First three hours = 85 * 3 = 255
last two hours = (85/2) * 2 = 85
total cost = 340
For every 5 green picks, 2 are orange. Adding 5+2 makes 7. 21/7 = 3
There are 3 sets of 5 green 2 orange picks. So 2*3 = 6.
There should be 6 orange picks.
You can also just count. 5 + 2 = 7. Adding another 5 picks = 7 + 5 + 2 = 14. Another 5 picks, 14 + 5 + 2 = 21. Adding up the orange picks, which is the twos, we get 6.
The answer would be: 4/5 + 3/5 = 7/5 ≈ 1.4

Answer:
38cm taller
Step-by-step explanation:
jack is 178cm tall
the ladder is 280cm tall
jack standing on the ladder is 280cm taller
so 178+280=458
the tree is 420cm tall
458>420
which means that jack is now taller than the tree standing in the ladder
458-420=38
so jack is 38cm taller than the tree standing on the top of the ladder
