Answer:

The answer is Ari, Beth, Cindy

Explanation

Ari

  • 2¾ miles is 2.75 miles
  • speed of 2½ miles per hour is 2.5 mi/h

DISTANCE = SPEED × TIME

t = d/s

= 2.75/2.5

= 1.1hr

= 66mins

Beth

  • 1¾ miles is 1.75 miles
  • speed of 1¼ miles per hour is 1.25 mi/h

t = d/s

= 1.75/1.25

=1.4hr

=84mins

Cindy

  • 1hr 21mins is 81mins

(Correct me if i am wrong)

If ABC=85,CBD=140 , and ,ABD=1/2x=30 find the value of x.
nexus9112 [7]
Based on the given nomenclature of angles, I think the illustration would look like that shown in the attached picture. The common vertex is point B, that's why the middle point of the given angles is B. Now, according to Angle Addition Postulate, the individual interior angles should sum up to the total angle. So, the equation would be

m∠ABD = m∠ABC + m∠CBD
m∠ABC = m∠ABD - m∠CBD
m∠ABC = 85° - m∠CBD

What is m∠2?<br> What is m∠1?
Greeley [361]

Answer:

<2 = 75

<1 = 105

Step-by-step explanation:

<2 and 75 are alternate interior angles and since the lines are parallel, they are equal

<2 = 75

<2 + <1 = 180    since the angles form a line

75+ <1 = 180

Subtract 75 from each side

<1 = 180-75

<1 = 105
