Answer: The answer is
Step-by-step explanation: Given that Rei is barricading a door to stop a horde of zombies by satcking boxes of books on a table in front of the door.
The weight of each box is 30 kilograms and the weight of the table with 8 boxes on the top is 310 kilograms.
So, if 'g' denotes the weight of the table alone, then we have
Therefore, the weight of the table without boxes is 70 kilograms.
Now, if 'W' is the total weight of the barricade, then it can be written as a function of 'x', the number of boxes Rei stacks on the table. The expression is as follows -
Thus, the required function is

Step-by-step explanation:
As we know, the final Amount can be calculated with the formula for compound interest,
A = P(1 + \frac{r}{n} )^{nt}
where,
A = Final Amount due
P = Initial principal amount borrowed
r = rate of interest in decimal
n = number of times applied per time period
t = total time period

Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x -----> the number of pumpkins (independent variable or input value)
y ----> the cost of the pumpkins (dependent variable or output value)
we have that
For x=4, y=11
Find the value of the constant of proportionality k
The linear equation is
