Answer:
The orientation of the figure has been changed by 90°, but the points are not all rotated around the same center. Translation is involved.
Step-by-step explanation:
Translation before rotation:
.. translate down 5 units
.. rotate counterclockwise 90° about the origin
Translation after rotation:
.. rotate counterclockwise 90° about the origin
.. translate right 5 units
This can also be accomplished by a double reflection.
.. reflect across the line y=x
.. reflect across the line x=2.5
Or,
.. reflect across the line y=2.5
.. reflect across the line y=x

Answer: 104 yards
Step-by-step explanation:
First and foremost, we need.to know that: 1 yard = 3 feet
Since she wants each balloon string to be 6 feet long and she wants to get 52 balloons. The total feet that is required for the balloon would be:
= 52 × 6
= 312 feet
Then we convert 312 feet to yard. This would be:
= 312 feet / 3 feet
= 104 yards

On number 12 I need hell
Answer:
1,600 dollars
Step-by-step explanation:
The easiest way to solve it is to find the dollar for 1 percent.
Since 480 accounts for 30% of the whole thing, we can do 480 divided by 30 to get 16 as 1 percent. This means that 16 times 100 percent would give us the total money spent, giving us 1,600 as our answer.

Using a graph, table of values, and/or equations solve the following problem.
A sofa and a love seat together costs S351. The sofa costs double the love seat. How much does the love seat cost?
Round and write your answer to the tenths place value. Do not include units
Answer:
[tex]L= 117.0[/tex]
Step-by-step explanation:
Represent the sofa with S and the love seat with L.
So, we have:
[tex]S + L = 351[/tex] --- Total Cost
[tex]S = 2L[/tex]
Required
Determine the value of L
Substitute 2L for S in the first equation.
[tex]2L + L = 351[/tex]
[tex]3L= 351[/tex]
Divide both sides by 3
[tex]\frac{3L}{3}= \frac{351}{3}[/tex]
[tex]L= \frac{351}{3}[/tex]
[tex]L= 117.0[/tex]
Hence, a love seat costs 117.0
Using Graph
See attachment for graph
S is plotted on the y-axis and L is on the x-axis.
The green line represents [tex]S + L = 351[/tex] while the orange line represents [tex]S = 2L[/tex]
When the line of the graph is traced to the x-axis, we have:
[tex]L= 117.0[/tex]
A survey was sent via email to a sample of 200 students at a local school to see what percentage of the students
would like to switch to wearing uniforms. Of the 200 students at the school, only 15 replied to the survey. A margin of
error of 6% was calculated. Which of the following biases is present in this data collection method that cannot be
accounted for through margin of error?

1. Explain why n root a^n= |a| when n is even, but not when n is odd.
Step-by-step explanation:
In the expression a^n, for integer values of n greater than 1, there are n factors. For example, a^2 = a * 2 (2 factors), a^3 = a * a * a (3 factors), etc.
For a non-negative value of a, a^n is non-negative for all values of n.
If a is negative, and n is even, then a^n is non-negative.
If a is negative, and n is odd, then a^n is negative.
|a| is non-negative for all values of a.
sqrt_n(a^n) is negative for negative a and odd n, but |a| is always non-negative, so sqrtn(a^n) cannot equal |a| for odd n.
a) Write down the next two numbers in the following sequence.

A gardener is preparing soil for a flowerbed. The directions call for 2 2 3 cups of fertilizer for every 9 bags of soil. If the gardener is using only 3 bags of soil, how many cups of fertilizer does he need?
Answer: [tex]\dfrac89[/tex] cups of fertilizer is required for 3 bags of soil.
Step-by-step explanation:
Given: For every 9 bags of soil, the number of cups of fertilizers required = [tex]2\dfrac{2}{3}[/tex]
Quantity of fertilizer is proportional to the quantity of soil.
Let x be the number of cup of fertilizer required for 3 bags of soil, then
[tex]\dfrac{x}{3}=\dfrac{2\frac23}{9}\\\\\Rightarrow\ \dfrac{x}{3}=\dfrac{\dfrac83}{9}\\\\\Rightarrow\ x=\dfrac{8}{3\times9}\times3\\\\\Rightarrow\ x=\dfrac89[/tex]
Hence, [tex]\dfrac89[/tex] cups of fertilizer is required for 3 bags of soil.
A farm raises cows and chickens. The farmer has a total of 46 animals. One day he counts the legs of all his animals and realizes he has a total of 156 legs. How many cows does the farmer have?
Answer:
11 cows and 2 chickens
Step-by-step explanation:
The required number of cows x = 30 and chickens is y = 16 .
Given that,
A farm raises cows and chickens.
The farmer has a total of 46 animals.
One day he counts the legs of all his animals and realizes he has a total of 156 legs.
We have to find,
How many cows does the farmer have.
According to the question,
Let, The number of cows = x
And the number of chickens =y.
Then,
The number of cows + The number of chickens = The farmer has a total of 46 animals.
x + y = 46
The cows has 4 legs, and the chickens has 2 legs.
He has a total of 156 legs.
Then,
The number of Cow's legs + The number of chickens legs = The total number of legs farmer have.
4x + 2y = 156
On solving both the equation,
x + y = 46
y = 46 - x
Substitute the value of y in the equation 2.
[tex]4x + 2y = 156\\\\4x + 2(46 - x) = 156\\\\4x + 96 - 2x = 156\\\\2x = 156 - 96\\\\2x = 60\\\\x = \dfrac{60}{2}\\\\x = 30[/tex]
The farmer have 30 cows.
And substitute the value of x in the equation 1,
[tex]x + y = 46\\\\30 + y = 46\\\\y = 46-30\\\\y = 16[/tex]
The farmer have 16 chickens.
Hence, The required number of cows x = 30 and chickens is y = 16 .

Step 1: Simplify both sides of the equation.
2x−13−3x4=562x+−13+−34x=56(2x+−34x)+(−13)=56
(Combine Like Terms)
54x+−13=5654x+−13=56
Step 2: Add 1/3 to both sides.
