Step2247 [10]

Based on the amount of cheese used for the pizzas, the following are true:

a. Mai uses 2.5 ounces of cheese per pizza.
b. Mai will need 37.5 ounces for 15 pizzas.

<h3>Cheese used per Pizza. </h3>

This can be found as:

= Ounces of cheese used / Number of pizzas

= 10 / 4

= 2.5 ounces per pizza.

<h3 /><h3>Cheese needed for 15 pizzas. </h3>

= Number of pizzas x Cheese per pizza

= 15 x 2.5

= 37.5 ounces of cheese.

In conclusion, Mai needs 37.5 ounces of cheese to make 15 pizzas.

Monica [59]

Loss on the transaction is $37,000

As per given data

Cost of Cages = $206,790

Accumulated depreciation = $186,111

Selling Price = $18,611.10

Sale price of Asset is compared with the net book value of that asset to calculate the gain or loss arising from the sale of asset.

Net book value is the net value of the cost of asset and the accumulated depreciation of that asset.

Net Book Value = Cost of Cages - Accumulated depreciation

Net Book Value = $225,000 - $170,000 = $55,000

Selling Price = $18,000

Loss on Sale of asset = $55,000 - 18,000 = $37,000

Therefore,

Loss on the transaction is $37,000

<u>The equilibrium rate of return on a 1 year T-bond is 5%</u>

<u />

<h3>Equilibrium rate</h3>

This is the interest rate at which the demand meet the supply at a particular point.

<h3>Equilibrium rate of return</h3>

This is the sum of dividend yield plus the rate of capital gains.

we can also say that the equilibrium rate for a 1 year T-bond in this case is the sum of the real risk free rate and the expected inflation.

Data

Real risk free rate = 3%
Expected inflation = 2%

Hence, the equilibrium rate of return will be 3% + 2% = 5%.

From the above, the equilibrium rate of return is 5%

If there are 12 x 1023 oxygens in a sample of water, how many grams of hydrogen are in the sample?.

AveGali [126]

The amount of grams of hydrogen that are in the water sample is;

3.985 g

<h3>Avogadro's number</h3>

We are given that;

Number of moles of oxygen in a sample of water = 12 × 10²³

Now, the chemical formula of a molecule of water is H₂O. This means that for every 1 atom or molecule of oxygen, there must be 2 hydrogen atoms or molecules present.

Since Number of moles of oxygen in the sample is 12 × 10²³, then number of moles of hydrogen will be twice that = 2 × 12 × 10²³ = 24 × 10²³ moles

Now, molar mass of hydrogen is 1 g/mol and we know that;

Molar mass = Avogadro's number(6.023 × 10²³) moles

Thus;

6.023 × 10²³ moles = 1 g/mol

Thus; 24 × 10²³ moles of hydrogen = ( 24 × 10²³ × 1)/(6.023 × 10²³)

⇒ 3.985 g
