You are planning to email to two lists. the first list has 1,200 names. the second list has 900 names. there are 150 names that

Snezhnost [94]

Answer: There are 1800 unique names from both the lists.

Explanation:

Since we have given that

there are two lists :

In First list, number of names = 1200

In Second list, number of names = 900

According to question , we have also given that

there are 150 names that appear on both lists,

So,

Number of unique names in the first list is given by

$1200-150=1050$

Number of unique names in the second list is given by

$900-150=750$

Therefore, total number of unique names is given by

$1050+750=1800$

Hence, there are 1800 unique names from both the lists.

!30 POINTS! How can I use this trapezoid to prove the Pythagorean Theorem?

stiks02 [169]

Answer:

Pythagorean Theorem: c2 = a2 + b2

Find the area by adding the areas of the three triangles. The area of a right triangle is: A = ½bh

Two triangles are identical so you can just multiply the area of the first triangle by two: 2A1 = 2(½bh) = 2(½ab) = ab.

The total area of the trapezoid is : A1 + A2 = ab + ½c2

You multiply both sides by 2 to get rid of the ½: (a2 + 2ab + b2) = 2ab + c2

You subtract out the 2ab: a2 + b2 = c2.

Then what is left is the proof: a2 + b2 = c2
