Answer:
x = -7
Step-by-step explanation:
The 2 horizontal lines are parallel as given ion the problem.
The x + 97 angle is congruent to the right angle.
x + 97 = 90
x = -7
Answer:
Step-by-step explanation:
- Speed in one direction = 40 km/h
- Speed on return = x
- Average speed = 60 km/h
Let the distance be d
<u>Average speed </u>
- 2d/(d/40 + d/x) = 60
- d/40 + d/x = 2d/60
- 1/40 + 1/x = 1/30
- 1/x = 1/30 - 1/40
- 1/x = (4-3)/120
- 1/x = 1/120
- x = 120 km/h
7 + 2p = p
subtract 2p on both sides. it now leaves you with:
7= -p
divde both sides by -1.
-7 = p
Answer:

Step-by-step explanation:
The mode is the value that occurs most often in the sequence. All the numbers occur twice
Answer:
Relative Size, S, is 1584.89
Step-by-step explanation:
The equation is
Where,
- R is the measurement in Richter Scale
- S is the relative size of the earthquare
<u>It is given that in Richter Scale, an earthquake measured 3.2, so .</u>
<em>They want to know relative size, S, so we put given information in equation and solve for S:</em>
<em>Converting to exponential form, we have:</em>
<em>Rounding to nearest hundredth, we have:</em>
