Answer:

Step-by-step explanation:

We can check this using the Pythagorean Theorem, $a^{2} + b^{2} = c^{2}$ .

First, we can plug our two smaller sides in for a and b, and the largest side in for c.,

$5^{2} + 20^{2} = 25^{2}$

Next, we can check the left side of the equation, which we find to be:

$5^{2} = 25\\20^{2} = 400\\$

Then, we can add these products and achieve the result of 425

Finally, we can solve the right side of the equation, which equals 625

As 425 ≠ 625, this equation fails the Pythagorean Theorem, and is therefor false.

Suppose a system of linear equations has a 3 5 augmented matrix whose fifth column is a pivot column. is the system consistent?

likoan [24]

Answer:

The system will be inconsistent.

Step-by-step explanation:

We are given that a system of linear equations has a 3×5 augmented matrix whose fifth column is a pivot column.

Then such a system is not consistent because since the augmented matrix has a pivot in fifth column it means that the new column added to the matrix A will lead to increase in the rank as that of matrix A.

Hence the rank of A and Augment A will not remain same and hence the system will be inconsistent.

For math Equations what is 4x + 5 = x + 8??

vfiekz [6]

Answer:

x = 1

Step-by-step explanation:

To solve for a variable, you need to get the variable on one side of the equation, and by itself.

4x + 5 = x + 8

4x = x + 3 --- subtract 5 from both sides

3x = 3 --- subtract x from both sides

x = 1 --- divide both sides by 3

Determine which of the following statements is NOT correct. 00:00 The equation x + 1.793 = 2.42 can be rewritten as x-1.793 = 2.

Mademuasel [1]

• x+1.793= 2.42

x-1.793= 2.42-1.793 FALSE

• 5.25x = 15.75

Solve for x, by dividing both sides of the equation by 5.25

x = 15.75/5.25

x = 3 TRUE

• The equation x = 2.4 *11.62 can be rewritten as x = 11.62 * 2.4. TRUE

• The solution to the equation x + 9.43 = 16.09 is x = 6.66.

x+9.43 = 16.09

Subtract 9.43 from both sides of the euqation:

x-9.43+9.43= 16.09-9.43

x = 6.66 TRUE

Is this correct pls help

Lyrx [107]

Answer:

Volume of round cake pan = volume of cylinder

Volume of a cylinder = $\pi r^2h$ (where r is the radius and h is the height)

Radius = $\dfrac12$ diameter ⇒ $r=\dfrac72=3.5$

⇒ volume of round cake pan = $\pi \times 3.5^2 \times 2=24.5\pi$

= 76.97 in³ (nearest hundredth)

Volume of rectangular cake pan = volume of rectangular prism

volume of rectangular prism = $wlh$ (where w is the width, l is the length and h is the height)

⇒ volume of rectangular cake pan = 6 x 9 x 2 = 108 in³

As 108 > 76.97, the rectangular cake pan has a larger volume
