37 1/2% of _________ is 36, Please help show work I am really confused.

Before you start working on this problem, make sure you know
how to use a couple of the tools in your toolbox:

Tool #1: 37-1/2 percent means 0.375

Tool #2: In math problems, "of" almost always means "times".

====================================

Your question says

   "37-1/2 percent of blank is 36".

Translate it with your tools:

      0.375 times blank = 36 .

Divide each side by 0.375:     Blank = 36 / 0.375 .

Now grab your pencil or your calculator, and find the value of that
fraction (do the division). Blank is equal to the value of the fraction.

To check your answer (find out whether it's correct):

Do exactly what the question says.

Multiply (0.375) times (your answer). If you get 36,
then your answer is correct. If not, it's not.

Answer:

72.5

Step-by-step explanation:

5, 12, 15, 23, 42, 51, 55, 66, 68

42 = median

Q1 median = 21

Q2 median = 93.5

93.5 - 21 = 72.5

A lamina with constant density rho(x, y) = rho occupies the given region. Find the moments of inertia Ix and Iy and the radii of

jenyasd209 [6]

Answer:

Ix = Iy = $\frac{ρπR^{4} }{16}$

Radius of gyration x = y = $\frac{R}{4}$

Step-by-step explanation:

Given: A lamina with constant density ρ(x, y) = ρ occupies the given region x2 + y2 ≤ a2 in the first quadrant.

Mass of disk = ρπR2

Moment of inertia about its perpendicular axis is $\frac{MR^{2} }{2}$ . Moment of inertia of quarter disk about its perpendicular is $\frac{MR^{2} }{8}$ .
