15. Interpret
I'll try to explain this quick so you can sleep. Sleep is very important for brain activity and is very important to help us learn more efficiently and to help us feel more energized and healthy (and sleep is just amazing in general) :)
All of the numbers below 1000 are going to give us negative number answers. For all of them, we just subtract 1000 from it to see how much over or below we are.
February: 10
March: -5
April: 50
May: -25
June: -20

16. Analyze
An <u>integer </u>is just a number with no fraction or semi-value that is part of it. So 7 and -10 are integers while -1.5 and 2/3 are not.
A negative integer is one below zero, and a positive is one above zero.
PART A: Letters a and c represent the negative integers because they are to the left of zero on the number line.
PART B: letters b and d represent the positive integers because they are above zero on the number line.
PART C: They can be described as additive inverses, which have a different sign but the same <u>absolute value</u> (distance from zero). They are called this because when you combine them you get zero.

Enjoy your sleep and keep on learning! :D
44 because if you use the equation y=mx+b you would plug in 5.8(5)+15 which equals 44
Answer:
The cost of wasted nitric acid is $187.02
Step-by-step explanation:
Since it is given that specific gravity of Nitric Acid is 1.42 Thus the density of nitric acid is
Now from the basic relation of mass volume and density we have
Since the mass of the nitric acid is given to be 5.112 kg = 5112 grams
Thus the volume of nitric acid is
Now we know that 1000 cubic centimeters euals 1 litrer
Thus the calculated volume in liters is
Thus the cost of acid spilled equals
