Tom had 60 dollars as his pocket money initially.
Let's assume that Tom had x dollars as his pocket money.
He spent 2/3 of his pocket money on apples, which means he spent (2/3)x dollars on apples.
He had 1/3 of his pocket money left after buying the apples.
Out of the remaining money, he spent 1/4 on bananas, which means he spent (1/4)(1/3)x = (1/12)x dollars on bananas.
The total amount spent on apples and bananas is given as $45. So, we can write the equation:
(2/3)x + (1/12)x = 45
Multiplying both sides by 12 to get rid of the fractions:
8x + x = 540
Simplifying, we get:
9x = 540
Dividing both sides by 9:
x = $60

Mr. Moore has a rectangular prism shaped planter box to grow herbs inside his house. The dimensions of the planter box are 4. 5 feet long, 2 feet wide, and 1. 5 feet tall. How any cubic feet of soil does Mr. Moore need in order to fill the planter box
Mr. Moore needs 13.5 cubic feet of soil to fill the planter box.
To calculate the volume of the rectangular prism planter box, we need to multiply the length, width, and height of the box.
Volume = length x width x height
V = 4.5 ft x 2 ft x 1.5 ft
V = 13.5 cubic feet
Therefore, Mr. Moore needs 13.5 cubic feet of soil to fill the planter box.
It is important to note that the volume of the box represents the amount of space inside the box and does not take into account any obstructions or irregularities that may be present inside the box.
Thus, the actual amount of soil required may be slightly different from the calculated value. Additionally, it is always a good idea to add some extra soil to account for settling and to ensure that the planter box is completely filled.

How can I solve this?
In conclusion, we need to identify the set of values of x for which either f(x)=-1/4 or f(-x)=-1/4 in order to solve to the equation f(|x|)=-1/4.
How is a function solved?The expression f(|x|)=-1/4 indicates that the absolute value of x's function f is equal to 1/4. Any x values that satisfy this equation are what we are trying to find. We can rewrite the equation as f(x)=-1/4 when x is positive and f(-x)=-1/4 when x is negative because the absolute value of x is always positive.
We must search for values of x such that f(x)=-1/4 or f(-x)=-1/4 in order to identify the answers. Without knowing more about the function, f may be anything, hence we cannot know the precise solutions.
Therefore, we can state that x or -x is a solution to the equation if there is a value of x such that f(x)=-1/4 or f(-x)=-1/4.
As a result, we must identify the range of x values for which either f(x) or f(-x) = 1/4.

i. The points of intesection of the common chords of the curve x² + y² = 4 and y² = 3x are
(1, √3) and (1,-√3)ii. The points of intesection of the common chords of the curve x² + y² = 4 and x² - 4y + 1 = 0 are
(√3, 1) and (-√3, 1)What are common chords of a circle?The common chords of circles are the chords that pass through the points of intersection of the curves.
i. Given the curve x² + y² = 4 and y² = 3x. We desire to find their points of intesection of the common chords. We proceeds as follows.
Since x² + y² = 4 and y² = 3x. Substituting the second equation into the first, we have
x² + y² = 4 and y² = 3x.
x² + 3x = 4
Re-arranging, we have
x² + 3x - 4 = 0
Factorizing the quadratic equation, we have
x² - x + 4x - 4 = 0
x(x - 1) + 4(x - 1) = 0
(x + 4)(x - 1) = 0
⇒ x + 4 = 0 and x - 1 = 0
⇒ x = - 4 and x = 1
Now, y² = 3x.
⇒ y = ±√3x
So.substituting x = -4 into the equation, we have
y = ±√3x
y = ±√(3 × -4)
= ±√(-12)
Since the square root is negative, this answer is invalid.
Substituting x = 1 into y, we have
y = ±√3x
y = ±√3(1)
y = ±√3
So, the points of intersection are (1, √3) and (1,-√3)
ii. Given the curve x² + y² = 4 and x² - 4y + 1 = 0. We desire to find their points of intesection of the common chords. We proceeds as follows.
Since x² + y² = 4 and x² - 4y + 1 = 0. From the second equation, we have
x² = 4y - 1
Substituting this equation into the first, we have
x² + y² = 4 and x² = 4y - 1
y² + 4y - 1 = 4
Re-arranging, we have
y² + 4y - 1 - 4 = 0
y² + 4y - 5 = 0
Factorizing the quadratic equation, we have
y² - y + 5x - 5 = 0
y(y - 1) + 5(y - 1) = 0
(y + 5)(y - 1) = 0
⇒ y + 5 = 0 and y - 1 = 0
⇒ y = - 5 and y = 1
Now, x² = 4y - 1
⇒ x = ±√(4y - 1)
So, substituting y = -5 into the equation, we have
x = ±√(4y - 1)
x = ±√[(4 × -5) - 1)]
= ±√(- 20 - 1)
= ±√-21
Since the square root is negative, this answer is invalid.
Substituting y = 1 into x, we have
x = ±√(4y - 1)
x = ±√(4(1) - 1)
x = ±√(4 - 1)
x = ±√3
So, the points of intersection are (√3, 1) and (-√3, 1)

A fraction is what?Any combination of like-sized pieces or portions can represent a whole. Standard English defines "quantity" as "a portion" of a particular measure. 8, 3/4. Wholes also include fractions. In mathematics, numerals are expressed by the ratio of quotient to ratio. Every one of these fractions of integers are simple fractions. The fraction contains a fraction, but the fraction's remainder is a challenging fraction. because the values, 4.91, and numerators of real fractions can vary.
Here,
We can begin by isolating the variable with one side of the solution in order to solve for y. The reciprocal of fraction on the left side of the equation can be used to add both sides of the equation to achieve this:
=> 2/5 = (y - 4)/3
=> 3 * 2/5 = y - 4 [add 3 to both ends]
=> 6/5 = y - 4 [simplify]
=> y = 6/5 + 4 [Adjust both ends by 4]
=> y = 6/5 + 20/5 Using the denominator 5 as the corresponding fraction, write 4.
=> y = 26/5
Y is therefore equivalent to 26/5.

The price of an item that is normally £120 after a 20% discount is £96.
To find the price of an item that is normally £120 after a 20% discount,
Calculate the discount amount: To find the discount amount, multiply the original price (£120) by the discount rate ( 20% ) in decimal form:
Discount amount = Original price x Discount rate
= £120 x 0.2
= £24
Calculate the sale price: To find the sale price, subtract the discount amount from the original price:
Sale price = Original price - Discount amount
= £120 - £24

also be roots?
There is no one definite answer.
Given information: If 3 −2√5 and 6 + ???? are roots of P(x), what other numbers must also be roots?To find out the other roots of P(x), we have to make use of the Fundamental theorem of algebra which states that every polynomial of degree n has n roots, both real and complex.In order to find out the other roots, we have to divide the polynomial P(x) by its given roots i.e (x-(3-2√5))(x-(6+????)) = 0Let's begin by solving the first root:Since, If 3 −2√5 is the root, thus we can write, x - (3 - 2√5) = 0Or, x - 3 + 2√5 = 0Or, x = 3 - 2√5Similarly, for the second root, 6 + ???? ,
we can write: x - (6 + ???? ) = 0Or, x = 6 + ????Now, Let's combine these two roots and write the polynomial in factored form. Using these two roots, we can write the equation as below: Thus, P(x) = (x - 3 + 2√5)(x - 6 - ???? ) = 0We have found the other roots to be: Other roots = (x - 3 + 2√5)(x - 6 - ???? ) = 0Where ???? can be any value.
