To calculate the value of the surface of a rectangular solid, we add up all of the areas of the faces of the solid. For a rectangular solid, we calculate as follows:

SA = 2lw + 2wh + 2lh
SA = 2x6x8 + 2x8x10 + 2x6x10
SA = 96 + 160 + 120
SA = 376 cm^3

Therefore, the correct answer is the second option. Hope this answers the question. Have a nice day.

Factor -3/4 out of 3/2x - 9/4y

Vikki [24]

Answer:

$-\frac{3}{4} \times (-2x +3y)$

Step-by-step explanation:

To factor out -3/4 out of that equation, multiply and divide by -3/4.

Say ;

= $\frac{3}{2}x -\frac{9}{4}y$

= $(\frac{3}{2}x -\frac{9}{4}y) \times \frac{-\frac{3}{4} }{-\frac{3}{4}}$

Now, rearranging and making necessary commutations.

= $-\frac{3}{4} \times (\frac{3}{2}x -\frac{9}{4}y) \times \frac{1 }{-\frac{3}{4}}$

= $-\frac{3}{4} \times (-2x +3y)$

Factoring -3/4 we get an equation without any fractions

= -2x + 3y

A new DVD is available for sale in a store one week after its release. The cumulative revenue, $R, from sales of the DVD in this

AnnyKZ [126]

Solution :

It is given that :

$f'(t) = (350 \ln t)'$

$=350(\ln t)'$

$=\frac{350}{t}$

So, $f(5)=350 \ln (5) \approx 563$

$f'(5) = \frac{350}{5}$

$=70$

The relative change is then,

$\frac{f'(5)}{f(5)}=\frac{70}{350\ \ln(5)}$

$=\frac{1}{5\ \ln(5)}$

$\approx 0.12$

$=12\%$

This means that after 5 weeks, the revenue from the DVD sales in $563 with a rate of change of $70 per week and the increasing at a continuous rate of 12% per week.

The sum of three consecutive integers is 312

sdas [7]

Let x be for unknown number. Let x be first number . X+1 To be second number .x+2be third number. X+(x+1)+(x+2)=312. Simplify to get 3x+3=312 . Subtract 3 from both sides 3x-3=312-3. Once you subtract get 3x=109.then divide 3 both sides . 3x/3=309/3. To get x= 103. Now once you have that First number 103. Second number 103+1=104 . And third number 103+2=105. To check add them 103+104+105=312
