A crack in a water main pipe leaks 7 gallons of water each hour. What volume of water has moved though the crack after 9 hours?

Answers

Answer 1

63 gallons of water. y=7h
7=7(9)

Answer 2

So if we know that 7 gallons of water goes through the pipe every hour, and we want to find how much water goes through the pipe after 9, we want to say,

7 gallons of water 9 times because there are 9 hours.

7 gallons of water 9 times is basically 7 * 9, or 63.

So 63 gallons of water has moved through the crack after 9 hours.

Hello! Expanded form is when you write an addition problem by place value in order to get the sum for the answer. For example, expanded form of 123 is 100 + 20 + 3. In this case, 92.3 is out number we are going to expand in addition form. 92.3 in expanded form is 90 + 2 + 0.3. This is because 9 in the tens place has a value of 90, the 2 in the ones place has a value of 2, and the value of 3 in the tenths place has a value of 0.3.

Note: this answer was made with the assumption that you meant 5 1 2 as 5 1/2 / 5.5, though you may correct me if that is the wrong interpretation.

It will only take the company about 60 seconds, or a minute to take all 330 samples, for 330/5.5 = 60.

How do you write the equation?

Answers

The number of hours she practices each day is unknown, so let's call it x.

She practices dancing x hours each day she goes to practice.
Since she practices 3 days per week, in a week she practices 3x hours.
In two weeks she practices 2(3x) hours, or 6x hours.

We are told she practices 12 hours in 2 weeks, so 6x must equal 12.

The equation is

6x = 12

We can solve it by dividing both sides by 6.

x = 2

She practices 2 hours per day.

Check:
2 hours per for 3 days = 2 * 3 hours = 6 hours in 1 week.
In 2 weeks, she practices 2 * 6 hours = 12 hours.
Our solution is correct.

math question down below

Answers

for the first drain the equation you need would be: 2n = 108

for drain B your equation would be: 5n = 108

these are your equations because a number times the amount of water the drain drains per minute will equal 108

to solve use inverse operations and divide 108 by the amount of water the drain drains in one minutes

Drain A- 108/2 = 54
it takes 54 minutes for drain a to empty a pool with 108 gallons of water

Drain B- 108/5 = 21.6
it takes 21.6 minutes for drain b to empty a pool with 108 gallons of water in it

Graph y= 12x–3 .
Where would I put the points ?

Answers

We need to graph y = 1/2x - 3.
y = 1/2x - 3 is from the general form of a linear function y = ax + b, in which a represents the slope, b the y-intercept, and x and y the coordinates of 2 points.
Since it's a linear function, the graphical representation of that equation is a straight line.

To graph that function, we need at least 2 points from that line. And we'll find their coordinates using the equation.

1- For x = 0, y = -3 (Since the y-intercept is b = -3).
2- For x = 2. y = 1/2x - 3 = 1/2*2 - 3 = -2

So we now have the 2 points A (0, -3) and B (2, -2).Place those points on the graph, and reunite them with a line and you'll get your graphical representation of the linear function y = 1/2x - 3 (You can see the graphical representation in the image alongside my answer).

How to convert 18 gallons/1 hour to cups and minutes

Answers

so there are 2 things you need to convert, the first is the gallons to cups and the second is the hours to minutes. so I like to set it up with numerators and denominators and then multiply the ratios. All same terms will cross out and be opposite of each other.

(18 gal/1 hour) x (1 hour / 60 minutes), now we have (0.3 gallons/1 minute) we just have to change gallons to cups

(0.3 gallons/ 1 minute) x (4 quarts/1 gallon) x (2 pints/1 quart) x (2 cups/1 pint)

this comes out 4.8 cups/1 minute

Marcy split her income from last week equally between paying her student loans, rent, and savings. She put $650 in savings. How much did Marcy earn last week?

Answers

Final answer:

Marcy's total weekly income was calculated by multiplying the amount she put in savings ($650) by the number of equal parts (3), resulting in a total of $1950 earned last week.

Explanation:

To find out how much Marcy earned last week, we need to consider that she split her income equally into three parts: paying her student loans, rent, and savings. Given that she put $650 in savings, and each of the three parts is equal, we can calculate her total weekly income by multiplying $650 by 3 (the number of equal parts).

Total weekly income = $650 (amount put in savings) × 3

Total weekly income = $1950

Therefore, Marcy earned a total of $1950 last week.

Six months after a divorce, the former wife and husband each take a test that measures divorce adjustment. The wife’s score is 63, and the husband’s score is 59. Overall, the mean score for divorced women on this test is 60 (SD = 6); the mean score for divorced men is 55 (SD = 4). Which of the two has adjusted better to the divorce in relation to other divorced people of their own gender? Explain your answer to a person who has never had a course in statistics

Answers

Note that
(63 – 60)/6 = 1/2
(59 – 55)/4 = 1
So, in relation to other divorced women, the score of 63 is only 1/2 SD above the average. But in relation to other divorced men, the score of 59 is 1 SD above the average. That means the husband has adjusted better to the divorce in the relation to other divorced people of his gender.

Answers

Best to worst;

8.34/6 = $1.39

7.95/5 = $1.59

12.53/7 = $1.79

5.97/3 = $1.99

Answer: 5.97 for three cans > $12.53 for seven cans > $7.95 for five cans > $8.34 for six cans

Step-by-step explanation:

Since, $12.53 for seven cans

The cost of one can = [tex]\frac{12.53}{7} = 1.79[/tex]

$5.97 for three cans

The cost of one can = [tex]\frac{5.97}{3} = 1.99[/tex]

s$7.95 for five cans

The cost of one can = [tex]\frac{7.95}{5} = 1.59[/tex]

$8.34 for six cans

The cost of one can = [tex]\frac{8.34}{6} = 1.39[/tex]

Since, 1.99 > 1.79 > 1.59 > 1.39

Therefore, the required order of prices,

5.97 for three cans > $12.53 for seven cans > $7.95 for five cans > $8.34 for six cans

To find the students in the group, simply add up the frequency from each mark. I'll give you an example solution, but I challenge you to do this on your own!

For example, say that there are 4 students with 3 marks and 6 students with 4 marks. There are then 4+6=10 total students in the group

To find the mean, simply add up all up the marks with the amount of frequencies and divide it by the amount of students.

Take our example from earlier - we can write it as a list. Since there are 4 students with 3 marks, we have
3, 3, 3, 3 ( 3 four times)
Since there are 6 students with 4 marks, we have
4, 4, 4, 4, 4, 4 (4 six times)

Add them all up, and divide them by the total amount of students (10) to get
(3+3+3+3+4+4+4+4+4+4)/10=(3*4+4*6)/10=36/10=3.6

Good luck, and feel free to ask questions if you're confused!

Answer:

write each equation in standard form using integers. y=2x+5

Answers

standard form : Ax + By = C

y = 2x + 5....subtract 2x from both sides
-2x + y = 5...multiply by -1 to make x positive
2x - y = -5 <=== standard form

To write the equation y=2x+5 in standard form with integers, subtract 2x from both sides to get -2x + y = 5. Then, multiply by -1 to make the coefficient of x positive, resulting in 2x - y = -5.

To write the equation y=2x+5 in standard form using integers, we start by moving the terms involving x and y to one side of the equation and the constant term to the other side. The standard form of a line in two dimensions is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

The given equation is already pretty close, so we subtract 2x from both sides to obtain:

-2x + y = 5

Now, we want A to be non-negative. If A is negative, we can multiply the entire equation by -1 to make A positive.

So, the equation -2x + y = 5 becomes 2x - y = -5 when multiplied by -1. This is now in standard form, with all coefficients being integers.

Students are planning a 3 day hiking trip in the mountains. The hike covers a distance of 18.5 kilometers. The students hike 0.28 of the total distance the first day. If they split the remaining distance equally between the second and third days how far will they hike on day three?

Answers

The students will hike 9.11 KM on day three.

Answer:

They hike 9.11 km on day three

Step-by-step explanation:

Total distance traveled on a 3 day hiking trip in the mountains = 18.5 km

The students hike 0.28 of the total distance the first day.

So, Remaining distance = 18.5 - 0.28 = 18.22

Now we are given that they split the remaining distance equally between the second and third days

So, Distance traveled by them on third = Distance traveled by them on second day = Half of the remaining distance = [tex]\frac{18.22}{2} = 9.11[/tex]

So, they hike 9.11 km on day three
