Answer:
12 Tables.
Step-by-step explanation:
There are many ways you can solve this with, here is the simplest.
Lets make it as a statement, IF 1 table has 5 chairs THEN how many X tables have 60 chairs.
Make it simplier:
1 Table = 5 Chairs
X Tables = 60 Chairs
using the cross multiplication method you will get
5X = 60
Divide by 5
X = 12
Which means that the room has 12 tables.
I believe the answer for the second one is B ( I took this last year but I think it’s that one)
Part A: Let the September price be x, then
1.2x = 1.5
x = 1.5/1.2 = 1.25
Therefore, September price is $1.25
Part B: In September, they earned 0.4 * 1.25 * 900 = $450
In October, they earned 0.4 * 1.5 * 700 = $420
Therefore, they earned more money in September.
Answer:
T = 200 months
Step-by-step explanation:
Given the model to be
dp/dt = p(10-1-10-7p) where p(0) = 6000
dp/dt = p(-1-7p)
dp/dt = -p+7p²
But since P(0) = 6000
We plug this value into the equation
P = -6000+7(6000)²
P = -6000+252000000
P = 251994000. .limiting value
Differentiating dp/dt w.r.t p
dp/dt = -1+14p
dp'/dt = 14p-1
Plugging p(0) = 6000 into the above we have that
dp'/dt = 14(6000)-1
P' = 84000
Time population would be equal to 3/2 the limiting value
T = 3/2× 84000 = 126000
T = 25199400/126000
T = 199.99months
T = 200 months.
