A book is on sale for 30% off. The sale price of the book is $14. What is the original price of the book
Answers
Since $14 is the price after a 30% discount then $14 is 70% of the original price.
$14/70=x/100 (100% would be the original price)
1400=70x or 1400/70 = $20!
You can double check the work by taking 30% off the $20 (10% would be $2, 30% would then be $6) 20-6=14!

Answers
Answer:
The answer is D-16
Step-by-step explanation:
Since we have x on one side, and 49 degrees on the other, both angles are the same, so we subtract 1 from 49 to get 48, so that 3x has to equal 48. So we just divide 48 by 3 to get 16, so x = 16.

liquid is being poured at a rate of 15 gallons per minute. How fast is it being poured in liters per hour? Use the fact that one gallon is approximately 3.785 liters, and do not round your answer.
Answers
Answer:
3,406.5 litres/hr
Step-by-step explanation:
The liquid is being poured at a rate of 15 gallons per minute.
1 minute = 1/60 hour
Thus, the rate can be written as:
15 gallons pet 1/60 hour
We are told that one gallon is approximately 3.785 liters.
Thus;
15 gallons = 15 × 3.785 litres = 56.775 litres.
Thus, the rate is;
56.775 litres per 1/60 hour
We want to find in litres/hr.
By proportion, we have it as;
(56.775 ÷ 1/60)/1 = 56.775 × 60 = 3,406.5 litres/hr

a/b =root3-root2 find the value of a^2+b^2/ab
Answers
(a ² + b ²) / (ab) = a/b + b/a = (√3 - √2) + 1/(√3 - √2)
Rationalize the denominator of the second term:
1/(√3 - √2) • (√3 + √2)/(√3+√2) = (√3 + √2)/((√3)² - (√2)²) = √3 + √2
So we have
(a ² + b ²) / (ab) = (√3 - √2) + (√3 + √2) = 2√3
Write the equation in slope intercept form

The sixth term of an arithmetic sequence is 3 2 , and the twelfth term is 5 2 . What is the common difference of the arithmetic sequence? The common difference is .
Answers
The sequence has a common difference, and the common difference of the arithmetic sequence is 10/3
How to determine the common difference?The given parameters are:
T6 = 32
T12 = 52
The nth term of an arithmetic progression is:
Tn = a + (n - 1) * d
So, we have:
T6 = a + 5d = 32
T12 = a + 11d = 52
Subtract both equations
a - a + 11d - 5d = 52 - 32
Evaluate
6d = 20
Divide both sides by 6
d = 10/3
Hence, the common difference is 10/3
