Answer:

[tex]\frac{12}{253}[/tex]

Step-by-step explanation:

So I would start by multiplying all the numbers on

the denominator first ----->

11 x 14 = 154

~~~

14 x 17 = 238

~~~                                    *BASICALLY: FIND THE COMMON DENOMINATOR*

17 x 20 = 340                        (this will be how u add everything at the end)

~~~

20 x 23 = 460

Now your goal is to get all of these numbers to be the same as the denominator so you can add them together at the end (get a common denominator)

**(remember when multipling the top and the bottom numbers, whatever you do to the bottom you must do to the top)**

Answer:

y = x + 16

Step-by-step explanation:

Step 1: Find slope of perpendicular line

Take the negative reciprocal of the 1st line

m = 1

Step 2: Find b

y = x + b

14 = -2 + b

b = 16

Step 3: Write equation

y = x + 16

Answer:

y = x + 16

Step-by-step explanation:

Given the equation y = -x - 1, we see that the slope (the coefficient of the x term) is -1.  A line perpendicular to this one has a slope which is the negative reciprocal of the given equation:   +1.

Using the point-slope formula for the equation of a straight line, we get:

y - 14 = +1(x + 2), or y - 14 = x + 2, or y = x + 16

Answer: $735.49

Step-by-step explanation:

Given, the price of 10 tolas gold bought from American market = $553

Custom duty charge = 20%

VAT = 13%

Custom duty charge = 20% of $553

= 0.20 x 553  [we divide a perecntage to convet it into decimal]

= $110.6

VAT = 13% of $553

= 0.13 x 553

= $71.89

Selling price = Original price +Custom duty charge  + VAT

=  $553+$110.6+ $71.89

= $735.49

Hence, it should be sold at $735.49 .

Answer:

$336

Step-by-step explanation:

Answer:

4² + 5² = x²

Step-by-step explanation:

From the picture, the height of the staircase is:

h = 20 ft -15 ft = 5 ft

And the distance between the staircase and the building is 4 ft.

A right triangle is formed, where the distance between the staircase and the building (4) and the height of the staircase (5) are the legs, and the length of the staircase (x) is the hypotenuse. Using Pythagorean theorem:

4² + 5² = x²

Answer:

6 sq units, 4 sq units, 6 sq units

Step-by-step explanation:

Method:

count dots inside ...(a)

the ones on the border of the polygon and divide by two ...(b)

(a)+(b)-1 = area

use this method for the red, green, and yellow polygons.

Red:

(a): 2

(b): 10/2 = 5

2+5-1 = 6 sq units

Green:

(a): 0

(b): 10/2 = 5

0+5-1 = 4 sq units

Yellow:

(a): 3

(b): 8/2 = 4

3+4-1 = 6 sq units

Answer:

24 coins

Step-by-step explanation:

Start:

first pirate --> 1/2 coins

second pirate --> 3/2 coins

Next:

first pirate --> 1/2 + 3/4 = 5/4 coins

second pirate --> 3/2 - 3/4 = 3/4 coins

Next:

first pirate --> 5/4 - 5/8 = 5/8 coins

second pirate --> 3/4 + 5/8 = 11/8 coins

If 5/8 coins is 15, then 1/8 coins is 3, and 8/8 coins is 24 coins.

Answer:

24 coins

Answer:

(4, 7)     (8, 9)    

(2, 3)     (6, 5)

Step-by-step explanation:

The definition of a parallelogram is a quadrilateral that has two pairs of opposite equal length parallel sides, including equal opposite angle measurements

To simplify the task, we plot the  points on a graph paper for the parallelogram ABCD to get the following points;

B (4, 7)     A (8, 9)    

C (2, 3)     D (6, 5)

The length of the opposite sides AB and CD are;

Length AB = √((9 - 7)² + (8 - 4)²) = √20 = 2·√5

Length CD = √((3 - 5)² + (2 - 6)²) = √20 = 2·√5

The length of the opposite sides AC and BD are;

Length AD = √((9 - 5)² + (8 - 6)²) = √20 = 2·√5

Length BC = √((7 - 3)² + (4 - 2)²) = √20 = 2·√5

The slope of segment AB is (9 - 7)/(8 - 4) = 2/4 =1/2

The slope of segment CD is (5 - 3)/(6 - 2) = 2/4 =1/2

Therefore, since the slopes of segments AB and CD are equal, segments AB and CD are parallel

Similarly, we have;

For segment AD, slope = (9 - 5)/8 - 6) = 4/2 = 2

For segment BC, slope = (7 - 3)/4 - 2) = 4/2 = 2

Therefore, the slopes of segments AD and BC are equal, segments AC and BD are parallel.

Step-by-step explanation:

10a - 41 = 19

10a = 19 + 41

10a = 60

Answer:

a=  6

Step-by-step explanation:

10a - 41=19

+41         +41

10a = 60

÷10    ÷10

a=  6

Answer:

The answer would be A. because AB/EF=BC/DE

Step-by-step explanation:

AB = 2

EF = 5

BC = 1

DE = 2.5

2/5 = 0.4

1/2.5 = 0.4

The equation AB/EF=BC/DE is correct. All of the others are not.

The slope of line segment AC the same as the slope of line segment DF in the figure below because AB/EF = BC/DE.

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

We need to find the proportionality statement for the ratio of the sides of the triangles.

If two triangles are similar, then the corresponding sides are proportional.

ABC ≈ DEF,

Here AB, BC, and AC are corresponding sides of DE, EF, and DF respectively.

Using the definition of similarity we ge

AB = 2

EF = 5

BC = 1

DE = 2.5

2/5 = 0.4

1/2.5 = 0.4

The equation AB/EF = BC/DE is correct. All of the others are not.

Answer:

The found values are:

A = 1/3

B = -8/3

Step-by-step explanation:

We know that general equation is given by:

y = mx + c

where m is the slope and c is a constant.

x + 3y = -5

y = -(1/3)x - 1/3(5)

Slop of the equation is -(1/3). As parallel line have same slope substitute it in the first equation:

Ax + By = 3

By = -Ax - 3

By = (1/3)x - 3

Hence, A = 1/3

Substitute point (-7,2) into the equation:

B(2) = (1/3)(-7) -3

B(2) = -7/3 - 3

B(2) = -16/3

B = -16/6

B = -8/3

Answer:

Option A.

Step-by-step explanation:

The given sequence is  

24, 30, 36, 42, 48, ...

It is an AP. Here,  

First term = 24

Common difference = 30-24 = 6

The given explicit formula for nth term is

[tex]a_n=a_1+(n-1)d[/tex]

where, [tex]a_1[/tex] is first term, d is common difference.

Substitute [tex]a_1=24, d=6 \text{ and }n=500[/tex] in the above formula.

[tex]a_{500}=24+(500-1)(6)[/tex]

[tex]a_{500}=24+(499)(6)[/tex]

[tex]a_{500}=24+2994[/tex]

[tex]a_{500}=3018[/tex]

The 500th term of the sequence is 3018.

Therefore, the correct option is A.

median: 90

mode: 91

mean: 84.2 or round it to 84

Step-by-step explanation:

Let me know if this helps! have a great day! :)

Answer:

a) Median = 91

b) mode = 91

c)Mean 84.2

Step-by-step explanation:

a) Median is the middle term. So, 6th term

Median = 91

b) Mode is the score which occurs more number of times

91 occurs 3 times

Mode = 91

c) Mean= sum of all data's/Number of data's

Answer:

There are 9 llamas.

Step-by-step explanation:

For Billy, we have to find a number that is divisible by four, because he has one group of lambs, and 3 times as many llamas, which gives us 4 groups altogether. The number must be below 10 in order to not go above 17 when Milly's number of animals are included, but above 4 itself in order to reach the target of 17 in the first place.

As you can guess, the only number that fits all the criteria is 8. It's divisible by 4 and below 10, but above 4 itself.

If Billy has three times as many llamas as lambs, then he must have 2 lambs, and 6 llamas, as 2 × 3 = 6.

If we know that Billy has 8 animals, then we also know that Milly must have 9 animals, as 17 - 8 = 9.

We also know that Milly has 3 groups of animals; one group of llamas, and two groups of lambs, meaning we divide the number of animals she has by 3.

9 ÷ 3 = 3.

This tells us Milly has just 3 llamas, because 3 is one group of 9, and 3 × 2 = 6,  because she has twice the amount of lambs.

Billy has 2 lambs and 6 llamas.

Milly has 6 lambs and 3 llamas.

The amount of lambs is irrelevant to our final answer, so we can disregard them and do a final sum of 6 + 3 = 9, which gives us our answer.

Answer:

Billy: Has 4 lots of animals

Milly: Has 3 lots of animals

17 animals in total means that Billy must have 4 lots of 2 (8 animals) and Milly must have 3 lots of 3 (9 animals) So Billy has 6 llamas and Milly has 3, giving 9 llamas in total

Answer:

0.00324 kilometres

Step-by-step explanation:

Remember:

100 centimeters = 1 meter

1000 meters = 1 kilometer

So first, let's add together the meters and centimeters. To do that, we have to convert the meters to centimeters. That would become 300 centimeters, then you add the 24 centimeters to get 324 centimeters. Then, you convert that to kilometers. You can use a calculator for this, but I'll show you how to do this without a calculator. Since 100 centimeters is one meter, and 1000 meters equals to one kilometer, there would be 5 spaces from 324 to our answer, so you move the invisible decimal point 5 spaces to the left, and you get your answer, which is 0.00324 kilometres!
