What do you mean when you say what is the variable -w. Can you be more specific?
Answer:
-[b + 2.3]
or
-b - 2.3
Step-by-step explanation:
<em>I'm</em><em> </em><em>assuming</em><em> </em><em>this</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>multiple</em><em> </em><em>choice</em><em> </em><em>question</em><em> </em><em>but</em><em> </em><em>since</em><em> </em><em>you</em><em> </em><em>didn't</em><em> </em><em>list</em><em> </em><em>the</em><em> </em><em>choices</em><em> </em><em>I</em><em> </em><em>will</em><em> </em><em>just</em><em> </em><em>simplify</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>equation</em><em> </em><em>and</em><em> </em><em>hope</em><em> </em><em>for</em><em> </em><em>the</em><em> </em><em>best</em><em>.</em>
<em>The</em><em> </em><em>negatives</em><em> </em><em>sign</em><em> </em><em>in</em><em> </em><em>front</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>brackets</em><em> </em><em>is</em><em> </em><em>multiplying</em><em> </em><em>that</em><em> </em><em>quantity</em><em> </em><em>by</em><em> </em><em>-1</em><em>,</em><em> </em><em>so</em><em> </em><em>first</em><em> </em><em>we</em><em> </em><em>distribute</em><em> </em><em>the</em><em> </em><em>negative</em><em> </em><em>to</em><em> </em><em>everything</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>brackets</em><em>.</em>

To solve this problem and calculate the area of the sphere, you must apply the following formulas:
Formula N° 1:
V=4/3(πr³)
V is the volume of the sphere (V=3,000π m³).
r is the radius.
Formula N° 2:
A=4πr²
A is the area of the sphere.
r is the radius.
As you can see, you don't have the value of the radius "r". So, you must rewrite the Formula N° 1, and clear "r":
V=4/3(πr³)
(3,000)(3)=4πr²
r³=9,000/4π
r=(9,000/4π)<span>^1/3
</span> r=13.1037 m
Then, to calculate the area of the sphere, you must substitute the value of "r" into the Formula N° 2:
A=4πr²
A=4π(13.1037)²
A=2,158 m²
<span>What is the surface area of the sphere to the nearest square meter?
</span>
The answer is: 2,158 m²
Answer:
{HH,CC,HC,CH}
Step-by-step explanation:
We are given that
H denotes hot and cloudy denotes C.
We have to find the total possible outcomes for the weather on two consecutive days.
The possible cases in two consecutive days
Both days are hot=HH
Both days are cloud=CC
First day is hot other day cloudy=HC
First day is cloudy other day is hot=CH
Total possible cases=HH,CC,HC,CH
Therefor, the total outcomes for the weather on two consecutive days={HH,CC,HC,CH}
It would be 3/10 because you have to create a common denominator. That would be 10. 3x2=6 and 5x2=10, so 3/5 would become 6/10, which is equivalent. If you kept the denominators the same and subtracted the numerators, you would get 3/10.
