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:

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

I am joyous to assist you anytime.

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) $4k - 18 = 18 + k$

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 $j = 4k$

$j = 4 * 12$

$j = 48$

$\huge\text{Hey there!}$

$\mathsf{x-\dfrac{3}{2}=3}$

$\large\textsf{You have to SIMPLIFY the SIDES of The given EQUATION}$

$\mathsf{x + (-\dfrac{3}{2}) = 3}$

Solve for T: T/4+8>-10 A. T>72 B> T>-72 C. T T<-72

Alinara [238K]

Answer:

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

Step-by-step explanation:

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