Is this set of numbers a Pythagorean triple? yes or no

Mathematics
1 answer:
Kaylis [27]3 years ago
8 0

<u>Answer</u>:- No.

<u>Explanation</u> :-

<u>Substitute these numbers in pythagoras theorem to check if the set of numbers is a pythagorean triplet.</u>

<u>Pythagoras theorem</u> :- sq. of hypotenuse (longest side) is equal to the sum of sq.s of other two sides.

<u>Here</u>,

hypotenuse = 12 (as it is the longest side)

and other two sides are 6 and 9.

----> 6^2 + 9^2 = 12^2

----> 36 + 81 = 144

----> 117 = 144

Since, LHS is not equal to RHS, this set of numbers is not a pythagorean triplet.

If Keira spends $45 on petrol, 1/ 9 of the money on other items and 1 /5 of the money on clothes. How much money does she spend
gogolik [260]

Answer:

The money Keira spent on food is $31.

Step-by-step explanation:

Total money spent by Keira = $45

Things Keira spent money on:

1. Clothing

2. Food

3. Other items

Money spent on Clothing = 1/5 of total money

= 1/5 x $45

Money spent on Clothing = $9

Money spent on Other Items = 1/9 of total money

= 1/9 x $45

Money spent on Other Items = $5

Money spent of on Food = Money spent - (Money spent on clothing + other items)

Money spent on food = 45 - (9+5)

= 45 - 14

Money spent on food = $31

Ivanshal [37]

Answer:

Step-by-step explanation:

731² - 631² is the difference of squares.

731² - 631² = (731+631)(731-631) = 1362×100

therefore, 731² - 631² is divisible by 100

Komok [63]
Well, if it is increasing at a fixed rate of 2 mm/s, then the volume would still be increasing at a rate of 2 mm/s when the diameter is 80 mm, if I understand your question correctly.
