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.

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.

A junk drawer at home contains five pens, two of which work . What is the probability that you randomly grab two pens from the drawer and don’t end up with a pen that works? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Answer:
The probability is [tex]P(k) = \frac{4}{25}[/tex]
Step-by-step explanation:
From the question we are told that
The number of pens from the drawer is n = 5
The number of pens that doesn't work is k = 2
The probability that a does not work is
[tex]p = \frac{k}{n}[/tex]
=> [tex]p = \frac{2}{5}[/tex]
The probability that a pen works is
[tex]q = 1- p[/tex]
[tex]q = 1- \frac{2}{5}[/tex]
=> [tex]q = \frac{3}{5}[/tex]
Generally the probability that ending up with a pen that doesn't work is mathematically represented as
[tex]P(k) = p^2[/tex]
=> [tex]P(k) = [\frac{2}{5} ]^2[/tex]
=> [tex]P(k) = \frac{4}{25}[/tex]
The probability that you randomly grab two pens from the drawer and don’t end up with a pen that works is [tex]\dfrac{4}{25}[/tex].
Given information:
The number of pens in the drawer is [tex]n=5[/tex].
The number of pens that doesn't work is [tex]a=2[/tex].
So, the number of pens which works will be, [tex]b=5-2=3[/tex].
The probability of grabbing a pen that doesn't work will be,
[tex]P_a=\dfrac{2}{5}[/tex]
Now, two pens are grabbed randomly from the drawer. So, the probability that you randomly grab two pens from the drawer and don’t end up with a pen that works will be calculated as,
[tex]P=(P_a)^2\\P=\dfrac{2}{5}\times \dfrac{2}{5}\\P=\dfrac{4}{5}[/tex]
Therefore, the value of the required probability will be [tex]\dfrac{4}{5}[/tex].

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

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 ...

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
Equation:
7 + 12 - 3.5
Add.
7 + 12 = 19
