A pool can be filled by one pipe in 4 hours and by a second pipe in 12 hours. How long will it take using both pipes to fill the pool?

Answers

Answer 1

1/t=1/4+1/12=(3+1)/12=4/12=1/3
t=3 hour

Answer 2

The individual pipes can fill the pool in 4 hours and 12 hours respectively then using both pipes together, it will take 3 hours to fill the pool.

Use the concept of fraction defined as:

A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.

Give that,

One pipe can fill the pool in 4 hours.

Another pipe can fill the pool in 12 hours.

The first pipe fills the pool in 4 hours,

So its rate is 1/4 of the pool per hour.

Similarly,

The second pipe fills the pool in 12 hours,

So its rate is 1/12 of the pool per hour.

To find the combined rate, when both pipes are used together,

Add their individual rates:

(1/4 + 1/12) = 3/12 + 1/12 of the pool per hour.

(1/4 + 1/12) = 1/3 of the pool per hour.

Now, to find the time it takes to fill the pool using both pipes,

Take the reciprocal of the combined rate,

1 / (1/3) = 3 hours.

Hence,

Using both pipes together, it will take 3 hours to fill the pool.

Davis Construction is building a new housing development. They begin by mapping the development out on a coordinate grid. They place one of the two swimming pools at coordinate (-16, -25) and the other at (18, 23). If they want the club house to be exactly halfway between the two pools, find the coordinate point for the clubhouse

Answers

To solve this problem, we can use the following ratio formulas to find for the coordinates of the club house:

x = [m / (m + n)] (x2 – x1) + x1

y = [m / (m + n)] (y2 – y1) + y1

Where,

m and n are the ratios (0.5 and 0.5 each since the club house are to be located exactly halfway)

x1 and y1 are the x and y coordinates of the 1st pool (-16, -25)

x2 and y2 are the x and y coordinates of the 2nd pool (18, 23)

Substituting:

x = [0.5 / (0.5 + 0.5)] (18 - -16) + -16

x = 1

y = [0.5 / (0.5 + 0.5)] (23 - -25) + -25

y = -1

Therefore the club house should be located at coordinates (1, -1).

If all of the diagonals are drawn from a vertex of a pentagon, how many triangles are formed?

Answers

A picture helps. There are 2 non-adjacent vertices, so two diagonals can be drawn, resulting in 3 triangles.

Drawing all diagonals from one vertex of a pentagon to the non-adjacent vertices creates three triangles within the pentagon.

When all the diagonals are drawn from one vertex of a pentagon, it divides the pentagon into several triangles.

A pentagon has five sides, and when selecting a single vertex, we can draw diagonals to the non-adjacent vertices. In this case, there are three non-adjacent vertices, which means we can draw three diagonals, thus creating three triangles inside the pentagon.

This is because each diagonal, combined with two sides of the pentagon, forms a triangle.

With that out of the way, take a look at your top equation, y = 3/2x + ?. If you noticed the question mark is in the spot of the B (Y-intercept), we can simply find this by finding where on the graph does the line intercept the Y-axis.

Triangle B shows the Y-intercept to be -7, this means that the hypotenuse intercepts the Y-axis at (0 , -7).

If we were to find the (what I like to call) the interception point of triangle A's hypotenuse and the Y-axis, we find our missing variable.

Just looking at the graph, we can count and visually determine that the Y-intercept of the hypotenuse is (0 , 1).

The manager at an ice cream shop keeps track of the number of deluxe cones and regular cones sold each day and the total money received. On Saturday, a total of 95 cones were sold, and the money collected was $628 . If deluxe cones are sold for $8 and regular cones are sold for $5 , how many deluxe cones and regular cones were sold?

Answers

d + r = 95.....d = 95 - r
8d + 5r = 628

8(95 - r) + 5r = 628
760 - 8r + 5r = 628
-8r + 5r = 628 - 760
-3r = -132
r = -132/-3
r = 44 <== regular cones

d + r = 95
d + 44 = 95
d = 95 - 44
d = 51 <== deluxe cones

Final answer:

By forming a system of equations and applying the elimination method, we conclude that the ice cream shop sold 51 deluxe cones and 44 regular cones on Saturday.

Explanation:

How to Solve for the Number of Deluxe and Regular Cones Sold

To solve for the number of deluxe cones and regular cones sold at the ice cream shop, we need to set up a system of equations. We are given that a total of 95 cones were sold and the total money collected was $628. Deluxe cones are sold for $8 and regular cones for $5. Let's define our variables:

x = number of deluxe conesy = number of regular cones

Now, we can establish our equations:

The total number of cones sold is 95: x + y = 95The total money collected is $628: 8x + 5y = 628

To solve the system, we can use the substitution or elimination method. Let's use elimination for this example.

Multiply the first equation by 5:

5x + 5y = 475

Now subtract this from the second equation:

(8x + 5y) - (5x + 5y) = 628 - 4753x = 153x = 51

With 51 deluxe cones sold, we can substitute that into the first equation to find y:

51 + y = 95y = 95 - 51y = 44

So, 51 deluxe cones and 44 regular cones were sold on Saturday.

Start with the given decimal number: 0.025.

Identify the non-zero digit. In this case, it is 2.

Move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. Count the number of places you moved the decimal point. In this case, we moved the decimal point two places to the right.

0.025 -> 2.5

Write the non-zero digit (2.5) as a decimal number.

Finally, express the power of 10 that represents the number of places you moved the decimal point. Since we moved the decimal point two places to the right, the power of 10 is -2.

Putting it all together, we have:

0.025 = 2.5 × 10⁻²

Two garden plots are to have the same area. One is square and one is rectangular. The rectangular plot is 2 meters wide and 18 meters long. How long is one side of the of the square garden plot in meters?

Answers

area of rectangle = l x w

area of rectangle = 2*18 = 36 square meters

area of square = S^2, or s = square root(area)

sqrt(36) = 6

length of side of square = 6 meters

The side length of the square garden plot with the same area as a rectangular plot of dimensions 2 meters by 18 meters is 6 meters.

The student is asking about finding the length of a side of a square garden plot that has the same area as a rectangular garden plot measuring 2 meters wide by 18 meters long. To find the area of the rectangular plot, we multiply the length by the width: 2 meters imes 18 meters = 36 square meters.

Since the area of the square plot must equal the area of the rectangular plot, we can use the formula for the area of a square, A = s2, where s is the side length of the square. Therefore, to find the side length of the square plot, we take the square root of the area of the rectangular plot:
√(36 square meters) = 6 meters

So, the side length of the square garden plot is 6 meters.

Answers

now, you can expand the squared binomial on the numerator, but there will not be any like-terms to simplify, so, it won't make much difference, so.... you can expand it or not.

Final answer:

The expression for the total area made up by the square and the circle as a function of x is f(x) = x^2/16 + (25 - 10x + x^2)/(4*Pi) square inches.

Explanation:

To solve this problem, you need to know the formulas for the areas of a square (Area = side^2) and a circle (Area = pi * radius^2). If a piece of the wire with length x inches is to be bent into the shape of a square, then each side of the square will be x/4 inches long (since a square has 4 equal sides). Therefore, the area of the square = (x/4)^2 = x^2/16 sq.inches.

The remaining piece of the wire is 5-x inches long and is to be bent into the shape of a circle. The circumference of the circle is 5-x inches (since it uses the remaining wire), therefore the radius of the circle is (5-x)/(2*Pi) inches. Therefore, the area of the circle = Pi*((5-x)/(2*Pi))^2 = (25 - 10x + x^2)/(4*Pi) sq.inches.

The total area made up by the square and the circle is the sum of their areas, therefore the function representing the total area f(x) = x^2/16 + (25 - 10x + x^2)/(4*Pi) sq.inches.

Use appropriate algebra and theorem 7.2.1 to find the given inverse laplace transform. (write your answer as a function of t.) −1 s (s − 5)(s − 6)(s − 30)

Answers

When it comes to laplace equations, there are transformation equations to follow. Generally, when you want to transform a laplace equation, you change the equation from f(t) to F(s). If you do the reverse, it is called the reverse laplace equation.

Based on the given, the useful transformation equation is shown in the attached picture. The given equation is

[tex] \frac{-1}{s(s-5)(s-6)(s-30)} [/tex]

Breaking it into partial fractions,

[tex] \frac{-1}{s} * \frac{1}{s-5} * \frac{1}{s-6} * \frac{1}{s-30} [/tex]

From the given transformation equation:

-1/s ⇔ -e^0t ⇔ 1
1/(s-5) ⇔ e^-(-5t) ⇔ e^5t
1/(s-6) ⇔ e^-(-6t) ⇔ e^6t
1/(s-30) ⇔ e^-(-30t) ⇔ e^30t

Therefore, the laplace equation is equal to 1*e^5t*e^6t*e^30t which is simplified into e^41t,

The area of a rectangular patio is 5 5/8 square yards, and it's length is 1 1/2 yards. What is the patio's width in yards?

Answers

Hello there! Thank you for asking your question here at Brainly. I will be assisting you today with answering this problem, and will be teaching you how to deal with it on your own in the future.

First, let's take a look at our question, and evaluate it.

"The area of a rectangular patio is 5 5/8 square yards, and it's length is 1 1/2 yards. What is the patio's width in yards?"

To clarify this problem, we are looking for the patio's width.

Let's first understand what the area of a rectangular shape is.
The formula for the area of a rectangle is "Length times Width", or "L • W".

So this is how the equation should look like:
A = L • W
We have our area, 5 5/8, and we have our length, 1 1/2.

To make things more simple, let's convert our fractions to decimals. Now, to convert our fractions to decimals, let's set our denominators (the numbers on the bottom of a fraction) equal to another fraction, with x as the numerator (the numbers on the top of a fraction) and 100 as the denominator.

So we have 1/2 and x/100. Divide 100 by 2 to find x (as 1/2 of anything is dividing by 2).
100 / 2 = 50, so 1 1/2 = 1.50 as a decimal.

Now, let's try 5/8.
1/8 = 0.125, so multiply 0.125 by 5.
0.125 • 5 = 0.625.
5 5/8 = 5.625 as a decimal.

So, now we have our equation:
A = L • W
Plug in our numbers.
5.625 = 1.50x

To isolate and solve for x, we need to divide both sides by 1.50, so let's do that.
5.625 / 1.50 = 3.75
1.50x / 1.50 = x

We are now left with:
x = 3.75

Your answer is:
The patio's width is 3.75 yards.

Suppose that a particular artillery piece has a range r = 8320 yards . find its range in miles. use the facts that 1mile=5280ft and 3ft=1yard.

Answers

The range in miles is 4.72 mile

What do you mean by 1 mile?

mile, any of various units of distance, such as the statute mile of 5,280 feet (1.609 km). It originated from the Roman mille passus, or “thousand paces,” which measured 5,000 Roman feet.

Given : range= 8320 yards

1 mile= 5280 feet

3 feet= 1 yard

Now,

8320yards X 3ft = 24,960

Now, divide that by 5,280ft in a mile

= 24960/5280

= 4.72 miles

Hence, range is 4.72 miles.

Final answer:

To convert the artillery piece's range of 8320 yards to miles, you multiply by 3 to change yards to feet and then divide by 5280 to convert feet to miles, resulting in a range of approximately 4.727 miles.

Explanation:

To find the artillery piece's range in miles, starting with its range in yards, we need to use unit conversion factors. Knowing that 1 mile equals 5280 feet and 3 feet equals 1 yard, we can set up a conversion to calculate the distance in miles.

Steps to Convert Yards to Miles:

Convert the given distance from yards to feet by multiplying the number of yards by 3 (since there are 3 feet in a yard).Next, convert the distance from feet to miles by dividing the number of feet by 5280 (since there are 5280 feet in a mile).

For an artillery range of 8320 yards:

8320 yards is equivalent to 8320 yards * 3 feet/yard = 24960 feetThen 24960 feet / 5280 feet/mile gives us the range in miles.

When you divide 24960 by 5280, you get 4.727 miles (rounded to three decimal places).

The function g(x) = 3(x - 3)2 + 2 will translate 3 units to the right. True or False?

Answers

The answer is true, since horizontal shifts are shown in a function by either adding or subtracting a value from the variable. The horizontal shift is (x-3), not (x+3) since in order for (x+3) = 0, x has to equal -3. The x-intercept, if not for the vertical shift of 2, would be 3, not -3, meaning (x-3) is the correct way to represent translating 3 units to the right.

4 students equally share 3/4 of a pizza. How much of the pizza does each student get?

Answers

16/3 of the pizza

3/4 divided by four means you have to take the reciprocal of 3/4 to give you 4/3 and then multiply that by 4 to get 16/3.

Final answer:

To find out how much pizza each of 4 students gets when they equally share 3/4 of a pizza, we divide the amount of pizza (3/4) by the number of students (4). The result is 3/16, which means each student gets 3/16 of the pizza.

Explanation:

The question asks how 4 students can equally share 3/4 of a pizza. In mathematics, to divide a quantity equally amongst a group, we perform division. So, in this scenario, we need to divide 3/4 (the pizza) by 4 (the students).

Step 1: Represent the given scenario as a division problem: 3/4 ÷ 4. Step 2: Convert the division into multiplication by the reciprocal. This changes our problem into a multiplication problem: 3/4 * 1/4. Step 3: Multiply the numerators together to get the numerator of the answer: 3 * 1 = 3. Step 4: Multiply the denominators together to get the denominator of the answer: 4 * 4 = 16.

So, the answer of 3/4 ÷ 4 is equal to 3/16. Therefore, each student gets 3/16 of the pizza.

Which figure has the correct lines of symmetry drawn in?

Answers

The answer is the fourth image.

If you were to fold the hexagon in half, it would be symmetrical when folded from vertex-to-vertex and when folded from the midpoint of a side to the opposite side.

This means that while the first and third images are valid lines of symmetry, they are incomplete because they're missing the second set of lines from side-to-side.
The second image also has valid lines of symmetry, but it doesn't have all of them.

Thus, the answer is the fourth image.
