Answer:

408.2sq inches

Step-by-step explanation:

Area of the cylindrical box = 2πr(r+h)

r is the radius  = diameter/2

r = 10/2 = 5in

h is the height = 8in

Substitute

Area of the cylindrical box  = 2(3.14)(5)(5+8)

Area of the cylindrical box = 2 * 3.14 * 5 * 13

Area of the cylindrical box  = 408.2sq inches

Let's solve your equation step-by-step.

2x /5 + 3 = x/10 - 1

Step 1: Simplify both sides of the equation.

2x /5 + 3 =  x/10 - 1

2/5x + 3 = 1/10x - 1

Step 2: Subtract 1/10x from both sides.

2/5x + 3 - 1/10x = 1/10x - 1 - 1/10x

3/10x + 3 = -1

Step 3: Subtract 3 from both sides.

3 /10x + 3 - 3 = -1 - 3

3/10x = -4

Step 4: Multiply both sides by 10/3.

(10/3) * (3/10x) = (10/3) * (-4)

x = -40/3

PLS HELP!! AND HURRY!! Find an expression for the nth term ( tn ) in each of the following sequences:
fiasKO [112]

If the pattern continues, so that each term is separated by a distance of 3, then the sequence is given by the recursive rule

\begin{cases}a_1=1\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}

From this definition, we can write a_n in terms of a_1:

a_2=a_1+3

a_3=a_2+3=(a_1+3)+3=a_1+2\cdot3

a_4=a_3+3=(a_1+2\cdot3)+3=a_1+3\cdot3

a_5=a_4+3=(a_1+3\cdot3)+3=a_1+4\cdot3

and so on, up to

a_n=a_1+(n-1)\cdot3

(notice how the subscript on <em>a</em> and coefficient on 3 add up to <em>n</em>)

or

a_n=1+3(n-1)=3n-2

Can I get help? And please give the steps to how you got your answer.
lyudmila [28]

Answer:

D

Step-by-step explanation:

First, plot the points they gave you onto a graph (shown in the attached image). The slope is the rise (units up or down from a given point) over the run (units left or right from a given point).

So the slope is 6/4 because to get from the red point to the blue point, you rise 6, and run 4. And from blue to red you rise (remember rise goes up or down) 6 and run 4. 6/4 can be simplified to 3/2 so D is your answer :)
