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.”

Either -17 or 17
Step-by-step explanation:
One whole jar= 3/3 or 1
Set up a ratio comparing the two sets of measurements.
2 2/4 ounces of peanuts is to 2/3 of a jar as x ounces of peanuts is to 3/3 of a jar.
x= ounces in 1 whole jar
2 2/4 / 2/3= x / 3/3
cross multiply
(2 2/4 * 3/3)= (2/3 * x)
convert to improper fractions
10/4 * 3/3= 2/3x
multiply numerators; multiply denominators
(10*3)/(4*3)= 2/3x
30/12= 2/3x
divide both sides by 2/3
30/12 ÷ 2/3= x
to divide fractions, multiply by the reciprocal/inverse of 2/3
30/12 * 3/2= x
multiply numerators; multiply denominators
(30*3)/(12*2)= x
90/24= x
simplify by 6
15/4 or 3 3/4 ounces= x
ANSWER: 3 3/4 ounces can make a full jar.
Hope this helps! :)
Answer:
The answer is 80.
Step-by-step explanation:
We can get our answer using PEMDAS with the expression: (20 + 37 + 48) - ( 18 + 7) and or 105 - 25.

Answer:
c. In 2 seconds, the commuter train travels 120 feet.
Step-by-step explanation:
Given
The attached graph
Required
What does x-coordinate of 2 represents
Represent this coordinate with (x,y)
From the graph:
when 
Note that:
x = time and y = distance
So:

Which means:
At 2 seconds, the train has travelled a distance of 120ft
<em>From the list of options, (c) is correct</em>
