Answer:

Answer:

t = 51

Step-by-step explanation:

Given

360 = 20√(t+273) ( divide both sides by 20 )

18 = √(t+273) ( square both sides )

18² = t + 273, that is

t + 273 = 324 ( subtract 273 from both sides )

t = 51

Alison wants to buy a mountain bike for $339.12. If she saves $28.26 each month, inhow many months will she be able to buy the bike?

Answers

To figure this out, you need to divide. So divide 339.12 by 28.26. You get 12. It will take 12 months/1 year to save up enough money.
You just need to divide 339.12 by 28.26 and you will get your answer

Can someone help me with the LxWxH of a sphere and a cylinder plz

Answers


L x W x H is what you use to find the volume of a parallelopiped ...
like a cube or a box.

Cylinders and spheres don't have lengths or widths, and spheres
don't have heights either.  The formulas for their volumes look different.

Cylinders and spheres both have a 'radius' ... that's the distance from
the center of a circle out to the curved edge of the circle.  In a cylinder,
the circle is what you see when you look at one end of it.  For the sphere,
it's just the distance from the center of the sphere to the surface, because
no matter what direction you cut the sphere, if your cut goes through the
center, then you always get the same circle.

Both formulas also involve the number called 'pi'  (PIE).  It's the number
that always pops up whenever anybody is doing anything with circles
and a lot of other things in math and science.  The thing about 'pi' is
that it's impossible to write its exact value with digits ... the decimal
part of it keeps going and going and never ends.  The beginning
of 'pi' is  3.14159 26535 89792 ... and it just keeps going forever.
In school, most teachers tell you to use 3.14  for pi.  The answers
you get aren't exactly correct, but that's not a big deal, because the
answer is never the important part of the problem in school.  The
important part is that you LEARN HOW to solve the problem and
find the answer.

In math and science writing, when pi has to be written down, it's
usually not written with digits at all.  It's usually written with the
letter from the Greek alphabet called pi.  It looks like this:  π

Now, here are the formulas you asked for, for the volumes of cylinders
and spheres:

For a cylinder:        V =  π R² H

              Volume = (pi) x (square of the radius) x (height of the cylinder)

                           square of the radius means ( R x R )


For a sphere:          V = (4/3) π R³

               Volume = (4/3) x (π) x (cube of the radius)

                                       cube of the radius means ( R x R x R )

Answer:

cylinder:        V =  π R² H

            Volume = (pi) x (square of the radius) x (height of the cylinder)

                          square of the radius means ( R x R )

sphere:         V = (4/3) π R³

              Volume = (4/3) x (π) x (cube of the radius)

                                      cube of the radius means ( R x R x R )

Ron and Pam each have 20 pennies Ron will put his pennies into 4 groups pam will put her pennies into 5 groups who will have more pennies in each group explain

Answers

Answer:

Step-by-step explanation:

Ron and Pam each have 20 pennies.

Ron will put his pennies into 4 groups.

In each group of Ron the number of pennies = (20)/(4)

                                                                          = 5 pennies

Pam will put her pennies into 5 groups.

In each group of Pam the number of pennies = (20)/(5)

                                                                            = 4 pennies

Ron will have 5 pennies in each group and Pam will have 4 pennies in each group, because Ron will make less groups of pennies than Pam.

Hence Ron will have more pennies in each group than Pam.
Ron would have more pennies in each group. This is because 20/4=5, leaving Ron with 5 pennies in 4 groups. Where as Pam would have 4 pennies in 5 groups.
