D) 311.2 ft2
8×4=40/2=20×2=40 + 18×8=144 = 184 + (3.14)81/2=254.34/2=127.17 + 184 = 311.17 which rounds 311.2 ft2
Answer: 4 units! Just took the test!
Step-by-step explanation:
Going by the formula, Half-Life = ln(.5) / k
Half-Life = .693147 / .1205
Half-Life = 5.75 days and rounded to nearest tenth,
Half-Life = 5.8 days
Step-by-step explanation:
48 oranges in 5 minutes means she picked 48 oranges in 300 seconds.
Divide 48 by 300 to get what she would pick in one second.
This equals 0.16
Multiply 0.16 by 120 seconds [how many seconds are in two minutes].
This equals 19.2 oranges in two minutes. As she cannot pick 0.2 of an orange, she could pick 19.
Sorry, misunderstood question, answer beneath me much better.
