Which is greater? The square root of 121 or the cube root of 125. Explain your answer.
nikdorinn [45]

Answer:

The square root of 121.

Step-by-step explanation:

The square root of 121 is 11. 11x11=121 which makes the square root of 121, 11. The cube root of 125 is 5. Cube roots are numbers that are multiplied by each other to make a number, 125 is 5x5x5 so the cube root is 5. 11 is a greater number than 5 which makes the square root of 121 greater.

Outline the steps for taking cross sections of a rectangular prism.
fgiga [73]

Answer:

  • find a suitable cutting tool
  • cut the prism on the plane of interest

Step-by-step explanation:

A cross section is the intersection of a cut plane with the object of interest. In a classroom setting, we often try to do the cross sectioning mentally or with diagrams, rather than physically cutting anything. Sometimes, there is no substitute for actually performing the cut to see what the cross section looks like.

For certain samples that don't take kindly to cutting, we sometimes encase them in a block of material that helps them hold their shape during the process. Sometimes the "cutting" is performed by grinding away the portion of the material on one side of the cut plane.

428 students were surveyed about their preferences of sports. 146 students like football, 144 students like baseball, and 45 stu
ella [17]

This is what we already know:


\left[\begin{array}{cccc} &YB&NB&total\\YF&45&[unknown]&146\\NF&[unknown]&[unknown]&[unknown]\\total&144&[unknown]&428\end{array}\right]


And using this information, we can fill the table out. Remember that everything must add up to the total in the column and row. The complete table looks like this:


\left[\begin{array}{cccc} &YB&NB&total\\YF&45&101&146\\NF&99&183&282\\total&144&284&428\end{array}\right]


Using the complete table, we see the fraction for students that only like baseball is \frac{99}{428} and students who only like football is \frac{101}{428} . All you need to do is add these fractions together to get your answer.


\frac{99}{428} +\frac{101}{428} =\frac{200}{428}


In short, 200 students only like one of the two sports.
