A storage tank holds 235,500 in3 of a chemical. The chemical is dispensed to completely fill 25 identical cylindrical containers, each with a radius of 5 in. What is the height of the cylindrical containers? Use 3.14 to approximate pi.

Answers

Answer 1

Answer: The volume of every of the 25 cylindrical containers is 235,500/25 = 9,420 in^3

The formula for the volume of a cylinder is:

V = π(r^2).h

Where π=3.14, r = 2.5 in, V = 9,420 in^3, so you can obtain h as:

h = V / (πr^2) = 9,420 / [(3.14) (2.5^2)] = 480 in

well it would be 12/30 but it could divide by 2 which equals 6/15 which can be divided by 3 which equals 2/5 so the answer 2/5

Louisa needs 3 liters of lemonade and punch for a picnic she has 1800 milliliters of lemonade. How much punch does she need explain how you found your answer

Answers

Louisa needs 1.2 liters or 1200 milliliters of lemonade/punch for the picnic.

In a liter, there are 1000 milliliters
In 3 liters, there are 3000 milliliters
Therefore, we can set up an equation to represent how much milliliters Louisa needs.
$3000-1800$
Solve the equation and you should get 1200 milliliters.*

*If you need the number in liters, divide 1200 by 1000 and you should get 1.2 liters

If f(x) is parallel to the line Y =3/4×+2/5
which function could be f(x)

Answers

Answer:

Any function that has the slope of 3/4

Reason:In order for the 2 functions to be parallel they must have an equal distance between them at all times ( meaning if one function has a slighty different slope, than the two will intersect and will no longer be parallel). So the only way for the two lines to be parallel is if the two functions have the same slope

A solid object was sliced to form two new objects Each of the two new objects had a circular base Which shape could not have been the original object Cone Cylinder Prism Sphere

Answers

Answer: prism.

Step-by-step explanation:

Suppose you cut the objects horizontally.

The cylinder already has a circular base, so when you cut it you will have two cylinders, both with a circular base.

The sphere when cut in a horizontal line, will lead to two halves with a circular base of the same surface.

A cone already has a circular base, so when you cut it horizontally, you will end with a smaller cone (the top part that you cut) and the bottom part, that already had a circular base.

The prism has not circular sections, so it is kinda impossible to get a circular section when you cut a prism, then the correct option is a prism, this is because this is the only shape that has some faces confirmed by parallelograms.

The answer is a prism. If you think about it when you cut a cone, cylinder, or sphere in half you get a circle. If you cut a prism you'd get a quadrilateral.
