Answer:

The volume of a sphere is 2/3 times the volume of a similar cylinder

Scale factor : 2/3

Step-by-step explanation:

Let us consider a sphere of radius r. The volume of the sphere will be given as

V_{s}=\frac{4}{3} \pi r^{3}

Similarly, let us consider a cylinder with its height being twice the radius of the sphere. We will have its volume given as:

V_{c}=\pi r^{2}h

but h = 2r

Hence we have

V_{c}= 2\pi r^{3}h

We can divide the two volumes to get a constant that links them together

\frac{V_{s}}{V_{c}}=\frac{\frac{4}{3} \pi r^{3}}{2\pi r^{3}h}

this will give us 2/3

Hence the scale factor for Vol sphere: Vol cylinder is 2/3

In a population of grasshoppers, the ratio of grasshoppers with a white marking to those without a white marking is 2:3. An ento
LekaFEV [45]

Answer:

D. 116

Step-by-step explanation:

Let the grasshoppers with a white marking be 2x.

Let the grasshoppers without a white marking be 3x.

2x + 3x = 290

5x = 290

x = 290 / 5

x = 58

The grasshoppers with a white marking

= 2x

= 2 ( 58 )

= 116

The base of a triangle is given as 2b. The height of the triangle is given as 5b-7. Find an expressions for the area of the tria
Tcecarenko [31]

Answer:

Step-by-step explanation:

Area = 1/2 * 2b * (5b - 7)

Area = 1/2 * 2b * (5b - 7) = 24

b * (5b - 7) = 24

5b^2 - 7b = 24

5b^2 - 7b - 24= 0

(b- 3 )(5b + 8) = 0

b = 3                    This the only solution that works.  b can't be minus

The base is 2b or 2 * 3 = 6
