Angle WXY underwent a sequence of two rotations around different centers. The original size of WXY is 82°. what is the size of the angle after the sequence of rotations?
Given:
[tex]\angle WXY=82^\circ[/tex]
It underwent a sequence of two rotations around different centers.
To find:
The size of the angle WXY after the sequence of rotations.
Solution:
We know that, rotation is a rigid transformation. It means, the size and shape of the figure remains the same after the rotations. It other words, the figure and its image are congruent after rotation.
So, the measure of angle WXY remains same after the sequence of rotations, i.e.,
[tex]\angle W''X''Y''=82^\circ[/tex]
where, [tex]\angle W'X"Y"[/tex] is the image of [tex]\angle WXY[/tex] after the sequence of rotations.
Therefore, the size of the angle WXY after the sequence of rotations is 82°.

Suppose that you own a compact car
that you bought new for 18,000 dollars.
The value of this particular make of car is
known to depreciate at a rate of 20%
per year.
Define a unit for each quantity in the
worksheet. Then enter a variable for
the time since you bought the car new
Answer:
Depreciation and Written Down Value for first 5 years of purchase is explained.
Step-by-step explanation:
The Car was purchased for $18000 this will be depreciated at a rate of 20% per year.
Declining Method
Year 1
$18,000 * 20% = $3,600 Depreciation
$18,000 - $3,600 = $14,400 Written Down Value WDV
Year 2
$14,400 * 20% = $2,880 Depreciation
$14,400 - $2,880 = $11,520 WDV
Year 3
$11,520 * 20% = $2,304 Depreciation
$11,520 - $2,304 = $9,216 WDV
Year 4
$9,216 * 20% = $1,843 Depreciation
$9,216 - $1,843 = $7,373 WDV
Year 5
$7,373 * 20% = $1,475 Depreciation
$7,373 - $1,475 = 5,898 WDV

What is the slope of this here line?
Answer:
3/5
Step-by-step explanation:
It rose 3 and ran 5 (rise over run)
Express this number in scientific notation. 0.15880.1588
Answer: 1.588×10−1 (The negative one is small on the top right of the 10)
Step-by-step explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:
x = 45
y = 60
Step-by-step explanation:
2x = 90
2x (1/2) = 90 (1/2)
x = 45
3y - 2y = 90
3y - 2(45) = 90
3y - 90 = 90
3y - 90 (+90) = 90 (+90)
3y = 180
3y (1/3) = 180 (1/3)
y = 60
Hope this helps :)

The speed limit in front of the school is 25 miles per hour. This is half the speed of a major street one mile away. What is the speed limit of the major street?
Answer:
50 miles per hour
Step-by-step explanation:
this is because 25 is half of 50.
Answer:
50 mph
Step-by-step explanation: the speed limit in front of the school is 25 mph, and the speed limit on a major street one mile away is double that. 25x2=50.

can anyone please help me with this? i need a step by step explanation please! very appreciated:)
y=5x-9
y=3x+7
Answer:
Step-by-step explanation:
x and y are variables. That means they represent numbers that are unknown. When we solve for x or y, we are trying to find what number the variable represents.
Y is a number that equals both 5x-9 and 3x+7. If it is a number, it can only have one value, so we can say that 5x-9 and 3x+7 have the same value.
In other words, 5x-9 = 3x+7.
Another way of thinking about this step is substitution. y=3x+7, so in the equation y=5x-9, we can replace the y with 3x+7. It will give 3x+7 = 5x-9.
In either case, we have this new equation
5x-9 = 3x+7.
From here it's just simple algebra- subtract 3x from each side
2x -9 = 7
and add 9 to each side
2x = 16
and divide each side by 2.
x = 8.
All these steps work because if two things equal each other, when you do the same thing to both of them (such as add 9), the new values will still equal each other.
Now that we know that x = 8, we can take one of the original equations
y=5x-9
and put 8 in for x.
y=5*(8) -9.
If x represents the value 8, we can obviously switch out x for 8.
Now simplify
y=40 -9
y = 31
Now we know that x = 8 and y = 31.
Answer:
x=8 and y=31
Let's solve your system by substitution.
y=5x−9;y=3x+7
Step: Solve y=5x−9for y:
y=5x−9
Step: Substitute5x−9foryiny=3x+7:
y=3x+7
5x−9=3x+7
5x−9+−3x=3x+7+−3x (Add -3x to both sides)
2x−9=7
2x−9+9=7+9(Add 9 to both sides)
2x=16
2x/2=16/2 (Divide both sides by 2)
x=8
Step: Substitute 8 for x in y=5x−9:
y=5x−9
y=(5)(8)−9
y=31 (Simplify both sides of the equation)
Answer:
x=8 and y=31
