5

x = 10 classes

x = number of classes = 10

A square pyramid has base edge length 14 m. The height of the pyramid is 24 m. Find the surface area of the square pyramid. Use

kotegsom [21]

Answer:

The total surface area is 896 $m^{2}$

Step-by-step explanation:

<em>The square pyramid is a solid with square base and symmetric 4 triangular faces.</em>

Given that the square base is 14 m and height is 24 m.

The apex of pyramid, center of square and center of any edge of square make a right angled triangle.

Let that height if triangular face be "x".

by pythagoras theorm , $x^{2} = 7^{2} + 24^{2} = 625$

x = 25 m

the area of square base is $14^{2} = 196 m^{2}$

the area of each triangular side is <em> $(\frac{1}{2})(base)(height) = (\frac{1}{2})(14)(25) = 135 m^{2}$ </em>

such are 4 triangles, thus $(4)(135) = 700 m^{2}$

Thus the total surface area is 196 + 700 = 896 $m^{2}$
