Fifty metal spheres, each with a radius of 2 cm, are melted. The melted solution is poured into a box. What is the volume of all the melted solution. Round your answer
to the nearest tenth of a centimeter.
1675.5 cm3
837.8 cm
418.9 cm
33.5 cm
Help me please
Answers
Answer:
The first option is correct 1675.5 cm^3Step-by-step explanation:
Step one:
we are given the radius as
r=2cm, and the number of spheres is 50 in numbers
let us find the volume of one sphere and multiply the area by 50 to get the volume of the 50 spheres
Step two:
[tex]volume=4/3 \pi r^3[/tex]
[tex]volume=4/3*3.142 *2^3\\\\volume=100.5/3\\\\volume=33.5[/tex]
The volume of one sphere is 33.5in^3
Hence the volume of the 50 spheres will be
=33.5*50
=1675.7cm^3 approx.
Volume of the melted solution will be 1675.5 cm³.
Radius of each metal sphere = 2 cm
Expression for the volume of the sphere is given by,
Volume = [tex]\frac{4}{3}\pi r^{3}[/tex]
Here, r = radius of the sphere
By substituting the value of radius in the expression,
Volume = [tex]\frac{4}{3}\pi (2)^3[/tex]
= 33.51 cm³
Volume of the melted solution = Volume of 50 spheres
Volume of 50 spheres = 50 × (33.51)
= 1675.5 cm³
Therefore, Volume of the melted solution will be 1675.5 cm³.

The mean sat verbal score is 447, with a standard deviation of 95. Use the Empirical Rule to determine what percent of the score lie between 352 and 447.
Answers
Answer:
34.134%
Step-by-step explanation:
We start by calculating the z-scores
Mathematically;
z-score = (x-mean)/SD
for 352
z-score = (352-447)/95 = -95/95 = -1
For 447;
z-score = (447-447)/95 = 0/95 = 0
So the probability we want to calculate will be;
P( -1 < X < 0)
According to the emipirical rule, we want to calculate the proportion below 1 SD of the mean
According to the empirical rule, this is 34.134%

Answer:
f(g(2)) = 14g(f(-2)) = 91Step-by-step explanation:
g(2) = 4(2^2) -9 = 4(4) -9 = 7
f(7) = 7+7 = 14
f(g(2)) = 14
__
f(-2) = -2 +7 = 5
g(5) = 4(5^2) -9 = 4(25) -9 = 91
g(f(-2)) = 91
A corner store sells two kinds of baked goods: cakes and pies. A cake costs $5 and a pie costs $4. In one day, the store sold 10 baked goods for a total of $46.
a. Write a system of equations to represent this situation.
b. Show work, using substitution, to determine how many cakes were sold.
Answers
Answer:
a. The system of equations is:
c+p=10
5c+4p=46
b. 6 cakes were sold.
Step-by-step explanation:
Let p be the number of pies and c be the number of cakes then according to given statements
[tex]c+p=10\ \ \ eqn\ 1\\5c+4p=46\ \ \ eqn\ 2[/tex]
Using eqn 1
c= 10-p
Putting in eqn 2
[tex]5(10-p)+4p=46\\50-5p+4p=46\\50-p = 46\\-p=46-50\\-p=-4\\p=4[/tex]
Putting p=4 in eqn 1
[tex]c+p=10\\c+4=10\\c=10-4\\c=6[/tex]
Hence,,
a. The system of equations is:
c+p=10
5c+4p=46
b. 6 cakes were sold.

Is y=2x-1 a function?
Answers
Answer:
It is a function.
Step-by-step explanation:
By definition, a function relates each element in the domain to only one element in the range. This means that each vertical line you draw through the x-axis can intersect the function at only one point. ... y = 2x +1. This is the equation of a straight line with slope 2 and y-intercept 1, so it is a function.
A linear function is two distinct but related notions. So, y=2x-1 is also a linear function.

Step-by-step explanation:
Think of it this way. If it needs to be greater than -11, that means there is some kind of restraint. that would be in this situation, its under a square root. if you plug in -11, it should equal 0, so it has to be x+11 under square root. The second one wouldn't work since that would make it square root of -22 and thats imaginary, same thing with all the others, when you plug in -11, the last 3 would come negative. the first one is the only one that cancels the negative and gives you 0
