The length of a rectangle is twice the width. The area of the rectangle is 80 square units. Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square? Estimate the length and width of the rectangle.
Answer:
Width of the rectangle = 6.325 units
Length of the rectangle = 12.65 units
Side length of the square the 6.325 units.
Step-by-step explanation:
The length of a rectangle is twice the width. The area of the rectangle is 80 square units.
The area of the rectangle = Length × Width
Length = 2W
80 square units = 2W × W
80 = 2W²
W² = 80/2
W² = 40
W = √40
Width of the rectangle = 6.3245553203 units
Approximately = 6.325 units
Length = 2 × Width
= 2 × 6.325
= 12.65 units
• Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square?
We you divide a rectangle into 2 squares,
The length is divided into two.
Hence, the length of the rectangle = 12.65 units
12.65 units ÷ 2 = 6.325 units.
Hence, the side length of the square the 6.325 units.

You make an initial deposit of $2,500 in an account that offers 6% simple interest per year. How much will be in the account after 4 years?
Enter the correct answer in the box.
Answer:
3100
Step-by-step explanation:
3100
The amount of money in the account that he has after 4 years will be $3100.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
A = P + (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
You make a $2,500 initial deposit into an account that pays 6% simple interest per year.
Then the amount of money in the account that he has after 4 years will be given as,
A = 2500 + (2500 x 6 x 4)/100
A = 2500 + 600
A = $3100
The amount of money in the account that he has after 4 years will be $3100.

Answer:
That's pretty much correct. A continuous function is one that has no breaks or holes. For example, 1/x+5 is not continuous (or discontinuous) because the domain does not include -5. However, I don't think it needs to necessarily have to have curves because all linear functions are continuous. Hope this helps! (I learned about this a few weeks ago in my pre-calc class lol)

Ellie bought cookies and cupcakes from Publix for $102.44. If she spent $36.44 on cookies and the cupcakes are $11 per box, which equation represents this situation?
A)11x - 36.44 = 102.44
B)102.44x + 11 = 36.44
C)11x + 36,44 = 10244
D)102.44 + 36.44x = 11
Answer:
C
Step-by-step explanation:
She spent $102.44 in total.
She spent $36.44 on cookies.
And $11 per box of cupcakes.
This means that she knows the exact amount she spent on cookies and in total so now to find out how much she spent on cupcakes, she subtracts $36.44 from $102.44($66) and then divides 66 by 11(6). So if you needed the problem solved x=6.
