50 POINTS! Which distance measures 5 units?

A number line going from negative 8 to positive 8. A closed circle appears at negative 8 and is labeled W. A closed circle appears at negative 3 and is labeled X. A closed circle appears at positive 1 and is labeled Y. A closed circle appears at positive 5 and is labeled Z. An orange arrow line extends the length of the number line and contains all points.

A. the distance between points W and X
B. the distance between points X and Y
C. the distance between points X and Z
D. the distance between points Y and Z

A. the distance between points W and X

Step-by-step explanation:

Looking for the distance of 5 units

A. the distance between points W and X

-3 - (-8) = -3 + 8 = 5Correct

B. the distance between points X and Y

1 - (-3) = 1 + 3 = 4 < 5Incorrect

C. the distance between points X and Z

5 - (-3) = 5 + 3 = 8 > 5Incorrect

D. the distance between points Y and Z

5 - 1 = 4 < 5Incorrect

Ibelieve the answer would be 7, 13, 23

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
