25% = 0.25
Therefore, if we want to find 25% <em>of</em> 279.00 , we multiply 0.25 · 279 = 69.75
Answer:
There are
ways for Sally to select her 12 pieces of taffy.
Step-by-step explanation:
The order that the candies are selected is not important. This means that the number of ways is a combination of 12 pieces from 75 varieties.
Combination Formula:
is the number of different combinatios of x objects from a set of n elements, given by the following formula.
![C_{n,x} = \frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=C_%7Bn%2Cx%7D%20%3D%20%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
In this problem, we have that:
![C_{75,12} = \frac{75!}{12!(63)!} = 2.612388941\times10^{13}](https://tex.z-dn.net/?f=C_%7B75%2C12%7D%20%3D%20%5Cfrac%7B75%21%7D%7B12%21%2863%29%21%7D%20%3D%202.612388941%5Ctimes10%5E%7B13%7D)

Answer:
Step-by-step explanation:
Area of Trapezoid= (a+b)*h/2
Here a nd b are the bases.
a = 7 ft; b = 5 ft; h = 4 ft
![Area=\frac{(7+5)*4}{2}\\\\=\frac{12*4}{2}\\\\=12*2](https://tex.z-dn.net/?f=Area%3D%5Cfrac%7B%287%2B5%29%2A4%7D%7B2%7D%5C%5C%5C%5C%3D%5Cfrac%7B12%2A4%7D%7B2%7D%5C%5C%5C%5C%3D12%2A2)
= 24 square feet
Answer:
y = 2x + 2
Step-by-step explanation:
General point-slope form:
point = (x1,y1) = (1,4)
slope = m = 2
y-y1 = m(x-x1)
Substitute values
y - 4 = 2 (x-1)
y = 2x -2 + 4
y = 2x + 2
X Y
(-4,4)
(-3,0)
(-3/2,-9/4)
(-1,-2)
(0,0)
