The sum of three consecutive integers is 165. What are the integers?<br> The first integer is
Dovator [93]

Answer:

x = 54

Step-by-step explanation:

Let the 3 consecutive integers be,

→ x, x + 1, x + 2

Then the equation is,

→ (x) + (x + 1) + (x + 2) = 165

The required value of x will be,

→ (x) + (x + 1) + (x + 2) = 165

→ 3x + 3 = 165

→ 3x = 165 - 3

→ x = 162/3

→ [ x = 54 ]

Hence, the first integer is 54.

What is 5^4 well it's just multiplying 5 by 5 four times
Olenka [21]
That's right !  So you're on your way to the solution.
Just follow your own suggestion.

           5  x  5  x  5  x  5  =  ?


(If you don't get 625, then go back and check your work.)

A trough is 9 feet long, and its cross section is in the shape of an isosceles right triangle with hypotenuse 2 feet, as shown a
Andrei [34K]

Answer:

1/6

Step-by-step explanation:

Given:

  • Length of the trough: 9 ft

=> The volume of the trough: V =\frac{9}{2} * (b * h) (1)

  • An isosceles right triangle with hypotenuse 2 feet

=> the other two sides of the triangle is:

= tan(45 degrees) = h/(b/2)

<=> b = 2h   substitute in (1), we have:

V = \frac{9}{2}  *(2h *h) = 9h^{2}  

Take derivative of volume with respect to time to find equation for rate of filling the trough

dV/dt = 2 * 9 *h dh/dt = 18h dh/dt

<=> dh/dt = dV/dt /(18h)

As we know that, dV/dt = 2

So, dh/dt = 2 / 18h  = 1/9h

<=> V = t * rate = 2 * 2 = 4

But V = 9h^{2}    

<=> 9h^{2}     = 4

<=> h = 2/3  

The rate is the height h feet of the water in the trough changing 2 minutes after the water begins to flow:

dh/dt = 1/(9h) = 1/(9 * 2/3) = 1/6
