A 10% increase followed by another 10% increase is not the same as a total increase of

Answer:

21%

Step-by-step explanation:

Another 10% increased means it becomes 110*110/100 = 121. The first 10% increase means the second 10% increase will be an actual 11% increase from the original, so it will be a total of 21%.

Answer:

<h2><em><u>21%</u></em></h2>

Step-by-step explanation:

Because the first 10% increase is calculated as 10% of what you started with. The second 10% is 10% of what you started with plus 10% of the increase caused by the original 10% increase.

Let's do the maths…

Let's start with 100 to make things easy.

We know that 10% of 100 is 10.

We know that 20% of 100 is 20.

So if we increase 100 by 10% we get 110.

If we increase 100 by 20% we get 120.

Now lets do the 10% plus 10%.

From the first 10% increase we were left with 110.

Now if we take 10% of the 110 we have 11.

<u>Add that to the 110 and we get 121.</u>

<em>This is why people are surprised how quick a lone can rise if we don't pay it off. We are paying interest on the basic sum plus interest on the interest, then interest on the interest on the interest.</em>

What does 8/7 to the power of 4 equel
cupoosta [38]

Answer:

The equivalent expression \frac{8^4}{7^4} = \frac{4096}{2401}\approx 1.71

Step-by-step explanation:

Given:

(\frac{8}{7})^4

We need to find the equivalent for given expression.

Solution:

(\frac{8}{7})^4

Now by using Law of indices which states;

(\frac{a}{b})^n= \frac{a^n}{b^n}

So applying the same in given expression we get;

\frac{8^4}{7^4}

Now we can say that;

8^4 = 8 \times 8 \times 8 \times 8

Also

7^4 = 7 \times 7 \times 7 \times 7

\frac{8^4}{7^4} = \frac{8 \times 8 \times 8 \times 8}{7 \times 7 \times 7 \times 7}

Now We know that;

8 \times 8 \times 8 \times 8 = 4096

7 \times 7 \times 7 \times 7 = 2401

On substituting we get;

\frac{8^4}{7^4} = \frac{4096}{2401}\approx 1.71

Hence The equivalent expression \frac{8^4}{7^4} = \frac{4096}{2401}\approx 1.71

If p→qp→q, and q→rq→r, then thats all it says
Angelina_Jolie [31]
Answer: then q→r

Explanation:

If p → q

and q →r , then  you can use the law of transitivity to conclude

q→r.

That is a basic law of sillogisms.

An example will help you to understand the transivity law:

Make p, stand for 3 > 3/4, q stand for 3/4 > 15 / 20, the you can conclude that 3 > 15 / 20.

3 > 3/4

3 /4 > 15 / 20

Then, 3 > 15 /20.

This is, from the fact that you know that 3 is gretar than 3/4 and that 3/4 is greater than 15/20, you can conclude that 3 > 15 / 20. That is transitivity and is a law of logic, which you can use to get conclusions.
