Answer:

A. 30.

Step-by-step explanation:

9 x 10^7 = 90,000,000

3 * 10^6 = 3,000,000

Dividing we get 90/3

= 30.

Answer:

A.30

Step-by-step explanation:

9 × 10^7 = 90 000 000

3 × 10^6 = 3 000 000

90 000 000 / 3 000 000 = 30

Alekssandra [29.7K]

I believe it is the ratio 3 : 1.

18 students chose the turkey sandwich.

Since the class has a total of 24 students, we can deduce that 6 students chose the vegetarian sandwich.

This gives us a ratio of 18 : 6.

When simplified, we get a ratio of 3 : 1.

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 $\frac{MR^{2} }{8}$ .

Now using perpendicular axis theorem, Ix = Iy = $\frac{MR^{2} }{16}$ = $\frac{ρπR^{4} }{16}$ .

For Radius of gyration K, equate MK2 = MR2/16, K= R/4.
