The solutions are 150, 2.5, 39 and 101. The solutions have been obtained using the arithmetic operations.
What are arithmetic operations?
In all, there are four basic mathematical operations which are applicable for all the real number. The operations are as follows:
1.Addition(‘+’) operation which gives the sum of the numbers.
2.Subtraction(‘-’) operation which gives the difference of the numbers.
3.Multiplication(‘×’) operation which gives the product of the numbers.
4.Division(‘÷’) operation which gives the quotient of the numbers.
1. The sum of 6 and the square of 12
The square of 12 = 12*12 = 144
Sum of 6 and 144 = 6 + 144 = 150
2. The quotient of 30 and the sum of 5 and 7
The sum of 5 and 7 = 5 + 7 = 12
The quotient of 30 and 12 = 30 ÷ 12 = 2.5
3. The difference of 4 cubed and 25
The cube of 4 = 4*4*4 = 64
The difference of 64 and 25 = 64 - 25 = 39
4. 5 more than the product of 12 and 8
The product of 12 and 8 = 12*8 = 96
5 more than 96 = 5 + 96 = 101
Hence, the solutions are 150, 2.5, 39 and 101.

What was it in 2020?
Help on question c
Answer:
the total average monthly expenditure in 2020 was £2400.
Step-by-step explanation:
c) To find the total average monthly expenditure in 2020, we need to add up all the individual expenditures in each category. From the given data, we have:
Average monthly expenditure in 2020 = 600 + 500 + 400 + 300 + 200 + 100 = £2400
So, the total average monthly expenditure in 2020 was £2400.
the base of a certain solid is the region r. cross sections through the solid taken perpendicular to the x-axis are squares. an integral that expresses the volume of the solid is:
The integral[tex]$\int_{-\infty}^{\infty} f(x)^2 dx$[/tex] expresses the volume of the solid, where f(x) is the side length of the square cross sections taken perpendicular to the x-axis in the region r.
The given integral [tex]$\int_{-\infty}^{\infty} f(x)^2 dx$[/tex] expresses the volume of the solid whose base is the region r. The integral is calculated by taking the cross sections of the solid perpendicular to the x-axis and consider them as squares. The side length of each square is denoted by f(x). The integral is calculated over the region r, which is the base of the solid. This integral is the sum of the areas of all the squares, which is equivalent to the volume of the solid. The integral is calculated by taking the lower limit of integration as[tex]$-\infty$[/tex] and the upper limit of integration as[tex]$\infty$[/tex]. Hence, the integral [tex]$\int_{-\infty}^{\infty} f(x)^2 dx$[/tex] expresses the volume of the solid with the base region r and square cross sections.

(b) Extend the basis in part (a) to a basis of C5.
(c) Find a subspace W of C5 such that C5 = U direct sum W
a) One possible basis for U is {(1/6,1,0,0,0), (0,0,1,-2,3)}.
b) A basis of C5 is {(1/6,1,0,0,0), (0,0,1,-2,3), (1,0,0,0,0), (0,0,1,0,0), (0,0,0,1,0)}.
c) The basis of W is {(1,0,0,0,0), (0,0,1,0,0), (0,0,0,1,0)}.
Linear Algebra Identificationa) To find a basis of U, we can use the two given equations to solve for two of the variables in terms of the others. From the first equation, we have z1 = z2/6. Substituting this into the second equation, we get z3 + 2z4 + 3z5 = 0. Therefore, one possible basis for U is {(1/6,1,0,0,0), (0,0,1,-2,3)}.
b) To extend this basis to a basis of C5, we need to add three more vectors that are not in the subspace U. These vectors can be any linearly independent vectors that are not in U. One possible set of additional vectors is {(1,0,0,0,0), (0,0,1,0,0), (0,0,0,1,0)}. Therefore, a basis of C5 is {(1/6,1,0,0,0), (0,0,1,-2,3), (1,0,0,0,0), (0,0,1,0,0), (0,0,0,1,0)}.
c) To find a subspace W of C5 such that C5 = U direct sum W, we can take the complement of U in C5. The complement of U is the set of all vectors in C5 that are not in U. Since we have already found a basis for C5, we can simply take the subset of basis vectors that are not in U to form a basis for W. In this case, the basis of W is {(1,0,0,0,0), (0,0,1,0,0), (0,0,0,1,0)}.

Joe’s garden hose fills the pool in hours. His neighbor has a thinner hose that fills the pool in hours. How long will it

The length of time it would have taken for both garden hoses to fill the pool would be 6.67 hours.
How to find the time taken ?To solve this problem, we can use the formula:
1/rate = time
In the case of Joe's hose, the rate is 1/12 of the pool per hour. For his neighbor's hose, the rate is 1/15 of the pool per hour.
So, the combined rate is:
= (1/12) + (1/15)
= (5/60) + (4/60)
= 9/60 of the pool per hour
So, the time it will take to fill the pool using both hoses is:

6. How can you be certain that the angles you have created form a square inside the circle? (4
points for a thorough explanation)
To be certain that the angles created form a square inside a circle, it is important to first understand the properties of a square and a circle.
How to sure that Angles created form a Square inside a Circle?A square is a four-sided polygon with all sides of equal length and all angles of 90 degrees. This means that if we draw a square inside a circle, the four corners of the square should be tangent to the circle.
A circle is a shape with all points on the circumference equidistant from the center. This means that if we draw a square inside a circle, the distance from the center of the circle to the midpoint of each side of the square should be equal to the radius of the circle.
By verifying that the above two conditions are met, we can be certain that the angles created form a square inside the circle. Additionally, we can also check that all the four angle of the square is 90 degrees and the opposite sides are parallel.

Let h be the distance of A from the BCD. Then the distance of A from the line PQ is minimum h, so point E exists provided that the side length maximum is 2h. It is √(3/2) h.
We have by construction AD = AE and EP = AP. Also, since P lies on the line BC, then PA = PD. Hence PA = PA, PD = PE, AD = AE, so PAD and PAE are congruent triangles. Hence E can also be acquired by spinning D about AP. Since M lies on AP, it gives EM = DM.

The length of a new rectangular playing field is 4 yards longer than triple the width. If the perimeter of the rectangular playing field is 416 yards, what are its dimensions?
Answer: Let's call the width of the rectangular playing field "w" and the length "l". From the problem, we know that:
l = 3w + 4 (the length is 4 yards longer than triple the width)
We also know that the perimeter of a rectangle is the sum of the lengths of all four sides, so:
P = 2l + 2w
We are given that the perimeter is 416 yards, so we can substitute that into the perimeter equation:
416 = 2(3w + 4) + 2w
Simplifying and solving for w:
16 = 6w + 8
8 = 6w
w = 8/6 = 4/3
We can now substitute that back into the equation for the length:
l = 3w + 4
l = 3(4/3) + 4
l = 4 + 4
l = 8
So the dimensions of the rectangular playing field are 4/3 yards wide and 8 yards long.

the ratio of the number of people per unit area = 20/(10 × 10) = 20/100 = 1/5
The area, A, occupied by the crowd = 7 feet × 1 mile × 1
1 mile = 5280 feet
A = 7 feet × 5280 feet × 1 = 36960 feet².

= 7392 people.
Therefore, the required value is 7392 people.
