Answer:

Step-by-step explanation:

Just plug in 20 for t:

f(20)=\frac{60*20}{20^2+46}=\frac{1200}{400+46}=\frac{1200}{446}=2.69058

Answer:

\displaystyle 2\frac{154}{223}\:mg. = f(20)

Step-by-step explanation:

\displaystyle \frac{60[20]}{20^2 + 46} = \frac{1200}{400 + 46} = \frac{1200}{446} = 2\frac{154}{223}

4. Jim and Kirk are playing a card game where they trade chips. At the beginning of the game, Jim has four times as many chips a
s2008m [1.1K]

Answer:

(a) j = 4k

(b) 4k - 18 = 18 + k

(c) Jim initially had 48; Kirk initially had 12

Step-by-step explanation:

Given

j = Jim

k=Krik

Solving (a): An equation for the amount they originally had.

From the question, we understand that j is 4 times as many as k.

Mathematically, this is:

j = 4 * k

j = 4k

Solving (b): Equation after Kirk wins

Initially Kirk had k.

To get the new expression, we add 18 to k.

This gives: 18 + k

In the same vein, Jim's number of chirps will reduce by 18.

Initially, Jim had j chirps (or 4k chirps)

To get the new expression, we subtract 18 from j.

This gives: j - 18

So, the equation is:

j - 18 = 18 +k

Solving (c): Number of chirps they started with.

In (b), we have:

j - 18 = 18 +k

Substitute 4k for j

4k - 18 = 18 + k

Collect Like Terms

4k - k = 18 + 18

3k = 36

Divide both sides by 3

k =12

Substitute 12 for k in j = 4k

j = 4 * 12

j = 48

Answer:

\huge\boxed{B.\ T>-72}

Step-by-step explanation:

\dfrac{T}{4}+8>-10\qquad|\text{subtract 8 from both sides}\\\\\dfrac{T}{4}+8-8>-10-8\\\\\dfrac{T}{4}>-18\qquad|\text{multiply both sides by 4}\\\\4\!\!\!\!\diagup\cdot\dfrac{T}{4\!\!\!\!\diagup}>(4)(-18)\\\\T>-72
