Round 429713 to the nearest thousand
Answer:43000
Step-by-step explanation:
Answer: 43000
Step-by-step explanation:
a/b =root3-root2 find the value of a^2+b^2/ab
(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

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.
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

Answer:
3x³ + 23x² + 63x + 55
Step-by-step explanation:
Given
(3x + 5)(x² + 6x + 11)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(x² + 6x + 11) + 5(x² + 6x + 11) ← distribute both parenthesis
= 3x³ + 18x² + 33x + 5x² + 30x + 55 ← collect like terms

Mia is 7.01568 x 10^6 minutes old. Convert her age to more appropriate units using years, months, and days. Assume every other month has 30 days, instead of 31.
Answer:
There are 13 years 6 months and 12 days.
Step-by-step explanation:
Let's convert the scientific notation to standard form of minutes
7.01568x10^6 =7015680 minutes
Now, let's convert this to number of days because each day has 24*60=1440 minutes.
So, number of days in 7015680 minutes is [tex]\frac{7015680}{1440}[/tex]=4872 days
Now, change this 4872 days to years, months and days.
We know 1 year has 12 months and one month has 30 days.
So,
Number of years =[tex]\frac{4872} {12*30}[/tex]=13.53333333 years
Now, convert 0.53333333 years to months.
0.53333333*12=6.4 months.
Now, convert 0.4 months to days.
0.4* 30 =12 days.
So, there are 13 years 6 months and 12 days.
A book is on sale for 30% off. The sale price of the book is $14. What is the original price of the book
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!

Find the sum of the interior angle measure of a regular polygon with 20 sides
Answer:
3240°
Step-by-step explanation:
Using the formula:
sum of interior angle = (n - 2) * 180 (where n is the number of sides)
sum of interior angle = (20 - 2) * 180
sum of interior angle = 18 * 180
sum of interior angle = 3240° ANS

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 .
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
