You want to purchase a calculator for at most $115. you have saved $30 so far. you earn $7.50 per hour at your job. right and solve an inequality that represents the number of hours h that you need to work.

12

Step-by-step explanation:

you already have $30 so 115-30= 85... then you divide that by the amount you earn to give you the hours 85/7.5=11.3333... but you can not round down because if you only work 11 hours you will not have enough so you must work 12 hours

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
