A leaky valve on the water meter overcharges the residents for one gallon of water every 1 1 over 3 months. The overcharged amou

nt w varies directly with time t. Find the equation that models this direct variation. How many months it will take for the residents to be overcharged for 5 gallons of water? A) w = 3 over 4t; 62 over 3 months.B) w = 4 over 3t; 62 over 3 months. C) w = 3 over 4t; 33 over 4 months. D) w = 4 over 3t; 33 over 4 months

The number of months overcharged for 1 gallon of leaky water = 1 1/3
                                                                                                     = 4/3
Let us assume the quantity of water overcharged = w
Let us assume the time in months = t
Then, the equation modelling this direct variation is
w = (3/4)t
When w = 5, then
5 = (3/4) * t
20 = 3t
t = 20/3
  = 6 2/3
From the above deduction, we can conclude that the first option or option "A" is the correct option. I hope the answer helps you.

The correct answer to this question is letter "<span> A) w = 3 over 4t."
</span>Given that the  number of months overcharged for 1 gallon of leaky water is equal to 1 1/3 and which is equal to 4/3.

Let w the quantity of water overcharged
Let t  the time in months

Let's make the equation. We have to use direct variation.
w = (3/4)t

w = 5, we will be able to get t
5 = (3/4) * t
20 = 3t
t = 20/3 = 6 2/3

Can anyone help me in Ptolemy's theorem?
GalinKa [24]

Answer:

Well, I'm not sure what you mean but Ptolemy's Theorem gives a relationship between the side lengths and the diagonals of a cyclic quadrilateral; it is the equality case of Ptolemy's Inequality. Ptolemy's Theorem frequently shows up as an intermediate step in problems involving inscribed figures.

BlackZzzverrR [31]
Hey! If 27 cars make up 60%, divide that by 6 to get 10% of the answer which is 4.5. Multiply 4.5 by 10 to get 100% which is 45 cars for 100%.

B. The school prom committee sold presale tickets for
Ivan

Answer:

218 students purchased tickets at the dance.

Step-by-step explanation:

Let,

x be the number of presale tickets

y be the number of tickets sold at the dance

According to given statement;

x+y=334      Eqn 1

18x+24y=7320    Eqn 2

Multiplying Eqn 1 by 18

18(x+y=334)

18x+18y=6012      Eqn 3

Subtracting Eqn 3 from Eqn 2

(18x+24y)-(18x+18y)=7320-6012

18x+24y-18x-18y=1308

6y=1308

\frac{6y}{6}=\frac{1308}{6}\\y=218

Therefore,

218 students purchased tickets at the dance.
