Answer:
There are <u>250 students</u> in the 6th grade.
Step-by-step explanation:
[] Let us do "number of students" over the percentage. We will use x as the total number of students in the 6th grade.
-> 35% and 100% can be divided by 100 to become decimals
Set up a proportion:
Cross multiply:
85 = 0.34x
Divide both sides by 0.34:
250 = x
Reflexive property:
x = 250

Answer:
a) 16.82 mg
b) 24 days
Step-by-step explanation:
Formula for exponential growth is given as:
Where A is the final population
is the initial population
b is the growth factor
c is the time taken for the growth 'b'
t is the amount of time
Here, We are given the following:
= 5 mg
b = 2 (Given because it doubles)
c = 4 days
a) A = ?
Using the formula:
b) Given
A = 320 mg
t = ?
Using the above formula again:
So, the answers are:
a) 16.82 mg
b) 24 days

Step-by-step explanation:
Hey there!
To find slope, you take
In this case
y2: 6
y1: 4
x2: -3
x1: 0
Now we plug in this information
Since this is the slope, you have to add a "x"
So, the slope is
