Answer:
a < -4
Step-by-step explanation:
Step 1: Write out inequality
-2a - 5 > 3
Step 2: Add 5 to both sides
-2a > 8
Step 3: Divide both sides by -2
a < -4
Here, we can see that any value of <em>a </em>less than -4 works. So <em>a</em> could be -124 or -5, or even -1271293587923857 and it would work.
It says the elevator's can hold minimum 3000 pounds and how many of a 150 pound box can fit without going over the 3000 pound.
So,
Here. I drew a triangle just for this problem. :) You can find it in attachments.
To find the angle, we must use the sine function. To find the angle, we must know the sine of the angle first. The formula for the angle we are trying to find is:
(Forgot to mention,
let the angle = x)

=

Knowing this, we can now derive that:

Using our scientific calculators, we find that:

°
Which is our final answer. You may round accordingly.
Thank you, and I hope that helped. :)
