Which expression does not belong with the other three? Explain your reasoning. −58−34 −34+58 −58+(−34) −34−58 This expression eq
Svetach [21]

Answer:

The expression which doesn't belong to the other three is  (-34 + 58).

Step-by-step explanation:

Given:

Four expressions.

We have to find the odd one out.

The expressions are :

  • -58-34
  • -34+58
  • -58+(-34)
  • -34-58

We know that with same signs (operator) in addition/subtraction of an expression we we add the values and the answer remains in negative.

But with different signs on numbers we will subtract the numbers and the greater number's sign will be carried forward.

So,

  • -58-34 = -92
  • -34+58 =24
  • -58+(-34) =-58-34 =-92
  • -34-58 =-92

We can see that the second expression is not equal to the other three.

(-34 + 58) is the odd one out of the four expressions.

Find the arc length of a partial circle
marusya05 [52]

Answer:

12.5664 units (rounded off to four decimal values)

Step-by-step explanation:

Arc length = 2 × π × r × \frac{central-angle}{360}

For our partial circle;

The radius (r) = 8 units

The central angle = 90°

Arc length = 2 × π × 8 × \frac{90}{360} = 12.5663706144  units

Or 12.5664 units (rounded off to four decimal values)

An angle measures 62.4° more than the measure of its supplementary angle. What is the measure of each angle?
Klio2033 [76]

Answer:

Step-by-step explanation:

If an angle measures x degrees, the measure of its supplement is (180-x) degrees.

This means that x-62.4 = 180-x, meaning that x=121.2.

So, the angles are 121.2 and 58.8 degrees.
