50 is 40% of what number??????

Mathematics

So a hack is we know that 20% times 5 =100% and 40 divided by 2=20 so

50=40%
divide both sides by 2
25=20%

20 times 5=100 so
multiply both sides by 5
125=100%

 All you have to do is times 100 by 50 and then divide the product: 5000 by 40 which equals 125.

how I solved it (solved for X) below:

40/100 = 50/x --> 50*100 = 40x --> 5000 = 40x --> 5000/40 = x --> 125 = x
<u></u>
KEY: <u>/ means </u><u>divide</u>  <u>* means times</u>  <u>= means equals</u>  <u>--> means "next step</u><u>"</u>

It is called cross multiplication

Step-by-step explanation: In addition, the parentheses help identify the individual addends. If adding a negative number, it is the same as subtracting. If there is a negative sign outside the parentheses, as in example c, you must distribute it: the signs of the numbers within the parentheses must be reversed when the parentheses are removed.

Please could someone please explain how i do this, much appreciated!

You want to multiply together the number of possible choices for each digit in the code.

0-9 is ten possible numbers, since repetitions are allowed (example code 2,2,2,2) there are ten possible choices per digit in the code.

10*10*10*10 = 10,000 four digit coded possible

(3×10^​2 ​​ )×(2×10^​−4 ​​ )= ​​
Alik [6]

Answer:

Step-by-step explanation:

First, lets simplify everything in the parenthesis.

(3×10^​2 ​​ )×(2×10^​−4 ​​ )= ​​

In the parenthesis, since exponents come before multiplication in the order of operations, we need to do the exponents first.

(3 • 100) • (2 • 1/10^4)

Now, we can just multiply everything from left to right to get:

6*10^-2

Or

.06
