The length (in centimeters) of a typical Pacific halibut t years old is approximately f(t) = 200(1 − 0.956e−0.18t). Suppose a Pa

horsena [70]

Answer:

7.2 years

Step-by-step explanation:

$f(t) =200(1 - 0.956e^{-0.18t})$

where f(t) is the length and t is the number of years old

given the Mike measures 148 cm, we need to find out the age

So we plug in 148 for f(t) and solve for t

$148 =200(1 - 0.956e^{-0.18t})$

divide both sides by 200

$\frac{148}{200} = 1 - 0.956e^{-0.18t}$

Now subtract 1 from both sides

$-0.26= - 0.956e^{-0.18t}$

Divide both sides by -0.956

$\frac{0.26}{0.956} =e^{-0.18t}$

Now take ln on both sides

$\frac{0.26}{0.956} =e^{-0.18t}$

$ln(\frac{0.26}{0.956} )=-0.18tln(e)$

$ln(\frac{0.26}{0.956} )=-0.18t$

divide both sides by -0.18

t=7.2

So 7.2 years

Rosy has 16 pencils and 24 erasers. She is putting together packets that will havean equal number of pencils and erasers in each

N76 [4]

$16 = 2^4$

$24 = 2^3 \times 3$

$\text{HCF =}2^3 = 8$

Maximum number of packets = 8

16 ÷ 8 = 2
There are 2 pencils in each packet.

24÷8 = 3
There are 3 erasers in each bag.

Rosy can have a maximum of 8 packets. Each packet has 2 pencils and 3 erasers.

1) You are eating 3/4 cup of ice cream, 1/8 cup of chocolate syrup, and one sixteenths cup of cherries. How many (total) cups is

lara [203]

Answer:

3/4=ice cream

1/8=chocolate syrup

1/16=cherries

Total=3/4+1/8+1/16

$\frac{3X4}{4X4} +\frac{1X2}{8X2} + \frac{1X1}{16X1} \\\frac{12+2+1}{16} = \frac{15}{6}$

Total cups =15/6=2.5 cups.

Hoped this helped!

30% of all the students in a school are in a play all students except for 140 are in the play how many students are in the schoo

Bezzdna [24]

To figure out how many kids are in the school, you must set up an equation with x representing the number of students. 30% of the students are in the play, so that would be represented by 0.3x. We also know that 140 students are not in the play, that could be represented by x-140. These two equations will equal each other since they both represent the same information, which is the number of children in the play. You set those two equations equal to one another (0.3x = x-140). You then can add 140 to the left side of the equation and subtract 0.3x from the right side. We do this in order to get both values of x on the same side of the equation. We then can simplify the right side of the equation by subtracting 0.3x from 1x. We get 0.7x. Our equation now looks like 140 = 0.7x. We must now divide each side of the equation by 0.7 in order to get the x all by itself and find its value. 140 divided by 0.7 is 200. The number of students in the school is 200.
