a counter clockwiswe rotation of 360
A counterclockwise rotation of 360° maps an image onto itself.
What is a coordinate transformation?Suppose the initial coordinates are (x₁,x₂). We do 4 kinds of operations on the coordinates which include:
the translation which means to move the coordinate up and downdilation which means to expand or contract the length of the coordinate from the originrotation which means to rotate the coordinate about the origin counterclockwise or clockwise. The reflection which means to reflect the coordinate about the x-axis or y-axis.After doing these operations the final position of the coordinates is called the transformation of the initial coordinate.
How to solve it?On a counterclockwise rotation of 360 degree the coordinate comes back to the original position.

Reese has a greenhouse and is growing daisies. The table shows the average number of sunflowers that bloomed over four months:
Month 1 2 3 4
Daisies 10 13.1 16.2 19.3
Did the number of daisies increase linearly or exponentially?
Linearly, because the table shows a constant percentage increase in daisies each month
Exponentially, because the table shows that the daisies increased by the same amount each month
Linearly, because the table shows that the daisies increased by the same amount each month
Exponentially, because the table shows a constant percentage increase in daisies each month
Answer:
linearly because the table shows that the daisies increased by the same amount each month
Step-by-step explanation:
Answer:
Linearly, because the table shows that the daisies increased by the same amount each month
Step-by-step explanation:
Take the second term and subtract the first term for the output
13.1 -10 = 3.1
Do the same for the third and the second
16.2 -13.1 = 3.1
And the fourth and third
193. -16.2 = 3.1
This is a linear increase since we add the same amount each time

Answer:
26
Step-by-step explanation:
Let x represent the missing number
[tex] 8\frac{11}{15} = 7\frac{x}{15} [/tex]
Convert both fractions to improper fractions
[tex] \frac{131}{15} = \frac{105 + x}{15} [/tex]
Cross multiply
[tex] 15(105 + x) = 15(131) [/tex]
[tex] 1,575 + 15x = 1,965 [/tex]
Subtract both sides by 1,575
[tex] 15x = 1,965 - 1,575 [/tex]
[tex] 15x = 390 [/tex]
Divide both sides by 15
[tex] x = \frac{390}{15} [/tex]
x = 26

Check the picture below.
so we know the radius of the semicircle is 2 and the rectangle below it is really a 4x4 square, so let's just get their separate areas and add them up.
[tex]\stackrel{\textit{area of the semicircle}}{\cfrac{1}{2}\pi r^2}\implies \cfrac{1}{2}(\stackrel{\pi }{3.14})(2)^2\implies 3.14\cdot 2\implies 6.28 \\\\\\ \stackrel{\textit{area of the square}}{(4)(4)}\implies 16 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{\textit{sum of both areas}}{16+6.28=22.28}~\hfill[/tex]
Two classmates have decided to read all the volumes in a popular series of books. Carly has
already read 10 volumes and will continue to read new ones at a rate of 2 volumes per week.
Lisa, who hasn't started reading the series yet, will read 4 volumes per week. At some point,
Lisa will catch up with Carly and they will be reading the same book. How many volumes will
each girl have read by then? How long will that take?
Answer:
the volumes they would have read is 20
so it will take them 5 weeks
Step-by-step explanation:
C ( started with 10) < 12<14<16<18<20 =5 weeks
L (started with 0) <4 <8<12<16<20 = 5 weeks
for them to read the same book will take them 5 weeks and each of them would have read 20 volumes by then

Solve for x if ab ≠ 2c
[tex]x = \frac{ac + b}{2c - ab} [/tex]
Refer to the attachment for step by step explaination.
Answer:
[tex]x=\frac{b+ax}{2c-ba}[/tex]
Step-by-step explanation:
When given the following expression, one is asked to solve for (x):
[tex]\frac{2x-a}{b}=\frac{ax+1}{c}[/tex]
Use cross products to rid the variable in the denominator,
[tex]c(2x-a)=b(ax+1)[/tex]
Simplify, distribute, multiply every term in the parenthesis by the term outside of it,
[tex]2xc-ac=bax+b[/tex]
Inverse operations, collect all terms with variable (x) on one side of the equation:
[tex]2xc-ac = bax + b\\\\2xc - bax = b + ac[/tex]
Factor, remove a like term that exists in both of these expressions,
[tex]x(2c-ba)=b+ax[/tex]
Inverse operations,
[tex]x=\frac{b+ax}{2c-ba}[/tex]

so you would do -81x(-3) which equals 243.
Will appreciate it :)
Answer:
Step-by-step explanation:
In order for lines to be parallel they have to have the same slope. The first 2 equations there are solved for 5y, so let's do that to the last one--solve it for 5y--and put them all in the same order (the order that the first one is in; they will all look identical then). Equation #2 in the same order as in #1: 5y = 3x - 4. Equation #3 then becomes 5y = 3x - 1. Equations #2 and 3 have the same slope.

To solve this problem I multiplied $9.50 x 168 to figure out how much it would cost to feed the lambs. Unfortunately my answer, $1596, was incorrect. How would I solve this type of problem?
===========================================================
Explanation:
That calculation you wrote out would only apply if each lamb ate 1 full bale of alfalfa.
Instead, each lamb eats 1/8 of a bale. So you'll divide the 1596 value by 8 to get 1596/8 = 199.50
This is the same as saying (1/8)*1596 = 0.125*1596 = 199.50
---------------------
Or we can think of it like this
1 day = 1/8 bale of alfalfa
168*(1 day) = 168*(1/8 bale of alfalfa)
168 days = 21 bales of alfalfa
This says that one lamb will eat 21 bales of alfalfa over the course of 168 days
At $9.50 per bale, the total cost for one lamb is 9.50*21 = 199.50 dollars
This cost applies to one lamb only. So if you had say 3 lambs overall, then you'd multiply that by 3.

find the value of x (URGENT/GIVING BRAINLIEST)
Answer:
B)10
Step-by-step explanation:
Because this is a right angle(indicated by the red box) the total measure should be 90°.
And based on that we say 5X +40=90
Subtract 40 from both sides to get 5x=50
And then divide both sides by 5 to get x=10
Answer:
x = 10°
Step-by-step explanation:
5x° + 40° = 90°
5x° = 90°-40°
5x°=50°
x°= 50°/5
x = 10°

OPTION D is the correct answer
Perimeter of 30 ft in an area of 14 ft what is the length and the width
Answer:
14 and 1
Explanation:
14 + 14 + 1 + 1 = 30
14 x 1 = 14
The perimeter is the sum of all 4 sides. Divide the perimeter in half fo the some of one length and one width:
Length + width = 15
Area is length x width
Find 2 numbers that when added equal 15 but when multiplied equal 14
15 + 0 = 15, 15 x 0 = 0
14 + 1 = 15, 14 x 1 = 14
The answer is 14 ft long by 1 ft wide
Whats 5x=234 please answer i will brainliest if i can
Answer:
x = 46.8
Step-by-step explanation:
I assume you are trying to find the value of x.
[tex]5x=234.[/tex]
To find x, divide the answer by the coefficient. The quotient is the value of 'x.'
[tex]234/5=46.8[/tex]
Therefore, 46.8 is the value of x.
Remember: Whenever you see a coefficient and a variable together—5x, 7y, 3t—this means to multiply them.

Answer:
D-780 squared inches
Step-by-step explanation:
you multiply 2(l)(w)+2(l)(h)+2(w)(h)
Answer:
Last option 780.
Step-by-step explanation:
To get the surface area for this you will need to get the area of each square that you see is in the net version. Once you do that you add them all together. Here is the math. . .
(4*25)+(4*10)+(4*25)+(10*25)+(10*25)+(4*10) = 780 total surface area.
If this looks confusing just look at the net version of the rectangular prism and you can see there is a duplicate of the different dimension triangles. These areas would be (4*25), (4*10), (10*25). There are a total of 3 different size triangles and all of them have duplicates. So we just multiply everything by 2
(4*25)+ (4*10)+(10*25) = 390 now multiply that by 2 and you get 780 again.
Hope the explanation helps :)
