Answer:
1.5 and -1.5
Step-by-step explanation:
The coordinate of A is 0. It is given that AR = 3. AR represents the distance from point A to point R. Remember that distance is always positive. So, from here we have two possibilities.
- Point R is on Right side of A i.e. at coordinate 3
- Point R is on Left side of A i.e. at coordinate -3
In both of these cases AR which is the distance from A to R will be 3.
So, if R is on Right side of A, the midpoint of AR would be:
Or if R is on Left side of A, the midpoint of AR would be:
Thus, the possible coordinates of the midpoint of AR are 1.5 and -1.5
_ sqrt 16 / 25 = - sqrt (4*4)/(5*5)
=- ( _+4/5)
=-4/5 & +4/5
Answer:
20 miles
Step-by-step explanation:
The formula for distance is
d =rt where r is the rate and t is the time
We need to convert the time to hours since the rate is in mph
15 minutes * 1 hour/ 60 minutes = 1/4 hour = .25 hours
d = (80 mph) * .25 hours
d = 20 miles
Answer:
? = 49
Step-by-step explanation:
To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.
This is all based on the fact that the two triangles must be similar triangles.
Hey!~
Log 5 + Log 2 = 1
Hope this helps and have a nice day!
