Answer:
the second one is 4
Step-by-step explanation:
3/10 , 30% , 0.3 depends what they want the answer in but they all are the same just different answer forms .
We assume, that the number 48 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 48, so we can write it down as 100%=48.
4. We know, that x% equals 18 of the output value, so we can write it down as x%=18.
5. Now we have two simple equations:
1) 100%=48
2) x%=18
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=48/18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 18 is what percent of 48
100%/x%=48/18
(100/x)*x=(48/18)*x - we multiply both sides of the equation by x
100=2.66666666667*x - we divide both sides of the equation by (2.66666666667) to get x
100/2.66666666667=x
37.5=x
x=37.5
now we have:
<span>18 is 37.5% of 48
</span>minus 100 is 82.5%
Square both sides.
Move all terms to one side.
Simplify using AC method.
<h3>x = 3</h3>
Answer:
parabola
Step-by-step explanation:
That would be a parabola. The "single point" is the "focus" of the parabola, and the "given line" is the "directrix."
