14 yd

Area Formula= base x height

Base = 7 yd X 2yd Height= 14 yd

Volume = Area of base x height

Answers

Answer:

The volume is 196 cubic yards

Step-by-step explanation:

Given

[tex]Base\ Area = 7yd * 2yd[/tex]

[tex]Height = 14yd[/tex]

Required

The volume

The volume is given as:

[tex]Volume = Base\ Area * Height[/tex]

Where:

[tex]Base\ Area = 7yd * 2yd[/tex]

[tex]Height = 14yd[/tex]

So, the equation becomes

[tex]Volume = 7yd * 2yd * 14yd[/tex]

[tex]Volume = 196yd^3[/tex]

Answer:

Step-by-step explanation:

Square root of 2 is irrational. This has been proven by the Pythagoreans (there is a simple proof of that).

pi is also known to be irrational although the proof is a bit more demanding.

Square root of 10 can be written as a product of square root of 5 and square root of 2, which themselves are irrational. Any product involving an irrational number is irrational

Square root of 16 = 4. 4 can be written as a fraction 4/1, or 8/2, 16/4, etc. and therefore is rational by definition.

Answers

Answer:

The answer is 729/64.

Step-by-step explanation:

I would first simplify the equation.

In the denominator, you can get rid of b^0 because that just equals 1.

For the a's in the numerator and denominator, you have to flip them so the exponents can be positive.

Equation: [tex](\frac{3ab^2}{2a^3})^2[/tex]

Now, you can subtract a and a^3. This would be 1/a^2.

Equation: [tex](\frac{3b^2}{2a^2})^2[/tex]

Now, you can square the whole equation.

Equation: [tex]\frac{9b^4}{4a^4}[/tex]

This is the simplified equation. Now you can plug in -2 and -3.

Equation: [tex]\frac{9(-3)^4}{4(-2)^4}[/tex]

Equation: [tex]\frac{9(81)}{4(16)}[/tex]

Equation: 729/64

Step-by-step explanation:

Complete question

Tom started a stamp collection with 32 stamps. Each week he added 8 stamps to his collection.

Rhea started her stamp collection with 102 stamps. Each week she gave away 6 stamps.

Write an equation to represent the number of stamps in Tom’s collection based on the number of weeks he has been collecting stamps.

Solution

Let "X" be the number of weeks for which Tom collected the stamps

The number of stamps that Tom had at the time of starting the collection [tex]= 32[/tex]

It is given that he collects 8 stamps per week

So the total number of stamps that Tom collect at the end of X weeks is
