The perimeter of the spiral notebook is 14 inches

Step-by-step explanation:

The given parameters are;

The area of the rectangular binder cover, Aₓ = 80 in²

The area of the rectangular binder cover = 8 × The area of the spiral notebook, Aₙ

The length, l of the spiral notebook = 5 inches

Let w represent the width of the spiral notebook cover;

We have;

Aₙ = l × w = 5 × w

Aₓ = 80 = 8 × Aₙ

8 × Aₙ = 80

∴ 8 × 5 × w = 80

w = 80/(8 × 5) = 80/40 = 2

w - 2 inches

The perimeter, P, of a rectangle = 2 × length, l + 2 × width, w

∴ For the spiral notebook, we have, [tex]P_{Spiral \ notebook}[/tex]  = 2 × 5 + 2 × 2 = 14

The perimeter of the spiral notebook, [tex]P_{Spiral \ notebook}[/tex] = 14 inches.

Answer:

2³×3²

Step-by-step explanation;

Prime Numbers are numbers which which have only two factors the number itself and one

Examples of Prime Numbers are;

2,3,5,7,11,13,17,19,23,29,etc

To Find The Prime Factorization Of The Number 72 you'll need to follow this;

72=2×36(we have the number 36 because when it's multiplied by 2 the product is 72 and 36 is not a prime number so it has to be broken down but since 2 is a prime number you leave it as it is)

72=2×2×18(we have 2×18 because because it's give us the product of 36 when multiplied so now that we have a second prime number(2) we will have to continue to break down the number 18)

72=2×2×2×9( We again have two another 2 and 9 here because when multiplied by each other its product is 18 so as we can see 9 is not a prime number so we have to break it down but the 2 is a prime number so we let it be)

72=2×2×2×3×3( As we can see here, 3 and 3 is a prime number so nothing happens to it so we have broken the non-prime numbers down so now we have all the numbers as Prime Numbers)

So; 72=2×2×2×3×3

So we are going to count the twos and threes so as you can see we have three twos and we have two threes. Which makes our final answer;

2³×3²

So The Prime Factorization of 72 is; 2³×3²

Answer:

y=-2/3x - 2/3

Step-by-step explanation:

1. ABCD is shifted some units down, and then some othe units left.

2. The figure is just moved, not reflected, not diluted. So the distances are preserved

3. ABCD is translated to OLMN mean that AB has been translated to OL, so length of LO=OL=AB= 6 units

The length of LO is as the length of AB which is 6 units.

Any closed figure made by 4 line segments joined end to end in series is called a quadrilateral.

According to the given information, the quadrilateral ABCD is translated down and left to form the quadrilateral OLMN.

As the quadrilateral is just shifted first down and then left but not changed in the dimensions thus, the dimensions of the new quadrilateral OLMN will also be the same as ABCD.

length of LO=OL=AB= 6 units

Hence, the length of LO is as the length of AB which is 6 units.

Answer:

Correct option is "Both boys are correct".

Step-by-step explanation:

The equation is:

6x - 2 = -4x + 2

        6x - 2 + 4x = -4x + 2 + 4x

        10x - 2 = 2

        10x = 4

         x = 0.40

        6x - 2 - 6x = -4x + 2 - 6x

        - 2 = -10x + 2

        10x = 4

         x = 0.40

Correct option is "Both boys are correct".

Step-by-step explanation:

Answer:

The correct option is;

a- 45° only

Step-by-step explanation:

The given equation can be presented as follows;

[tex]\dfrac{cos (2 \cdot x)}{cosine (x) + sin (x)} = 0[/tex]

We have that cos(2·x) = cos²(x) - sin²(x)

Also, we have, by the difference of two squares, the following relation;

cos²(x) - sin²(x) = (cos(x) - sin(x))(cos(x) + sin(x))

Therefore, the given equation can be written as follows;

[tex]\dfrac{cos (2 \cdot x)}{cosine (x) + sin (x)} = \dfrac{(cos(x) - sin(x)) \times (cos(x) + sin(x))}{(cos (x) + sin (x))} =0[/tex]

Crossing the common term, (cos(x) + sin(x)), in the numerator and the denominator, we have;

[tex]\dfrac{(cos(x) - sin(x)) \times (cos(x) + sin(x))}{(cos (x) + sin (x))} = cos(x) - sin(x) = 0[/tex]

From cos(x) - sin(x) = 0, we have;

Adding sin(x) to both sides of the equation

cos(x) - sin(x) + sin(x) = 0 + sin(x)

cos(x) = sin(x)

Therefore, the opposite leg and the adjacent leg of the right triangle formed with reference to the angle x are equal

∴ x = 90/2 = 45° only for 0° ≤ x ≤ 180°

A. 45 only

Carl wheezer told me

The interest on a note of $32,000 at 9% for three months is $720.

It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.

It is given that,

Principal(P) = $32,000

Rate(R) = 9%

Time(T) = 3/12 = 0.25 years

Interest(I)=?

Automobile loans that are amortized monthly and retailer installment loans that are also calculated monthly are examples of simple interest; the interest increases as the loan balance decreases with each monthly payment. Using simple interest, certificates of deposit (CDs) pay a predetermined amount of interest on a predetermined date.

The formula for the simple interest is,

I=(P×R×T)/100

Substitute the given value as

I=(P×R×T)/100

I=(32,000×9×0.25)/100

I=$720

Thus, the interest on a note of $32,000 at 9% for three months is $720.

  B (correctly marked)

  1/3, 1/2, 4

Step-by-step explanation:

The rational root theorem tells you the rational roots will be of the form:

  ±(divisor of constant)/(divisor of leading coefficient)

Here, that means they will be of the form ±{1, 2, 4}/{1, 2, 3, 6}.

Right away, you can eliminate choices A and C because there cannot be 9 in the numerator, and the number of possibilities goes beyond just 1, 2, and 4.

Possible rational roots are ...

  ±1, ±2, ±4, ±1/2, ±1/3, ±1/6, ±2/3, ±4/3

I like a graphing calculator for finding the roots of higher-degree polynomials. A graph of this one shows roots to be 1/3, 1/2, and 4.

_____

Descartes' rule of signs tells you there are 0 negative real roots, and 1 or 3 positive real roots. The ratio of the first two coefficients suggests that one of the roots may be relatively large, so it might work to try 4.

  ((6·4 -29)·4 +21)·4 -4 = (-20 +21)·4 -4 = 0

So, x=4 is a root. Synthetic division (2nd attachment) shows the remaining quadratic factor to be 6x^2 -5x +1. Factoring this*, we have ...

  6x^3 -29x^2 +21x -4 = (x -4)(6x^2 -5x +1) = (x -4)(3x -1)(2x -1)

The roots associated with the quadratic factor are 1/3 and 1/2.

The real roots are 1/3, 1/2, and 4.

* To factor ax^2 +bx +c, you look for factors of the product ac that have a sum of b. Here, you're looking for factors of 6·1 = 6 that have a sum of -5.

  6 = (-1)(-6) = (-2)(-3) . . . sums are -7 and -5

The numbers we're looking for are -2 and -3. Then the factorization is (6x -2)(6x-3)/6 = (3x -1)(2x -1).

Note that we have identified 'p' and 'q' as the factors of 'ac' that total to 'b'. The factorization is then (ax+p)(ax+q)/a. Here, both factors end up with coefficients of x that are not unity. That is not always the case.

There are other ways to make use of 'p' and 'q'. You can also rewrite the quadratic as ax^2 +px +qx +c, and factor by grouping.

y - 0 = 1.2(x - 5)

y = 1.2x - 6

The equation of the line is:

[tex]y = 1.2x - 6[/tex]

--------------------

The equation of a line, in slope-intercept formula, is given by:

[tex]y = mx + b[/tex]

In which:

[tex]y = 1.2x + b[/tex]

It passes through point (5,0), which means that when [tex]x = 5, y = 0[/tex], and this is used to find b.

[tex]y = 1.2x + b[/tex]

[tex]0 = 1.2(5) + b[/tex]

Answer:

C. x = 8

Step-by-step explanation:

We know that x · x · x is equal to 512. We know it cannot be negative because then the 512 would be negative. -2 x -2 x -2 is -8. -2 x -2 is 4. We know it cannot be B x = -6 or D. x = -8.

Let's multiply 6 x 6 x 6.

                           36 x 6 = 216.

Let's multiply 8 x 8 x 8.

                          64 x 8 = 512
