Answer:

Comparing a whole numbers and a decimals:

First let’s talk about the similarities of comparing whole numbers and decimals:

=> their place value always matters.

Now, let’s proceed to their differences

=> in comparing whole numbers, we don’t care about the value to the nearest decimal points or the value of ones. We always look at the highest value, not unless the highest values are all the same.

=> In comparing decimals, the value to the nearest decimal points or the tenths place value always matters.

A man standing on the roof of a building 64.0 feet high looks down to the building next door. He finds the angle of depression t
8_murik_8 [283]

Answer:

The height of the next door building is 41.7 feet

Step-by-step explanation:

* Lets study the situation in the problem

- The man standing on the roof of a building 64.0 feet high

- The angle of depression to roof of the next door building is 34.7°

- The angle of depression to the bottom of the next door building

  is 63.3°

- We need to find the height of the next door building

* Lets consider the height of the man building and the horizontal

 distance between the two building formed a right triangle and the

 angle of depression is opposite to the side which represented the

 height of the building

- Let the horizontal distance between the two buildings called x

# In the triangle

∵ The length of the side opposite to the angle of depression (63.3°)

  is 64.0

∵ The length of the horizontal distance is x which is adjacent to the

  angle of depression (63.3°)

- Use the trigonometry function tanФ = opposite/adjacent

∴ tan 63.3° = 64.0/x ⇒ use cross multiplication

∴ x (tan 63.3°) = 64 ⇒ divide both sides by (tan 63.3°)

∴ x = 64.0/(tan 63.3°)

∴ x = 32.1886 feet

- Lets use this horizontal distance to find the vertical distance between

  the roofs of the two buildings

* Lets consider the height of the vertical distance between the roofs

 of the two buildings  and the horizontal distance between the two

 building formed a right triangle and the

 angle of depression is opposite to the side which represented the

 vertical distance between the roofs of the two buildings

- Let the vertical distance between the roofs of the two buildings

 called y

# In the triangle

∵ The vertical distance between the roofs of the two buildings is y

   and opposite to the angle of depression (34.7°)

∵ The horizontal distance x is adjacent to the angle of

   depression (34.7°)

∴ tan (34.7°) = y/x

∵ x = 32.1886

∴ tan 34.7° = y/32.1886 ⇒ use the cross multiplication

∴ y = 32.1886 (tan 34.7°)

∴ y = 22.2884 ≅ 22.3 feet

∴ The vertical distance between the roofs of the two

   buildings is 22.3 feet

- The height of the next door building is the difference between the

  height of the man building and the vertical distance between the

  roofs of the two buildings

∴ The height of the next door building = 64.0 - 22.3 = 41.7 feet

How much cash flow before tax and interest is necessary to support a project if $2 million is used to pay interest, the tax rate
k0ka [10]

Answer:

The necessary cash flow is $ 7,594,936.70.

Step-by-step explanation:

To determine the cash flow necessary before taxes and interest to support the project if $ 2 million is used to pay interest, the tax rate is 21%, and equity investors require annual income of $ 4 million, the following calculation must be performed:

X - 0.21X - 2,000,000 = 4,000,000

X - 0.21X = 4,000,000 + 2,000,000

0.79X = 6,000,000

X = 6,000,000 / 0.79

X = 7,594,936.70

Therefore, the necessary cash flow is $ 7,594,936.70.
