Answer:
5 adults
Step-by-step explanation:
So 4 adults are taken for 32 children. We can use 32 divided by 4 to see how many children it takes to assign an adult. the answer to this would be 8. if 8 more children are added ( which would make 32+8 which is 40) than another adult would be needed.
The function is:
B ( t ) = 4 * e^(0.8 t)
4 * e^(0.8 t) = 400
e^(0.8 t) = 400: 4
e^(0.8 t) = 100 / ln
ln e^(0.8 t) = ln 100 ( and since: ln e = 1 and ln e^x = x * ln e )
0.8 t = 4.6
t = 4.6 : 0.8 = 5.76 ≈ 6
Answer:
D ) 6 hours.
Step-by-step explanation:
45+90+x=180
135+x=180
x=180-135
x=45
I think the answer is -7/4.
You haven't provided any value, but I can tell you the solution set for the inequality.
First of all, expand both sides:

Add 3x to both sides:

Add 6 to both sides:

Which is of course equivalent to

Divide both sides by 9

So, every number smaller than 2 is part of the solution of this inequality.
