Answer:
The waste Suzanne is going to have is around 7.726.
8 if looking for nearest square foot.
Step-by-step explanation:
Area for a square - x*x (length times length)
Area for a circle - r^2*pi
Find the area of the circle first, which plug in r as 3.
3^2*pi
9pi
≈28.27433
Notice for a circle inside a square, the length of the square is the diameter of the circle.
By knowing 2r=diameter, we know the length of the square is 6
substitute x as 6.
6*6=36
Find the waste= Area of square - Area of circle
36-28.27433
≈7.726
The image I attached should give you a clue on how the problem is being done and help you to understand what the 3 feet means.
The temperature in London at 2pm is 14°C
I can only use math to explain it. What is 100%?
100% =
percent means per 100.
so 120% = 120/100 = 1.2
120% of a whole number. For example 120% * 10 =
![\frac{120}{100} * 10](https://tex.z-dn.net/?f=%20%5Cfrac%7B120%7D%7B100%7D%20%2A%2010%20)
= 12
is it greater than 10.
The line is called the directrix. Here we have a vertical directrix, so a parabola sideways from usual.
Geometry is best done with squared distances. The squared distance from an arbitrary point (x,y) to the vertical line x=2 is
![(x-2)^2.](https://tex.z-dn.net/?f=%28x-2%29%5E2.)
We equate that to the squared distance of (x,y) to the focus (-2,0):
![(x-2)^2 = (x - -2)^2 + (y - 0)^2](https://tex.z-dn.net/?f=%28x-2%29%5E2%20%3D%20%28x%20-%20-2%29%5E2%20%2B%20%28y%20-%200%29%5E2)
![x^2 -4x + 4=x^2 +4x +4 + y^2](https://tex.z-dn.net/?f=x%5E2%20-4x%20%2B%204%3Dx%5E2%20%2B4x%20%2B4%20%2B%20y%5E2)
![-8x = y^2](https://tex.z-dn.net/?f=-8x%20%3D%20y%5E2)
We could call that done. A more standard form might be
The answer is 5.75+4.5/.06. The shop uses .06 pound of the mixture of the two for each sundae so it will be divided by .06 therefore the complete expression for this problem is 5.75+4.5/.06
