Find cost of pens and mechanical pencils
pen cost=number of pens times cost pe pen
pencost=10 times 0.35=3.50
mech cost=number of mechs times cost pe mech
mechcost=5 times 0.89=4.45
4.45 is more than 3.50
yes, mech cost mre than pens
Assuming the fish pond is round, what you're given is the circumference.
So you know that 2<span>πr = 27.
We want to solve for the diameter, or d = 2r. We should isolate that.
2r = 27/</span><span>π
2r = 8.59 yards, or ~9 yards.</span>
Much as you would like it to be D, it isn't. D has its center at (3,4). You must change the sign on both numbers inside the brackets.
You need something that looks like (x + 3)^2 + (y + 4)^2. So it could be A or B. How do you know which? The graph should give you an answer, then we'll talk about it. The red circle is A the blue circle is B. Which one is correct?
The answer to that is that the center is 5 units away from the origin. The radius of this circle is the sqrt(25) = 5 units away from the center. The blue one has a radius of sqrt(5) which is something over 2. It is not enough. So what's the answer?
Answer:
1.5 cups of flour
Step-by-step explanation:
this is because if the recipe is ut in half, the ingredients must be as well. 3/2=1.5 simple.
Answer: - 8.89%
I am going to explain you in detail ir order to help you to be able to do this kind of problems by yourself.
The definition of percent change, %, is:
change
% = ---------------- * 100
base value
The base value is from where you start or the value for which you want to asses the variation.
So, in this case the base value is 90 (starting value).
The change is final value - initial value = 82 - 90 = - 8. The negative sign means that the value decreased.
So, following the formula you get:
82 - 90 - 8
% = ----------- * 100 = -------- * 100 = - 8.89
90 90
Answer: the percent of change is - 8.89 %, meaning that the value decreased 8.89%.
