saveliy_v [14]
Let k be a constant of proportionality. We can use the given information to write two equations:
24 = k/5 and 12 = k/10.
Solving for k gives k = 120 in both cases.
Let R be the unknown resistance when the current is 15 amperes:
15 = 120/R.
R = 120/15
R = 8 ohms.

You go to Wal-Mart to buy some holiday candy. You decide to buy snickers because they have a special deal on snickers. A bag
Bogdan [553]

Answer:

The piecewise function is given as follows;

\begin{cases}C(n) = \$ 3.45 \times n & \text{ if } x< 4 \\ C(n) = \$ 3.00 \times n & \text{ if } x\geq 4 \end{cases}

Step-by-step explanation:

The given parameters are;

The cost of each bag of snickers = $3.45

The cost of each bag of sneakers when buying 4 or more bags = $3.00

Let "n" be the number of bags of snickers and "C(n)" be the cost of all the snickers purchased

The piecewise function is C(n) = {($3.45 × n) for n < 3

{($3.00 × n) for n ≥ 4

Marge Torelli is a pilot. Her annual group insurance costs $4,400 and her company pays 80% of the cost. How much does Marge pay
kondor19780726 [428]

The insurance company pays 80% of $4,400:
0.8*4400 = $3520

Therefor the amount Marge pays is 4400 - 3520 = $880

Note however that $4400 is the cost of annual group insurance, so to find how much she pays monthly we need to divide the amount she pays in one year by 12:
880/12 = $73.33 (correct to two decimal places)
