The number of dimes is 75 coins.
The number of nickels is 1 coin.
<u>Step-by-step explanation:</u>
It is given that,
A box contains 76 coins, only dimes and nickels.
- The 10 cent coin is called a dime.
- Let, the number of dimes be x.
- The 5 cent coin is called a nickel.
- Let, the number of nickels be y.
<u>This is represented by the system of equations :</u>
x + y = 76 -------(1)
10x + 5y = 4.90 ------(2)
Multiply eq (1) by 5 and subtract eq (2) from eq (1),
5x + 5y = 380
-<u>(10x + 5y = 4.90)</u>
<u>-5x = 375.1</u>
x = 375/5
x = 75 coins.
The number of dimes is 75 coins.
Substitute x=75 in eq (1),
y = 76 - 75
y = 1 coin.
The number of nickels is 1 coin.
Answer:
s = 10500
Step-by-step explanation:
s/5 + 125 = 2225
Our mission is to isolate s. We can first begin to do this by subtracting 125 from both sides.
s/5 + 125 - 125 = 2225 - 125
s/5 = 2100
Since s is being divided by 5, we can multiply by 5 on both sides to get s alone.
s/5 x 5 = 2100 x 5
s = 10500
The objective of Exploratory Research research is to gather preliminary information that will help define the problem and suggest hypotheses.
Exploratory Research is a methodology approach that explores research
question that have not previously been studied in depth.
The nature of experimental studies is generally frequently qualitative. However, an investigation with a big sample size might also be quantitative. Due to its open-mindedness and flexibility, it is additionally commonly referred to as interpretivism or a grounded theory method.
It is commonly employed when the subject you're examining is new, or perhaps the data collection method is challenging in certain way.
