Answer:

V = 3591.4 ft³

Step-by-step explanation:

The formula for the volume of a sphere whose radius is given is

V = (4/3)πr³

Here we have V = (4/3)(3.14)(9.5 ft)³, or:

V = 3591.4 ft³

prisoha [69]

Answer:

$\large\boxed{\dfrac{2}{5}}$

Step-by-step explanation:

$\text{The product of the number and its reciprocal gives us 1.}\\\text{Reciprocal of }\ \dfrac{5}{2}\ \text{is equal}\ \dfrac{2}{5}.\\\\\dfrac{5}{2}\times\dfrac{2}{5}=\dfrac{5\!\!\!\!\diagup}{2\!\!\!\!\diagup}\times\dfrac{2\!\!\!\!\diagup}{5\!\!\!\!\diagup}=\dfrac{1}{1}\times\dfrac{1}{1}=1\times1=1$

Y is inversely proportional to x. When y=25, x=4 Work out y when x=20

ipn [44]

Answer:

y=5 when x=20

Step-by-step explanation:

Using the format for inverse proportions: y=k/x

To find k, substitute 25 in for y and 4 for x to find:

25=k/4 ⇒ k=100

Using this we can substitute k and x in for 100 and 20 to find:

y=100/20 ⇒ y=5

Write an equation of lines whose graph is parallel to the graph of y=3x-10

katrin [286]

Parallel lines have the same slope.

So the graph of [ y = 3x + any number ] is parallel
to the graph of [ y = 3x - 10 ] .

Solve for n. 3/4n = 1 3/4n - 18

Alexus [3.1K]

3/4n=1 3/4n-18

3/4n=7/4n-18

3/4n-7/4n=7/4n-18-7/4n

-n=-18

-n/-1=-18/-1

N=18
