What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

It is given that a TV programme begins at 7:45 p.m. and ends 50 minutes later.

Addition is one of the fundamental mathematical operations we utilize on a daily basis. We employ addition of numbers in a variety of contexts. Working with time or money, such as adding up bills and receipts, is one of the most frequent daily uses for adding numbers.

We have to apply the addition operation by splittiong the time as,

=7:45 p.m + 50 minute

=7:45 p.m + 15 minute + 35 minute

=8:00 pm + 35 minute

=8:35 pm

Thus, a TV programme begins at 7:45 p.m. and ends 50 minutes later.At 8:35 pm time it will finish.

Maria has purchased a basic stained glass kit for $100. She plans to make stained glass suncatchers and

with a rational function that gives the average cost of a stained glass suncatcher when the cost of the kit
is included in the calculation. Use the graph of the function to determine the minimum number of
suncatchers that brings the average cost below $22.50.
The minimum number of suncatchers that brings the average cost below
$22.50 is

Answers

Answer:

Step-by-step explanation:

fixed cost = 100

variable cost = 13

soooo....

cost =  (13x + 100)/x

the questions wants to know  when cost  < 22.50

22.5 > (13x+100)/x

look at graph attached ;)

it looks to me like it's at 11

22.5 > (13(11) + 100) / 11

22.5 > 22.09

try 10

22.5 > (13(10) +100)/10

22.5  > 23   not true  so yes.. 11 is when the cost goes below 22.50

Answers

Answer:

15 units

Step-by-step explanation:

ΔADC is an isosceles triangle because it has 2 equal sides

AB = BC       (DB is median so cuts AC into 2 equal parts)

AB = 5x, BC = 4x + 3

      5x = 4x + 3

5x - 4x = 4x - 4x + 3          (subtracting 4 from both sides)

        x = 3

AB = 5x

     = 5(3)

Answer:

x = 70

Step-by-step explanation:

The 2 given angles are same- side interior angles and are supplementary, that is sum to 180° , then

45 + 2x - 5 = 180, that is

2x + 40 = 180 ( subtract 40 from both sides )

2x = 140 ( divide both sides by 2 )

x = 70

To most, he is known simply as Picasso. He was born on October 25th, 1881, and died on April 8, 1973. Pablos father was a drawing teacher, and he encouraged his sons artistic ability. When Pablo was ten years old, the family moved to Barcelona, Spain, where Pablo took an exam to enter a famous and prestigious art school, called La Llonga. The exam was supposed to take one month, but Pablo finished it in one day! He later moved to Paris, where was worked as an artist creating and exhibiting his drawings. During this time, he created his famous Blue Period works. They were called this because of their devotion to the color, and because they were quite somber in nature. In 1907, Picasso painted Les Demoiselles dAvignon, which is known to have been the first painting in the modern art movement. Artists from all over the world travelled to see this painting. Picasso created cubism, with a colleague named George Braque In the 1920s, Picasso continued his work by creating theatre sets. His work during this period was considered neo-classical, modern, surreal, and cubist. In 1937, there was a terrible bombing in a small Spanish town called Guernica. Picasso reacted by creating one of his most famous murals, a masterpiece named after the town of Guernica. Picasso then moved on to print making and lithography. He was never content to use a medium the way it was traditionally used, and came up with many inventive new ways to create art. He worked on etchings, engravings, and worked on many other techniques. Just before his 87th birthday, he completed a series called the 347 Series, in which he created three hundred and forty seven pieces of etching and engraving work between March and October! One of the most interesting things about Picasso is that he was the first artist to be famous during his own lifetime. He was quite a celebrity, and is considered one of the most important artists of the twentieth century.
