Answer:

x = 40

Step-by-step explanation:

We can set up the following equations to represent the problem:

x = number of quarters

x + 16 = number of dimes

0.25x + 0.1(x + 16) = 12.45

Solving for x, we get:

x = 40

So there are 40 quarters and 56 dimes in the coin bank.

2 is a prime number, but all other even numbers are composite, since they're all multiples of 2

The arc angle mWX is 9 degrees.

An inscribed angle is the angle that is formed by the intersection of two chords on the circumference of a circle. Therefore, inscribed angles subtended by the same arc are equal.

Hence,

3x - 20 = 15x - 64

3x - 15x = - 64 + 20

- 12x = -44

divide both sides by -12

x = -44 / -12

x = 3.7

Let's find the arc angle

Hence,

mWX = 3(3.7) - 20

mWX = 11 - 20

mWX = 9 degrees

The answer can't be negative.

a) The enlargement needed to be done is 25%.

b) The succession time should be at least t=9 to get a final copy that is less than 15% of the original size.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Let the size of the page be q, when it is reduced to 80%, its size becomes

= 80% x q

= 0.80(q)

= 0.80q

When you want to return it into its original size q,

x(0.80q) = q

x = q / 0.80q

x = 1.25

x= 125%

Hence, the enlargement needed to be done is 25%.

b) The size of the page after t number of copying done is given by

C(t) = [tex]C_0(0.80)^t[/tex]

So, C(t) / [tex]C_0[/tex] = [tex](0.80)^t[/tex]

0.15 ≤  [tex](0.80)^t[/tex]

Taking log on both side

log (0.15) ≤ log [tex](0.80)^t[/tex]

log (0.15) ≤ t log (0.80)

log (0.15) /log (0.80)  ≤ t

0.80 ≤ t

The equation in slope intercept form is : [tex]y = \frac{1}{8} x - 223.05[/tex]

The slope intercept form is a process used to determine the equation of a straight line in the coordinate plane. It can be used to determine the equation of a line when given the slope of the straight line and the y-intercept

The slope-intercept form of a line is:

y = mx+b

where m is the slope of the line and b is an intercept of the y-axis.

[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

[tex]m = \frac{26.7 - 23.2 }{1998- 1970}[/tex]

[tex]m = \frac{1}{8}[/tex]

So,

[tex]y = \frac{1}{8} x + b[/tex]

To find b we get the point (1970, 23.2) and introduce it in the previous equation.

[tex]23.2= \frac{1}{8} (1970)+ b[/tex]

⇒ 23.2 - 246.25 = b

⇒ b = - 223.05

The following are the respective values of the angles:

∠5 = 44°

∠3 = 117°

x = 60°

x = 157°

angles (∠5 + ∠6)° and ∠2 are corresponding angles and are equal so;

∠5 + 90° = 134°

∠5 = 134° - 90°

∠5 = 44°

angles (∠5 + ∠6)° and ∠3 are alternate angles and are equal so;

∠3 = ∠5 + ∠6

∠3 = 27° + 90°

∠3 = 117°

(x + 5) + 90° + (180° - 155°) = 180° {sum of interior angles of a triangle}

x + 5 + 90° + 25° = 180°

x + 120° = 180°

x = 180° - 120°

x = 60°

x = 22° + (180° - 45°) {exterior angle of a triangle equals two opposite interior angles}

x = 22° + 135°

x = 157°

Therefore, the following are the values of the angles: ∠5 = 44, ∠3 = 117°, x = 60°, and x = 157° respectively.

Step-by-step explanation:

To find the size of a rectangular monitor measured diagonally, you can use the Pythagorean theorem. The Pythagorean theorem states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Here are the steps to calculate the diagonal size of the monitor:

Therefore, the size of the rectangular monitor that is 30 centimeters wide by 24 centimeters high is approximately 38.3 cm. to the nearest centimeter.

The size of the given mirror as a rectangular diagonal is 38.41 cm which is almost 39 cm.

We know that;

d=√ {(l)^2 + (w)^2}.........(i), where,

d= diagonal of the rectangle,

l= length of the rectangle = 30 cm

w= width of the rectangle = 24 cm.

Therefore, Substituting the values of each in equation (i), we get;

d=√{(30)^2+(24)^2} cm,

or, d = 38.41 cm

Answer:

The median is 79.

Step-by-step explanation:

The solution to the given differential equation is a 3-dimensional vector function which satisfies the given initial conditions. The vector function consists of three components, one for each dimension in the equation.

The given differential equation is a 3-dimensional vector equation, of the form ()=⟨12−12,2−1,1⟩. The initial conditions are (1)=⟨0,0,12⟩ and ′(1)=⟨8,0,0⟩. The solution to this equation is a 3-dimensional vector function, ()=⟨, ,⟩. The first component of the vector function is a function of the independent variable, and must satisfy the initial condition (1)=⟨0,0,12⟩. This means that the first component of the vector function must be equal to 0 at x=1. The second component must satisfy the initial condition ′(1)=⟨8,0,0⟩. This means that the second component of the vector function must be equal to 8 at x=1. The third component of the vector function must also satisfy the initial condition (1)=⟨0,0,12⟩. This means that the third component of the vector function must be equal to 12 at x=1. Once the initial conditions have been satisfied, the  equation can be solved to find the vector function.

The mathematical expression boole’s inequality for a sequence of events a1, a2, . . . , an then the bounds are known as Bonferroni inequalities [13].

Arithmetic sequence is [tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1) d ; n > 1

The given equation about an arithmetic sequence is

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1) d ; n > 1

Boole's inequality(or the union bound) states that for any at most countable collection of events, the probability that at least one of the events happens is no greater than the sum of the probabilities of the events in the collection.

The objective is to prove the statement using principle of mathematical induction.

The principle of mathematical induction statement that a statement [tex]p_{n}[/tex] about positive integer n, is true if satisfies the following two conditions:

[tex]p_{1}[/tex] is true

If [tex]p_{k}[/tex] is true, then [tex]p_{k+1}[/tex] is true

Consider the statement for n > 1

[tex]p_{n}[/tex] : [tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1) d

Here, it is known that [tex]a_{n}[/tex] is an arithmetic sequence with [tex]a_{1}[/tex] as first term and 'd' as common difference.

Recall that in any arithmetic sequence, each term is determined by adding 'd' to previous term.

Hence, the second term is determined by adding 'd' to first term.

[tex]a_{2}[/tex] = [tex]a_{1}[/tex] + d

For [tex]p_{2}[/tex] , substitute n = 2 in the given statement to verify it for first positive integer.

[tex]p_{n}[/tex] : [tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1) d

[tex]p_{2}[/tex] : [tex]a_{2}[/tex] = [tex]a_{1}[/tex] + (2-1) d

[tex]p_{2}[/tex] : [tex]a_{1} +d[/tex] =   [tex]a_{1} +d[/tex]

This has given a true statement.

Hence, the statement is verified for [tex]p_{1}[/tex].

Therefore,

The mathematical expression boole’s inequality for a sequence of events a1, a2, . . . , an then the bounds are known as Bonferroni inequalities [13].

According to the question, the closing balance for quarter 2 is £82,750.

A quarter is one fourth of a year. It is typically a three month period, usually consisting of January, February, and March; April, May, and June; July, August, and September; or October, November, and December. The terms of a quarter can vary depending on the context. For example, in the United States, quarters are commonly referred to as “fiscal quarters,” and begin on the first day of October, January, April, and July. In this case, each quarter covers a three-month period.

Inflows for quarter 2: 540,000 x 1.075 = £581,000

Outflows for quarter 2: 495,000 x 1.05 = £519,250

Closing balance for quarter 2:

Opening balance + Inflows - Outflows =
