Can you form a right triangle form 21, 220, 221

1 answer:

4 0

From Pythagorean we know x^2 + y^2 = z^2. (x and y are smaller than z).

Let’s try!

21^2 + 220^2 = 441 + 48400 = 48841.

221^2 = 48841. The same!

So the answer is yes, you can make a right angled triangle.

Find the equation of the line that passes through the given points. (1, 4.5) and (3, 6)

Zanzabum

Answer:

y=0.75x+3.75

Step-by-step explanation:

The slope is

$\frac{6 - 4.5}{3 - 1} = \frac{3}{4}$

Substituting into point-slope form,

y - 6 = 0.75(x - 3)

y - 6 = 0.75x - 2.25

y = 0.75x + 3.75

Suppose 86% of 50 people at a law firm like their job. How many people like their job.

solniwko [45]

To find 86% of 50, you do 50*.86 (because .86 is the decimal form of the percentage 86%)

50*.86=43 people
