Sandra saves 8% of her salary for retirement. This year her salary was $2,000 more than in the previous

Tanya [424]

Answer:

$\$40000$

Step-by-step explanation:

Let's start by finding Sandra's salary this year.

We are given that she saved $3,360 or 8% of her total salary this year.

Let's represent her total salary this year as "x" and set up an equation:

$\$3360=8\%x\\$

Note that any percentage is equivalent to that number over 100.

$$3360=\frac{8}{100}x$

Multiply 100 to both sides:

$336000=8x$

Divide both sides by 8

$x=42000$

The question states "this year her salary was $2000 more than in the previous year".

This means that her salary in the previous year is equivalent to:

$42000-2000=40000$

What is the trigonometric ratio for cos N?

bagirrra123 [75]

If we look at our SOHCAHTOA rule:
cos(x) = adj/hyp

The adjacent side of N is 36, and the hypotenuse is 39.

Therefore:
cos(N) = 36 / 39
