Answer:
2017
Step-by-step explanation:
Molly goes every 2 years
Jerry goes every 3 years
LCM(2,3) = 2 x 3 = 6
2011 + 6 = 2017
The answer is 2017
1 litre of 10% solution contains 100mL of iodine
1 litre of 90% solution contains 900mL of iodine
Mixing them will produce 2 litres of solution containing 1000mL of iodine which is 50% iodine.
To produce 8 litres of 50% iodine they can mix 4 litres of 10% and 4 litres of 90%
Answer:
66 feet
Step-by-step explanation:
30+30=30 feet
6+6=12 yards
1 yard=3 feet
12*3=36
30+36=66
Ummm, we can't choose one of the problems if we can't see any of the problems...
2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
