Answer:
- Yes it is a right triangle
- The side lengths satisfy the Pythagorean theorem equation
Step-by-step explanation:
We can test these numbers to see if they satisfy the Pythagorean theorem equation:
15² = 9² + 12²
225 = 81 + 144 . . . . true
Since the numbers satisy the Pythagorean theorem relation, they belong to a right triangle.
____
You can recognize that the ratio of side lengths is ...
9 : 12 : 15 = 3 : 4 : 5
Further, you can recognize that the side lengths 3, 4, 5 belong to the right triangle with the smallest integer side lengths that satisfy the Pythagorean theorem. Hence the 9 : 12 : 15 triangle is similar (by a scale factor of 3) to a right triangle, thus is a right triangle.
Answer:
The number is 133.5
Step-by-step explanation:
Let the number = x
2/3 * x = 89 Multiply by 3
2x = 89 * 3 Combine
2x = 267 Divide by 2
x = 133.5
Answer:
1,436.75 cubic millimeters
Or
1,436 cubic millimeters
Step-by-step explanation:
Find the common factor in the fractions by multiplying the bottom numbers together
1/3 3/4
4*3
1 4/12 +x = 3 9/12
3 9/12 - 1 4/12
2 5/12 =x
A would be your answer
Answer:
Step-by-step explanation:
63= 3 * 3 * 7
63 will come in 7th table. 7*9. here 7 is a prime and 9 is composite number. 3*3 = 9. So 63 = 3*3*7
