128 is what percent of 640

Answers

The number 128 is 20 percent of 640.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.

Let 128 is x percent of 640.

Here, x% of 640 =128

x/100 ×640 =128

6.4x=128

x=128/6.4

x=20%

Therefore, the number 128 is 20 percent of 640.

↑ 128 is 20% of 640
Lets solve:
640 IS 100% Because its the output value of the task
So lets look for x
We got 100%=640
and x%=128
Now im going to write this out as
100% / x%=640/128
Now we just have to solve this simple equation.
(100/x)*x=(640/128)*x
-Multiply both sides of the equation by x
Now we divide both sides of the equation by 5 to get x.
100=5x
100/5=x
20=x
and
x=20
So we got our answer of 20%

Answers

Answer:

2,4,5,6

Step-by-step explanation:

$n=0,4n+6=0\implies n=-(6)/(4)=-(3)/(2)$

$6n-4=0\implies n=(4)/(6)=(2)/(3)$

n=0, $n=-(3)/(2),n=(2)/(3)$

3. $2n(6n-4)(4-6n)=0$

n=0

$6n-4=0$

$n=(4)/(6)=(2)/(3)$

$4-6n=0$

$n=(4)/(6)=(2)/(3)$

4. $n(2n+3)(3n-2)=0$

$n=0$

$2n+3=0$

$n=-(3)/(2)$

$3n-2=0$

$n=(2)/(3)$

5. $2n(2n+3)(3n-2)=0$

$n=0$

$2n+3=0$

$n=-(3)/(2)$

$3n-2=0$

$n=(2)/(3)$

6. $3n(6n+9)(9n-6)=0$

$n=0$

$6n+9=0$

$n=(-9)/(6)=-(3)/(2)$

$9n-6=0$

$n=(6)/(9)=(2)/(3)$

Emilee put 3000 in a 2 year cd paying 4% interest, compounded monthly. After 2 years, she withdrew all her money. What was the amount of the withdrawal?

Answers

Answer:

3249.43

Step-by-step explanation:

The monthly compound interest can be determined from the following formula:

$A=P*(1+r/n)^(n*t)$

Where A is the final amount after interest, P is the intital amount invested, r is the interest rate, n is number of times interest is compounded per year, and t is the time in years.

We need to express rate as abn equivalent decimal number:

$4/100=0.04$
