40:10 is equivalent to 2:0.5
Think of it as a fraction. (40/10) We can then reduce that. So we divide 10 by 10 and what we do to one side we have to do to the other so we divide 40 by 10 and we get 4/1 we can then divide both sides by 2 and get 2/0.5 or 2:0.5 :D

HELP 100 POINTS The population of a city is modeled with the function P=250,000e^0.013t​, where t is the number of years since 2
erma4kov [3.2K]
Pretty difficult problem, but that’s why I’m here.
First we need to identify what we’re looking for, which is t. So now plug 450k into equation and solve for t.
450000 = 250000e^0.013t
Now to solve this, we need to remember this rule: if you take natural log of e you can remove x from exponent. And natural log of e is 1.
Basically ln(e^x) = xln(e) = 1*x
So knowing this first we need to isolate e
450000/250000 = e^0.013t
1.8 = e^0.013t
Now take natural log of both
Ln(1.8) = ln(e^0.013t)
Ln(1.8) = 0.013t*ln(e)
Ln(1.8) = 0.013t * 1
Now solve for t
Ln(1.8)/0.013 = t
T= 45.21435 years
Now just to check our work plug that into original equation which we get:
449999.94 which is basically 500k (just with an error caused by lack of decimals)
So our final solution will be in the 45th year after about 2 and a half months it will reach 450k people.

Find x - y subtracted from 0
alexandr1967 [171]
The expression you want to simplify is 0-(x-y).
0-(x-y)
=-(x-y)
=-x+y

You just have to treat the negative sign in front of (x-y) as a -1 and distribute it to both x and -y.

Describe the relationship between n and 4 that will make the value of the expression 7xn4greater than7
valina [46]

Answer:

As per the statement: the value of the expression 7 x n/4 greater than 7.

To describe the relationship between n and 4.

"greater than" symbol is represented by '>'

The value of expression 7 \times \frac{n}{4} grater than 7 is;

7(\frac{n}{4}) > 7

Divide by 7 both sides we get;

\frac{n}{4} > 1

Multiply both sides of an equation by 4 we get;

n > 4

Therefore, the relationship between n and 4 is, n > 4
