Answer:
we express the ratio of pencil to eraser and multiply it by the number of the number of pencils and erasers. 4/5 * x=20 , so x=25, then it implies that there are 5 erasers.
If two angles are congruent, then they are at the same degree. For example, if one angle is 20 degrees, and another is 20 degrees, then they are congruent. Hope this helps!
Answer:
Option (A) will be the correct match.
Step-by-step explanation:
We are asked to find which of the given equations matches the proportional relationship.
The only option (A) matches,
It is given that a cell phone rates plan costs 6 cents per minute.
Now, 6 cents is equivalent to $0.06.
Therefore, for a call of duration x minutes the cost of the call y, in dollars, will be given by
y = 0.06x
So, option (A) will be the correct match. (Answer)
The speed of the jet stream is 4.55 miles per hour
Step-by-step explanation:
Distance of one way trip= 3000 miles
The total distance of the round trip= 6000 miles
Total time = 11 hrs
Speed of the plane = 550 miles per hr
Speed = distance/time
= 6000/11
= 545.45 miles per hour
Speed of the plane = 545.45 + speed of the jet stream
550 = 545.45 + speed of jet stream
Speed of jet stream = 4.55 miles per hour
The speed of the jet stream is 4.55 miles per hour
