Zanzabum

Answer:

187.06 units²

Step-by-step explanation:

Area of kite:

½ × d1 × d2

½d1 = 18sin(30)

½d1 = 9

d1 = 18

d2 = 9/tan(60) + 18cos(30)

= 12sqrt(3)

Area = ½ × 18 × 12sqrt(3)

108sqrt(3) units²

1 pizza costs £3.20 more than a bottle of coke. The total cost of the items is £19.40 for 3 pizzas and 1 bottle of coke
Korolek [52]

1 pizza should cost $5.65

Pizza is $5.65 then bottle of coke is $2.45

3 pizzas and coke: ($5.65*3) + $2.45 = $19.4

I solved this by setting up and solving a system of linear equations:

Variables: p = pizza, c = coke

p = c+3.2

3p+c = 19.4

Solve by substitution

3(c+3.2) + c = 19.4

4c+9.6 = 19.4

c = 2.45

Re-plug in:

p = 2.45+3.2

p = 5.65
