Answer:
c. 29 feet
Step-by-step explanation:
To solve this, you can substitute the second equation into the first.
It becomes 2x-(2x+3)=7
Solve from here!
You get -3=7. Not possible. Therefore there is no solution to this system.
System is inconsistent. Hope this helps.
Answer:
Step-by-step explanation:
= 12 - 3
= 9
= -8 - 4
= -12
= -60 + 12
= -48
= -2 + 2
= 0
= 17
= 1
Answer:
A). The distance covered= 5.2752 cm
B). Angle swept = 36°
C). The time = 8:45 am
Step-by-step explanation:
The watch is assumed to be a circle while the minute hand is assumed to be the radius
Radius = 1.4cm
A). From 8:13 to 8:49= 36 minutes
Recall, there is 60 minutes in a round watch.
The distance covered= 2πr*36/60
The distance covered= 2*3.14*1.4*0.6
The distance covered= 5.2752 cm
B). If distance covered is 8.8 mm
8.8 mm = 0.88cm
0.88= 2*3.14*1.4*(x/360)
0.88/(8.792)=x/360
0.1= x/360
0.1= x/360
36°= x
Angle swept = 36°
C). The time it will be if the watch started from 8:39 am and moved 36°
36/360= y/60
0.1= y/60
0.1*60= y
6 minutes= y
The time with be 8:39+6 minutes
The time = 8:45 am
