77.5%
Change to decimal:-
77.5 ÷ 100 = 0.775
775/1000
31/40
77.5% = 31/40
Pyhtaorean theorem says a² + b² = c²
a² + 7² = 25²
a² + 49 = 625; subtract 49 from both sides
a² = 576; square root both sides
a = 24
The perimeter is the distance around the figure, so 7 + 24 + 25 or 56
Answer:
50%
Step-by-step explanation:
What you meant was the "commutative" property.
So we can say that when adding:
<em>"<u>Commutative</u> means that the order does not make any difference in the result."</em>
Example:
5 + 6 = 6 + 5
a + b = b + a
The commutative property does not hold for subtraction.
Example:
4 - 1 ≠ 1 - 4
a - b ≠ b - a
Ok, now does the commutative property hold true for multiplication?
2 x 3 = 3 x 2
2 x 3 x 4 = 4 x 3 x 2
Yes.
What about division?
12 ÷ 4 ≠ 4 ÷ 12
The commutative property does not hold for division.
