A builder makes drainpipes that drop 1 cm over a horizontal distance of 30cm to prevent clogs a certain drainpipe needs to cover
2 answers:
<h2>Answer:</h2><h2>Length of the drainpipe = 700.7 cm</h2>
Step-by-step explanation:
Given a builder makes drainpipes that drop 1 cm over a horizontal distance of 30cm to prevent clogs. The ratio of the vertical drop to the horizontal distance covered is cm.
The angle of inclination,
tan(θ) =
θ = 1.9º
By trignometric ratio,
cos(θ) =
length of the drainpipe = =
length of the drainpipe = 700.7 cm

15 caps are needed so that she can earn $85 in an hour day.
The direct variation equation has the form y = kx, where k is the constant proportionality. It is a linear equation with two variables. In a coordinate plane, the direct variation graph is a straight line. A constant is the ratio of two quantities that vary directly. Relationship between two variables that can be described mathematically by an equation where one variable equals a constant multiplied by the other.
For each hour she is compensated $6.50 with $0.45.
For an 8 hour day =6.50 *8 + 0.45x
Let x be the caps and earning is $85
6.50*8+0.45*x=85
=> 52+0.45x=85
=> 0.45x=33
=> x=15 (approx.)
