Answer:

Step-by-step explanation:

first we need to know that redious isn't gien

so we have to find redious

according to Pythagoras theorem

a²+b²=c²

a=√c²-b²

a=17²-15²

a=√(17+15)(17-15)

a=√64

a=8

Hello again! Both D and B are rectangles.

Step-by-step explanation:

You know that a rectangle has 4 sides like a quadrilateral but it is different. Both of the oppiosite sides are the same length. C would not be one because it is not connected therefore it is not a full shape. Because of  A´s even sides, A is not a rectangle. I hope this helps! :]

Step-by-step explanation:

[tex]We\ are\ given\ that:\\AB\ is\ a\ Line\ Segment\ that\ has\ Points\ A\ and\ B,\ that\ are\ it's\ two\ End-Points.\\Now,\\Point\ C\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AC\ and\ CB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:2.\\\\Point\ E\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AE\ and\ EB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:3.\\\\Point\ D\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AD\ and\ DB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:4.\\\\[/tex]

[tex]Now,\\For\ Point\ C,\\Total\ no.\ of\ parts=1+2=3\\Length\ of\ AC=\frac{1}{3}x\\Length\ of\ CB=\frac{2}{3}x\\\\For\ Point\ E,\\Total\ no.\ of\ parts=1+3=4\\Length\ of\ AE=\frac{1}{4}x\\Length\ of\ EB=\frac{3}{4}x\\\\For\ Point\ D,\\Total\ no.\ of\ parts=1+4=5\\Length\ of\ AD=\frac{1}{5}x\\Length\ of\ DB=\frac{4}{5}x\\[/tex]

[tex]Now,\\Lets\ move\ onto\ some\ REAL\ calculations!!\\We\ firstly\ observe\ that,\\AD+DC=AC\\Hence,\\\frac{1}{5}x+DC=\frac{1}{3}x\\DC=\frac{1}{3}x-\frac{1}{5}x\\DC=\frac{5-3}{15}=\frac{2}{15}[/tex]

[tex]We\ secondly\ observe\ that,\\AD+DE=AE\\Hence,\\\frac{1}{5}x+DE=\frac{1}{4}x\\DE=\frac{1}{4}x-\frac{1}{5}x\\DE=\frac{5-4}{20}=\frac{1}{20}[/tex]

Answer:

Total number of loaves of bread sold in [tex]4[/tex] hours is [tex]120[/tex] and [tex]40[/tex] loaves of bread will remain unsold.

Step-by-step explanation:

Given: A bakery produces [tex]2[/tex] batches of bread with [tex]80[/tex] loaves in each batch.

           It sold [tex]30[/tex] loafs each hour.

To find: How many loaves of bread were sold in [tex]4[/tex] hours? How many loaves of bread were left to sell?

Solution:

Total number of loaves of bread produced [tex]=2 \times 80=160[/tex].

Number of  loafs sold each each hour [tex]=30[/tex].

So, number of loafs sold in [tex]4[/tex] hours[tex]=4 \times 30=120[/tex].

Therefore, number of loaves of bread that were remain unsold [tex]=160-120=40[/tex]

Hence, total number of loaves of bread sold in [tex]4[/tex] hours is [tex]120[/tex] and [tex]40[/tex] loaves of bread will remain unsold.

Answer:

[tex]\huge\boxed{\tt{x = 11 , y = 1}}[/tex]

Step-by-step explanation:

x + y = 12 -------------------------(1)

2x + 5y = 27 --------------------(2)

Multiply (1) by 2

2(x+y) = 12 * 2

2x + 2y = 24 --------------------(3)

Subtract (3) from (2)

2x + 5y - ( 2x + 2y ) = 27 - 24

2x + 5y - 2x - 2y = 3

5y - 2y = 3

3y = 3

Divide 3 to both sides

y = 1

Put y = 1 in (1)

x + 1 = 12

x = 12 - 1

x = 11

So,

x = 11 , y = 1

Math can help you if you ever wanna build a desk in the future;)

Maths can be used in the day-to-day shopping at home groceries and vegetables etc.

Numbers, formulae, and related structures, shapes, and the spaces in which they are contained, as well as quantities and their variations, are all covered in the field of mathematics.

An example of daily life is if you are going to the market to purchase fruits the cost of 1 kg of apple is 200rs but you want to buy 30 rs apple only. Then the amount in kg for the 30rs apple will be calculated by using maths.

200rs apple  = 1 kg

1 rs apple = 1 / 200 kg

30 rs apple = ( 1 x 30 ) / 200

30 rs apple = 0.15 kg or 150 grams

In this way, you will get the exact amount of apple for 30 rupees amount by using mathematics

Therefore, maths can be used in the day-to-day shopping at home groceries and vegetables, etc.

-2x<-12

Multiply both sides by -1 (reverse the inequality right)

Answer:

Step-by-step explanation:

Step one:

given data

A contractor purchases 5 dozen pairs of padded work gloves for $71.40

the unit price will be

total number of gloves

5 pairs

unit cost per glove

=71.40/5

=$14.28 per glove

The estimated cost per pair is

$14.28 per pair

The error is

%Error= real price -estimated /estimated*100

%Error= 14.28-14.28/14.28*100

%Error= 0.0*100

%Error= 0%

Answer:

The percent error is 20%.

Step-by-step explanation:

The general formula is to subtract the actual value from the estimated value, take the absolute value of the difference, divide that answer by the actual value, then multiply it by 100.

So, 20 (estimated) minus 25 (actual) is -5. The absolute value of -5 would be 5, since absolute value is always positive. Divide 5 by the actual value, 25, and you get 0.2. Multiply 0.2 by 100 to get a percent value, and the answer will amount to 20%. Hope this helps.
