<ABC + <CBD = <ABD
substitute <ABD = 85 and <CBD = x
<ABC + x = 85
R = √10
h = √40 = 2√10
lateral area = 2 pi r h = 2 pi √10 2√10 = 40 pi = 125.6 units^2
Y = mx + b....m is the slope and b is the y intercept
slope(m) = 5...(4,0)...x = 4 and y = 0
now we sub our info into y = mx + b...we r looking for b, the y intercept
0 = 5(4) + b
0 = 20 + b
-20 = b
so ur equation is y = 20x - 20...but we need it in standard form
Ax + By = C
y = 20x - 20....subtract 20x from both sides
-20x + y = -20...multiply by -1 to make x positive
20x - y = 20 <== standard form
9 and 1/2 is the answer. We can find this by simply subtract 1 1/2 from 12.
Step-by-step explanation:
commision = 7% of $9000
commision = 7/100 * $9000
commision = $630
