Answer:
40 * x - 600 = 0
Step-by-step explanation:
The first thing is to identify the variable (x) of the equation and they will be the number of days that Leilah will take to read her flashcards. Now if you need to study 600 out of 2400, it is because you have read 1800. Therefore we have to:
2400 - 1800 = 40 * x
rearranging
40 * x - 600 = 0
The above would be the equation of the situation
The diagram included should explain this.
Answer:
P(t) = 1000e^(0.01155)t
Step-by-step explanation:
Let the population of barangay be expressed according to the exponential formula;
P(t) = P0e^kt
P(t) is the population of the country after t years
P0 is the initial population
t is the time
If barangay has 1000 initially, this means that P0 = 1000
If the population doubles after 60years then;
at t = 60, P(t) = 2P0
Substitute into the formula
2P0 = P0e^k(60)
2 = e^60k
Apply ln to both sides
ln2 = lne^60k
ln2 = 60k
k = ln2/60
k = 0.01155
Substitute k = 0.01155 and P0 into the expression
P(t) = 1000e^(0.01155)t
Hence an exponential model for barangay's population is
P(t) = 1000e^(0.01155)t
Answer:
20.
Step-by-step explanation:
This can be solved using combination technique. Since we have to choose 3 out of 6 and their order is not considered. Thus,
6 combination 3
= 6C3
= 
= 
= 
= 
= 5*4
= 20 ANSWER
x represents how many are sold. then multiply 80×3
then add your x together
then you must divide your x by 3440
8 is how many higher-priced speakers take you 8 and multiple it by 3 to get how many lower-priced speakers
you have 24 low priced speaker and 8 high priced speakers.
