Answer:

the cost for each drink = $2.54

Step-by-step explanation:

The statement formed a simultaneous equation :

3x + 6y = $21.12

4x + 9y = $30.41

solving simultaneously,you have that ; x = 2.54, y = 2.25

In order to answer his questions, Alonzo decided to get out his set of plastic geometry models. He has a sphere, cone, and cylin
mojhsa [17]

A. If the radius of the sphere is r, what is the height of the cylinder H=4√r

B The volume of the sphere will be V=4πr³

<h3>What is volume?</h3>

Volume is defined as the space occupied by any object in the three-Dimenions. All three parameters are required for the volume like length, width and height of cube or cuboid.

Here for the part A If the radius of the sphere is r, what is the height of the cylinder the solution will be given as:-

The Volume of sphere = Volume of cylinder

4πr³=(π÷4) r²H

H=16r

H=4√r

Hence the height of the cylinder will be H=4√r

B. The volume of the shapes will be given as:-

(1) Volume of cylinder = (π÷4)r²H

Here r= radius of the cylinder

H = height of the cylinder

(2) The Volume of the Sphere=4πr³

Here r= radius of the cylinder

(3) The Volume of cone=(1÷3)πr³l

Here r = radius of the base

l=slant height of the cone

Answer:

The first expression to be solved first will be the exponets the 6 with the tiny 2

Step-by-step explanation:

PEMDAS is an acronym for the order of operations: Parenthesis, Exponent, Multiplication/ division, addition/subtraction. You solve the equation by answering it in that order, with the / answers being done simultaneously left to right (there is probably a better way to explain this, and I’m sure other users will clarify).
