When p = 0.125 the equation -3p + ( 1/8 ) = ( - 1/4 ) is true.

The given equation is:

-3p + ( 1/8 ) = ( - 1/4 )

On the left-hand side of the equation, the denominator of the two terms is not the same.

So, the LCM of 1 and 8 is 8.

Therefore,

- 3p × ( 8 / 8 ) + ( 1 / 8 ) × ( 1 / 1 ) = ( - 1 /4 )

- 24p / 8 + 1 / 8 = - 1 / 4

( - 24p + 1 ) / 8 = - 1 / 4

Now multiplying each side of the equation by 8.

We get,

[ ( - 24p + 1 ) / 8 ] × 8 = ( - 1 / 4 ) × 8

- 24p + 1 = - 8 / 4

- 24p + 1 = - 2

Subtracting 1 from each side of the equation,

- 24p + 1 - 1 = - 2 - 1

-24p = - 3

Now, divide each side of the equation by 24.

- 24p / 24 = - 3 / 24

- p = ( - 1 / 8 )

Multiplying by - 1 on each side of the equation,

( - p ) × ( - 1 ) = ( - 1 / 8 ) × ( - 1 )

p = 1 / 8

p = 0.125

The value of p = 0.125 will make the equation true.

Using linear function concepts, it is found that:

i) The equation of BC is given by: [tex]y = -\frac{2}{3}x + \frac{20}{3}[/tex].

ii) The coordinates of C are C(0,10) and the coordinate of D are D(14,6).

The diagram is missing, and is shown in the graph at the end of the answer.

A linear function is modeled by:

y = mx + b

In which:

For this problem, the coordinates are given as follows:

A(2, 14), B(-2,8) and C(x,0).

From the diagram, AB and BC are perpendicular, meaning that the multiplication of their slopes is of -1.

Given two points, the slope is given by change in y divided by change in x. Hence the slope of AB is given as follows:

mAB = (8 - 14)/(-2 - 2) = 3/2.

The slope of BC is given as follows:

mBC = (0 - 8)/(x - (-2))

mBC = -8/(x + 2).

The multiplication of the slopes is of -1, hence:

mAB x mBC = -1

-12/(x + 2) = -1

- x - 2 = -12

x = 10.

Hence, the slope of BC is:

mBC = -8/(x + 2) = -8/12 = -2/3.

Then:

y = -2/3x + b.

When x = 10, y = 0, hence we can find b as follows:

0 = -2/3(10) + b

b = 20/3.

Hence:

The equation of BC is given by: [tex]y = -\frac{2}{3}x + \frac{20}{3}[/tex].

From the diagram, we also have that AB and CD are parallel, meaning that they have the same slope, hence, considering D(x,y), we have that:

mCD = mAB

y/(x - 10) = 3/2

y = 1.5(x - 10)

y = 1.5x - 15.

AD and BC are also parallel, hence:

mAD = mBC

(y - 14)/(x - 2) = -2/3

Since y = 1.5x - 15, we have that:

(1.5x - 15 - 14)/(x - 2) = -2/3

(1.5x - 29)/(x - 2) = -2/3

3(1.5x - 29) = -2(x - 2)

4.5x - 87 = -2x + 4.

6.5x = 91

x = 91/6.5

x = 14.

y = 1.5x - 15 = 1.5(14) - 15 = 21 - 15 = 6.

Hence:

The coordinates of C are C(0,10) and the coordinate of D are D(14,6).

The 2021st term of the sequence is (- n - 2017).

Given,

A sequence is constructed by listing all the possible numbers that contain no digit greater than 3 in ascending order.

We need to find out what is the 2021st term of this sequence.

An arithmetic sequence is a sequence where the difference between the consecutive terms is the same.

Example: 2, 4, 6, 8, 10

4 - 2 = 2

6 - 4 = 2

8 - 6 = 2

The nth term of an arithmetic sequence is given by:

= a + ( n - 1 ) d

Where a = the first term

d = common difference

Let the sequence that contains no digit less than 3 in ascending order be:

3 - n, 3 - (n + 1), 3 - (n+2), 3 - (n+3), 3 - (n+4),......

Where n = any real number from 1.

We see that the common difference is -1.

3 - (n+1) - (3 - n)

= 3 - n - 1 - 3 + n

= -1

3 - (n+2) - [3-(n+1)]

= 3 - n - 2 - 3 + n + 1

= -1

Find the 2021st term.

We have,

a = 3 - n

d = -1

n = 2021

= a + ( n - 1 ) d

= (3 - n) + ( 2021 - 1 ) (-1)

= 3 - n - 2020

= - n - 2017

Thus the 2021st term of the sequence is - n - 2017.

The correct option is Quantity a: the number of prime numbers between 0 and 100, inclusive is greater.

A prime number is a natural number greater than 1 that is not the sum of two lesser natural numbers (or a prime). Any natural number greater than one that is not prime is referred to as a composite number. For instance, the product 1 5 and 5 1 are the only two ways to write the number 5, making it a prime. The fact that it is the sum of two smaller integers (2 x 2), 4, however, makes it composite. Primes play a significant role in number theory because of the fundamental theorem of arithmetic, it states that any natural number greater than one is either a prime number itself or may be factored as a unique prime product up to the order of the primes. the prime number (or a prime).

The number of primes reduces almost exponentially as we move up the number line. The prime numbers between 0 and 100 are therefore far more numerous than those between 101 and 200. It is crucial to understand this general number theory point, but it may also be rapidly illustrated by attempting to find some primes in these two groups.

Also, the depth of aquarium = 3/5 meters

To find the unit rate in minutes per meter, we will simply keep the values in formula. We do not need to change the units, as they are already in required ones, which are minutes and meters.

Unit rate = minutes ÷ meter

Unit rate = 15/2 ÷ 3/5

Rewriting the fraction

Unit rate = 15×5 ÷ 3×2

Performing multiplication in both numerator and denominator

Unit rate = 75 ÷ 6

Performing division of both numerator and denominator by 3

Answer:

h = 16.0 cm

Step-by-step explanation:

Note: I am assuming that the surface area of 258 is the total surface area which includes the Lateral Area (L) and Base Area(B)

Total Surface Area of a right cone

= Lateral Area(L) + Base Area(B)

All numbers in intermediate calculations are rounded to tenth of centimeter i.e. 1 decimal point

Base Area is the area of the circle with radius 4 = [tex]\displaystyle \pi \cdot16 = 50.3[/tex] cm²
Total Area = 258 cm²

So Lateral Area = 258 - 50.3 = 207.7 cm²

Lateral Area is given by the formula
[tex]\displaystyle L = \pi r s \textrm{ where s is the slant height }[/tex]

So we get

[tex]\displaystyle \rm pi \cdot 4 \cdot s = 207.7\\\\\textrm {This gives } s = \dfrac{207.7}{4\pi} = 16.5\\\\[/tex] cm

Slant height is given by the formula:
[tex]s = \sqrt{r^2 + h^2} \textrm{ where r is the radius and h the height}[/tex]
Plugging in values we get
[tex]16.5 = \sqrt{4^2 + h^2} = \sqrt{16 + h^2}[/tex]

Square both sides
[tex]16.5^2 = 16 + h^2[/tex]

==> [tex]h^2 = 16.5^2 - 16 = 256.25\\\\h = \sqrt{256.25} = 16.003 = 16.0[/tex]  rounded to 1 decimal place

So final answers is h = 16 cm

We know that when two lines intersect then the vertically opposite angles are equal.

So according to the given figure

      (11x + 47)° = (6x + 77)°

Solving the above equation for x we get

        11x° + 47° = 6x° + 77°

         5x° = 30°

          x = 6°

Thus the value of x is 6°

Also note that the linear pair of angles make 180°. That is sum of the two angle is 180°. As we can see from the figure ∠z  and (6x + 77)° make linear pair of angles, therefore there sum will be equal to 180°.

Thus,   ∠z  + (6x + 77)° = 180°

             ∠z + (6*6 + 77)° = 180°

the ratio is 4:8:5 for Richard, Allan and Fliss.

the sequence is important.

the money pool between them has 4+8+5 = 17 equal units.

Richard has 4 units of these 17, Allan has 8 units, and Fliss has the remaining 5 units.

we don't know the value of such a unit yet.

this we get from the second hint :

Allan gets £9 more than Fliss.

remember, Allan has 8 units, Fliss 5.

so, Allan has 3 units more than Fliss.

that means these 3 units are worth £9.

and that means each unit is worth 9/3 = £3.

Richard has 4 units, that means he has

As per the information in question, let the smaller number x. So, according to question, large number will be (x + 16).

Now, writing the equation that will form -

x + x + 16 = 56

Performing addition of variables on Left Hand Side

2x + 16 = 56

Shifting the number from Left Hand Side to Right Hand Side

2x = 56 - 16

Performing subtraction on Right Hand Side

2x = 40

Shifting 2 to denominator on Right Hand Side

x = 40÷2

Performing division to find the value of x

x = 20

So, smaller number is 20.

Side length of Rhombus ABCD is  8+2√2 unit

EFGH is a rectangle :

We know that ,

E, F , G , H are midpoints of AB, BC, CD , DA respectively

Since ABCD is a rhombus

AB = BC = CD = DA

AB ll CD  and BC ll DA

since,  E, F , G , H are midpoints of AB, BC, CD , DA respectively

from the figure below we can say that ,

1) AB ll CD ll FH and AB= CD = FH

2) BC ll DA ll GE and BC = DA = GE

Using mid point theorem we can say that ,

GH = EF = 1/2 AC and FG= EH = 1/2 BD

Since for the figure EFGH opposite sides are equal and and parallel , and the diagonals are equal in length we can say that EFGH is a rectangle.

Perimeter of a rectangle = 2(a+b) = 2( GH + EH ) = 2 (EF + GF) = 2 ( 1/2 AC + 1/2 BD )

= 2 x 1/2 ( AC + BD ) = 16

⇒ AC + BD = 16  (1)

now area of a rectangle is given by

A = ab = GH x EH = EF x GF = 1/2 AC x 1/2 BD = 1/4 (AC x BD) = 14

⇒AC x BD = 14 x 4 = 56

from equation (1)

AC ( 16 - AC) = 56

= 16 AC - AC ^2 = 56

⇒ AC^2 - 16 AC + 56 = 0
