You want to find the value of __ such that
... __ / 21 > 13
Multiply by 21.
... __ > 21·13
... __ > 273
The smallest whole number greater than 273 is 274.
_____
That is, 274/21 > 13
Answer:
26-33-40-47-54-61-68-75-82-89-96
In 13, x=27.496
In 14, x=16.824
In 15, x=51.34°
<em />I did this in my head; it would take longer to write it out. I'll show you the trig if need be.
Answer:
3/4
Step-by-step explanation:
First of all, we need to calculate the slope of the line shown. This can be computed as:
where
is the increment along the y-direction
is the increment along the x-direction
We can choose the following two points to calculate the slope of the line shown:
(-3,2) and (0,-2)
And so, the slope of the line shown is
Two lines are said to be perpendicular if the slope of the first line is the negative reciprocal of the slope of the second line:
Using 
, we find that a line perpendicular to the line shown should have a slope of
14.5% = 0.145
Step-by-step explanation:
The term 'percent' (%) actually means per 100. So when you say 14.5% it means 14.5 per 100. So when you put that into an equation it actually means:
So when you solve it, 14.5% is actually 0.145 and not 14.5.
Your friend is then incorrect because:
14.5% ≠ 14.5
