Answer:
5.09 × 10^-2
Step-by-step explanation:
You have to take the number go to the decimal and move it until you get to the first number and in this case, it is 5 put the decimal there. To write it you have to count the number of times you moved the decimal. when doing this it will always be a number times 10^ the number you moved the decimal.
<span>Answer: Option (C) Never
Explanation:
Irrational numbers are the numbers that CANNOT be written as the fraction of integers. On the other hand, integers can ALWAYS be written as a fraction.
For Example:
10 (an integer) can be written in a fraction forms as: 10/1, 100/10 etc.
Hence all integers are NEVER irrational numbers.
Information:
Few might say that although Pi (3.141592653...) is an irrational number, but we can write it as 22/7. 22/7 is mere approximation we use for the ease of calculations, NOT an accurate fraction for Pi.</span>
Answer: 14.29%
Step-by-step explanation:
Let C be the cost of 1 article and S the selling price for 1 article. The profit, P, for 1 article would be:
P = S - C
For n articles, the total profit would be
nP = nS - nC
Profit percentage would be (P/S)*100%
---------------------------------------------------------
We know that 21C = 18S: This can be written as C = (18/21)S
P = S - C
P = S - (18/21)S
P = (3/21)S or P=(1/7)S
Profit percentage would therefore be
(P/S)*100%
((1/7)S/S)*100%
(1/7)*100%
= 14.29%
