7 is one tenth of what number

Sloan [31]

Answer:

Explanation:

Assume that the number we are looking for is x

one tenth is interpreted into $\frac{1}{10}$

Now, we know that one tenth of the number is 7, this means that:

$\frac{1}{10}$ * x = 7

Solve for x by multiplying both sides of the equation by 10, we get:

$\frac{1}{10}$ * x * 10 = 7 * 10

x = 70

Hope this helps :)

Felix's parents opened a savings

Crazy boy [7]

The money in the Felix's account will be $6798 when he is 21.

Step-by-step explanation:

It is given that,

The amount deposited is $2000.
The account earns 6% compound interest.
It is compounded annually for 21 years.

To find the money in Felix's account after 21 years :

The formula used here is,

⇒ $A = P(1+r/n)^{nt}$

where A is the amount after 21 years.

P is the initial amount deposited ⇒ P = 2000
r is the rate ⇒ r = 0.06
n is the number of times interest is compounded per year⇒ n = 1
t is the time period ⇒ t = 21

⇒ $2000(1+0.06/1)^{21\times 1}$

⇒ $2000(1.06)^{21}$

⇒ $2000\times3.399$

⇒ $6798$

Therefore, The money in the Felix's account will be $6798 when he is 21.
