B, is the only solution where x=0 isn’t the answer because 2.5x+3=x and if u subtract the 2.5x you get 3= -1.5x and if you divide 3 by -1.5 it won’t be x=0

Find the length of the diameter of a sphere with a surface area of 50.27 ft^2.
Liula [17]
Sphere Surface Area     =    <span> 4 • <span>π <span>• r²

50.27 = 4 * PI * r^2
</span></span></span>
<span>50.27 / (4 * PI) = r^2

</span> <span> <span> <span> 4.0003594946 </span> </span> </span> = r^2

r = sq root (<span> <span> <span> 4.0003594946)

radius = </span></span></span> <span> <span> <span> 2.0000898716 </span> </span> </span>

So the diameter = <span> <span> <span> 4.0001797433 </span> </span> </span>

or it is roughly 4 feet

Romashka [77]

Answer:

11,880 different ways.

Step-by-step explanation:

We have been given that from a pool of 12 candidates, the offices of president, vice-president, secretary, and treasurer will be filled. We are asked to find the number of ways in which the offices can be filled.

We will use permutations for solve our given problem.

^nP_r=\frac{n!}{(n-r)!}, where,

n = Number of total items,  

r = Items being chosen at a time.        

For our given scenario n=12 and r=4.

^{12}P_4=\frac{12!}{(12-4)!}

^{12}P_4=\frac{12!}{8!}

^{12}P_4=\frac{12*11*10*9*8!}{8!}

^{12}P_4=12*11*10*9

^{12}P_4=11,880

Therefore, offices can be filled in 11,880 different ways.
