Let's write an inequality, such as follows: x < sqrt(50) < y. Square both sides of the equation. We get x^2 < 50 < y^2. Obviously, x is between 7 and 8. Also notice, that for integers a,b, (ab)^2/b^2, equals a^2. So let's try values, like 7.1. Using the previous fact, (7.1)^2, equals (71)^2/100. So, (7.1)^2, equals 50.41. Thus, our number is between 7 and 7.1. We find, with a bit of experimentation, that the square root of 50, is 7.07.
The correct answer is 1 7/15.
Answer:
He had $7.79.
Step-by-step explanation:
8.43 + 0.25 = 8.68
8.68 - 0.89 = 7.79
<u><em>Answer:</em></u>
The sales tax is 8%
<u><em>Explanation:</em></u>
<u>We are given that:</u>
The price of the rocket is $24 and the sales tax is $1.92
To get the percentage of the sales tax, all we have to do is divide the sales tax by the price of the rocket and then multiply the quotient by 100 (to convert the ratio to percentage)
<u>This is done as follows:</u>
% of sales tax = 
% of sales tax = 
%

Answer:
y = 14
Step-by-step explanation:
move 5y over to the left and you should get -2y +6=-18. subtract 6from both sides and you will now have -2y=-24. divide bothe sides from -2 and you will get y=14
