Answer:

5c + 30

Step-by-step explanation:

An easy way to create an equivalent expression is to simplify the equation given to you. In this case, distribute 5 to all terms within the parenthesis:

5(c) = 5c

5(6) = 30

5c + 30 is an answer choice.

a person invest in 9000 in a bank. the bank pays 5% interest compounded semi annually. to the nearest tenth of a year, how long

QveST [7]

Answer:

10.1 years.

Step-by-step explanation:

It is given that,

Principal = 9000

Rate of interest = 5%

No. of times interest compounded = 2 times in an year

Amount after certain time = 14800

The formula for amount:

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

where, P is principal, r is rate of interest, n is no. of times interest compounded in an year and t is time in years.

Substitute the given values in the above formula.

$14800=9000(1+\frac{0.05}{2})^{2t}$

$\frac{14800}{9000}=(1+0.025)^{2t}$

$1.644=(1.025)^{2t}$

Taking log both sides.

$\log(1.644)=\log(1.025)^{2t}$

$\log(1.644)=2t\log(1.025)$ $[\because \log a^b=b\log a]$

$\frac{\log(1.644)}{2\log(1.025)}=t$

$t=10.066$

$t=10.1$

Therefore, the required time is 10.1 years.

7. The bottom of a circular swimming pool

mote1985 [20]

<h2>Hello!</h2>

The answer is:

1017.88 square feet are blue.

To calculate how many square feet are blue, we need to calculate the area of the bottom of the circular swimming pool.

We need to remember that we can calculate the area of any circle using the following formula:

$Area_{circle}=\pi radius^{2}$

Now, we know that the diameter of the bottom is equal to 36 feet, so, we can calculate the radius of the bottom using the following formula:

$diameter=2radius\\\\radius=\frac{diameter}{2}$

So,

$radius=\frac{36feet}{2}=18feet$

Then, calculating the area we have:

$Area_{bottom}=\pi radius^{2}=\pi 18ft^{2}=1017.88ft^{2}$

Hence, we have that 1017.88 square feet are blue.

Have a nice day!

A bottle of perfume is spherical with a diameter of 36 mm.

Dafna11 [192]

24.4 mL

By converting mm to cm, we get

1 mm = 1/10 cm

18 mm = 18/10 cm

radius (r) = 1.8 cm

To find the volume,

Volume of sphere = 4/3πr3

= 4/3π(1.8)3

Volume = 24.4 cm3

To find the capacity,

1 cm3 = 1 mL

Capacity = 24.4 mL
