Answer:

D.

Step-by-step explanation:

Firstly, we should know that there are 10 floors.

For the first five, total cost = 2.0 × 5 = 10 million usd.

Now, each of the next three floor costs 3.5 million usd, total cost here = 2.5 × 3 = 7.5 million usd

Lastly, each additional floor costs 3.5 million usd. There are only two additional floors. Their costs is 3.5 × 2 = 7 million.

Total costs = 10 + 7.5 + 7 = $24.5 million usd.

An amount of $4000 was deposted in a bank of 7% compounded quarterly for 2 years. The rate the increased to 10% and was compound
GarryVolchara [31]

Answer:

  $5599.20

Step-by-step explanation:

The quarterly interest rate for the first two years was ...

  7%/4 = 0.0175

So, the multiplier each quarter for those 8 quarters was 1+0.0175 = 1.0175. At the end of the first 8 quarters, the account value had been multiplied by ...

  1.0175^8

For the next 8 quarters, the quarterly interest rate was 10%/4 = 0.025. So at the end of those 8 quarters, the balance had been multiplied by ...

  1.025^8

Then the balance at the end of 4 years was ...

  $4000(1.0175^8)(1.025^8) ≈ $5599.20

The balance was $5599.20.

Why is it sometimes easier to open an account with a bank rather than with a credit union?
Vlada [557]

It is probably easier to open an account with a bank rather than with a credit union because most credit unions require a kind of affiliation, but banks will let anyone with money to open an account. The correct option among all the options that are given in the question is the first option or option "a".

Hope this helps!

A carousel horse travels on a circular path with a radius of 15 ft. How many feet does the horse travel over an angle of 2π3 rad
snow_lady [41]

Answer:

arc\,\,length=10\,\pi\,ft\\arc\,\,length=31.41\,ft

Step-by-step explanation:

Recall that the formula for the length of an arc of circumference is given by the formula:

arc\,\,length=\theta\,R

where \theta is the radian form of central angle subtended , and R is the radius of the circumference. What is important is to have the angle given in radians for this formula to be valid.

In our case, the angle ( \frac{2\pi}{3} ) is already in radians, so we can apply the formula directly:

arc\,\,length=\theta\,R\\arc\,\,length=\frac{2\,\pi}{3} \,(15\,ft)\\arc\,\,length=10\,\pi\,ft\\arc\,\,length=31.41\,ft
