Answer:
B.
Step-by-step explanation:
Total surface area of the square pyramid
= 4 times the area of one triangle + Area of square
![= 4 \times \frac{1}{2} \times 6 \times 6 + {6}^{2} \\ \\ = 72 + 36 \\ \\ = 108 \: {in}^{2}](https://tex.z-dn.net/?f=%20%3D%204%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%206%20%5Ctimes%206%20%2B%20%20%7B6%7D%5E%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%2072%20%2B%2036%20%5C%5C%20%20%5C%5C%20%20%3D%20108%20%5C%3A%20%20%7Bin%7D%5E%7B2%7D%20)
Step-by-step explanation:
y=kx
say that y is the original prince and x is the sale price
15=k(10)
15/10=k
3/2=k
you can check with the next problem to check if it is the same
25=k(20)
25/20=k
5/4=k
so you take 5/4-3/2=-1/4 so the constant is -1/4
Hope that helps :)
Answer: ![21.75\ milliliters](https://tex.z-dn.net/?f=21.75%5C%20milliliters)
Step-by-step explanation:
Let be "x" the original volume of the solution (in milliliters) before the acid was added and "y" the volume of the solution (in milliliters) after the addition of the acid.
Set up a system of equations:
![\left \{ {{x+y=90} \atop {y=3x+3}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bx%2By%3D90%7D%20%5Catop%20%7By%3D3x%2B3%7D%7D%20%5Cright.)
Applying the Substitution Method, you can substitute the second equation into the first equation and then solve for "x":
According to the normal distribution curve:
<span>"the percent of women whose heights are between 64 and 69.5 inches"</span> represents the values within 2 standard deviation ,,,
And that value is 95% of the whole data
