The number 3.249 rounded to nearest tenth is; 3.2

According to the question;

According to the place value concept in mathematics; the place values after the decimal point in a decimal number are identified from left to right, as tenths, hundredths, thousandths etc.

Evidently, the number which occupies the tenths position in 3.249 is the digit 2.

Since, 4 is less than 5, it is rounded off to 0 and added to the digit, 2 which occupies the tenths position in the number 3.249

Ultimately, the number 3.249 rounded to nearest tenth is 3.2.

Answer:

3,600

Step-by-step explanation:

First you have to know that 12% is the same as .12 Since you have 12%interest you would multiply 30,000 × .12 When you do you get 3,600. This is your interest. You could also do it another way. You could take 30,000 and divide it by the 6 months. You get 5,000. Now you would take this number and multiply it by .12(the 12%) and get 600. This is interest per month. Since you have 6 months you multiply 600×6. You end up with 3,600.

The two unknown numbers 'a' and 'b' are 34 and 27.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let the two numbers be 'a' and 'b'.

Given, The sum of two numbers is 61 which is (a + b) = 61...(i)

Also given the difference is 7 which is (a - b) = 7...(ii)

Adding the equations (i) and (ii) we get,

2a = 68          (+ b and - b cancel out)

a = 34 and hence 34 + b = 61 ⇒ b = 27.

Gabriella got the better deal, as she paid slightly less per pound for the tomatoes.

To determine who got the better deal, we need to calculate the price per pound of tomatoes for each person.

For Clay:

Price per pound = Total price / Total pounds

Price per pound = $13.50 / 214 pounds ≈ $0.0631 per pound

For Gabriella:

Price per pound = Total price / Total pounds

Price per pound = $6.75 / 112 pounds ≈ $0.0607 per pound

Comparing the two, we see that Gabriella paid approximately $0.0607 per pound, while Clay paid approximately $0.0631 per pound.

The value of i^{20}+1 is 2, which is calculated by recognizing that the powers of i repeat every 4 cycles and that i^20 simplifies to 1.

The value of i^{20}+1 can be determined by understanding the properties of the imaginary unit i, which is defined by i^2 = -1.

The powers of i follow a cyclical pattern: i^0 = 1, i^1 = i, i^2 = -1, i^3 = -i, and i^4 = 1, with this pattern repeating every 4 powers.

To find i^{20}, we observe that 20 is divisible by 4 (20 = 4 × 5), so i^{20} = (i^4)^5 = 1^5 = 1.

Add 1 to this result, and we get i^{20} + 1 = 1 + 1 = 2.

Answer:

Yes

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 270°

a point (x, y ) → (y, - x )

Thus

A(1, 1 ) → A'(1, - 1 )

B(1, 4 ) → B'(4, - 1 )

C(3, 4 ) → C'(4, - 3 )

D(6, 1 ) → D'(1, - 6 )

These are the correct coordinates for the diagram A'B'C'D'

A translation (x, y ) → (x + 4, y + 1 )

Add 4 to the x- coordinates and add 1 to the y- coordinates, that is

A'(1, - 1 ) → A''(1 + 4, - 1 + 1 ) → A''(5, 0 )

B'(4, - 1 ) → B''(4 + 4, - 1 + 1 ) → B''(8, 0 )

C'(4, - 3 ) → C''(4 + 4, - 3 + 1 ) → C''(8, - 2 )

D'(1, - 6 ) → D''(1 + 4, - 6 + 1 ) → D''(5, - 5 )

These are the correct coordinates for the diagram A''B''C''D''

Hence the composition of transformations is correct

Final answer:

The absolute value equation that has solutions of 3 and -3 is |x| = 3. Substituting x = 3 or x = -3 into the equation both result in true statements, confirming they are the correct solutions.

Explanation:

The student is asking about solving an absolute value equation that has solutions of 3 and -3. To tackle this problem, you want to set up an equation where the absolute value is equal to both positive and negative 3. The most straightforward equation that satisfies this condition is |x| = 3. This equation means that the solution, x, can be either 3 or -3 because the absolute value of both numbers is 3. To verify that these are the correct solutions, you can substitute them back into the original equation:

For x = 3: |3| = 3, which simplifies to 3 = 3, confirming the solution.

For x = -3: |-3| = 3, which simplifies to 3 = 3, again confirming the solution.

This absolute value equation is an identity because substituting either solution results in a true statement.
