Conclusion:
Please refer to the explanation provided.
Detailed explanation:
Starting with these facts:
Total revenue = $250
Fee charged = $70 per car
Tips received = $50
Equation 1 representing the above:
(Fee per car × number of cars) + tips = total revenue
Let the number of cars be c.
Thus, we have:
$70c + $50 = $250
Part B:
Total revenue = $250
Fee charged = $75 per car
Tips received = $35
Supplies cost per car washed = $5
Equation 2:
(Fee per car × number of cars) + tips - (supplies cost × number of cars) = total revenue
$75c + $35 - $5c = $250
$70c + $35 = $250
Part C:
Equation 1 does not factor in costs associated with washing the car, while equation 2 does incorporate costs, which are deducted from the amount charged per car. Additionally, tips in equation 1 total $50 compared to a $35 fee in equation 2.
Answer:
3/10 liter
Step-by-step explanation:
Assuming your statement indicates that in 4/3 liters of punch, there is 2/5 liters of water, then the proportion of water in the punch is calculated as:
(2/5)/(4/3) = (2/5)(3/4) = 3/10
So, 3/10 of a liter of water is included in each liter of punch.
It can be deduced that because line JL serves as a diameter for a circle, lines JK and KL function as the tangents of that circle. A tangent is defined as "a line that touches a curve at a singular point without intersecting it." Thus, both lines contact the perimeter of circle M, confirming they are tangents.
