A water tank holds 276 gallons but is leaking at a rate of 3 gallons per week. A second water tank holds414 gallons but is leaking at a rate of 5 gallons per week. After how many weeks will the amount of waterin the two tanks be the same?The amount of water in the two tanks will be the same inweeks.
Answers
In order to solve the problem we will first create equations to represent the volume of water on the gallons through the weeks. The output of the functions will be the volume of each and the entry will be the number of weeks passed.
For the first one:
[tex]\text{vol(week) = 276 -3}\cdot week[/tex]While on the second one:
[tex]\text{vol(week) = 414 -5}\cdot week[/tex]In order to calculate the number of weeks it'll take until they have the same volume of water we need to find the "week" which would make them equal. So we will equate both expressions and solve for that variable.
[tex]\begin{gathered} 276\text{ - 3}\cdot week\text{ = 414 - 5}\cdot week \\ 5\cdot\text{week - 3}\cdot week\text{ = 414 - 276} \\ 2\cdot\text{week = }138 \\ \text{week = }\frac{138}{2}\text{ = }69 \end{gathered}[/tex]It'll take 69 weeks for the tanks to have the same volume.
A person invests $9000 at 3% interest compound annually for 4 years and then invests the balance (the $9000 plus the interest earned) in an account at 7% interest for 8 years. find the final value of the investment.
Answers
Answer:
$17,404.5
Explanation:
To calculate the balance after t years, we can use the following equation:
[tex]A=P(1+r)^t[/tex]Where P is the initial investment and r is the rate.
So, we can calculate the balance after 4 years, replacing t by 4, r by 3%, and P by $9000. Therefore the balance is:
[tex]\begin{gathered} A=9000(1+0.03)^4 \\ A=9000(1.126)_{} \\ A=10129.579 \end{gathered}[/tex]Now, we can use this quantity to calculate the final value of the investment. So, replacing P by 10129.579, r by 7%, and t by 8 years, we get:
[tex]\begin{gathered} A=10129.579(1+0.07)^8 \\ A=10129.579(1.718) \\ A=17404.503 \end{gathered}[/tex]Therefore, the final value of the investment is $17,404.5

6. Point A (-16,8) is one of the verticesof a rectangle. After a dilation of 1/2, arotation of 90 degrees clockwise, and areflection over the x-axis, what are thecoordinates of A"'?
Answers
Given the coordinate: A(-16, 8), let's perform the following:
First step:
A dilation with a scale factor of 1/2.
Here, we are to multiply the coordinates by 1/2.
A(-16, 8) ==> A'(-16*½, 8*½) = A'(-8, 4)
Second step:
Perform a rotation of 90 degrees clockwise.
(x, y) will change to (y, -x)
A'(-8, 4) ==> A''(4, 8)
Third step:
A reflection over the x axis.
To perform a reflection over the x axis, (x, y) becomes (x, -y)
A''(4, -8) ==> A'''(4, -8)
Therefore, the coordinates of A''' are:
A'''(4, -8)

Answers
The length of the second painting is 9 inches.
Given,
The area of the first painting = 63 square inches
Length of the first painting = 7 inches
The area of the second painting = 81 square inches
Width of the first painting = Width of the second painting = x
We have to find the length of the second painting:
Here,
We can consider the painting as a rectangle.
Area of rectangle = length × width
Now,
First painting:
Area = length × width
63 = 7 × x
x = 63/7 = 9
That is, the width of the first painting is 9 inches.
The width of the second painting also 9 inches.
Now,
Second painting:
Area = length × width
81 = length × 9
length = 81/9 = 9
Therefore, the length of the second painting is 9 inches.

Algebra, on the other hand, deals with the limitations and guidelines that apply to all other types of numbers, including whole numbers, integers, fractions, functions, and so on. Arithmetic math serves as the foundation for algebra, which always adheres to its definition. A large range of subjects fall within the broad definition of mathematics, which encompasses a very broad range of topics. Beginning with the fundamentals like addition, subtraction, and division of numbers, they then move on to more complicated topics like exponents, variations, sequence, progression, and more. This part does touch on some of the mathematical formulas and mathematical sequence. Four essential mathematical operations—addition, subtraction, multiplication, and division—are covered in basic arithmetic.

It is to be noted that the correct graph is graph A. This is because it shows the coordinates (2, 25). See the explanation below.
What is the calculation justifying the above answer?It is information given is the rate of change of the linear relationship between the stated variable variables:
Number of Bottles; andTime.The ratio given is depicted as:
r = [250 bottles]/ [20 mintures]
r = 25/2 bottles per min
By inference, we know that our starting point coordinates (0,0), because zero bottles were filled at zero minutes.
Thus, we must use the point-slope form to arrive at the equation that exhibits or represents the relationship of the linear graph.
The point-slope form is given as:
y-y₁ = m(x-x₁)
Recall that our initial coordinates are (0, 0,) where x₁ = 0 and y₁ = 0. Hence
⇒ y - 0 = 25/2(x-0)
= y = 25x/2
Hence, if x = 2, then y must = 25
Proof: y = 25(2)/2
y = 50/2
y = 25.
Hence, using the principle of linear relationships, the first graph is the right answer, because it shows the points (2,25) which are part of the relation.

The length of a rectangle is given by a number, x (metres). The width is two metres longer than the length. The area of the rectangle is 120 m^2
Answers
metersGiven:
a.) The length of a rectangle is given by a number, x (meters).
b.) The width is two meters longer than the length.
c.) The area of the rectangle is 120 m^2.
Let's first recall the formula for getting the area of the triangle.
Area = L x W
Where,
L = Length
W = Width
The width is two meters longer than the length. Therefore, we can say that:
W = L + 2
Let's now determine the measure of the dimension of the rectangle:
Let,
x = length of the rectangle
We get,
[tex]\begin{gathered} \text{ A = L x W} \\ 120\text{ = L x (L + 2)} \\ 120=L^2\text{ + 2L} \\ L^2\text{ + 2L - 120 = 0} \\ (L\text{ - 10)(L + 12) = 0} \end{gathered}[/tex]Based on the relationships given, the Length of the rectangle has two possible measures.
L - 10 = 0
L = 10 m
L + 12 = 0
L = -12 m
Since a length must never be a negative value, the length of the rectangle must be 10 m.
For the width, we get:
W = L + 2 = 10 + 2 = 12 m
Summary:
Length = 10 m
Width = 12 m
