The answer would 9 cm. All of the given choices are wrong
since the measurement maybe too big or too small. Like for 9 millimeter, it
would be too small for a clothespin. While 9km is too big for a clothespin,
there is no such thing as a 9km clothespin. While 9 m is also too big. The
approximate size of a clothespin is 3 inches, when we convert it to cm, it will
be 7 cm. So 9 cm is a best approximate.
Answer:
Step-by-step explanation:
180° = π radian
1° = π/180 radian
∵ 145° = π/180 × 145
= 36π/29 radian
Answer:
Volume required = 100mL
Step-by-step explanation:
Let the volume of 30% solution required be = V mL
Amount of solute in V mL of solution = 30% of V = 0.3V...............(i)
This amount is also present in 150 mL of 20% solution
For 150 mL of 20% solution we have amount of solute = 150 mL X 20%
= 30..............(ii)
Thus equating i and ii we get
0.3V = 30
Thus V =100 mL
