Answer:
x = 3.5
Step-by-step explanation:
15(1/2) = 7.5
7.5+6 =13.5
subtract 17 and divide by -1 to isolate x 13.5-17/-1
x = 3.5
We know that the mixture has 14 mm of ink. Of these, 35% are blue pigment, hence the mixture contains 4.9 mm of blue ink. Ink A contains 10%*4mm=0.4mm of blue ink. The difference, 4.5 mm of blue ink must have come from ink B. Thus ink B contains 4.5 mm of blue ink and is in total 10mm. After that, we can calculate the percentage; we divide 4.5/10=0.45 and this is the ratio of blue ink to total ink (in Ink B). If we transform it to percentages it is 45%
Answer:
After 9 years, the population reach 4000.
Step-by-step explanation:
The given function P(t) represents the size of a small herbivore population at time t (in years).
We need to find the number of years after which population reach 4000.
Substitute P(t)=4000 in the above function.
Divide both sides by 1000.
Taking ln on both sides.
![[\because \ln e^x=x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20e%5Ex%3Dx%5D)
Divide both sides by 0.16.
We need to find the number of years. So, round the answer to the next whole number.
Therefore, after 9 years, the population reach 4000.
