<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 \frac{1}{30} cm.

The angle of inclination,

tan(θ) = \frac{1}{30}

θ = 1.9º

By trignometric ratio,

cos(θ) = \frac{horizontal distance}{length of the drainpipe}

length of the drainpipe = \frac{700}{cos(1.91)} = \frac{700}{0.999}

length of the drainpipe = 700.7 cm

lindsay bedford works at the baseball cap shop. she is paid $6.50 per hour plus $0.45 for each cap she embroiders. how many caps
crimeas [40]

15 caps are needed so that she can earn $85 in an 8hour day.

<h3>How is the direct equation calculated?</h3>

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.)
