Determine the quotient of 3/5 and 2/3

Answers

The quotient of 3/5 and 2/3 is 9/10 and this can be determined by using the arithmetic operations.

Given :

Number 1 - 3/5

Number 2 - 2/3

The following steps can be used to determined the quotient of 3/5 and 2/3:

Step 1 - First, divide 3/5 by 2/3.

=((3)/(5))/((2)/(3))

Step 2 - Now, multiply 3/5 and 3/2.

=(3)/(5)* (3)/(2)

Step 3 - Multiply 3 and 3 in the above expression.

=(9)/(5* 2)

Step 4 - Multiply 5 and 2 in the above expression.

=(9)/(10)

The quotient of 3/5 and 2/3 is 9/10 and this can be determined by using the arithmetic operations.

Answer:

The result is (9)/(10)

Step-by-step explanation:

Below are the steps to divide fractions:

  1. The 1st fraction remains untouched.
  2. The division sign turns into a multiplication sign.
  3. Flip the 2nd fraction over (finding its reciprocal)
  4. Multiply the numerators (top numbers) together
  5. Multiply the denominators (bottom numbers) together.
  6. Simplify the resulting fraction by dividing both numerator and denominator by the same number.

Let's follow the above steps:

Steps 1, 2 and 3 can be done together.

(3)/(5):(2)/(3) = (3)/(5).(3)/(2)

As you can see, we leave 1st fraction alone, change division sign (:) by multiplication sign (.), and flip 2nd fraction over.

Now, we can do steps 4 and 5...

(3)/(5):(2)/(3) = (3)/(5).(3)/(2) = (3.3)/(5.2) = (9)/(10)

Finally, step 6, we cannot simplify the resulting fraction since both numerator and denominator have no common factors.

9 = 3 . 3

10 = 2 . 5

Find the missing coefficient. -___________ y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0

Answers

Answer:

Missing Coefficient is -8

Step-by-step explanation:

We are given, _y² - [ -5y - y( -7y -9) ] - [ -y(15y + 4) ] = 0

We have to find missing value.

let missing value be a

ay² - [ -5y - y( -7y - 9) ] - [ -y(15y + 4) ] = 0

ay² - [ -5y + 7y² + 9y ] - [ -15y² - 4y ] = 0

ay² - [ 7y² + 4y ] + 15y² + 4y = 0

ay² - 7y² - 4y + 15y² + 4y = 0

ay² - 7y² + 15y² + 4y - 4y = 0

( a - 7 + 15 )y² = 0

RHS can be written as

( a - 7 + 15 )y² = 0.y²

Now comparing coefficient of both sides we get,

a - 7 + 15 = 0

a + 8 = 0

a = -8

Therefore, Missing Coefficient is -8

the speed a car travels is inversely proportional to the time it takes to complete a 100 mile trip. which of the following graphs best represents this situation

Answers

Answer:

Inversely proportion states that a relationship between two variables in which the product is a constant.

If one of the variable increases, then the other decreases in proportion so that the product is unchanged.

If y is inversely proportional to x, then the equation is of the form

y = (k)/(x) ;  where k is the constant proportionality.

As per the given condition: Speed of a car is inversely proportional to the time it takes to complete a 100 mile trip,

Let x represents the speed of car and y represents the time taken.

From the given condition:

x \propto (1)/(y)

Then by definition of inversely proportional;

x = (k)/(y)         [Since, speed = (Distance)/(Time) ]

Here, k represents the distance(i.e constant) = 100 miles.

therefore, the equation becomes now;

x = (100)/(y) or

xy = 100

The following graph for the above equation as shown below :
