If 3/4 is the dividend and -2/5 is the divisor then what is the quotient ?
Alexxx [7]

Answer:

\dfrac{-15}{8}

Step-by-step explanation:

<h3>Fraction division:</h3>

\sf \dfrac{3}{4} \ \div \dfrac{-2}{5}

 Use KCF method.

  • Keep the first fraction.
  • Change division to multiplication
  • Flip the second fraction.

       \sf \dfrac{3}{4} \ \div \dfrac{-2}{5}=\dfrac{3}{4}*\dfrac{-5}{2}

                      \sf = \dfrac{3*(-5)}{4*2}\\\\ =\dfrac{-15}{8}

If 15 people can empty the truck in 60 minutes, how long will it take 25 people to empty the same truck.
nikklg [1K]
60 divide dos by 15 is 4, so it takes 4 minutes for each person to empty it.
25 x 4 = 100, so the answer would be 100 minutes.

Can someone help please?
Vlada [557]

Answer:

Step-by-step explanation:

Vertex of the given parabola = (1, -4)

Since, vertex form of a parabola is given by,

y = (x - h)² + k

Here (h, k) is the vertex

Now substitute the coordinates (1, -4) in the equation.

y = (x - 1)²- 4 [Vertex Form]

Further solve this equation,

y = x² - 2x + 1 - 4

y = x² - 2x - 3 [Standard form]

Further write this equation in the factored form,

y = x² - 3x + x - 3

y = x(x - 3) + 1(x - 3)

y = (x + 1)(x - 3) [Factored form]
