Looking for right triangle side a is 1 inch long,and side b is 2 inches long. What is the length of side c?

Sergeeva-Olga [200]

Answer:

$\sqrt{5}$

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

In this situation a = 1, b = 2

$1^{2} + 2^{2} = c^{2}$

1 + 4 = $c^{2}$

5 = $c^{2}$

c = $\sqrt{5}$

This is an important mathematical theorem to know. It's called the Pythagorean Theorem.

In a game, Janeesa started with 0 points. She then earned 50 points, lost 80 points and earned 10 points. Which number line show

umka2103 [35]

Answer:

-20

Step-by-step explanation:

If Jeneesa started with, 0 points and she earned 50, then she would have 50. If she lost 80 points, she would go into the negatives. She would be at -30, and when she earned 10 more points, she would be at -20.

I don't know what your options look like, but look at the one(s) with -20 at the end and figure out what one best fits my explanation (and the numbers I use)!

37. The sum of first three terms in an arithmetic progression is 24 and the sum of their squares is 224. Find the first three te

Airida [17]

Answer:

12, 8, and 4

Step-by-step explanation:

Given

a + d + a + a - d = 24

3a = 24 ⇒ [ a = 8 ]

and (a + d)² + a² + (a - d)² = 224

3a² + 2d² = 224

2d² = 224 - 192 = 32

d² = 16

[ d = ±4 ]

∴ The first three terms to A.P are

a + d = 8 + 4 = 12

a - = 8

a - d = 8 - 4 = 4

∴ Three terms are 12 , 8, and 4
