36 is 0.9% of what number

Answers

Answer 1

Answer:

Answer: 4000

Step-by-step explanation:

Let the number be x.

According to the given , we have the following equation:

0.9% of x = 36

Convert 0.9% into decimal number by dividing it by 100 and replace of by multiply sign, we get

$(0.9)/(100)* x = 36$

Multiply 100 on both the sides , we get

$0.9x=3600$

Divide both the sides by 0.9 , we get

$x=4000$

Hence, the required number is 4000.

Answer 2

Answer: 0,9/100x = 36
0.009x = 36
x = 36/0.009
x = 4000

when you reverse the digits in a certain two-diget number you increase it value by 27. What is the number if the sum of its digits is 5

Answers

The number is = 10x+y
if reverse the digits, the number is: 10y+x
The sum fo its digits is = x+y=5
I suggest this system of equations:
(10y+x)-(10x+y)=27 ⇒9y-9x=27
x+y=5
We can solve this system of equations by equaliztion method
x=5-y

9y-9(5-y)=27
9y-45+9y=27
18y=27+45
18y=72
y=72/18
y=4

x=5-y
x=5-4=1

The number is: 10x+y=10(1)+4=14

Answer: the number is 14

14 or 41

41 - 14 = 37

4+1 = 5

Simplify 12 to the 16th power over 12 to the 4th power.

12^4
1^12
1^4

Answers

When dividing powers with the same base, just subtract the exponents with the same base as a single power. $Formula = a^m / a^n = a^m^-^n$

$12^1^6/12^4$

$= 12^1^6^-^4$

$=\ \textgreater \ 12^1^2$

$= 8916100448256$

12^16/12^4=12^12 answer 12 to the 12th power all you do is substract the powers 16-4=12
