Answer:
25%
Step-by-step explanation:
there is 8 items right 8 is 100% of all items and you are trying to find out the % of wering the jeans and the red shirt.
so 8 is 100% using that 1 of 100% is 12.5%
12.5% times 2 is 25 so 25% you might wear the jeans and the red shirt
hop this helps.
Answer: 
Step-by-step explanation:
From the origin we can see to get to the point plotted we have to go down 1 and right three giving us the slope 
These are in the form of y=mx+b
b is the y-intercept and m is the slope
since the y-intercept is 0 b is 0 and isn't need leaving us with y=mx
We can put our slope into the equation giving us the answer in C
Answer:
300
Step-by-step explanation:
because you multiply 100 to the number of tens is equal 300
Given:
Nana has a water purifier that filters
of the contaminants each hour.
Water has contaminants = 
To find:
The function that gives the remaining amount of contaminants in kilograms, C(t), t hours after Nana started purifying the water.
Solution:
Let C(t) be the remaining amount of contaminants in kilograms after t hours.
Initial amount of contaminants = 
Decreasing rate is
.
Using the exponential decay model:

where,
is initial amount of contaminants, r is the decreasing rate and t is time in hours.
Substituting the values, we get


Therefore, the required function is
.
