Pedro Pascal wants to have $15,000 in an account after five years. He found a bank that will offer him a 7.5% interest rate, com
Juli2301 [7.4K]

<u>Answer-</u>

He needs to put $10345 in the account today, in order to get 15000 in five years.

<u>Solution-</u>

We know that,

A=P(1+\frac{r}{n})^{nt}

Where,

A = future value of the investment with interest  = 15000

P = principal investment amount

r = annual interest rate (decimal)  = 7.5% = 0.075

n = number of times that interest is compounded per year  = 4

t = the number of years the money is invested = 5

Putting the values,

15000=P(1+\frac{0.075}{4})^{4 \times 5}

\Rightarrow P=\frac{15000}{(1+0.01875)^{20}} =\frac{15000}{1.01875^{20}} =\frac{15000}{1.45} =10344.8 \approx 10345

If 1m = 3.3 ft, how many cubic feet is the Kuroshio Sea tank? Volume is 9,450. Show your calculations!
Naddika [18.5K]

Answer:

339604.65 cubic feet

Step-by-step explanation:

We are given that 1 m is equal to 3.3 ft.

1 m = 3.3 ft

This means that if we find the volume of a cube of 1 m, we have its volume as:

1^3 = 1 m^3

In the same way, the volume of a cube of 3.3 ft (1 m) is:

3.3^3 = 35.937 ft^3

This means that:

1m^3 = 35.937 ft^3

The Kuroshio sea tank has volume of 9450 m^3. Its volume in cubic feet is therefore:

1m^3 = 35.937 ft^3\\\\9450 m^3 = 9450 * 35.937 = 339604.65 ft^3

The volume of the tank is 339604.65 cubic feet.

Show that 3650 is not a perfect square.​
KatRina [158]

Answer:

A number that is a perfect square never ends in 2, 3, 7 or 8. If your number ends in any of those numbers, you can stop here because your number is not a perfect square. Obtain the digital root of the number. The digital root essentially is the sum of all of the digits.

Step-by-step explanation:

hope this helps you super sorry if it does not

Triangle FGH is similar to JKM.
mario62 [17]

Answer: J = 14.4 cm

Step-by-step explanation:

<em>K is similar to G</em>

So we can find the scale that FHG was dilated by dividing the side length of G by the side length of K

16.56/9.2 = 1.8

So the sides of the triangle KMJ were multiplied by a factor of 1.8

to find m :

25.92/1.8 = 14.4

J = 14.4
