Answer:
$13
Step-by-step explanation:
Given that :
Increase in salary factor = 11/10
New salary = $14.30
Initial salary = x
To obtain the value of the initial salary,
The product of the scale factor by the initial salary sgiuf give the amoi tof the new salary
11 / 10 * x = 14.30
1.1x = 14.30
x = 14.30 / 1.1
x = $13
Hence.initial salary per hour = $13
Check the picture below.
using a second for it, since it's a horizontal line, then say hmmm we'll use the y-intercept, or (0, 1), so the equation of a line that passes through (2,1) and (0,1)
Answer: 
==========================================================
Work Shown:
Focus entirely on triangle ABD (or on triangle BCD; both are identical)
The two legs of this triangle are AB = 8 and AD = 8. The hypotenuse is unknown, so we'll say BD = x.
Apply the pythagorean theorem.

So that's why the diagonal BD is exactly
units long

Answer:
500 de no ficcion y 1500 de ficcion
Step-by-step explanation:
si tomamos que hay 2000 libros hay que buscar un numero que multiplicado 3 veces por si mismo nos de 2000, como ya tenemos el 500 que seria los libros de no ficcion, ahora tenemos que e si al multiplicarlo por 3 veces nos da los 1500 que nos falta para completar 2000
500 + 1500 = 2000
