Solve for h.
P=mgh
Answer choices:
H=P-mg
H=pg/m
H=p/mg
H=P+mg
Answers
p/mg=h
the answer is:
H=p/mg
Answer:
The answer is H = p/mg.
Step-by-step explanation:
Give the variables actual values, and then solve. Let's say:
H = 4
G = 3
M = 2
The equation P = mgh tells us to multiply m x g x h. 3 x 2 x 4 = 24, so P = 24.
Now our values are:
P = 24
H = 4
G = 3
M = 2
So now we have to find which equation is equal to 4, or the value we have substituted for H.
So let's test the answer choices out.
H = P - mg. This would say that 4 = 24 - 2 x 3. 2 x 3 = 6, and 24 - 6 is 18. 18 is not equal to 4, so H = P - mg is not the correct answer.
H = pg/m. This would say that 4 = 24 x 3 divided by 2. 24 x 3 is 72, and 72 divided by 2 is 36. 36 is not equal to 4, so H = pg/m is not the correct answer.
H = P + mg. This would say that 4 = 24 + 2 x 3. 2 x 3 is 6, and 24 + 6 is 30. 30 is not equal to 4, so H = P + mg is not the correct answer.
H = p/mg. This would say that 4 = 24 divided by 2 x 3. 2 x 3 is 6, and 24 divided by 6 is 4. 4 is equal to 4, so H = p/mg is the correct answer.
This formula of substituting the variables for values can work for any value. Just do yourself a favor and make it easy for yourself, by not choosing values like 13045. That's just a waste of time.

An increase by 15% means 15 added to per cent (per = each; cent=100).
If the population was 100 in the year 2000 then it would be 115 in the year 2014. (adding 15 to 100)
The population was 116500 in the year 2000 and it increased to 133975 in the year 2014.
Let the population be x in the year 2000.
Using ratio and proportion
Year 2000 : Year 2014
100 : 115
x : 133975
Applying cross product rule
x × 115= 100× 133975
x= 100× 133975/115
x= 116500
The population was 116500 in the year 2000 and it increased to 133975 in the year 2014.
Answer:
116500
Step-by-step explanation:
We are looking for the number of twin births in 2000.
Let the number of twin births in 2000 be x.
The number of twin births in 2000 is 100% of the number of births in 2000 since 100% of something is the entire thing.
The number of twin births went up 15% from 2000 to 2014, so in 2014, the number of twin births was 100% of the number of twin births plus another 15% of the number of twin births.
100% + 15% = 115%
The number of twin births in 2014 was 115% of x.
The number of twin births in 2014 was 133975.
115% of x = 133975
115% * x = 133975
1.15x = 133975
x = 133975/1.15
x = 116500
The number of twin births in 2000 was 116500.
(y-3)^2=4y-12
Answers
(y-3)²=4y-12
First we need to start by subtract 4y-12 from both sides
y²-6y+9-(4y-12)= 4y-12-(4y-12)
y²-10y+21=0
Now we need to do the factorization of the equation
we gonna factor the left side of it
(y-3)(y-7)=0
Set factors equal to 0
y-3=0 or y-7=0
y=3 or y=7
