kompoz [17]

The required number of red cards is 9 in the pile.

Given that,
The number of black cards in a pile is 4 times the number of red cards. There are 36 black cards in the pile.
To determine how many red cards are there.

<h3>What is arithmetic?</h3>

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Let the number of the red cards be r, and the number of the black cards be b
Black cards in a pile are 4 times the number of red cards.
b = 4r
Now,
There are 36 black cards in the pile.
b = 36
4r = 36
r = 36 / 4
r = 9

Thus, the required number of red cards is 9 in the pile.

ngozi earns \$24{,}000$24,000dollar sign, 24, comma, 000 in salary in the first year she works as an interpreter. each year, she
goblinko [34]

The function that Ngozi's salary s(t) in dollars, t years after she starts to work as an interpreter is given by S = 24000 *  (1.035)^t.

What is a function?

  • A function in mathematics from a set X(ax) to a set Y allocates exactly one element of Y to each element of X(ax).
  • A relation between a collection of inputs and labor is known as a function.

You can use the fact that the raise is done on the previous year's salary.

Let the initial salary be P = $24000

After 1 year, her salary increased by R = 3.5% which, thus,

Total salary = P + increment

Similarly going on, we get

P_t = P(1+ \frac{R}{100})^t = S (we can say)

Putting values of P(value of P) and R(value of R), we get

S = 24000(1 + 0.035)^t = 24000 *(1.035)^t

Thus,

The function that Ngozi's salary s(t) in dollars, t years after she starts to work as an interpreter is given by

S = 24000 *  (1.035)^t
