mrs_skeptik [129]

Answer:

Step-by-step explanation:

3c + 5w = 16

6c + 2w = 22

-6c - 10w = -32

6c + 2w = 22

-8w = -10

w = 10/8 = 5/4 = $1.25 per lb

3c + 5(1.25) = 16

3c + 6.25 = 16

3c = 9.75

c = $3.25 per lb

A cube fits perfectly in a sphere. If the cube has a side length of 10cm, what is the volume of the sphere? Round your answer to

Goryan [66]

Answer:

Step-by-step explanation:

Since the cube fits perfectly in the sphere, it means that the diagonal of the cube will form the diameter of the sphere. In a cube, all sides are equal. To determine the length of its diagonal, d, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Therefore,

d² = 10² + 10² = 200

d = √200 = 14.14cm

Formula for finding the volume of a sphere is expressed as

Volume = 4/3 × π × r³

Radius of sphere = diameter/2 = 14.14/2 = 7.07cm

Volume = 4/3 × π × 7.07³ = 471.19π cm³

lesya692 [45]

The answer is 8884.37 times

In many cases, B is approximately proportional to the three-quarters power of M:
 $B= M^{3/4}$

Elephant:
M1 = 4.6 mt = 4.6 * 1,000,000 g = 4,600,000 g
 $B1= 4600000^{3/4}=99327.24$

Mouse
M2 = 25 g
$B2= 25^{3/4}=11.18$

determine how many times greater the metabolic rate of an elephant is than that of a mouse:
B1/B2 = 99327.24 / 11.18 = 8884.37 times
