Answer:
128
Step-by-step explanation:
(2³) (140/7)-32 =128
Answer:
38
Step-by-step explanation:
40 x 95/100 = 38
95 is the amount
40 is the percent that this item is off by
100 is the maximum percent the item can be off by
Another example to prove this
40 percent * 95 =
(40:100)* 95 =
(40* 95):100 =
3800:100 = 38
The answer is A: 4. This is easy once you know the order of operations, aka PEMDAS. Parentheses, exponents, multiplication/division, and addition/subtraction.
No.
The few right triangles that correspond to Pythagorean Triples (3, 4, 5, for example) will have integer-length sides. The vast majority will have at least one side that is irrational. (1, 1, √2, for example)
_____
Of course, there are an infinite number of Pythagorean Triples, and they can each be scaled by an infinite number of integer scale factors. However, the infinite number of real and irrational numbers is far greater.
