Answer:

i got you bro

Step-by-step explanation:

It is very easy to estimate 10% of any number - just divide by 10 by moving the decimal point one place to the left.

Once you know 10% of an amount, it is possible to find 5% by dividing the value that is 10% by 2. Adding these answers gives a quick estimate of 15%

For example: "Find 15% of 300"

10% of 300 = 30 and 30÷2=15

15% of 300 = 30+15 =45

In the same way for this question ...

Treat 89.50 as $90 Find 10%, then 5%.

#10% +5% = 9+13.50#

15% of the bill is about $13.50

About $13 dollars rounded to the nearest whole dollar and $13.40 rounded to the nearest tenth.

The two numbers have 1 as a common factor and nothing else. Hence 1 is the HCF. This proves that the HCF of any two consecutive numbers is always a one.

Two integers are relatively prime (or coprime) if there is no integer greater than one that divides them both (that is, their greatest common divisor is one). For example, 12 and 13 are relatively prime, but 12 and 14 are not.

What amount of money will accumulate to $192,400 in 6 years and 11 months at the interest rate of 5.36% compounded semi-annually

MaRussiya [10]

We will have the following:

$\begin{gathered} 192400=A(1+\frac{0.0536}{2})^{(11/12)(2)}\Rightarrow A=\frac{192400}{(1+0.0536/2)^{(11/12)(2)}} \\ \\ \Rightarrow A=183293.7505...\Rightarrow A\approx18329375 \end{gathered}$

So, the original quantity was approximately $183 293.75.
