If B is the midpoint of AC and C is the midpoint of BD, then AB=CD.

Given that B is midpoint of AC and C is the midpoint of BD.

We are required to prove that AB is equal to CD.

Midpoint is the point which divides the line segment into two equal parts.

If B is midpoint of AC then,

2AB=AC-----1

2BC=AC-----2

If C is midpoint of BD then,

2BC=BD-----3

2CD=BD-----4

From 1 & 2

2AB=2BC

AB=BC

Put the value of BC from 3.

AB=BD/2

Now put the value of BD from 4.

AB=2CD/2

AB=CD

Hence proved

Hence if B is the midpoint of AC and C is the midpoint of BD, then AB=CD.

Therefore, the surface area of the tea bag is 56 cm².

The slant height of the tea bag is l.

l = 5 cm

Each edge of the base of the tea bag = 4 cm

The lateral surface area of tea is L.

The Surface area of the tea bag is S.

The perimeter of the tea bag is p.

The lateral surface of the tea bag is,

[tex]Lateral \: Surface \: Area = \frac{1}{2} \times Perimeter × Slant \: height [/tex]

[tex]L = \frac{1}{2} \times p \times l[/tex]

[tex] = \frac{1}{2} \times 16 \times 5[/tex]

= 40 cm²

The lateral surface area of the tea bag is 40 cm².

Base Area = (4) ²

= 16 cm²

The surface area of the tea bag is,

Surface Area = Lateral surface area + Base area

S= 40 + 16

The value of r is 21 when s = -1 , t = 4 and  u = 1/5 for the equation r = 3s² + 5 (t - 2u).

Quadratic Equation:

Quadratic equations are the polynomial equations of degree 2 in one variable of type.

The general form of a quadratic equation is,

f(x) = ax² + bx + c = 0

where a, b, c, ∈ R and a ≠ 0.

‘a’ is called the leading coefficient and

‘c’ is called the absolute term of f (x).

Given,

Equation is,

r = 3s² + 5 (t - 2u).

Here we need to find the value of r when the values of s = -1 , t = 4 and  u = 1/5.

Apply the values on the given equation then we get,

=> r = 3 (-1)² + 5 ( 4 - 2(1/5))

Expand the values,

=> r = 3 (-1)² + 5( [20 -2] /5)

Here the value 5 is getting cancelled then we get,

=> r = 3(-1)² + 18

We know that the value of (-1)² = 1

So,

=> r = 3(1) + 18

=> r = 3 + 18

=> r = 21

Therefore, the value of r is 21.

Step-by-step explanation:

To find the multiplication expression, use the Keep, Change, Flip (KCF) method.

The distance between each pair of parallel lines with the given equations y = x-11 and y = x-7 is 4 units.

We can find the points passing through the lines

Hence,

The points passing through the line y = x - 11  are:-

Let x = 11

y = 11 - 11 = 0

(11,0)

and;

Let x = 12

y = 12 -11 = 1

(12,1)

The points passing through the line y = x - 7 are:-

Let x = 7

y = 7 - 7 = 0

(7,0)

and;

Let x = 8

y = 8 -7 = 1

(8,1)

Hence, using distance formula, the distance between the parallel lines will be:-

The foci are placed 4 feet apart from the ellipse's center. Then the distance between the foci of the ellipse will be separated by 8 feet.

Ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.

A major axis of 32 ft and a minor axis of 14 ft.

The major axis 2a of the ellipse will be

2a = 10 feet

a = 5 feet

The minor axis 2b of the ellipse will be

2b = 14

b = 7 feet

We must utilize the following connection to get the foci's coordinate:

b² = a² - c²

3² = 5² - c²

c² = 25 - 9

c² = 16

c = ± 4

As a result, the foci are placed 4 feet apart from the ellipse's center. As a result, the foci are separated by 4 + 4 = 8 feet.

The total number of band members and dancers in the halftime show in all rows were 276.

A row is an arrangement of things in a straight line next to each other.

if there are n rows and each row has m members then total number of members = m* n

Given that marching band was in 3 sections and each section has 8 rows of  8 players , then players in each section of marching band  = 8 *8 = 64

As, there are 3 such sections then total number of marching band players =3*(players in each section) = 3* 64 = 192

Given that there are 2 sections of dancers and each section has 6 rows of 7 dancers.

Then, dancers in each section of  dancers = 6*7 =42

As there are two such sections, then the total dancers = 2* 42 = 84

Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100.

The number 1.23 as a percentage is 123 %.

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The percent sign, %, is frequently used to indicate it. There is no unit of measurement for a percentage. It is a dimensionless number (pure number).

Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.

Let the number be 1.23

To find percentage multiply it by 100, we get

So, 1.23 × 100 = 123 %

Therefore, the number 1.23 as a percentage is 123 %.

The exterior angle (∠ 5) is larger than either remote interior angle (∠ 7 and ∠ 8).

Exterior Angle Inequality Theorem

According to the exterior angle inequality theorem, the measure of any exterior angle of a triangle is greater than the measure of either of the opposite interior angles. The adjacent interior angle and the exterior angle are supplementary. A triangle's exterior angles add up to 360º.

A triangle's exterior angle is always greater than its two remote interior angles.

By the Exterior Angle Inequality Theorem, the exterior angle (∠ 5) is larger than either remote interior angle (∠ 7 and ∠ 8).

The weight of the baby increased by a 20%

We know that the initial weight of the baby is 20 pounds, so that will be our 100%, and we can write:

20lb = 100%

Then the weight is 24 lb, so that will represent another percentage X, we can write:

24lb = X

We can solve this for X, taking the quotient between the relations:

(24lb/20lb)  = X/100%

(24lb/20lb)*100% = X = 120%

So we can see that the weight of the baby increased by a 20%

The missing terms of an arithmetic progression (AP) are -3, 5, 13, 21, 29.

An arithmetic progression (AP) is a pattern in which each successive term has the same distinctions.

The arithmetic sequence.... 5, .. , 21,...

There are total 5 terms in the series.

Let the initial term be 'a₁'.

Let the second term be 'a₂' = 5.

Let the third term be 'a₃'.

Let the fourth term is be 'a₄' = 21.

And final, the fifth term be 'a₅'.

The common difference of the AP are same. so,

d = a₃ - a₂      ........(equation 1)

d = a₄ - a₃  .......(equation 2)

Thus, equate the two formed equation;

a₃ - a₂ = a₄ - a₃

Substituting the values;

a₃ - 5 = 21 - a₃

Simplify the above equation;

a₃ = 26/2

a₃ = 13.

Put the value in equation 1 and find the common difference.

d = a₃ - a₂

d = 13 - 5 = 8

So, the first term will be;

d = a₂ - a₁

a₁ =  a₂ - d

a₁ = 5 - 8

a₁ = -3

Now, the fifth term will be;

a₅ = a₄ + d

a₅ = 21 + 8

a₅ = 29.

Therefore, the arithmetic sequence of the AP formed as -3, 5, 13, 21, 29.

Step-by-step explanation:

Answer:

All answers in explanation

Step-by-step explanation:

Step 1: Unknown
Unknown is the number of refills purchased

Step 2 Key Information
Cost of souvenir cup, price per refill and total money spent

Step 3: Strategy (equation)
Define a variable x that represents the number of refills bought

The souvenir cup cost $14.25

Each refill costs $1.25

So x refills will cost 1.25x

Total cost = 14.25 + 1.25x

We are told she spent $23

So the equation is
14.25 + 1.25x = 23

Step 4: Solution
Equation is
14.25 + 1.25x = 23

a) Isolate the x term by subtracting 14.25 on both sides

14.25 - 14.25 + 1.25x = 23 - 14.25

1.25x = 8.75

b) Divide both sides by 1.25:
1.25x/1.25 = 8.75/1.25

x = 7

Solution is 7 refills

Step 5: Check your answer
Plug x = 7 back into the left side of the equation and check if it works out to 23
14.25 + 1.25 (7) = 14.25 + 8.75 = 23

So our answer is correct

The 17 th term of the Arithmetic Progression (AP) is found to be a₁₇ = 26.

In Arithmetic Progression (AP), the difference between the two numerical orders is a constant value. Arithmetic Sequence is another name for it.

We'd come across a few important words in AP, denoted as:

The AP may also be characterized in concepts of common distinctions, as shown below.

Now, as per the given data in the question;

16th term; a₁₆ = 18

Common difference; d = 5

Then, the 17th term would be calculated as;

Use the common difference formula;

d = a₁₇ - a₁₆

a₁₇ = a₁₆ + d

a₁₇ = 21 + 5

a₁₇ = 26

Therefore, the value of the 17th term of a AP is found as 26.
