164-64=100 like only cats
(01.05 MC)The total charge on 7 particles is -42 units. All the particles have the same charge.
Answer:
[tex]Unit\ Charge = -6\ units[/tex]
Step-by-step explanation:
Question is incomplete; However, the missing part of the question will most likely be to calculate the charges on each particle.
If that is the case;
[tex]Tota\l Charges = -42\ units[/tex]
We'll get the unit charge when we divide by 7.
This is so because, they all have the same charge.
[tex]Unit\ Charge = -42\ units/7[/tex]
[tex]Unit\ Charge = -6\ units[/tex]
Hence;
the unit charge is -6 units
Answer:
the unit charge is -6 units

The dimensions on a blueprints indicate that 1 inch equals 3.5 feet. If one wall of a room on the blueprint is 6 inches, whats the actual length of the wall
Answer:
21 feetStep-by-step explanation:
The problem bothers on the dimension of a scaled drawing/prototype
The indications on the blueprint actually represent the scale
that is 1 inch: 3.5 feet
Given that a wall is 6 inches on the blueprint, now, in reality, the actual
length will be 3.5*6= 21 feet
what is a scaled drawing?Usually, the scale is given as a ratio. A drawing, which has been reduced or enlarged or a drawing whose dimensions have been changed to a particular size other than its previous or initial size is a scaled drawing.

How do you write fraction for 0.105
Answer:
21/200
Step-by-step explanation:
take .105 and put it over thousand ( 105/1000) then see what number you could divide by to make the fraction smaller (105/1000 ÷ 5) then divide by that number (105/1000 ÷ 5 = 21/200)
There ya go!
Answer:
The answer is 21/200
the lcm and hcf of 84 and 96 pleasee
Answer: LCM=672; HCF=12
Step-by-step explanation:
LCM=Least Common Multiple
HCF=Highest Common Factor
Factor of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
Factor of 96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
From the list we can see, the highest common factor between 84 and 96 is 12.
The easiest way to find least common multiple is to time the numbers together and then divide it by their highest common factor.
84×96÷12=672

In a faraway land, there are 72% white people. There are 30% of people have a particular disease. And if you randomly select a person, that person has 20% chance of being white and have the disease. (a) What proportion of students are non-white and who is healthy? (b) Kelly’s race is white, what is the chance that she has this disease? (c) Are the events of being white and having the disease independent events? (d) If you randomly select 10 people, what is the chance that 2 have the disease?
Answer:
Step-by-step explanation:
Let the probability of people being white be P ( W ) and being diseased
be P ( D )
Given
P ( W ) = .72 , P ( D ) = .3
P ( W∩D ) = .2
a )
P ( [tex]W^c[/tex] ∩ [tex]D^c[/tex] ) = P[tex]( WUD)^c[/tex] = 1 - P ( W U D )
= 1 - [ P( W ) + P ( D ) - P ( W ∩ D ) ]
= 1 - ( .72 + .3 - .2 ) = .18
b )
P ( D / W ) = P ( W∩D ) / P(W) = .2 / .72 = .27778
c )
No , because
P ( W∩D ) = .2
p ( W) x P ( D ) = .72 x .3 = .216
so P ( W∩D ) is not equal to P ( W) x P ( D )
d )
We shall apply binomial distribution

Distance from Starting Point of Spring (inches) 6 2 1 7 Weight on Spring (kilograms) Part A According to the graph, what is the constant of proportionality in kilograms per inch? (Note: This is also called the spring constant. The spring constant is determined by the spring's material and design.)
Answer:
The constant of proportionality is the number of kilograms that will stretch the spring by 1 inch. When y = 1, x = 1/3, so the constant of proportionality in kilograms per inch is 1/3.

Does it matter which two points you start on when calculating slope?
It does not matter which of the two "slope" formulas you use, nor does it matter which point you pick to be your "first" and which you pick to be your "second". The only thing that matters is that you subtract your x-values in the same order as you had subtracted your y-values.

A coat that normally sells for $800 is on sale for $760. By what percent is the original cost of the coat decreased?
Answer:At least around 30%
Step-by-step explanation:
So when looking at the question there is an 800 and 760.
So the question is basically asking you to subtract your numbers. so do "800-760" And u should get 30 :).
Answer:
95
Step-by-step explanation:
800 (the original price) - 100 perecent
760 (the decreased price) - x perecent
We multiply diganol and divided the only number left, so:
760 times 100 divided by 800.
You get 95!
