Remark
Draw a line across the east and west farthest points. If you count the lower left point as 0,0, I am talking about 1,6 and 7,6 What that does is divide the figure into a triangle and a trapezoid.
Triangle
The base goes from x = 1 to x = 7 when that new line is introduced which is 6 units parallel to the x axis.
The height goes from 4,4 to 4,6 which is 2 units in the y direction.
So the area = 1/2 (2)*(6) = 6 units.
Trapezoid.
h = 3 derived from 4,3 to 4,6 which is 3 points 6 - 3 = 3
b1 = 6 That's the line you just drew in.
b2 = 4 That comes from 2,3 to 6,3 6-2 = 4
Area = 1/2 (b1 + b2) * h
Area = 1/2 (6 + 4)* 3
Area = 5 * 3 = 15
Total Area = 15 + 6 = 21

By selling an article for rs 660 pradeep loses 60 rs at what price he must sell the article to gain 15%
Answer:
828 rs
Step- -step explanation:
pradeep sold the item for 60 rs less than the cost price
The cost price = amount lost + amount it was sold
60 + 660 = 720 rs
To determine the selling price that would yield a gain of 15%,
calculate 15% of 720. Add the amount derived in the above step to 72015/100 x 720 = 108
108 + 720 = 828 rs

George solved the following system of equations using substitution.
y = 4.3 – 21
12x – 3y = 63
He decided there is no solution. After the following steps:
y= (4x – 21)
12x - 3(4x – 21) = 63
12:- 12.c + 63 = 63
63 = 63
Is George correct in his conclusion? If not choose the correct solution below. If he is correct, select that choice.
A) George is correct with no solution.
B) He is not right. There are infinitely many solutions.
C) He is not right. The solution is (63,63)
Answer:
B
Step-by-step explanation:
-4x + y = -21
12x -3y = 63
-4/12 = -1/3
1/-3 = -1/3
-21/63 = -1/3

In circle H with m \angle GHJ= 34m∠GHJ=34 and GH=11GH=11 units, find the length of arc GJ. Round to the nearest hundredth
Answer:
2.75unitsStep-by-step explanation:
Find the diagram attached
The length of an arc is expressed as shown;
[tex]L = \frac{\theta}{360} * 2 \pi r[/tex]
r is the radius = length of GH
r = GH = 11units
m<GHJ = 34 degree
Substitute the given parameters into the equation given;
[tex]L = \frac{\theta}{360} * 2 \pi r[/tex]
[tex]L = \frac{34}{360} * 2(3.14)(11)\\ L = \frac{34}{360} * 29.08\\L = \frac{988.72}{360}\\L = 2.75 units\\[/tex]
Hence the length of the arc to the nearest hundredth is 2.75units

2) A circle has a diameter of 10 feet. What is the area of the circle, in square feet?
Answer:
Area = 78.5 square feet
Step-by-step explanation:
Formula for area of a circle: A = pi r^2 or area = pi times radius squared
So the diameter = 10 feet
And radius is half of the diameter so radius = 5 feet
A = pi x 5 squared
A = pi x 25
A = 78.5 square feet
Answer:
A = 78.5 [tex]ft^{2}[/tex]
Step-by-step explanation:
A = π[tex]r^{2}[/tex]
diameter = 10
radius is half of 10 = 5
A = 3.14 x [tex]5^{2}[/tex]
A = 3.14 x 25
A = 78.5 [tex]ft^{2}[/tex]

The sides and angles should be the same as the un-reflected version, except everything is flipped, thus the corresponding parts are attached below.
Explanation of how reflection across axis works?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Thus, if we are reflecting a point (x,y) along x axis, then its x abscissa will stay same but y ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if we are reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
The sides and angles should be the same as the un-reflected version, except everything is flipped, thus the corresponding parts are attached below.

A rectangular billboard is 9.35 meters wide and 6.82 meters tall. What is the perimeter of the billboard in meters?
Answer:
32.34 meters
Step-by-step explanation:
All you need to do is label the rectangle with the information given. 9.35 for width, and 6.82 for length.
Next, just fill in the other sides and add. Because it's a rectangle, then you should be able tp label the blank sides.
Next, just add all the sides together and then you'll get your perimeter!
9.35 + 9.35+ 6.82 + 6.82= 32.34
Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels
The question is incomplete:
Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels? The table that shows the types of bagels sold at the bagel shop on Friday is attached.
a. $70
b. $20
c. $90
d. $110
Answer:
c. $90
Step-by-step explanation:
First, you need to find the amount of bagels that Sasha purchased. The statement indicates that she buys all the chocolate chip bagels and the table shows that 28 chocolate chips bagels were sold, so that's the amount she purchased of this type of bagels. Also, the statement indicates that she buys half of the plain bagels and the table says that 16 plain bagels were sold, so you have to divide this amount by 2:
16/2=8
Then, you have to add the amount of chocolate chips bagels plus the amount of plain bagels that Sasha purchased:
28+8=36
Now that you know the amount of bagels that Sasha purchased, you have to multiply this for 2.50 that is the price per bagel:
36*2.50=90
According to this, the answer is that Sasha spends $90 on bagels.

He needs to sell 72 more bags.
Step-by-step explanation:
Cho has sold 28 bags and his goal is to sell 100 bags write an inequality to show how many more bags he needs to sell
Let x represent the number of bags he needs to sell
28 + x ≤ 100

A rectangle has a width represented by the expression-2x+20. The length of the rectangle is 6 more than twice the width. Which expression represents the area of the rectangle?
The perimeter of a rectangle is given by:
[tex]\boxed{\bold{Perimeter = 2 (length + width)}}[/tex]
In the problem we have these data:
Length = a Width = -2x + 20 Perimeter = 6 + 2 (-2x + 20)
We replace the data in the equation of the perimeter:
6 + 2 (-2x + 20) = 2 (a - 2x + 20)
We apply distributive property:
6 - 4x + 40 = 2a - 4x + 40
6 = 2a
6 ÷ 2 = a
3 = a
⇒ Length = 3
The area of the rectangle is given by:
[tex]\boxed{\bold{Area = 2 (length + width)}}[/tex]
We have these data:
Length = 3 Width = -2x + 20
We replace the data in the equation of the area:
Area = (3) (- 2x + 20)
We apply the distributive property and obtain:
Area = -6x + 60
The expression representing the area of the rectangle will be -6x + 60

An equilateral triangle with side length 9 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.
Question:-
Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.
_______________________________________________
Solution:-
In an equilateral triangle all sides are equal.
Let s = side length = 9 cm
Then, area of equilateral triangle is given as:
A = (√3/4)s²
Putting the value of s here,
A = (√3/4) * (9 cm)²
=> A = (√3/4) * 81 cm²
=> A = √3 * 20.25 cm²
We know that, √3 = 1.732
=> A = 1.732 * 20.25 cm²
=> A = 35.073 cm²
Rounding to one decimal place,
=> A = 35.1 cm²
_______________________________________________
The answer is 35.1 cm².
