Between the ages 2 and 20, the weight W of an American boy is logistic function of his age. For boys at the 50 percentile, the differential equation for W can be approximated by 4W = 0.0008W (216 - W), where W is measured in pounds and t is measured in years beyond the age of 2. Express W as a function of t subject to the initial condition W(0) = 24

Answer:

Step-by-step explanation:

2 times the first and –1 time the second will eliminate the x variables in the equations.

Option E is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an equation.

We have,

(1/3)x - (2/3)y = 7 ____(1)

(2/3)x + 3y = 11 _____(2)

Now,

Multiply 2 on equation (1).

Multiply - 1 on equation (2).

We get,

(2/3)x - (4/3)y = 14

-(2/3)x  - 3y = -11    

           -(4/3)y - 3y = 14 - 11

Now x variable gets eliminated.

Thus,

2 times the first and –1 time the second will eliminate the x variables in the equations.

Both of them are right

The amount of carpet needed is 189 7/8 feet

Step-by-step explanation:

Here, we want to get the person with the right calculations step between Michael and Tracy

From what we can see in the question, both exactly have the same calculations

They only differ in the number to put first

So we can say both are right

The amount of carpet needed will be;

12 1/4 * 15 1/2

= 49/4 * 31/2 = 1519/8

= 189 7/8 square feet

Answer:

24% yes yes yes

Answer:

24% or [tex]\frac{6}{25}[/tex]=24%

Step-by-step explanation:

We know that

[tex]\frac{6}{25}[/tex]

Is the same as

6÷25

Then, using long division gives us

0.24

Lastly, multiplying 0.24 by 100 gives us

24

Now add the percent sign

24%

Answer:

6:24 or 1:3 (this is reduced)

Step-by-step explanation:

I added 18 plus 6 together getting 24, which tells me that there are 24 flowers in Mr. Lopez's garden. I then set up the ratio as 6:24, but i knew that i could reduce it. (I'm noy sure if you want it reduced or not) So I divided both sides by 6 getting the ratio 1:3.

Answer:

   [tex](\frac{8^4}{10^4} )^{-\frac{1}{4} }[/tex]  = [tex]\frac{5}{4}[/tex]

Step-by-step explanation:

Explanation

Given  

       [tex](\frac{8^4}{10^4} )^{-\frac{1}{4} }[/tex]

By using algebra formulas

  [tex](\frac{a}{b} )^{m} = \frac{a^m}{b^n}[/tex]

[tex](\frac{8^4}{10^4} )^{-\frac{1}{4} } = \frac{(8^{4})^{\frac{-1}{4} } }{(10^{4} )^{\frac{-1}{4} } }[/tex]

[tex](a^{m} )^{n} = a^{mn}[/tex]

[tex]\frac{(8^{4})^{\frac{-1}{4} } }{(10^{4} )^{\frac{-1}{4} } } = \frac{8^{4X\frac{-1}{4} } }{10^{4 X\frac{-1}{4} } }[/tex]

          = [tex]\frac{8^{-1} }{10^{-1} }[/tex]

           [tex]= \frac{10}{8} \\= \frac{5}{4}[/tex]

Final answer:-

 [tex](\frac{8^4}{10^4} )^{-\frac{1}{4} }[/tex]  = [tex]\frac{5}{4}[/tex]

100/3 yards

Step-by-step explanation:

36 inches=1 yard, so 1200/36 will equal how many yards 1200 inches is.

Simplify:

1200/36

divide numerator and denominator by 12 and you get 100/3

100/3 yards

Tracey kicks the ball for 100/3 yards.

Given that, at soccer practice, Tracey's best kick travelled a distance of 1,200 inches.

We need to find out for how many yards did she kick the ball.

Inch-to-yard conversion explanation

So to convert from a value in inches to one in yards, we need to divide by 36. To convert a value in yards to inches, we need to multiply by 36.

Now, the number of yards =1200/36=100/3

Hence, Tracey kicks the ball for 100/3 yards.

48/8=8  this means Elsa can create a minimum of 8 small snowmen to cover the display area. 8x2=16 which means Elsa would have 4 spare frozen energies. OR 10 can go into 48 a maximum of 3 times to make LARGE snowmen without using all her energy but not enough to cover the display area. 48-30=18 Elsa still has five energies left so she can build two SMALL snowmen giving her a total of 16 with a remainder of two square feet uncovered. OR Elsa can make two large snowmen (covering 20 square feet and leaving her 10 energies left) and make five small snowmen which would cover a total of 40 square feet. 40+20=60 which is too much. 60-48=12. If Elsa made four small snowmen instead of five it would equal 32. 32+20=52 which is still too much. If Elsa made three small snowmen instead of four it would equal 24. 24+20= 44 which isn't enough to fill the display.
