Answer:

It will take him 75 minutes.

Step-by-step explanation:

Rule of three / cross-multiplication:

3 newspapers require 5 min

45 newspapers require x min

x = (45 / 3) * 5

x = 15 * 5

x = 75 min

Answer:

75 minutes

Step-by-step explanation:

3 newspapers = 5 minutes

45 newspapers = x minutes

45/3 = 15

3 x 15= 45 newspapers

5 x 15 = 75 minutes

Another way:

x= minutes

45/3= x/5

15=x/5

75=x

Solve for x.

denis-greek [22]

Answer:

$\frac{3\±\sqrt{3}}{3}$

Step-by-step explanation:

Whe have the function $3x^2-6x+2=0$

To solve this equation we must factor.

To factor, we need to find the points where the function is equal to zero. So we use the quadratic formula

$\frac{-b\±\sqrt{b^2-4ac}}{2a}$

Where:

a = 3

b = -6

c = 2

Then

$\frac{-(-6) + \sqrt{(-6)^2-4(3)(2)}}{2(3)} = \frac{3+\sqrt{3}}{3}\\\\and\\\\\frac{-(-6) - \sqrt{(-6)^2-4(3)(2)}}{2(3)}= \frac{3-\sqrt{3}}{3}$

finally the correct answer is $\frac{3\±\sqrt{3}}{3}$

we know that

Observing the graph

The domain is the quantity of yellow paint in millimeters

The domain is the interval -----> [2,10]

All real numbers greater than or equal to 2 and less than or equal to 10

therefore 2 <_ x _< 10
