Answer:The equation when solved for g is ---->g=P/dt - 4/t
Step-by-step explanation:
What this question is asking us is
A) From -40C to 5 0c How much did it rise
The formula for this would be
Risen Temperature - Initial Temperature
The risen temparauture is 5 so we plug the 5 in first then the 4 so it would look like
5-(-4)=9
And remeber when you have 2 negatives it becomes a positie, 5+4=9
The asnwer for A is 9 degress
B) The tempurater then fell by 7 degress from 5 so we just have to do
5 - 7
which is -2 Celcius
Answer:
A
Step-by-step explanation:
The per capita income is the income of a person in a nation. The per capita is calculated by dividing the gross income of the nation by total population.
Let
Pci = Per Capita Income
I = Total income
and
P = Total population
Then,
Pci = I/P
The answers are A, C, A in the order they are listed
Answer:
2/5
Step-by-step explanation:
25% is equal to 1/4
Lets think of this as money
If we take .25 and multiply it by 4 we get 100 or 1.00
Lets take 5/20
5/20 is also equal to 25%
For this one, let's change the fraction to an equivalent fraction. To do this I'm going to multiply both the top and bottom by 5.
5*5/20*5
That gets us 25/100
Back to thinking money-- we know that 25/100 is equal to 25%
25/100
We just determined that 25/100 is 25% using the problem above.
-----------------------------------------------------------------------------------------------------------------
The odd one out-- 2/5
2/5 is equal to 40%
If we think of this fraction as money and we get an equivalent fraction-- 40/100
We can clearly see that that is not 25/100, 1/4, 5/20, or even 25%
Hence making it not equivalent to 25%
