Describe two methods that can be used to find the area of the composite figure.
Answer:
Reason 1: To find the area of a composite figure or other irregular-shaped figure, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.
Reason 2: To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.

The number of DVD's sold at Fry's Electronics in a month was 920 and the number of DVD's sold decreased by 12 per month. The number of Blu-ray discs sold at Fry's Electronics in the same month was 502 and the number of Blu-ray discs sold increased by 26 per month. Write a system of equations to model th situation. If this trend continues, in how many months will the number of DVD's sold each month equal the number of Blu-ray discs sold each month? How many each disc is sold in that month?
Answer:
a) 11 months
b) 788 discs
Step-by-step explanation:
Let us represent number of months = x
For DVD's
The number of DVD's sold at Fry's Electronics in a month was 920 and the number of DVD's sold decreased by 12 per month.
Hence:
920 - 12x
For Blu ray
The number of Blu-ray discs sold at Fry's Electronics in the same month was 502 and the number of Blu-ray discs sold increased by 26 per month.
502 + 26x
Write a system of equations to model th situation.
a).If this trend continues, in how many months will the number of DVD's sold each month equal the number of Blu-ray discs sold each month?
To solve this:
DVD's = Blu-ray
920 - 12x = 502 + 26x
Collect like terms
920 - 502 = 26x + 12x
418 = 38x
x = 418/38
x = 11 months
b) How many each disc is sold in that month?
For DVD's
920 - 12x
x = 11
Hence:
920 - 12 × 11
= 920 - 132
= 788 discs
For Blu ray
= 502 + 26x
x = 11
Hence:
= 502 + 26x
= 502 + 26 × 11
= 788 discs
Therefore, 788 discs were sold in each month

(Please only answer if you know how to solve it and maybe know an app, don't answer just because you want the points.)
Answer:
width= 4
hieght- 5.65
Step-by-step explanation:
so first lets find the diestnce between 0,0 and 4,4
which is 4 root 2
which is approciamitlty 5.65 and this would be the hieght
the width would be 22.64/5.65= approxiamitly 4

Suppose cos(x)=-1/3, where pi/2≤x≤ pi. What is the value of tan(2x)?
Answer:
4√2/7
Step-by-step explanation:
Suppose cos(x)=-1/3, where pi/2≤x≤ pi
tan(2x) = sin(2x)/cos(2x)
Since sin2x = 2sinx cosx
cos 2x = 2cos²x-1
Substitute
tan(2x) = 2sinx cosx/ 2cos²x-1
Given cosx = -1/3
adjacent = -1
hyp = 3
opp = √3²-(-1)²
opp = √9-1
opp = √8
sinx = opp/hyp
sinx = √8/3
tan(2x) = 2sinx cosx/ 2cos²x-1
tan(2x) = 2(√8/3)(-1/3)/ 2(-1/3)²-1
tan2x= (-2√8/9 )÷ (2/9 - 1)
tan2x = -4√2/9 * 9/-7
tan 2x = 4√2/7

in 2010, the price of a laser printer was $1599. in 2018, the price of the same type of printer had dropped to $579. find the percent of decrease. round to the nearest percent
Hi there!
nearest percentage=64%
1.Subtract starting value and final value:
[tex]1599-579=1020[/tex]
2.Divide it by the starting value:
[tex]1020*1599= 0.6378986866791744840525328330206378986[/tex]
3.Multiply the term by 100:
[tex]0.6378986866791744840525328330206378986[/tex]·[tex]100= 63.78986866791744840525328330206378986[/tex]
4.Round the term:
[tex]63.78986866791744840525328330206378986=64[/tex]
Therefore, the decrease of the total 8 years was 64%.
Answer:
64%
Step-by-step explanation:
579 is a 63.789868667917% decrease of 1599.
Percentage of decrease = |1599 - 579|/1599 = 1020/1599 = 0.63789868667917 = 63.789868667917%
What is AE?
Enter your answer in the box.
Answer:
(2x+6)/10 = (x+6)/8
10(x+6) = 8(2x+6)
10x + 60 = 16x + 48
6x = 12
x = 2
so
AE = 2(2) +6
AE = 4 + 6
AE = 10

(9x + 5) and (12x - 19) are one angle split equally.
(9x + 5) = (12x - 19)
The value of m∠BDC is 65°
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles are equal to 180 degrees.
We have,
(9x + 5) and (12x - 19) are one angle split equally.
So,
9x + 5 = 12x - 19
We will solve for x.
9x + 5 = 12x - 19
Add 19 on both sides.
9x + 5 + 19 = 12x
Subtract 9x on both sides.
24 = 12x - 9x
24 = 3x
Divide both sides by 3.
24/3 = x
x = 7
Now,
The value of m∠BDC.
= 12x - 19
= 12 x 7 - 19
= 84 - 19
= 65°
Thus,
The value of m∠BDC is 65°

Step-by-step explanation: The earliest fractions were reciprocals of integers: ancient symbols representing one part of two, one part of three, one part of four, and so on.[28] The Egyptians used Egyptian fractions c. 1000 BC. About 4000 years ago, Egyptians divided with fractions using slightly different methods. They used least common multiples with unit fractions. Their methods gave the same answer as modern methods.[29] The Egyptians also had a different notation for dyadic fractions in the Akhmim Wooden Tablet and several Rhind Mathematical Papyrus problems.[citation needed]
The Greeks used unit fractions and (later) continued fractions. Followers of the Greek philosopher Pythagoras (c. 530 BC) discovered that the square root of two cannot be expressed as a fraction of integers. (This is commonly though probably erroneously ascribed to Hippasus of Metapontum, who is said to have been executed for revealing this fact.) In 150 BC Jain mathematicians in India wrote the "Sthananga Sutra", which contains work on the theory of numbers, arithmetical operations, and operations with fractions.
A modern expression of fractions known as bhinnarasi seems to have originated in India in the work of Aryabhatta (c. AD 500), Brahmagupta (c. 628), and Bhaskara (c. 1150). Their works form fractions by placing the numerators (Sanskrit: amsa) over the denominators (cheda), but without a bar between them. In Sanskrit literature, fractions were always expressed as an addition to or subtraction from an integer. The integer was written on one line and the fraction in its two parts on the next line. If the fraction was marked by a small circle or cross, it is subtracted from the integer; if no such sign appears, it is understood to be added.
Two numbers are in the ratio 4: 5
One of the numbers is 60
There are two possible values for the other number.
What are the two possible values?
Answer:
48 and 75
Step-by-step explanation:
Given data
We are given that the ratio is 4:5
we have two numbers, the bigger and the smaller number
case one: bigger= 60
the smaller is
4/5= x/60
5x= 60*4
5x= 240
x= 48
case two: smaller number = 60
4/5=60/x
4x= 60*5
4x= 300
x= 300/4
x= 75
Hence the two possible numbers are 48 and 75
