Answer:
110 is not a perfect square.
Step-by-step explanation:
A perfect square is a number that can be expressed as the product of two equal integers.
Here in this case the answer is "a". The way to find the percentage is to add all the numbers you have which is $49. And then you need to use it to divide it with the percentage you need for the number. Which in this case you are searching for shoelaces and it $4. So you divide the cose of the shoelaces $4 to the total amount $49. And then you multiply by 100 to get the percentage. If you round it off the the tenth place you should get 8.2%
<span>supplement angles, sum = 180
lets x = angle
</span><span>its supplement = 180 - x
x + 17x = 180
18x = 180
x = 10
180 -10 = 170
answer
angle = 10
its </span><span>supplement = 170</span>
This is like the equation of a line where y is the area, x is the time, and 8.5% is your slope. So you have y=0.085x+b (reason why I switched 8.5% into 0.085 is because that is how you write a percent as a decimal).So now you need to find what b is. So you know orignally the area is 2400km^2 at x=0 years (this is what it is initially).If you plug those numbers in you have:2400=0.085(0)+bThen after solving for b, you can write your equation as:y=0.085x+(whatever you found b to be)Then plug 13 in for x and you have your answer. y=-.085(13)+2400
