Answer:

Step-by-step explanation:

The equation of a proportional relationship is

y = kx ← k is the constant of proportionality

Divide both sides by x

$\frac{y}{x}$ = k

To find k use any ordered pair from the table

Using (2, $\frac{5}{2}$ ) , then

k = $\frac{2}{\frac{5}{2} }$ = 2 × $\frac{2}{5}$ = $\frac{4}{5}$

I need this problem solved real quick

PIT_PIT [208]

Let's take this problem step-by-step:

The ;unlabeled angle' adjacent to the 'outside angle of measure 78°'

⇒ is on a straight line

⇒ sum of angle measure = 180 degrees

$unlabeled_.angle+78 = 180\\unlabeled_.angle = 102$

Now we know:

⇒ sum of all angles in a triangle ⇒ 180°

Let's put that in equation form and solve:

$x + 102 + 57=180\\x + 159=180\\x = 21$

Answer: 21°

Hope that helps!

Find the unit rate. 80 rooms on 5 floors = = rooms per floor Submit

Ganezh [65]

<h3>The formula to find unit rate is:</h3>

divide the denominator with the numerator in a way that the denominator becomes 1

$\begin{gathered}\\ \sf\longmapsto \frac{80}{5}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto\cancel{\dfrac{80}{5}} \end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 16\end{gathered}$

Hence, The unit rate is 16 rooms per floor.
