Answer:

h > 2

-------------------------

h < 3

Step-by-step explanation:

5h – 4 > 6

add 4 both sides

5h > 10

divide 5 both sides

h > 2

-------------------------

7h + 11 < 32

subtract 11 both sides

7h < 21

divide 7 both sides

h < 3

What are the factors of 2x^2 + 5x -12?
Andrews [41]

Answer:

(2x - 3) • (x + 4)

Step-by-step explanation:

Step  1  :

Equation at  step  1  :

 (2x2 +  5x) -  12

Step  2  :

Trying to factor by splitting the middle term

2.1     Factoring  2x2+5x-12  

The first term is,  2x2  its coefficient is  2 .

The middle term is,  +5x  its coefficient is  5 .

The last term, "the constant", is  -12  

Step-1 : Multiply the coefficient of the first term by the constant   2 • -12 = -24  

Step-2 : Find two factors of  -24  whose sum equals the coefficient of the middle term, which is   5 .

-24    +    1    =    -23  

     -12    +    2    =    -10  

     -8    +    3    =    -5  

     -6    +    4    =    -2  

     -4    +    6    =    2  

     -3    +    8    =    5

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -3  and  8  

                    2x2 - 3x + 8x - 12

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (2x-3)

             Add up the last 2 terms, pulling out common factors :

                   4 • (2x-3)

Step-5 : Add up the four terms of step 4 :

                   (x+4)  •  (2x-3)

            Which is the desired factorization

Water flows through a pipe of diameter 4cms with a velocity of
MissTica

Answer:

  1.28 m

Step-by-step explanation:

The speed at which water rises in the tank is proportional to the speed of the water in the pipe and inversely proportional to the ratio of the tank area to the pipe area.

The ratio of tank area to pipe area is the square of the ratio of their diameters:

  ((150 cm)/(4 cm))² = 1406.25

Then the rate of rise of water in the tank is ...

  (0.5 m/s)/(1406.25)

After 1 hour = 3600 seconds, the height of the water will be ...

  rise = (time)(rate of rise)

  (3600 s)(0.5 m/s)/1406.25 = 1.28 m
