10% chance of burning out
100-10= 90% chance of not burning out
90% = 0.9
3 lightbulbs
0.9^3 = 0.729 = 72.9%
The probability that all 3 lightbulbs stay lit by the end of the month is 72.9%

What is the volume of a cone with a radius of 6 cm and a height of 12 cm? use 3.14 for pi. round your answer to the nearest hund
natima [27]
The answer is 452.16 cm³.
Formula to calculate the volume of cone = V = πr²x h/3
Now r = 6 cm and h = 12cm, and value of π = 3.14
By putting the values,
V = (3.14) (6)² (12/3) = (3.14)(36)(4) 
V = 452.16 cm³

What is the domain of the function?<br> O x&gt;-2<br> O x &gt; 0<br> O x &lt; 2<br> all real numbers
atroni [7]

Answer:  x > -2, which is choice A

Notice that there's a vertical asymptote at x = -2. Think of it like an electric fence. You can get closer to it, but you can't touch it.

The domain is the set of all allowed inputs of a function.

7x-8y=13 solve for y
Gala2k [10]
Get y alone
so
-8y=13-7x (by subtracting 7x from both sides)
now you still want y by itself so you divide by -8
leaving you with
y=-13/8 + 7/8

24. Seven tenths of a number plus 14 is less than forty-nine.<br>​
andriy [413]

Answer:

50. ☺️☺️

Step-by-step explanation:

I'm going to assume you need this inequality solved.

First, write it as numbers, not words.

7/10n + 14 < 49

where "n" is the unknown number.

Second, if I were you, I'd change that fraction into a decimal, as it'll make life easier later on.

7/10 = 0.7

Now, solve it like you would any other equation.

0.7n + 14 < 49

0.7n +14 - 14 < 49 - 14

0.7n < 35

0.7n ÷ 0.7 < 35 ÷ 0.7

n < 50

The answer is n < 50
