Answer:
lowest : 15 $ (at April 2014)highest : 150 $ (at February 2014)The second H-shaped polygon is a scaled copy of the first. The height of the original H is 5 units. The width is 10. The center bar is 4 across. The height of the copy is about 1.25 units. The width is about 2.5. The center bar is 1 across. Show one pair of corresponding points and two pairs of corresponding sides in the original polygon and its copy. Consider using colored pencils to highlight corresponding parts or labeling some of the vertices. What scale factor takes the original polygon to its smaller copy? Explain or show your reasoning.
Answer:
a. See attachment 2
b. Scale factor is 1/4
Step-by-step explanation:
See attachment 1 for complete question
Given
Original
[tex]Height = 5[/tex]
[tex]Width = 10[/tex]
[tex]Center = 4[/tex]
Scaled Copy
[tex]Height = 1.25[/tex]
[tex]Width = 2.5[/tex]
[tex]Center = 1[/tex]
Solving (a): Corresponding Points & Sides
The corresponding points of the original copy to the scaled copy can be gotten by writing out the measurements as : (x,y)
Where x represents the original and y represents the scaled copy
Taking the height as a point
We have:
[tex]Height: (5,1.25)[/tex]
This will be represented as a dot or point.
A dot at the tip of the line representing height in the original and scaled copy can be colored green
And the width and center as sides
We have:
[tex]Width: (10,2.5)[/tex]
[tex]Center = (4,1)[/tex]
These will be represented by lines
For width:
Two lines representing width in the original and scaled copy respectively can be colored yellow
For center:
Two lines representing center in the original and scaled copy respectively can be colored red
See attachment
Solving (b): The scale factor
To solve for the scale factor, we simply divide the measurement of the scaled copy by the original copy
Recall that:
[tex]Height: (5,1.25)[/tex] , [tex]Width: (10,2.5)[/tex] and [tex]Center = (4,1)[/tex]
Using Height:
[tex]Scale\ Factor = \frac{1.25}{5}[/tex]
This gives:
[tex]Scale\ Factor = \frac{1}{4}[/tex]
For width:
[tex]Scale\ Factor = \frac{2.5}{10}[/tex]
This gives:
[tex]Scale\ Factor = \frac{1}{4}[/tex]
For the center:
[tex]Scale\ Factor = \frac{1}{4}[/tex]
Hence, the scale factor is 1/4
Stacy was sitting in a seat at a football game when another ticket holder told her she was in the wrong seat. The other ticket holder politely told Stacy she needed to go 2 rows up and 4 seats to the left. Which rule describes the translation needed to put Stacy in the correct seat?
1. (x, y)--->(x – 4, y + 2)
2. (x, y)--->(x – 2, y + 4)
3. (x, y)--->(x + 4, y – 2)
4. (x, y)--->(x + 2, y – 4)
Answer:
1
Step-by-step explanation:
So it has to be positive 2 because its going up not down and its going left making it negative 4 and up is the y value and left is the x value

find two numbers whose sum is 27 and product is 365
Answer:
There are no real number solutions to this.
Step-by-step explanation:
x + y = 27
xy = 365
y = 365/x
x + 365/x = 27
x^2 + 365 = 27x
x^2 - 27x + 365 = 0
x = [27 +/- sqrt(27^2 - 4 * 1 * 365)] / 2
x = (27 +/- sqrt (-731)/2
- No real roots.

10x - (2x + 9) = -3 (15 - 4x)
Answer:
x=9
Step-by-step explanation:
First, distribute the negative sign, changing (2x+9) to -2x-9
next, distribute. 10x+−2x+−9=(−3)(15)+(−3)(−4x)
then, combine like the like terms (10x+−2x)+(−9)=12x−45
then you get 8x+−9=12x−45, and you will subtract 12x from both sides, resulting in −4x−9=−45. To get -4x by itself, add 9 to both sides
lastly, divide both sides by -4
x=9
Answer:
x = 9
Step-by-step explanation:
Distribute
10x - (2x + 9) = -3 (15 - 4x)
10 − 2 − 9 = − 3 (15 − 4)
Combine like terms
8 − 9 = − 3 (15 − 4 )
Rearrange terms
8 − 9 = − 3 (− 4 + 15)
Distribute
8 − 9 = 12 − 45
Add 9 to both sides of the equation
8 − 9 + 9 = 12 − 45 + 9
Translate this phrase into an algebraic expression. 63 decreased by twice Carlos's height Use the variable c to represent Carlos's height.
Answer:
63-2c
Step-by-step explanation:
You write 63 and substitute decreased with a subtraction sign. Twice means to multiple by 2. so for twice of Carlo's height you would write 2c.

Write the obese equation in slope intercept form
Slope= 1; y intercept = -4
Answer:
y = x - 4
Step-by-step explanation:
In y = ax + b form, a is the slope and b is the y intercept so a = 1 and b = -4, thus y = x - 4
So, this is pretty simple. First, we need to know that slope intercept form is y=mx+b, m equals slope and b equals y intercept. Thus, the equation will be y=1x-4. When you have a positive number as your y intercept then it would have a + after mx but, since we have a negative number here it will have a - after mx.

The bakers at Healthy Bakery can make 350 bagels in 5 hours. How many bagels can they bake in 20 hours? What was that rate per hour? SHOW WORK, ITS RATIOS!!
Step-by-step explanation:
It is given that,
The bakers at Healthy Bakery can make 350 bagels in 5 hours.
We need to find how many bagels can they bake in 20 hours.
In 5 hour = 350 bagel
In 1 hour = 70 bagel
To find no of bagel in 20 hours, multiply 20 by 70 as follows :
In 20 hours = 70×20
= 1400 bagels
So, 1400 bagels can they bake in 20 hours. Also, the rate per hour is 70 bagel/hour.

She took the amount that she spent on the canvas, frame, and supplies, and marked up the price by 115%. How much did she charge for her
painting? Round to the nearest cent.
9514 1404 393
Answer:
$342.37
Step-by-step explanation:
When a quantity is marked up by x%, its marked-up price is (1 +x/100) times its original price. Tax is effectively a markup.
Louise's costs are ...
$125 + (12.50 +19.50)(1.07) = $159.24
Louise priced her painting at ...
$159.24·(1 +1.15) = $342.37

Answer:

The value of the inequality equation is x ≥ - 3 1/2
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be A
Now , the value of A is
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
The value of x ≥ - 3 1/2
On simplifying the equation , we get
The value of x ≥ -7/2
Now , converting the number into decimal form , we get
The value of x ≥ -3.5
So , the number x satisfies for all the values that are above -3.5
Therefore , the value of x is greater than all the numbers greater than -3.5
And the graph for x ≥ -3.5 is given below
Hence , The value of the inequality equation is x ≥ - 3 1/2

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling. Abha collected 178more cans than Shane did.
Answer:
Shane collected 911 cans.
Step-by-step explanation:
S - represents Shane
S + (S + 178) ≥ 2000
2S + 178 ≥ 2000
*subtract 178 from both sides*
2S ≥ 1822
