When 3 is subtracted from one third of a number less than 6. Which inequality and solution represents this sitution?

kenny6666 [7]

Answer:

1/3(n) - 3 < 6; n < 27

Step-by-step explanation:

" 3 subtracted from one third of a number"

= 1/3(n) - 3

given that this is less than 6:

1/3(n) - 3 < 6

1/3(n) < 6 +3

1/3(n) < 9

n < 27

Please help me on this problem

<h2>Answer:</h2>

Total Surface Area = 375 $ft^2$

<h2>Step-by-step explanation:</h2>

You need to find the area of the ceiling, floor, the two rectangle walls and the two trapezoid walls

Area of the ceiling:

c = length * width

c = 9*6.5 = 58.5

Area of the 2 rectangle walls:

w = 2(length * width)

w = 2(9 * 8)

w = 2(72)

w = 144

Area of floor:

f = 9 * 7.5

f = 67.5

Area of the two trapezoids:

$t = 2(h * \frac{a + b}{2})$

a = 6.5

b = 7.5

h = 7.5

$t = 2(h * \frac{a + b}{2})$

$t = 2(7.5 * \frac{6.5 + 7.5}{2})$

$t = 2(7.5 * \frac{14}{2})$

$t = 2(7.5 * 7)$

$t = 2(52.5)$

$t = 105$

Total Surface Area = c + w + f + t

Total Surface Area = 58.5 + 144 + 67.5 + 105

Total Surface Area = 375 $ft^2$

Describing Key Features of a Graph of a Polynomial Function:

Diano4ka-milaya [45]

End behavior:

The parent function is: f(x) = x³, which starts (from the left side) at -∞ and ends (on the right side) at +∞.

Zeroes:

f(x) = x³ + 2x² - 8x

0 = x³ + 2x² - 8x

0 = x(x² + 2x - 8)

0 = x(x + 4)(x - 2)

0 = x 0 = x + 4 0 = x - 2

x = 0 x = -4 x = 2

Intervals:

Put the zeroes in order: -4, 0, 2

since f(x) is increasing from the left then the interval from -4 to 0 is positive and the interval from 0 to 2 is negative.

For what values of x is the expression below defined?

irakobra [83]

Answer:

x > 0

Step-by-step explanation:

Given :-

√[3x²] ÷ √[4x ]

And we need to find the value of x for which the expression is defined . The expression is ,

$:\implies$ √[3x²] ÷ √[4x]

As we can see that x is inside the squareroot. So for defining the expression the value of x should be Greater than 0 . As negative inside the squareroot will give rise to imaginary numbers.

Solution :-

$:\implies$ x > 0

In interval notation :-

$:\implies\bf x \in ( 0 , \infty)$

Therefore x should be Greater than 0 .
