3 / (4/9)
First, let's multiply the top and bottom by 9 to get rid of the fraction in the denominator.
27 / 4 is the final answer.
Answer:
31/9
Step-by-step explanation:
3 4/9 as an improper fraction is 31/9.
We get our answer by multiplying the denominator of the mixed numbers by its whole number and adding that answer to its numerator. We get 31, and we put that over the denominator.
3 4/9
9x3=27
27+4=31
31/9

A solution of salt and water contains 70 grams of water per 140 milliliters of the solution. If 1 mole of water weighs 16 grams, moles of water would be present in 35 milliliters of the solution. [Round off your answer to two decimal places] (4 points)
Answers
Answer:
1.09 moles.
Step-by-step explanation:
There is 70g of water in 140ml of solution.

It is given that:
Gas mileage is the number of miles you can drive on a gallon of gasoline.
A test of a new car results in 460 miles on 20 gallons of gas.
Let x be the car's gas mileage.
The value of the x can be found as follows:
x = 460/20
x = 23
20 gallons of gas and 460 miles are represented by the numbers.
Thus, the car's gas mileage is 23 if the test of a new car results in 460 miles on 20 gallons of gas.

The distance between the given points is 13 units.
We have two coordinate points A(8, -4) and B(3, 8).
We have to determine the distance between these two points.
What is the formula to find the distance between the two points on Cartesian plane ?The distance between two points -
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
According to the question, we have -
Coordinates of 1st point - A(8, -4)
Coordinates of 2nd point - B(3, 8)
Using the distance formula given -
d = [tex]\sqrt{(3-8)^{2} + (8-(-4)^{2} }[/tex]
d = [tex]\sqrt{(-5)\times (-5) + (12)\times (12)}[/tex]
d = [tex]\sqrt{25 + 144}[/tex]
d = [tex]\sqrt{169}[/tex]
d = 13 units
Therefore, the distance between the given points is 13 units.
