Answer:

23 in

Step-by-step explanation:

Volume of a Cube: V = a³

Step 1: Define

V = 12,167 in³

a = ?

Step 2: Solve for side length <em>a</em>

  1. <u>Substitute:</u> 12,167 = a³
  2. <u>Cube root both sides:</u> 23 = a
  3. <u>Rewrite:</u> a = 23

Step 3: Check

<em>Plug in a to verify it's a solution.</em>

  1. <u>Substitute: </u>V = (23 in)³
  2. <u>Evaluate:</u> V = 12,167 in³

Simplify each expression as much as possible, and rationalize denominators when applicable. . √36/√18= ?
tino4ka555 [31]

Answer:

√2

Step-by-step explanation:

Solving the given expression step by step:

\frac{\sqrt{36} }{\sqrt{18} } = \frac{6}{3\sqrt{2} }\ \ \ [\because \sqrt{36} = 6 \ and \ \sqrt{18} = 3\sqrt{2}] \\ = \frac{3 \times 2}{3\sqrt{2} } = \frac{ 2}{\sqrt{2} }= \sqrt{2}

We rationalize denominator and change it into a simpler form as soon as possible.

This is more a math question but no one is answering in the \"math\" section. . Compute 6.28x10^13 +6.30x10^11. Express your ans
RSB [31]
<span>The key step is to rewrite the exponential notations so that the exponent is the same. Then you can deal with the addition just as you would adding two decimals. The best way is to rewrite the number with the smaller exponent. 6.30 x 10^11 = 0.0630 x 10^13 Now you are adding 6.28 x 10^13 and 0.0630 x 10^13, and your answer is (6.28 + 0.0630) x 10^13. You can do the addition in the parentheses using the usual rules for sig dig when you add decimals. If necessary, afterward, you can rewrite the exponent again so that the mantissa is between 1 and 10.</span>

H=-16t^2+46t+6 after how many seconds will the ball hit the ground?
ANEK [815]
Ball hit the ground is when the function equals zero
0=-16t^2+46t+6
we can't factor so use quadraticformula

for
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
x=\frac{-46+/- \sqrt{46^2-4(-16)(6)} }{2(-16)}
x=\frac{-46+/- \sqrt{2116+384} }{-32}
x=\frac{-46+/- \sqrt{2500} }{-32}
x=\frac{-46+/- 50 }{-32}
x=\frac{-46+ 50 }{-32} or \frac{-46- 50 }{-32}
x=\frac{4}{-32} or x=\frac{-96}{-32}
x=-1/6 or x=3

we cannot have negative time because time starts at 0
disregard -1/6 as a possible answer


answer is after 3 seconds

9 -4n+ 3n = 8n + 3 -3
ArbitrLikvidat [17]

Answer:

Answer:

n = 1

Step-by-step explanation:

This equation is just basic alegebra.  First, combine like terms to get

9 - n = 8n.  (Because 3 - 3 = 0, and -4n + 3n = -n.)  Now the equation is much simpiler;  add n to both sides to get 9 = 9n.  Divide 9 by both sides to get that n = 1.  

You can check your answer by plugging 1 in for n.  

9 - 4(1) + 3(1) = 8(1) + 3 - 3

9 - 4 + 3 = 8 + 3 - 3

5 + 3 = 11 - 3

8 = 8

Therefore, n is proven to equal 1.  

Hope this is helpful kid sorry i went very far yesterday hope you can forgive me but Anyways here it is <3
