Answer:

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, 
We are also given that The monthly charge for a waste collection service is 2460 dollars for 135 kg of waste.
So, 
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 : 
Substitute the values





y denotes the cost
x denotes the weight
So, Replace y with C and x with w

So, a linear model for the cost, C, of waste collection as a function of the number of kilograms, w is 
Assume Charles charges $7*3=$21 if he babysits for 2,5 hours (that is 2 and a half hours).
That is we are not considering Charles babysitting exactly 1, 2, 3 or 4 hours, but also in between times.
then we can write the following piecewise function to describe the situation:
f is a function from (0, 4] to {$7, $14, $21, $28}
Answer:
1.5 pints per sundae
Step-by-step explanation:
To solve the questions,we can first divide 23 by 4:
23÷4
=5..3
As we divide 23 by 4, there would be 3 strawberries left which cannot be counted as a bowl with 4 exactly strawberries.
Therefore the answer is 5.
Hope it helps!
Answer:
0.27433628318584
Step-by-step explanation:
To write 31/113 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 31 by 113 what we write down as 31/113 and we get 0.27433628318584
And finally we have:
31/113 as a decimal equals 0.27433628318584
