For the second one 1 mph equals 1.6 km so i’m pretty sure it would be all of them
For 61 you can change it to √25/√49. √25=5 and √49=7 so it would simplify to 5/7.
Answer:
1/12
Step-by-step explanation:
The whole circumference (i.e complete circle) is an arc which measures 360°
in our case, it is given that our arc measures only 30°
the fraction of our arc of 30° to the complete circle of 360° is
30/360
= 3/36
= 1/12
.50(150)+30=$105
8(32)+12 = $268
Probly the first one it looks right
