As per unitary method, the amount it will cost to fill the pool is $2.68
The Unitary Method is a mathematical concept which encourages students to use one single rule or principle to solve a problem. It can be used to solve a variety of mathematical problems in algebra, geometry, and other areas.
In this case, the pool is 10 ft wide. To calculate the capacity of a pool with a rectangular shape, you need to multiply its width by its length and then multiply that result by its depth.
If we assume that the length and depth of the pool are both equal to 10 ft, then the capacity of the pool can be calculated as follows:
=> 10 ft x 10 ft x 10 ft = 1,000 cubic feet.
To convert the capacity to gallons, you need to divide
=> 1,000 / 7.48 = 133.89
gallons of water required to fill the pool.
Finally, to calculate the cost of filling the pool, you just need to multiply the number of gallons by the cost per gallon of water ($0.02).
=> 133.89 x 0.02 = 2.68
This gives us a total cost of $2.68 to fill the pool with water.

Maliyah buys a bus ticket to New Orleans, her favorite city in America. The original price of $120 . She uses a coupon code to get a 20% discount off of the original price . She is then charged a 6% tax on the discounted price . What is the final cost for Maliyah's bus ticket
By using the unitary method, the final cost of Maliyah's bus ticket after the discount and tax was $101.76.
The unitary method involves dividing the original price by the percentage discount and then multiplying the result by the percentage tax to find the final cost.
First, we will find the discounted price of the bus ticket. To do this, we divide the original price of $120 by 100 and multiply by 20 to find the discount amount.
=> $120 / 100 * 20 = $24.
So, the discount amount is $24.
Next, we subtract the discount amount from the original price to find the discounted price.
=> $120 - $24 = $96.
So, the discounted price of the bus ticket is $96.
Finally, we multiply the discounted price by the percentage tax of 6% to find the final cost. To do this, we divide the 6% tax by 100 and multiply by the discounted price.
=> 6 / 100 * $96 = $5.76.
So, the final cost of the bus ticket is
=> $96 + $5.76 = $101.76.

HELP!!!!! Solve for the value of q
Answer:
q = 4
Step-by-step explanation:
The three angles shown lie on the same straight and are adjacent to each other.
Adjacent angles on a linear segment are called supplementary angles and their sum adds up to 180°
Plugging in the expressions for the three angles we get:
(8q + 1) + 90 + 57 = 180
==> 8q + 1 + 90 + 67 = 180
==> 8q + 148 = 180
==> 8q = 180 - 148
==> 8q = 32
q = 32/8 = 4

K A can of beans has surface area 368 cm². Its height is 18 cm. What is the radius of the circular top? .... The radius of the circular top is 4.6 cm. (Do not round until the final answer. Then round to the nearest hundredth as needed.)
Answer: The surface area of a cylinder with height h and base with radius r can be calculated as:
A = 2πr^2 + 2πrh
We know the surface area (A) and the height (h) of the can of beans:
A = 368 cm²
h = 18 cm
We can substitute these values into the formula above and solve for r:
368 = 2πr^2 + 2πrh
368 = 2πr^2 + 2πr * 18
368 = 2πr^2 + 36πr
332 = 2πr^2 + 36πr
2πr^2 + 36πr - 332 = 0
We can use the quadratic formula to solve for r:
r = (-b ± √(b^2 - 4ac)) / 2a
where a = 2π, b = 36π, c = -332
r = (-36π ± √(36π^2 - 4 * 2π * -332)) / 2 * 2π
r = (-36π ± √(1296π^2 + 2664π)) / 4π
r = (-36π ± √(1296π^2 + 2664π)) / 4π
r = (-36π ± √(1296π^2 + 2664π)) / 4π
r = (-36π ± √(1656π)) / 4π
r = (-36π ± √(1656π)) / 4π
r = (-36π ± 40π^(1/2)) / 4π
There are two possible values for r, but only one will result in a positive value for r (the other will give a negative value). So we can use the positive value:
r = (-36π + 40π^(1/2)) / 4π
r = (40π^(1/2) - 36π) / 4π
r = (40π^(1/2) - 36π) / 4π
r = (40π^(1/2) - 36π) / 4π
r = (40 - 36π) / 4π
r = (40 - 36π) / 4π
We can approximate π as 3.14 to calculate the numerical value of r:
r = (40 - 36 * 3.14) / (4 * 3.14)
r = (40 - 113.04) / (4 * 3.14)
r = (40 - 113.04) / 12.56
r = (40 - 113.04) / 12.56
r = -73.04 / 12.56
r = -5.79
Since the radius must be positive, we reject this solution. The only valid solution is:
r = (40π^(1/2) - 36π) / 4π
r = (40π^(1/2) - 36π) / 4π
r = (6.32 - 36π) / 4π
r = (6.32 - 36 * 3.14) / (4 * 3.14)
r = (6.32 - 113.04) / 12.56
r = -106.72 / 12.56
r = -8.49
Since the radius must be positive, we reject this solution as well. There are no valid solutions for r, which means the original statement that "the radius of the circular top is 4.6 cm" is incorrect.
Step-by-step explanation:
The radius of the circular top is 4.6 cm.
What is surface area?
Surface area is total area on the surface of a three-dimensional shape.
The surface area of the can is made up of the sum of the areas of its top and bottom circular faces and its cylindrical side.
Let the radius of the circular top be "r".
The area of the circular top can be found using the formula:
A = πr^2
So, πr^2 = (1/2) * 368 cm²
r^2 = (368 / 2π) cm²
r = √(368 / 2π) cm
Using the value of π = 3.14, we get:
r = √(368 / (2 * 3.14)) cm
r = √(59.0079) cm
r = 4.6 cm
Therefore, The radius of the circular top is 4.6 cm.

The population of a town increased by 1.5% per year from 1995 to 2015.
So, rate of growth is 1.5%.
The town's population at the beginning of 1995 was 16112.
So, initial population is 16112.
And we have to calculate 1 year growth factor.
So, we will use the formula i.e.
x(t) = [tex]x_{o}[/tex] × (1 + r) t
Here, Initially the Population is [tex]x_{o}[/tex] =16112
Growth Rate (%) (r) = 1.5

Simplify using properties of exponents and radicals. ^3√32a¹⁰b^6
The simplified expression is 4a⁵ * b³.
Describe exponents?Exponents are a way to represent repeated multiplication. The exponent of a number represents the number of times the base is multiplied by itself. For example, 2^3 means 2 multiplied by itself 3 times, or 2 * 2 * 2 = 8.
In general, if the base number is b and the exponent is n, then b^n represents b multiplied by itself n times. This can be written as b * b * ... * b (n times). The exponent can be any positive integer or zero, and the base can be any real number.
Exponents have several properties, including the following:
b^0 = 1 for any non-zero base b.
b^1 = b for any base b.
b^n * b^m = b^(n + m) for any base b and positive integers n and m.
(b^n)^m = b^(n * m) for any base b and positive integers n and m.
b^(-n) = 1 / b^n for any base b and positive integer n.
These properties help simplify and manipulate expressions with exponents.
We can simplify the expression using the properties of exponents and radicals as follows:
^3√32a¹⁰b⁶
= ^3√(2⁵ * 2¹ * a¹⁰ * b⁶) [since 32 = 2⁵ and 2¹]
= ^3√(2⁶ * a¹⁰ * b⁶) [using the property of exponents: a^m * a^n = a^(m+n)]
= 2^2 * ^3√(a¹⁰ *b⁶) [since 2⁶ = 2² * 2⁴]
= 2² * a⁵ * b³ [since (^3√(x))³ = x, and since a^m * b^m = (ab)^m]
= 4a⁵ * b³.
So, the simplified expression is 4a⁵ * b³.

This situation is modeled by the given system of equations, where a represents the number of adults and c represents the number of children.
As a result, 315 pupils attended the school play.
What is equation?In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10.
Here,
The first equation in the system is given by the total number of attendees:
c + a = 330
The second equation is given by the number of children being 21 times the number of adults:
c = 21a
We can use substitution to find the value of a and then find the value of c. Substituting the second equation into the first equation, we get:
21a + a = 330
Combining the two terms on the left-hand side, we have:
22a = 330
Dividing both sides by 22, we have:
a = 15
So there were 15 adults in attendance at the school play. To find the number of children, we can use the second equation:
c = 21a = 21 * 15 = 315
So there were 315 children in attendance at the school play.

Preform the multiplication. Simplify your answer if possible
(5 √(3) + √(15)) × (3 √(5) + √(15))
The simplified form for the given problem (5 √(3) + √(15)) × (3 √(5) + √(15)) is 45√(45).To solve the equation we are using the distributive property.
The property which states that the product of a number and the sum of two numbers is equal to the sum of the products of the number and each of the two numbers being added. Using this principle, the problem can be broken down into two separate products, (5 √(3) × 3 √(5)) and (5 √(3) × √(15)) + (√(15) × 3 √(5)).
The first part of the problem can be simplified by combining 5 and 3, which is 15. This leaves 15 √(15). The second part of the problem can be simplified by combining 3 and 5, which is 15. This leaves 15 √(15). Adding the two parts together results in 30 √(15). The √(15) can be multiplied by itself, which is 15. Multiplying 30 by 15 results in 45 √(45). The √(45) cannot be simplified any further, so the final answer is 45√(45).

what is the difference between a line spectrum and a continuous spectrum? provide an example of each.
A line spectrum refers to a type of spectrum where light is emitted at specific, discrete frequencies. A continuous spectrum, on the other hand, refers to a type of spectrum where light is emitted at all frequencies within a given range.
A line spectrum refers to a type of spectrum where light is emitted at specific, discrete frequencies. The light is emitted in a pattern of individual lines, hence the name "line spectrum." Hot gases or plasmas often produce this type of spectrum, and the lines represent specific energies of electrons in the gas.
An example of a line spectrum is the Hydrogen spectrum, which consists of a series of distinct lines of different colours that correspond to different energies of the electrons in a hydrogen atom.
A continuous spectrum, on the other hand, refers to a type of spectrum where light is emitted at all frequencies within a given range. The light is emitted in a smooth, continuous manner, hence the name "continuous spectrum." This type of spectrum is often produced by hot solid objects, such as the sun, and it represents a continuous range of energies.
An example of a continuous spectrum is the spectrum of light emitted by the sun, which spans a wide range of frequencies and has a smooth, continuous appearance.

The area of the shape is x²+2x +1 and the perimeter is 4x +7
What is area and perimeter?The area is the region covered by shape or figure whereas perimeter is the distance covered by outer boundary of the shape. The unit of area is given by square unit or unit2 and unit of perimeter is same as the unit.
The area of the shape is :
The shape is sub divided into 4 with different areas x, x , x², and 1
Therefore the area of the shape = x²+x+x+1 = x²+2x+1
The perimeter is obtained by adding all the sides
x+x+x+x+1+1+1+1+1+1+1 = 4x+7
therefore the perimeter of the shape is 4x+ 7

You want to build a sand castle on the seashore that will last two days. What two things should you consider?
Answer: sand and water
Sand : The first and most important thing you need to know about sand is that you can't do a thing with it unless it's wet. Here's why: when you add water to grains of sand, the liquid forms "bridges" that connect the granules to one another. This is why damp sand sticks together, so you can shape and carve it.
Water : Use lots of water. Dry sand in its natural state is lazy stuff. It wants to lie down and spread out into all sorts of nooks and crannies. The good news is that as long as you keep gravity working for you, there is really no way to add too much water. Which brings us to our second rule.2 Let it drain. If you've ever tried to make the base of a sandcastle by filling a plastic bucket with wet sand and then trying to unmould it, you've seen how important this rule is. With no place for the excess water to drain off, the sand makes a sucking, sticking, vacuum seal with the plastic and it becomes difficult, if not impossible, to remove the bucket.This is why successful sand sculptors do not use plastic buckets or other closed moulds but build their shapes by stacking handfuls of wet sand or by tamping it down in a topless and bottomless form.
Answer:
Placement and shape/size
Step-by-step explanation:
Placement: if the castle is to stay up for two days, you need to take into consideration the tide, and how far up on the seashore it will get. You need to know for a fact the ocean will not touch it, because if it does, chances are it will dig away at the foundation, making it topple over. You also need to make it in a place That little to no people will be there, so that they will not knock it over.
Shape/size: again, if it is to stay up for two days, you need to also consider the other weather than may occur. You need a good foundation that will not topple over. You need it tall enough that if some sand blows away, it will not matter. If it rains, you should have enough sand there that it would stay, and/or have something covering it, protecting it.
