Answer:

<h2>x = 10.3</h2>

Step-by-step explanation:

Use sine.

sine=\dfrac{opposite}{hypotenuse}

We have:

opposite=x\\hypotenuse=16

\sin40^o\approx0.6428        <em>look at the table in the picture</em>

Substitute:

\dfrac{x}{16}=0.6428         <em>multiply both sides by 16</em>

x=10.2848\to x\approx10.3

After the game the coach bought 9 chicken meals for 5 dollars each and 15 burger meals for 6 dollars each. What percent of the t
svetoff [14.1K]
1 chicken meal = $5
9 chicken meals = 9($5)= $45
-
1 burger meal = $6
15 burger meals = 15($6) = $90
-
Total amount = $90+$45 = $135
-
Percent spent on chicken meals = [$40 ÷ $135] x 100
                                                       = 0.296 x 100
                                                        = 29.6% or approximately 30%

(5, 3) and (8, -2) Write the standard form of the equation of the line that passes through the given points.
Lerok [7]
Slope = (y2 - y1) / (x2 - x1)
(5,3)...x1 = 5 and y1 = 3
(8,-2)..x2 = 8 and y2 = -2
now we sub
slope = (-2 - 3) / (8 - 5) = -5 / 3

y = mx + b
slope(m) = -5/3
use either of ur points..(5,3)...x = 5 and y = 3
now we sub and find b, the y int
3 = -5/3(5) + b
3 = -25/3 + b
3 + 25/3 = b
9/3 + 25/3 = b
34/3 = b

ur equation is y = -5/3x + 34/3...but we need it in standard form

y = -5/3x + 34/3
5/3x + y = 34/3
5x + 3y = 34 <=== standard form
