Answer:

<u>Proportional relationship formula:</u>

y = kx, where k is the constant of proportionality

Use one of the ordered pairs to calculate the value of k

<h3>Company A</h3>

Point (2, 20)

20 = k*2
h = 20/2
k = 10

The equation: y = 10h

<h3>Company B</h3>

Point (3, 20)

20 = k*3
k = 20/3
The equation: y = 20/3h

Company A has greater unit rate as 10 > 20/3

Find the value of x to the nearest tenth

Salsk061 [2.6K]

Answer:

x = 41.2

Step-by-step explanation:

Assuming the dotted line at the top is parallel to the segment with length x, it follows from the alternate interior angles theorem that the interior angle of the triangle (marked in diagram) is also 27º.

Using SOH-CAH-TOA, we get that tan(27º) = 21/x, so x = 21/tan(27º), which is approximately equal to 41.2.
