Two consecutive whole numbers that 106 square root lies between
Answers
If you are unable to use a calculator or don't have one, then you can list out the set of perfect squares: {1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121}
We can see that 106 lies between 100 and 121
100 = 10^2
121 = 11^2
so that shows the square root of 106 lies between 10 and 11
The square root of 106 is between 10 and 11. So, the two consecutive whole numbers are 10 and 11.
Explanation:The student is asking about the whole numbers that the square root of 106 lies between. To determine this, we calculate the square roots of numbers near 106. The square root of 100 is 10 and the square root of 121 is 11. Therefore, the square root of 106 lies between 10 and 11. So, the two consecutive whole numbers that the square root of 106 lies between are 10 and 11.

A popular chain of superstore makes 30.479×10730.479×107 dollars in profit each year. One of its store makes 210.2×104210.2×104 in profit each year.
How many times greater is the profit made by the chain than by one of its store?
Enter your answer, using scientific notation, in the boxes.
Answers
Final answer:
To find how many times greater the chain's profit is than one store's, divide the chain's profit by the store's profit. After dividing the coefficients (30.479/210.2) and subtracting the exponents (7-4), we find that the chain's profit is 145 times greater than that of one store, which is 1.45 × 10² in scientific notation.
Explanation:
To determine how many times greater the profit made by the chain is than by one of its store, we need to divide the total profit of the chain by the profit of one store. Both profits are given in scientific notation as follows:
Chain's annual profit: 30.479 × 107 dollars
One store's annual profit: 210.2 × 104 dollars
To perform the division, we divide the coefficients and subtract the exponents:
(30.479 × 107) / (210.2 × 104) = (30.479 / 210.2) × 10(7 - 4)
Calculating the division of coefficients and exponents separately:
Coefficients: 30.479 / 210.2 ≈ 0.145
Exponents: 103, since 7 - 4 = 3
The result is:
0.145 × 103, which is the same as 1.45 × 102 in scientific notation after adjusting the decimal point one place to the right. Therefore, the chain's profit is 145 times greater than the profit of one store.

How do I solve this?
Answers
2. Set the inside of the absolute value equal to positive and negative of the right side and solve both equations. Very often you get two solutions.
-8 + 8|k/10| = -8
Add 8 to both sides.
8|k/10| = 0
Divide both sides by 8.
|k/10| = 0
Now set k/10 equal to 0 and -0.
Since -0 is the same as 0, in this case you will only get one equation from the absolute value part.
k/10 = 0
Multiply both sides by 10.
k = 0

Let the numbers be : a and b
The sum of the numbers equals 18 :
a + b = 18 - - - (1)The difference of the numbers equal 4 :
a - b = 4 - - - (2)From (1):
a = 18 - b - - - (3)Substitute the value of a in (3) into (2)
18 - b - b = 4
Collect like terms
18 - 2b = 4
-2b = 4 - 18
-2b = - 14
b = 14 / 2

A linear equation has more than one y intercept.what can you conclude about the graph of the equation?
Answers
The y-intercept is where a graph intersects the y axis.
Let 2 points lie on the y axis. Those are the y-intercepts.
2 lines can only have 0 intersections, 1 intersection, or infinitely many intersections.
Thus, if a line intersects another line more than 2 times, both lines must be the same line.
Using that information to create a line, you would have the line x=0.
x=0 is a vertical line that intersects the y-axis infinitely many times since they are the same line.
However, x=0 is not a function.

Ten years from now Sam will be twice as old as she was three years ago.How old is she now?
Answers
Answer:
is ther any information about how old he will be in ten years from now
Step-by-step explanation:
g\
Sam's current age is 16 years old based on the provided condition.
Ten years from now, Sam will be twice as old as she was three years ago. Let's represent Sam's current age as x. According to the given condition:
Age after ten years = x + 10
Age three years ago = x - 3
Given that the age after ten years will be twice the age three years ago:
x + 10 = 2(x - 3)
Solving for x:
x + 10 = 2x - 6
x = 16
Therefore, Sam is currently 16 years old.

Which statement and explanation about the product of a 3-digit number and a 2-digit number is correct?
A. The product always has 4 digits. The least 3-digit number is 100, and the least 2-digit number is 10. The product of 100 and 10 has 4 digits, so any product of a 3-digit and a 2-digit number must have 4 digits.
B. The greatest number of digits in the product is 6. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 3 digits and 2 digits equals 6 digits, so no product of a 3-digit and a 2-digit number can have more digits.
C. The product always has 5 digits. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 999 and 99 has 5 digits, so any product of a 3-digit and a 2-digit number must have 5 digits.
D. The greatest number of digits in the product is 5. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 999 and 99 has 5 digits, so no product of a 3-digit and a 2-digit number can have more digits.

The correct statement is :
D. The greatest number of digits in the product is 5. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 999 and 99 has 5 digits, so no product of a 3-digit and a 2-digit number can have more digits.
The smallest 2 digits is 10, and the smallest 3 digits is 100
Their product is:
[tex]10 \times 100 = 1000[/tex] i.e. 4 digits
The greatest 2 digits is 99, and the greatest 3 digits is 999
Their product is:

This means that;
No product of the digits can have more than 5 digits
And, no product can have less than 4 digits

Right now Seth's age is 4/5 the age of his brother Eric. Twenty-one years ago, Eric was twice as old as Seth. What are their ages now?
Answers
Final answer:
To find Seth and Eric's current ages, we can set up two equations using the given information and solve them simultaneously.
Explanation:
To solve this problem, let's start by assigning variables to the ages of Seth and Eric. Let Seth's age be represented by 'S' and Eric's age be represented by 'E'. We are given that currently Seth's age is 4/5 the age of Eric:
S = (4/5)E
We are also given that twenty-one years ago Eric was twice as old as Seth:
E - 21 = 2(S - 21)
Now we can solve these equations simultaneously to find their current ages. Let's substitute the value of S from the first equation into the second equation:
E - 21 = 2((4/5)E - 21)
Simplifying the equation, we get:
E - 21 = (8/5)E - 42
Moving all the terms with 'E' to one side, we get:
(8/5)E - E = 42 - 21
Simplifying further, we get:
(3/5)E = 21
To solve for E, we can multiply both sides of the equation by 5/3:
E = (5/3) * 21 = 35
Now that we know Eric's age, we can substitute this value back into the first equation to find Seth's age:
S = (4/5) * 35 = 28
Therefore, Eric is currently 35 years old and Seth is currently 28 years old.
