Answer: 262.5 gallons were used.
Explanation:
First find 1/4 of 350 by multiplying .25 by350 (.25 is 1/4 in decimal form)
In doing that, you get 87.5
Then all you have to do is subtract 87.5 from 350 and you get your answer

At noon, the minute and the hour hands of a clock overlap. In how long will they again overlap?
kati45 [8]

Answer:

Okay. At noon, the hour and minute hand overlap. First, let’s calculate the speed of the hands.

The minute hand rotates once around the clock every hour. It goes 360 degrees in 60 minutes, so it rotates 360/60 or 6 degrees per minute. The hour hand goes once around the clock every 12 hours. Because there are 60 minutes in an hour, it goes 360 degrees 12*60 or 720 minutes. This means it travels at a speed of 360/720 or 0.5 degrees per minute.

Once the clock starts, the minute hand goes ahead and rotates ahead of the hour hand. At 1:00, the minute hand is at 12, and the hour hand is ahead at 1. This is where we will start our calculations.

Now, we have a variable, m, which is the minutes that have passed since the clock started. So, our minute hand speed is 6m, and our hour hand speed is 0.5m. However, because the hour hand is at one, it is at 30 degrees. (360/12 * 1.) This means our equation is 6m = 0.5m+30.

Now, we calculate.

6m = 0.5m+30

5.5m = 30

m = 30/5.5

m = 5.45

So at 5.45 minutes, the minute hand is at the hour hand. However, because one hour has passed since we started, we have to add on one hour.

So, our final total is 1 hour 5 minutes and 27 seconds.

What's the correct answer
ratelena [41]
The answer is A, the equation shows a proportional relationship because the graph shows a straight line. However, it is not DIRECTLY proportional as it does not pass through the origin.

Find the GCF of each expression. Then factor the expression.
GaryK [48]
For finding GCF, just find the least number among them.
For example: 
a.) 6x^2 - 9 find what number that can be divided to 6. In this case, it is 2 and 3. 
You can't divide 9 by 2 so the answer in this equation would be 3.

b.) 2a^ 2 + 22a + 60 I's just the same method to use. In this case, we will use 2a^2. The factors that can be divided to 2 is (2,1). So we will choose 2 because it is the GCF of 2 and the equation is divisible by 2.

Solve the proportion. a. 4/x = 9 b. 7.5/26 = 75/p
lina2011 [118]

<u>ANSWER: </u>

The values of x and p after solving given equations are 0.445 or \frac{4}{9} and 260 respectively..

<u>SOLUTION: </u>

Given, two proportions are \frac{4}{x} =9 and \frac{7.5}{26} = \frac{75}{p}

We need to solve the given two proportions.

Let us solve the first proportion, \frac{4}{x} = 9

\frac{4}{x} = \frac{9}{1}

On cross-multiplication, we get

4 \times 1 = 9x

4 = 9x

x = \frac{4}{9}

x = 0.445

Now, let us solve the second proportion  \frac{7.5}{26} = \frac{75}{p}

\frac{\frac{75}{10}}{26}=\frac{75}{p}

\frac{75}{10 \times 26} = \frac{75}{p}

\frac{1}{260} = \frac{1}{p}

On cross-multiplication, we get

p = 260

Hence, the values of x and p after solving given equations are 0.445 and 260 respectively.
