Step-by-step explanation:

10 times 10 times 60 = 6000

6000 - (1600 + 2000) = 2,400

Answer:

7200 $in^3$

Step-by-step explanation:

volume of the bottom + volume of the middle part + volume of the top part (I'm sorry this is so vague T-T)

$(8*60*10)+(2*40*10)+(8*20*10)= 4800+800+1600=7200$

Write a function rule to represent the sequence 0.3,0.9,1.5,2.1<br> PLease help

liraira [26]

The rule for sequence is:

$a_n=0.3+(n-1)(0.6)$

Step-by-step explanation:

To write the function rule, we have to check first whether it is an arithmetic sequence or geometric sequence

We have to find the common difference first. Common difference is the difference between two consecutive terms of a arithmetic sequence.

So,

Here

$a_1=0.3\\a_2=0.9\\a_3=1.5\\a_4=2.1\\d=a_2-a_1=0.9-0.3=0.6\\a_3-a_2=1.5-0.9=0.6$

The common difference is same so the sequence is an arithmetic sequence.

The explicit formula for an arithmetic sequence is:

$a_n=a_1+(n-1)d\\$

Putting the values of d and a_1 we get,

$a_n=0.3+(n-1)(0.6)$

Hence,

The rule for sequence is:

$a_n=0.3+(n-1)(0.6)$

How to solve: <img src="https://tex.z-dn.net/?f=log_%7B3%7D%20%28x%2B6%29%20%2B%20log_%7B3%7D%28x-6%29%20%3D%204" id="TexFormula

Shalnov [3]

Collapse the logarithms into one:

$\log_3(x+6)+\log_3(x-6)=\log_3((x+6)(x-6))=4$

Then write both sides as powers of 3:

$3^{\log_3((x+6)(x-6))}=3^4$

$(x+6)(x-6)=81$

Simplify the left side and solve for $x$ :

$x^2-36=81$

$x^2=117$

$x=\pm\sqrt{117}=\pm3\sqrt{13}$

But we're not done yet. Notice that both $x+6$ and $x-6$ are negative when $x=-3\sqrt{13}$ . We can't take the logarithm of a negative number (the result isn't real-valued, anyway), so we throw this solution out, and we're left with just

$x=3\sqrt{13}$

The perimeter of a rectangle is 510 cm. The ratio of the length to the width is 3:2. What are the dimensions of this rectangle?

Verizon [17]

The formula to find the perimeter of a rectangle is
$p = 2(l + w)$
When we put in our givens to this formula:
$510 = 2 \times (3x + 2x)$
Combine x values:
$510 = 2 \times 5x$
Simplify right side:
$510 = 10x$
Isolate x, by dividing both sides by 10:
$51 = x$
To find length:
$l = 3x = 3 \times 51 = 153$
For width:
$w = 2x = 2 \times 51 = 102$
To solidify our answers:
$p = 2(l + w) = 2 \times (153 + 102) = 2 \times 255 = 510$
So, our length is 153, our width is 102.
