Your answer is B. (p + q) + r
This is because when doing addition, the order of the addition doesn't matter, as in both instances all of the terms are getting added together. I hope this helps!

A tank with capacity T gallons is empty. If water flows into the tank from pipe X at the rate of X gallons per minute, and water

Andrej [43]

A tank with capacity T gallons is empty. Tank will be filled in $\frac{t}{(x - y)}$ minutes

<u>Solution:</u>

Given, A tank with capacity T gallons is empty.

We have to find how many minutes will tank be filled?

Now, Water flows into the tank from pipe X at the rate of X gallons per minute,

And water is pumped out by pipe Y at the rate Y gallons per minute,

Then, together in one minute the amount of water filled will be x – y gallons [as X is greater than Y]

Now, the time take to fill tank = $=\frac{\text { capacity of tank }}{\text { amount of water filled per minute }}=\frac{t}{x-y}$

Hence tank will be filled in $\frac{t}{(x - y)}$ minutes

A group of friends were working on a student film. They spent all their budget on props and costumes. They spent $693 on props,

sergeinik [125]

Answer:

The total budget is $1260

Step-by-step explanation:

Given

$Props = \$693$

$Costumes = 45\%$

Required

Determine the total budget

Since all budgets was spent on Props and Costumes only.

We have that.

$\%Props + \%Costumes = 100\%$

$\%Props + 45\%= 100\%$

$\%Props= 100\% -45\%$

$\%Props= 55\%$

In other words, 55% was spent on Props

Let the total budget be x, we have:

$55\% * x = \$693$

Make x the subject

$x = \$693/55\%$

$x = \$1260$

Hence, the total budget is $1260
