Can someone help me I need to know the unit rate of:
sladkih [1.3K]

Answer:

A. 60 miles per hour

B.120 customers per day

C.2.5 meters per second

D. $1.59  per pound

Step-by-step explanation:

Here we are asked to determine the unit rate for each one of the options given. By unit rate we mean the quantity for per unit quantity . Hence in order to find that we divide the two and quotient is our unit rate. Let us see how:

A. 420 miles in 7 hours

Unit rate = \frac{420}{7}

Unit rate = 60 miles per hour

B. 360 customers in 30 days

unit rate = \frac{360}{30}

Unit rate = 120 customers per day

C. 40 meters in 16 seconds

Unit rate = \frac{40}{16}

Unit rate = 2.5 meters per second

D. $7.96 for 5 pounds

Unit rate = \frac{7.96}{5}

Unit rate = $1.59  per pound

Plisss help write the linear equation that vives the rule for this table ​
sineoko [7]

well, we know is a line,  and to get the equation of any straight line all we need is two points, hmmm let's use from the table hmm say (2 , -50) and hmmm (4 , -88)

(\stackrel{x_1}{2}~,~\stackrel{y_1}{-50})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-88}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-88}-\stackrel{y1}{(-50)}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}}\implies \cfrac{-88+50}{2}\implies \cfrac{-38}{2}\implies -19

\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-50)}=\stackrel{m}{-19}(x-\stackrel{x_1}{2}) \\\\\\ y+50=-19x+38\implies y=-19x-12
