3 0

Answer:

x < 2 ∪ x > 3

Step-by-step explanation:

Rewrite 3x - 4 > 5 as 3x > 9. This tells us that x must be greater than 3.

Rewrite 8x - 10 < 6. Thus, 8x < 16 and x < 2.

The "solution set" is thus all real numbers to the left of 2 OR to the right of 3.

What is the volume of a box with a width 2 1/2 inches, length 1 3/4 inches, and height 3 1/4 inches?

enot [183]

Answer:

The volume of the box is 41.21 inches cube.

Step-by-step explanation:

Given,

Width of the box $2\frac{1}{2}$ inches

$=\frac{5}{2}$ inches

Length of the box $1\frac{3}{4}$ inches

$=\frac{7}{4}$ inches

Height of the box $3\frac{1}{4}$ inches

$= \frac{13}{4}$ inches

The box is in cuboid form.

The volume of cuboid is given by (length × breadth × height ).

So,

volume of the box is $( \frac{5}{2}$ × $\frac{7}{4}$ × $\frac{13}{4}$ $)$

= $( \frac{455}{32} )$

$= 14.21$ inches cube

The volume of the box is 41.21 inches cube.

Answer:

System utilization = 0.7 or 70%

Step-by-step explanation:

Given arrival rate of customer = 15 customer/Hour

Servie rate = $\dfrac{60}{2.8} customer/Hour$

Now, use the below formula to find the system utilization.

System utilization = $\dfrac{\text{ Arrival rate of customer }}{\text{ Servie rate}}$

System utilization = $\dfrac{15}{ \dfrac{60}{2.8}}$

System utilization = 0.7 or 70%
