2 + 2 = 4 because 4 is a sum of 1-digit numbers
2 + 2 ≠ 22 because 22 is the sum of 1-digit and 2-digit numbers
Step-by-step explanation:
Lets explain some important notes:
The 1-digit number consists of one digit, 4 is a one-digit numberThe 2-digit number consists of two digits, ones digit and tens digit, 23 is a 2-digit number, the ones digit is 3 and the tens digit is 2, so its value is 20 + 3The 3-digit number consists of ones digit, tens digit and the hundreds digit, 123 is a 3-digit number, the ones digit is 3, the tens digit is 2 and the hundreds digit is 1, so its value is 100 + 20 + 3∵ 2 + 2 is the addition problem of two 1-digit numbers
∴ There sum will be 4 which is also 1-digit number
∴ 2 + 2 must be 4
∵ 22 is a two digit number
∴ Its value is 20 + 2 ⇒ not 2 + 2
∴ 2 + 2 can not be 22
2 + 2 = 4 because 4 is a sum of 1-digit numbers
2 + 2 ≠ 22 because 22 is the sum of 1-digit and 2-digit numbers

A bank offers a CD that pays a simple interest rate of 6%. How much must you put in this CD now in order to have $11 comma 700 to replace all the windows in your house in 5 years?
Answer:
You should invest US$ 9,000 in the CD to replace all the windows in your house.
Step-by-step explanation:
Let's recall that the simple interest formula is:
A = P * (1 + r * t), where,
A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
Replacing with the real value, we have:
11,700 = P * (1 + 0.06 * 5)
11,700 = P * (1.3)
P = 11,700/1.3
P = 9,000
You should invest US$ 9,000 in the CD to replace all the windows in your house in 5 years.
To calculate the initial deposit for a CD with a 6% simple interest rate in order to have $11,700 in 5 years, you can use the simple interest formula. The formula is rearranged to solve for the initial deposit amount: P = I / RT, where 'P' is the initial deposit, 'I' is the desired amount, 'R' is the interest rate, 'T' is the CD term.
Explanation:The subject of the question is about how much initial deposit you must put into a CD with a simple interest rate of 6% in order to have $11,700 in 5 years. You can find this out by using the formula for simple interest, which is I = PRT. 'I' is the interest, 'P' is the principal amount (what you want to find out), 'R' is the rate of interest, and 'T' is the time in years.
Since you want to find out 'P' (the principal amount), you'd rearrange the formula to P = I / RT. Now you substitute 'I' with $11,700, 'R' with 0.06 (6% expressed as a decimal), and 'T' with 5 years. So, P = $11,700 / (0.06 * 5). From this calculation, you'll be able to determine how much money you need to deposit now into your CD to reach your goal.

The table compares the initial amount of fuel Li Jing's car had, and the total distance she traveled using that amount, in several different occasions.
Can the total distance be represented as a function of fuel?
Fuel (liters) 1st # , Distance (kilometers) 2nd #
30 100
35 120
40 140
35 120
45 160
25 90
30 100
20 80
Yes or No and why?
Answer:
answer is yes
Step-by-step explanation:
Yes, the total distance can be represented as a function of fuel. The relationship between the two variables can be represented by a linear function. By calculating the slope and y-intercept of the line, we can determine the equation representing the total distance as a function of fuel. which is y = 4x - 20
Explanation:Yes, the total distance can be represented as a function of fuel. In this case, the fuel can be considered as the independent variable and the total distance as the dependent variable. By analyzing the table, we can observe that as the amount of fuel increases, the total distance also increases. This relationship can be represented using a linear function, since the data points seem to form a straight line.
A linear function can be written in the form y = mx + b, where y represents the total distance, x represents the amount of fuel, m represents the slope of the line (which indicates how the total distance changes with each unit of fuel), and b represents the y-intercept (which represents the initial distance when there is no fuel).
By calculating the slope of the line using two data points, we can determine the equation of the linear function. For example, using the first and second data points, we can calculate the slope as:
m = (120 - 100) / (35 - 30) = 20 / 5 = 4
With this information, we can write the function representing the total distance as a function of fuel:
y = 4x + b
To determine the value of b (the y-intercept), we can select any data point and substitute the values of x and y into the function. Let's use the first data point:
100 = 4(30) + b
Solving this equation, we find that b = -20.
Therefore, the equation representing the total distance as a function of fuel is:
y = 4x - 20

Below is a map of Yellowstone Park. The scale for the map is 1cm = 25 miles.
Mrs. Fowler went on a trip from Old Faithful to Canyon.
What is the actual distance from Old Faithful to Canyon in MILES?
A 5 miles
B 62.5 miles
C 15 miles
D 75 miles
Answer:
Option D. 75 miles
Step-by-step explanation:
Looking at the Yellowstone Park map we can see that Mrs. Folwer went from Old Faitful to the Canyon by covering a straight line of [tex]3cm[/tex].
This tells us that we do not need extra calculations to find the distance covered on the map. We also know that the map scale is given as [tex]1cm=25miles[/tex]. So similarly we do not need to do extra ratio conversions.
Thus we know that if [tex]1cm=25miles[/tex] and she covered [tex]3cm[/tex] on the map, we can just multiply covered distance with the equivalency of [tex]cm[/tex] in [tex]miles[/tex] as follow:
[tex]Distance=(3cm) (25 miles)=75miles[/tex]
Thus Mrs. Folwer's actual distance from Old Faithful to Canyon in Miles is 75 miles. (which is given in Option D.)
Blake Ewasko's charge account uses the unpaid balance method to compute the finance
charges at a monthly periodic rate of 2.15%. During the month, he charged $189.34, made a 100.00
payment, and had a $21.54 finance charge. Find Blake's new balance.
Answer:
$1,114.66
Step-by-step explanation:
Data provided in the question:
Monthly periodic rate = 2.15% = 0.0215
current Charges = $189.34
Payment made = $100.00
Finance charge = $21.54
Now,
Previous balance = Finance charges ÷ Rate
= $21.54 ÷ 0.0215
= $1001.86
Unpaid balance = Previous balance + Current charges - Payment
= $1001.86 + $189.34 - $100.00
= $1091.2
New balance = Unpaid balance × ( 1 + Rate )
= $1091.2 × ( 1 + 0.0215)
= $1,114.66
Given Information in the question:
Monthly periodic rate = 2.15% = 0.0215 Current Charges = $189.34 Payment made = $100.00 Finance charge = $21.54
Previous balance = Finance charges ÷ Rate
Previous balance = $21.54 ÷ 0.0215 Previous balance = $1001.86Unpaid balance = Previous balance + Current charges - Payment
Unpaid balance = $1001.86 + $189.34 - $100.00 Unpaid balance = $1091.2
New balance = Unpaid balance × ( 1 + Rate )
New balance= $1091.2 × ( 1 + 0.0215) New balance= $1,114.66Blake's new balance is $1114.66.
