Answer:
3 is a whole number while 2/3 is less than 3
Step-by-step explanation:
For this case we have the following numbers:
3.1 × 10-2
2.01 × 10-3
4.2 × 10-5
1.03 × 10-1
2.32 × 10-4
To order the numbers, we must look at the exponent. The greater the exponent, the greater the number.
We have then that the order of greatest to least is:
1.03 × 10-1
3.1 × 10-2
2.01 × 10-3
2.32 × 10-4
4.2 × 10-5
Answer:
Step-by-step explanation:
i will choose a
Answer:
Step-by-step explanation:
The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = .
In the equation you'd write that as r = which can be simplified to .
You end up with and you simplify this by doing , ending with the result of .

Answer:
8 sides
Step-by-step explanation:
let x be the exterior angle then 3x is the interior angle
interior angle + exterior angle = 180° , then
x + 3x = 180
4x = 180 ( divide both sides by 4 )
x = 45
the sum of the exterior angles of a polygon = 360°
since the polygon is regular with each exterior angle = 45°, then
number of sides = 360° ÷ 45° = 8
