Answer:

Step-by-step Explanation:
Given:
∆WXY
m < X = 130°
WY = x = 31 mm
m < Y = 26°
Required:
Area of ∆WXY
Solution:
Find the length of XY using Law of Sines

X = 130°
x = WY = 31 mm
W = 180 - (130 + 26) = 24°
w = XY = ?

Multiply both sides by sin(24) to solve for x


(approximated)

Find the area of ∆WXY



(to nearest tenth).
Suppose that the height (in centimeters) of a candle is a linear function of
the amount of time (in hours) it has been burning.
Let x be the amount of time in hours
Let y be the heoght of a candle in centimeters
The two points are then as (9,24.5) and (23,17.5).














Now plug in x=21, we get

Thus the height of the candle after 21 hours is 18.5 centimeters.
Answer:
x=6
Step-by-step explanation:
x+3=9
x+3-3=9-3
x=6
(a) 28%
(b) 24%
When calculating the total amount of people it come out to 150.
According to the table 42 people smoke. 42/150 is 28%
According to the table 36 people exercise regularly. 36/150 is 24%
