AveGali [126]

Answer: There are 2635 acres covered 24 hours later.

Step-by-step explanation:

Since we have given that

At time t = 0, number of acres forest fire covers = 2008 acres

We first consider the equation:

$A=\int\limits^t_0 {8\sqrt{t}} \, dt\\\\A=8\dfrac{t^{\frac{3}{2}}}{\frac{3}{2}}+C\\\\A=\dfrac{16}{3}t^{\frac{3}{2}}+C$

At t=0, A= 2008

So, it becomes,

$2008=C$

So, now it becomes,

$A=\dfrac{16}{3}t^{\frac{3}{2}}+2008\\\\At\ t=24,\\\\A=\dfrac{16}{3}(24)^{\frac{3}{2}}+2008\\\\A=2635.06$

Hence, there are 2635 acres covered 24 hours later.

Mrs Allen gave some peanuts to her children to take to the zoo. Zach got half the peanuts, Wendy got one-fourth of what was left

Effectus [21]

Answer:

240 peanuts

Step-by-step explanation:

Let x be the number of peanuts Mr. Allen had.

Zach got half the peanuts, then Zach got $\dfrac{x}{2}$ peanuts and

$x-\dfrac{x}{2}=\dfrac{x}{2}$ peanuts left.

Wendy got one-fourth of what was left, then Wendy got

$\dfrac{1}{4}\cdot \dfrac{x}{2}=\dfrac{x}{8}$ peanuts and

$\dfrac{x}{2}-\dfrac{x}{8}=\dfrac{3x}{8}$ peanuts left.

The twins, Ron and Don shared the remaining peanuts, then each of them got

$\dfrac{1}{2}\cdot \dfrac{3x}{8}=\dfrac{3x}{16}$ peanuts.

If Ron got 45 peanuts, then

$\dfrac{3x}{16}=45,\\ \\3x=45\cdot 16,\\ \\x=15\cdot 16,\\ \\x=240\ \text{peanuts.}$

Can someone help me? <br> What is 8=6+x/2?

NeTakaya

8 = 6+x/2

Get rid of the denominator: LCM of all denominators( in this case we only have 1 denominator ) , then multiply to all expressions

8x2 = 6+x/2x2

The denominator 2 gets crossed out as well as the other 2

16 = 6+x

Now constants on one side and variables on the other

16-6 = 6-6+ x

Now your answer

10= x

Or

x = 10
