Select the procedure that can be used to show the converse of the

Pythagorean theorem using side lengths chosen from 2 cm, 3 cm, 4 cm, and

5 cm

Answers

Answer:

The correct option is C

Step-by-step explanation:

I attached an image that forms the complete question.

The converse Pythagorean theorem states that, "If the square of the longest side of a triangle is equal to the square of the other two sides, then the triangle is a right triangle."

That is if c is the longest side of a triangle and then a and b are the other sides, then if,

c² = a² + b², the triangle is a right triangle.

Looking at all the options, option C fits the theorem well. Because

3² + 4² = 5² implies the triangle is a right triangle and the converse theorem is established.

The option D also looks close, but it's not correct because you can just draw any two sides and put the right angle in between them. The longest is always the part of the triangle that is opposite to the right angle, 90°. If for instance, you draw 3 and 5 then put the right angle in between them, 4 will take the position of the longest side which is wrong.

Therefore, the correct option is c.

The radius r of the base of a cone is given by the equation r=(3Vπh)1/2, where V is the volume of the cone and h is the height of the cone. Find the radius of the paper cup to the nearest inch. Use 3.14 for π.

The radius is about
a___inch(es).

Answers

Answer:

1 inch.

STEP BY STEP EXPLANATION:

We are given with the following equation r=(3V/πh)^1/2. By the picture we know that "V' is volume which translated to 5 in this problem, "π" is 3.14 and "h" is out height or 4in (in the picture we get all this values).

Therefore everything that there is left is to substitute and answer.

r = (3[5]/3.14[4])^1/2 - multiply the numbers

r = (15/3.14[4])^1/2 ~ (15/12.56)^1/2 -convert the decimal into a fraction and keep going

....

I must say the answer is 1 because it's rounded it's an approx. because the exact number the problem gives us is 1.09 rounded ends up being just 1

Answer:

True, False, False, False, True, False

Step-by-step explanation:

Coordinates of A, B and C are:

A(-5, -8), B(-8, 1), C(-2, 3)

The distances AB and BC are:

AB = √(-8 + 5)² + (1 + 8)² = √9 + 81 = √90 = 9.48 ≈ 9.5BC = √(-2 + 8)² + (3 - 1)² = √36 + 4 = √40 = 6.32 ≈ 6.3

Perimeter of rectangle:

P = 2(9.5 + 6.3) = 31.6 ≈ 32

Area of rectangle:

A = 9.5*6.3 = 59.85 ≈ 60

The stock of Company A gained 5% today to $54.60. What was the opening price of
the stock in the beginning of the day?

Answers

Answer: $51.85

Step-by-step explanation:

To find the answer, you would divide $54.60 by 100. You do that to figure out the amount of money for 1%. Then you multiply 5 to figure out 5%. Lastly, you would subtract the answer by $54.60 since your finding out how much it was at the beginning of the day. Equation: $54.60 ÷100= $.546 x 5= 2.73. 54.60- 2.75 =51.85

$51.85

To find the answer, you would divide $54.60 by 100. You do that to figure out the amount of money of 1%

Then you multiply 5 to figure out 5%. Subtract the answer by $54.60 since your finding out how much it was at the beginning of the day.

Equation: $54.60 ÷100= $.546 x 5= 2.73. 54.60- 2.75 =51.85.
