You add the time she already drove (15+10) and get 25
56-25 = 31 minutes left.
Now if the 56 minute trip includes the stop at the store, we are OK with that answer. If not, then we have to know how long she stopped at the store and add it onto 31 minutes.
Answer:
Step-by-step explanation:
$9 for 3 attendees is $3 a person or 9:3 ratio
$18 for 6 attendees still $3 a person and goes by the 9:3 ratio, it's 18:6
Answer:
Part A) The volume of the entire cone is
Part B) see the explanation
Step-by-step explanation:
Part A) we know that
The volume of a cone is equal to
where
r is the radius of the base of the cone
h is the height of the cone
In this problem triangle ABD is similar to triangle ACE
Remember that If two figures are similar, then the ratio of its corresponding sides is proportional
so
substitute the given values
solve for x
To find out the volume of the entire cone we have
substitute in the formula
Part B) How did you determine the value for x in triangle ACE
In this problem triangle ABD is similar to triangle ACE
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
so
substitute the given values and solve for x
f=1X2^6=64
First find out the number of generation, let one=n( no. of generation)
n=total time of division/time taken for one division
i.e. 2 hours = 120min/20min=6
Answer any question with this given formula
f=ix2^n where :
f=final number of bacteria
i=initial number of bacteria
n=6
f=1X2^6=64
Answer:
Solving we get
Step-by-step explanation:
We need to find solution of
Solving the inequality:
Multiply 6 with terms inside the bracket
Subtracting 12 on both sides
Adding 4x on both sides
Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >
So, after solving we get
