Answer:
Y=4cm
Step-by-step explanation:
We can use the relationship between the side length and area of a square to solve for Y. Let's call the area of the small square "A" and the area of the large square "B". From the problem statement, we know:
A = 1/9 * B
Since the area of a square is equal to the side length squared, we can substitute this relationship into the equation above:
Y^2 = 1/9 * 12^2
Solving for Y:
Y^2 = 1/9 * 144
Y^2 = 16
Y = sqrt(16)
Y = 4
So, the side length of the small square is 4 cm.

Step-by-step explanation:
17/16 is just 17 ÷ 16 use calculator to fin = 1.0625
Answer:
1.06
Step-by-step explanation:
Step 1: divide numerator (1) by the denominator (16):
1 ÷ 16 = 0.0625
Step 2: add this value to the the integer part:
1 + 0.0625 = 1.0625. So,
1 1/16 = 1.0625
TECHNOLOGY Pew Research Center released a survey that asked whether participants thought technological advancements in the future will make people’s lives better or worse. Of the people interviewed, 423 earned less than $50,000 per year and 328 earned $50,000 or more. Of those earning less than $50,000 per year, 262 thought that people’s lives would get better, and 240 of those who earned $50,000 or more thought the same. Organize the data in a two-way frequency table.
Answer:
With technology and digital communication, it's
becoming easier to communicate because people
do not have to do that initial face-to-face reaction
when they are behind a keyboard. This can be a
good or a bad thing depending on how one
chooses to communicate.

Step-by-step explanation:
From the given information, the two options of the "annual salary" category are:
Less than $50,000 per year.$50,000 or more per year.From the given information, the two options of the "opinions" category are:
People's lives would get better.People's lives would not get better.To create a two-way frequency table to visually represent the possible relationships between the two sets of categorical data:
Create a 4x4 table.Label the top row of the table with one category and the left side of the table with the other category. Label the right column "Total" and the bottom row "Total".[tex]\begin{array}{|l|c|c|c|}\cline{1-4}\vphantom{\dfrac12}&\text{Less than \$50,000}&\text{\$50,000 or more}&\text{Total}\\\cline{1-4}\vphantom{\dfrac12}\text{Lives get better}&&&\\\cline{1-4}\vphantom{\dfrac12}\text{Lives don't get better}&&&\\\cline{1-4}\vphantom{\dfrac12}\text{Total}&&&\\\cline{1-4}\end{array}[/tex]
Add the given information to the table:
[tex]\begin{array}{|l|c|c|c|}\cline{1-4}\vphantom{\dfrac12}&\text{Less than \$50,000}&\text{\$50,000 or more}&\text{Total}\\\cline{1-4}\vphantom{\dfrac12}\text{Lives get better}&262&240&\\\cline{1-4}\vphantom{\dfrac12}\text{Lives don't get better}&&&\\\cline{1-4}\vphantom{\dfrac12}\text{Total}&423&328&\\\cline{1-4}\end{array}[/tex]
From the table, we can see that of the 423 of people that earned less than $50,000 per year, 262 thought that people's live would get better.
To calculate the number of people that earned less than $50,000 per year that thought people's lives would not get better, subtract 262 from 423 and place this number in the cell in column 2, row 3.
Continue like this to fill out the rest of the table, remembering to calculate the column and row totals:

Solve 9=2x^2+3x in quadratic equation
Answer: x=-3 & x=3/2
Step-by-step explanation:
1. Simplify the expression
- Divide both sides by the same factor
9=2x^2+3x
2x^2 + 3x - 9 = 0
2. Use the quadratic formula
- Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
2x^2 + 3x - 9 = 0
a = 2
b = 3
c = -9
x = √-3±3^2−4⋅2(−9)/2⋅2
3. Simplify, again.
- Evaluate the exponent
- Multiply the numbers
- Add the numbers
- Evaluate the square root
x=−3±9/4
4. Separate the equations
- To solve for the unknown variable, separate into two equations: one with a plus and the other with a minus.
x=−3+9/4
x=-3-9/4
5. Solve
- Rearrange and isolate the variable to find each solution.

Use the number line to show 2/3 divided by 1/12
The result of 2/3 divided by 1/12 is equal to 8.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
To find the result of 2/3 divided by 1/12, we can use the following equation:
= 2/3 ÷ 1/12 = (2/3) × (12/1)
= 8
Since the multiplication of two numbers is equivalent to the division of their reciprocals, we can use the number line to represent the division as multiplication:
2/3 is located between 1/2 and 1 on the number line, and 1/12 is located between 0 and 1/10. Multiplying 2/3 by 12/1 is the same as moving 12 units to the right on the number line, which is equivalent to moving from 2/3 to 8.
So, the result of 2/3 divided by 1/12 is equal to 8.
