What is the formula for Simple Interest? ...What does each letter mean?

Mathematics
1 answer:
ella [17]2 years ago
6 0

Step-by-step explanation:

  • Simple Interest Formula
  • P = Principal Amount. I = Interest Amount. r = Rate of Interest per year in decimal; r = R/100. R = Rate of Interest per year as a percent; R = r * 100.
  • Simple interest is an application of percentage. Understanding the concept of simple interest is not only important for you to know how to solve problems in class, but also is a fundamental skill to help you manage your finances. With the basic knowledge on how the concepts work, you get empowered to make good financial decisions. In this article, we are going to learn how to calculate simple interest and the knowledge to solve real life problems. Let’s first start by defining the terms involved in simple interest.
  • The principal amount (P)
  • The principal is the money borrowed or initial amount of money deposited in a bank. The principal is denoted by a capital letter “P.”

Find the slope of the line 8x – 4y = 8\ (hint: find 2 points; then use the slope formula)
vodka [1.7K]
Or you can do the easy way

convert to slope intercept
y=mx+b
m=slope

get 1y all by itself

8x-4y=8
minus 8x both sides
-4y=-8x+8
divide both sides by -4
y=2x-2
y=mx+b
slope is 2

the hack way is
for an equatoin in standard form
ax+by=c
slope=-a/b



slope=2



if  you want to graph 2 points and do it the long way, here it is
if x=0, y=-2
if y=0, x=1
(0,-2) and (1,0)
slope=(y2-y1)/(x2-x1)
slope=(0-(-2))/(1-0)=2/1=2



slope is 2

How many milliequivalents of sodium chloride are contained with 3 L of normal saline?
AVprozaik [17]

Answer:

466mEq

Step-by-step explanation:

First, we need to know the concentration of NaCl in a normal saline solution, this is by definition 0.9%, meaning we have 0.9g of NaCl per 100ml of solution, we want to know how much NaCl we have in 3L (3000ml):

3000ml*\frac{0.9g}{100ml}=27g=27000mg

So, we have 27000mg in 3L of normal saline solution.

Now, acording to our milliequivalent (mEq) equation (mEq=\frac{mg}{pE}) where pE is de molecular mass of NaCl divided by their charges, in this case 1:

pE= \frac{23+35}{1}=\frac{58}{1} = 58

Finally we substitute in the mEq formula:

mEq=\frac{mg}{pE}=\frac{27000}{58}=466mEq

I hope you find this information useful! Good luck!

Use the distributive property to simplify this expression: 0.1(2x+3)
soldi70 [24.7K]

\huge\text{Answer:}

\huge\mathrm{0.2x+0.3}\checkmark

\huge\text{Solution:}

Hi there, hope you are having a great day! :)

<em />\bigstar\star\star\sf{What\:is\:the\:Distributive\:Property?}

The Distributive Property is a property which states that

\longmapsto\sf{a(b+c)=ab+ac

Now, let's apply this property:

\longmapsto\sf{0.1(2x+3)

\longmapsto\sf{0.2x+0.3} (Answer)

Hope you find it helpful.

Feel free to ask if you have any doubts.
