Answers

Answer:

Step-by-step explanation:

Answer:

(2/5)√5

Step-by-step explanation:

from the sine rule (see attached for reference), we can construct the following relationship

12/sinθ = (6√5) / sin 90°

recall that sin 90° = 1, hence our equation becomes:

12/sinθ = (6√5) / 1

12/sinθ = (6√5) (rearranging)

12 ÷ (6√5) = sin θ

sin θ = 12 / (6√5)

sin θ = 2 / √5 (moving radical to numerator by multiplying by √5/√5)

= 2 / √5 x √5/√5

= 2√5 / 5

= (2/5)√5

area = 2106

perimeter = 210

Step-by-step explanation:

area = length x width

(for this specific problem and since the shape is a rectangle)

perimeter = length + length + width + width

Answer:

A = 2106 yd^2 P = 210 yd

Step-by-step explanation:

PART A:

A = l x w

A = 78 x 27 = 2106 yd^2

P = l + w + l + w = 78 + 27 + 78 + 27 = 210 yd

find the value of the ratio (red to blue) of the areas of the similar figures. Write the ratio as a fraction in simplest form.

Answers

Answer:

16/225

Step-by-step explanation:

Ratio of the area of similar figures = ratio of the square of any of their corresponding side lengths

Thus:

Area of red triangle : area of blue triangle = square of side length of red triangle : square of side length of blue triangle

Area of red : area of blue = 4²/15²

= 16/225

3x + 1/3y=12
2y=18x+72

Show all work

A no solution
B one solution
C infinity solutions

Answers

Answer:

B one solution

Step-by-step explanation:

3x + 1/3y=12

2y=18x+72; y = 18x/2 +72/2; y =9x+36

3x + 1/3y=12

multiply all through by 3

9x + y = 36

9x + 9x+36 = 36

18x =36-36= 0

x= 0/18 = 0

y =9x+36

y = 9(0) +36 = 0+36= 36
