Answer:
Slope = 0.06
37.44 would be the cost of the plane after 624 minutes.
Step-by-step explanation:
( x1, y1 ) = ( 100, 14 )
Here,
x1 = 100
y1 = 14
( x2, y2 ) = ( 200, 20 )
x2 = 200
y2 = 20
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( 20 - 14 ) / ( 200 - 100 )
= 6 / 100
x = 624 minutes
y = ?
Slope = y / x
y = Slope * x
= 0.06 x 624
y = 37.44
48 cm ²
area of a triangle is the base times the height and then then answer is divided by 2
bh/2
8 times 12 = 96/2 = 48 cm ²
