Is 13,11,21 a right triangle

Mathematics
1 answer:
IgorLugansk [536]3 years ago
5 0

Answer:

No

Step-by-step explanation:

In order to solve this you have to use the pythagorean theorem which is a^{2}+b^{2}=c^{2}. So when you do that it becomes 13^{2}+11^{2}=21^{2}. 13 x 13 = 169. 11 x 11= 121. If you add those together you get 290. Which means it is not a right triangle because 21 x 21 = 441

The sum of two numbers is 70 and their difference is 30. Find the two numbers
ikadub [295]

Answer:

Our two numbers are 50 and 20

Step-by-step explanation:

Sum means add together

Difference means subtract each other

x + y = 70

x - y = 30

subtract from each other

2x = 100

divide both sides by 2

x = 50

our first number is 50

50 + y = 70

subtract both sides by 50

y = 20

Our two numbers are 50 and 20

A card is drawn from a​ well-shuffled deck of 52 cards. Find the probability of drawing a diamond or a spade.
AveGali [126]

Answer:

2/13

Step-by-step explanation:

For a deck of card

Total cards = 52

Total spade = 4

Total diamond = 4

pr(drawing a spade) = number of spade/total cards

pr(drawing a spade) = 4/52 = 1/13

pr(drawing a diamond)  = 4/52 = 1/13

Pr(diamond or a spade) = 1/13 + 1/13 = 2/13
