Answer:

That is 6 days are between each pickup

Step-by-step explanation:

The recycling facility picks up 120 full barrels on each trip, and each barrel holds 12 quarts of wastewater.

Volume of water carried by recycling facility = 12 x 120 = 1440 quarts.

Wastewater is filling barrels at the rate of 11 quarts per hour.

Number of hours required to fill 1440 quarts =\frac{1440}{11}=130.91\texttt{ hours}

Number of days=\frac{130.91}{24}=5.45\texttt{ days}

So, 5.45 days are between each pickup

That is 6 days are between each pickup

11t=120(12)

11t=1440

t=1440/11

However t is in hours and we want to know days so:

d=(1440/11)/24

d=1440/264

d=60/11

d=5 5/11 days

In A School Election 3/4 Of The Students Vote. There Are 1464 Ballots. Write And Solve An Equation To Find The Number Of Student
klasskru [66]
A simple way to turn this into an equation is by replacing the words with letters: 
1464B = 3/4 S

Then you have to remove the 3/4 from the right side of the equation.  You can do this by dividing both sides by 3/4: 
1464 / 3/4 = S

Then you have to do the sum: 
   1464 
 / 3
= 0488

     488 
     X  4
= 1952

There are 1952 students.

a week before election day, 276 out of 450 people said they would vote for the republican candidate. if 15,240 registered voters
Ann [662]

Answer:

(a) \frac {276}{450}=\frac {y}{15240}

(b) We cross multiply the probability by the total voters

(c) 9347

Step-by-step explanation:

(a)

Probability of getting a republican voter is

\frac {276}{450}=\frac {138}{225}=\frac {46}{75}

\frac {276}{450}=\frac {138}{225}=\frac {46}{75}=\frac {y}{15240}

These are found by dividing the first numerator and denominator by 2, then by 3

To make it complete, the situation is therefore defined as \frac {276}{450}=\frac {y}{15240} where y is unknown value

(b)

Cross multiplication of the probability and number of voters gives the actual figure of y in the equation formed in part a of the question.

(c)

Since we have 15240 voters who plan to participate in election, we cross multiply to get the approximate number of republican voters which yields

\frac {46}{75}\times 15240=9347.2\approx 9347
