What is the minimum whole number of packages Renna needs to remove from the elevator to meet the mass requirement?
Answers
Answer:
Part A. 37.4p ≥ 170
Part B. p ≥ 5 (rounding to the next whole)
Renna needs to remove at least 5 packages from the elevator to meet the mass requirement.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Mass limit for the elevator = 450 kg
Renna and her load of packages mass = 620 kg
Each package mass = 37.4 kg
2. Write an inequality to determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement.
Number of packages * Each package mass ≥ Renna and her load of packages mass - Mass limit for the elevator
Replacing with the values and variables we know:
p * 37.4 ≥ 620 - 450
37.4p ≥ 170
3. What is the minimum whole number of packages Renna needs to remove from the elevator to meet the mass requirement?
Solving for p in the equation above, we have:
37.4p ≥ 170
p ≥ 170/37.4
p ≥ 4.55
p ≥ 5 (rounding to the next whole)

The recommended daily amount of fiber is 30 grams.
Step-by-step explanation:
Quantity of fiber in one cup = 12 grams
It is 40% of our daily recommended amount.
Let,
x be the quantity of fiber recommended daily.
40% of x = 12
Dividing both sides by 0.4
The recommended daily amount of fiber is 30 grams.

3y=-x-3
y=-1/3x-1
So the slope of this line is -1/3.
Therefore, the slope of a perpendicular line is the negative reciprocal so it would be 3.
Final answer:
In summary, a line is perpendicular to x + 3y = -3 if its slope is 3.
Explanation:
The subject requested is about finding the slope of a line that is perpendicular to the line specified by the equation x + 3y = -3. To find the slope, we'll first have to rewrite the given equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
Rewriting x + 3y = -3, we get y = -x/3 - 1. So the slope of the given line is -1/3. Now, two lines are perpendicular if and only if the product of their slopes is -1. Therefore, the slope of the line perpendicular to the given line will be -1 / original slope = -1 / (-1/3) = 3.
Thus, the slope of a line perpendicular to the line x + 3y = -3 is 3.
