He is wrong.
The 10 inch cube is bigger than the 5 inch cube by 5 cm in EACH DIRECTION.
So, the 10 inch cube should be twice as big in volume by a factor of 2*2*2
=8
Okay let's see.
5 cm cube volume = 5*5*5 = 125 cc
10 cm cube volume = 10 * 10 * 10 = 1,000 cc

1,000 / 125 = 8

Calculate Income Elasticity of Demand Question Suppose that when the price of cream cheese rises by 10%, the quantity of bagels
inn [45]

Answer:

eY is positive +0.1 therefore bagels are a normal good.

Step-by-step explanation:

Given data:

when, 10% rise in cheese price,  3% fall in bagels quantity observed

when, 10% rise in income,  1% fall in bagels quantity observed

from formula for cross price elasticity of demand, determine e_{AB}

e_{AB} = \frac{(−3\%}{(10\%)} = −0.3.

As,  eAB is negative, bagels $ cream cheese are complements.

By formula for income elasticity of demand,

we find thateY= \frac{(+1\%)}{(10\%)} = +0.1.

Since eYis positive, bagels are a normal good.

Find the values forX, Y, and Z so that all the following statements are true.
kvasek [131]

Answer:

x = -36, y = 6, z = -6

Step-by-step explanation:

The requirement x/z = -z means x = -z².

The requirement x/y = z means x = yz.

These two requirements together mean yz = -z², or y = -z.

The requirements that z/2 and z/3 are integers mean that z is a multiple of 2·3 = 6. The smallest magnitude non-zero multiple is z=-6 (since we also require z < -z).

Using z=-6, we have x = -z² = -36; y = -(-6) = 6.

For some positive integer n, ...

... x = -36n², y = 6n, z = -6n.
