Latrell bought 4 bags of powdered sugar. He got a total of 5 1/2 cups of sugar. How many cups of sugar were in each bag?
Stels [109]
So all 4 bags of sugar yielded 5 and 1/2 cups..... well.. how many in each one?  well, let's split the 5 and 1/2 evenly in 4 pieces.

\bf \stackrel{mixed}{5}\frac{1}{2}\implies \cfrac{5\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{11}{2}}\\\\
-------------------------------\\\\
\cfrac{\quad\frac{11}{2} \quad }{4}\implies \cfrac{\quad\frac{11}{2} \quad }{\frac{4}{1}}\implies \cfrac{11}{2}\cdot \cfrac{1}{4}\implies \cfrac{11}{8}\implies \stackrel{cups}{1\frac{3}{8}

Find the slope that is perpendicular to the graph of the equation y-2x=-5
Sloan [31]
We can rearrange the initial equation to y=mx+b

y=2x-5

Since perpendicular slopes must equal -1,
x=the perpendicular slope
2x=-1
x=-1/2

(Or you can just take the negative reciprocal above is just the "formula form" for it)

Therefore, the perpendicular slope is -1/2

A prism has a square base with a side length of 4 1 2 4 1 2 feet. The height of the prism is 6 feet. What is the volume of the p
dusya [7]

We have been given that a prism has a square base with a side length of 4 1/2 feet. The height of the prism is 6 feet. We are asked to find the volume of the prism.

We know that volume of prism is base area times height.

\text{Area of base}=\text{Area of square}=\text{Side length}^2

\text{Area of base}=(4\frac{1}{2})^2

\text{Area of base}=(\frac{9}{2})^2

\text{Area of base}=\frac{9^2}{2^2}

\text{Area of base}=\frac{81}{4}

\text{Volume of prism}=\frac{81}{4}\times 6

\text{Volume of prism}=\frac{81}{2}\times 3

\text{Volume of prism}=\frac{243}{2}

\text{Volume of prism}=121\frac{1}{2}

Therefore, the volume of prism is 121\frac{1}{2}\text{ ft}^3 and option D is the correct choice.
