Here is a formula that you would use to find the total cost of an item that includes tax
(p × 0.07) + p
Answer:
2.30 years
Step-by-step explanation:
The number of fish tripled in the first year, making a total of 240 * 3 = 720 fishes.
(a) The formula for logistic equation is as the following

where P0 = 240 is the number of fishes initially, we can plug in P = 720 and t = 1 to calculate the constant k



b) Using the following formula

with P = 3000, P0 = 240, k = 1.1, we can calculate the number of years it takes to get to 3000 fishes




Answer:
X=5, Y=0
Step-by-step explanation:
-9Y +4X -20=0
-7Y+16X-80=0
1. We can multiply the first equation by 4. This will equal to -36Y +16X-80=0.
-36Y +16X -80 =0
-7Y+16X-80=0
2. We can subtract these two equations.
-36Y +16X -80 =0
-7Y+16X-80=0
We will get -29Y =0. Y=0.
3. Then we can substitute y into the first equation. -9(0) +4x-20 =0. 4x=20. x=5
X=5, Y=0
Answer:
18 signatures
Step-by-step explanation:
Take the total number of signatures and multiply by the fraction that were done in pencil to determine the number done in pencil
30 * 3/5
90/5
18
Okay. So, to find the percent change, we have to do change/original. In this case, it would be 12/15, because 15 and 27 are apart by 12. 12/15 is 0.8. Multiply that by 100 and you get 80. There was an 80% markup of the chair sold to the antique dealer.
