We could see that the size of both images does not change, so it is not a dilation. The image is not mirrored either, so it is not a reflection. Finally, the image does not seem to change place that much from the preimage, so it should not be a translation, either. That means our answer is a rotation, because the image rotated about 180º.

Answer:
35,694
35,981
35,102
Step-by-step explanation:
If you're using the hundreds place for comparison, it means the digits in higher places are the same, and that digits in the hundreds place are different.
This will be true for any 5-digit number of the form ...
(3)(5)(not 7)(something)(something).
The numbers might have digits to the right of the decimal point, but those are irrelevant, as are the digits in the 10s and 1s places.

Carson is 45 inches tall. Convert his height to feet
Answer:
Step-by-step explanation:
45 / 12 = 3.75
12 inches in a foot.
The conversion of Carson's height from inches to feet is equal to 3.75 feet.
Relation between inches and feet is equal to,
1 foot is equal to 12 inches
To convert inches to feet, you need to divide the number of inches by 12, as there are 12 inches in a foot.
Carson's height in feet can be calculated as follows:
Height in feet = Height in inches / 12
Height in feet = 45 inches / 12
Height in feet = 3.75 feet
Therefore, Carson's height is 3.75 feet.

pls help!!! I will make you brainiest!!!!! what is the rate of change
Answer:
$2.69
Step-by-step explanation:
We can divide the cost in dollars to the gallons of gasoline to find the rate of change.
16.14 / 6 = $2.69
21.52 / 8 = $2.69
24.21 / 9 = $2.69
32.28 / 12 = $2.69
53.80 / 20 = $2.69
This means that each gallon costs $2.69, in other words this is the rate o change.

what is the value of x in the equation 6x-5/2 = 2x+6
Answer:
x= 17/8
Step-by-step explanation:
6x− 5/2=2x+6
Step 1: Simplify both sides of the equation.
6x+−5/2=2x+6
Step 2: Subtract 2x from both sides.
6x+−5/2−2x=2x+6−2x
4x+−5/2=6
Step 3: Add 5/2 to both sides.
4x+−5/2+5/2=6+5/2
4x=17/2
Step 4: Divide both sides by 4.
4x/4=17/2/4
x=17/8

Which point on the number line represents 7 less than 4? How do you know?
The point represent is F.
What is number line?A number line is a visual representation of numbers on a straight line. This line is used to compare numbers that are placed at equal intervals on an infinite line that extends on both sides, horizontally or vertically. As we move towards the right side of a horizontal number line, the numbers increase; as we move towards the left, the numbers decrease.
Given:

14 divided by 2 + 3(4) - (6 1/2 - 3)
Answer:
15.5
Step-by-step explanation:
Original Equation:
14 ÷ 2 + 3(4) - (6.5 - 3)
Do the Parentheses first.
6.5 - 3 = 3.5
Equation:
14 ÷ 2 + 3(4) - 3.5
More Parentheses.
3(4) = 3 ⋅ 4 = 12
Equation:
14 ÷ 2 + 12 - 3.5
Divide.
14 ÷ 2 = 7

Explain some methods of reducing friction between of matyer
Answer:
Step-by-step explanation:
1. Use of lubricants
Lubricants like oil and grease helps to decrease friction by forming a thin film in between different parts of the machine. This film covers up the scratches and bumps on the surfaces of different parts. This reduces interlocking between the two surfaces. Thus reducing the friction.
2. Use ball bearings
Two moving surfaces in a machine are attached by placing small steel balls or steel rollers in between them. This way, the moving parts avoid direct contact and the force of sliding friction turns into rolling friction. Rolling friction is less than sliding friction, in doing so reducing the friction.
3. Polishing
Polishing reduces the unevenness of a surface. This will reduce interlocking between the surfaces.
4. Streamlining
Streamlining is the process where you make a machine in a shape that avoids air and water resistance. This reduces friction because a streamlined object cuts through the water and air molecules.
