Answer:
Distance = rate x time or d = rt...that means time t = d/r...and we have
t = 21 km / .5 km/hr = 42 hr
Step-by-step explanation:
Answer:
1.3cm
Step-by-step explanation:
The scale from the actual coin to the photo is 8 mm to 2 cm In the photo,
converting 8mm to cm = 0.8 cm
using ratio and proportion,
if 2cm = 3.25 cm
then 0.8cm = ? less
if less then more devides.
thus ; (0.8cm ÷2cm ) × 3.25cm =
( 0.4) × 3.25cm = 1.3cm
therefore the distance across the actual coin is 1.3cm.
Step-by-step explanation:
(X+3)(2x_9)
3x+12_12=90_12
3x=90_12
3x=78
X=26°
The answer is 8...............
Answer: no solution
Step-by-step explanation:
They have the same slope which means they are parallel lines that will never cross or intersect. This mean that there is no solution
