Find last year’s salary if, after a 3% pay raise, this year’s salary is $30,900

Liono4ka [1.6K]

Your answer is $30,000.
The way I have answered this is quite strange, but I'll do my best to explain it. So because we know that $30,900 is 3% than last year, we can call it 103%. This allows us to form a ratio and therefore find 100%.
30,900 : 103
÷ 103
300 : 1
× 100
30,000 : 100
Which means $30,000 is 100%, or 3% less than $30,900. I hope this helps! Let me know if it was confusing or anything :)

amid [387]

A point that is half way of line segment is the midpoint

Let (6, 7) be (x₁, y₁) and (-7, -6) be (x₂, y₂)

Mid point of HI = ( $\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}$ )
Mid point of HI = ( $\frac{6+-7}{2}, \frac{7+-6}{0})$
Mid point of HI = ( $- \frac{1}{2} , \frac{1}{2}$ )

Santiago's statement is not correct

Answer:

r = 8 ft

Step-by-step explanation:

The formula for circumference of a circle is

C = 2 * pi *r

We know the circumference is 16 pi

16 pi = 2 pi r

Divide each side by 2pi

16 pi /2 pi = 2 pi r / (2pi)

8 = r
