Answer:60 %

Step-by-step explanation:

<h3>if we set up an proportion, $\frac{20}{100}$ = $\frac{12}{x}$ the answer is 60. </h3><h3>100x12=1200</h3><h3>1200 divded by 20 =60</h3>

PLEASE HELP I WILL MARK!!

Rina8888 [55]

answer is D

Explamation:

given points are (7,9) and (12,11)

$mid \: point \: of \: x = \frac{x1 + x2}{2 } = \frac{7 + 12}{2} = 9.5 \\ midpoint \: of \: y = \frac{y1 + y2}{2} = \frac{9 + 11}{ 2} = 10$

therefore the mid point is (9.5,10)

The monthly charge for a waste collection service is 1830 dollars for 100 kg of waste and 2460 dollars for 135 kg of waste. (a)

Ulleksa [173]

Answer:

$C=18w+30$

Step-by-step explanation:

We are given that The monthly charge for a waste collection service is 1830 dollars for 100 kg of waste

So, $(x_1,y_1)=(100,1830)$

We are also given that The monthly charge for a waste collection service is 2460 dollars for 135 kg of waste.

So, $(x_2,y_2)=(135,2460)$

We are supposed to find a linear model for the cost, C, of waste collection as a function of the number of kilograms, w.

So, we will use two point slope form :

Formula : $y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Substitute the values

$y-1830=\frac{2460-1830}{135-100}(x-100)$

$y-1830=18(x-100)$

$y-1830=18x-1800$

$y=18x-1800+1830$

$y=18x+30$

y denotes the cost

x denotes the weight

So, Replace y with C and x with w

$C=18w+30$

So, a linear model for the cost, C, of waste collection as a function of the number of kilograms, w is $C=18w+30$

The graph that represents the function is graph b. Graph b is the only graph the appropriately represents the y intercept (the value of y when x = 0).
