17c because you have to pair the terms
Answer:
Step-by-step explanation:
Let the time Ajay and Bala took to meet be t, speed of Ajay be a and speed of Bala be b
<u>Until they met, the distance they made:</u>
Now, the rest of the distance took Ajay 16 min and Bala 9 min.
<u>We can compare the distances as:</u>
<u>From the first equation we have:</u>
<u>From the second equation we have:</u>
<u>Comparing:</u>
- t/16= 9/t
- t² = 9*16
- t² = 144
- t = √144
- t = 12 min
<u>The meting time is:</u>
- 9:00 am + 12 min = 9:12 am
Answer:
Part a) The volume of the pill is
Part b)
Part c)
Step-by-step explanation:
Part a) Find the volume of the pill in cubic millimeters
we know that
The volume of the pill is equal to the volume of the cylinder plus the volume of a sphere (two hemisphere is equal to one sphere)
so
we have
assume
substitute
Part b) If the pill is to contain 1,000 milligrams of vitamin C, then how much vitamin C does the pill contain per cubic millimeter?
Divide 1,000 milligrams by the volume
Part c) Another pill that is entirely spherical has a diameter of 10 millimeters and contains 1.5 milligrams of vitamin C per cubic millimeter. How much less vitamin C does this second pill contain, rounded to the
nearest milligram, than the one pictured?
step 1
Find the volume of the sphere
The volume of the sphere is equal to
we have
----> the radius is half the diameter
assume
substitute
step 2
Multiply the volume by 1.5 milligrams of vitamin C per cubic millimeter
so
step 3
Find the difference
The answer is D. -3x².
If the number is a fraction, the graph gets larger.
If the number is an integer, the graph gets narrower.
