how many times the size 0.81 is 810

Answer:

204000 < x < 254000

Step-by-step explanation:

700000 < 496000 + x < 750000

Solve for x by subtracting 496000 from both sides

204000 < x < 254000 ----> so we can conclude that she can spend between $204,000 and $254,000 more and remain within her estimate.

Using the circumference formula we know that the wheel of a diameter 12 in will cover 6.26 ft.

The circumference of a circle or ellipse in geometry is its perimeter.

That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.

The curve length around any closed figure is more often referred to as the perimeter.

Now, we know that the radius is 12/2 = 6 in.

Then circumference will be:

= 2πr

= 2π6

= 37.6

= 37.6 * 2

= 75.2 in

We know that:
1 inch = 0.083 ft

75.2 inch = 6.26 ft

Therefore, using the circumference formula we know that the wheel of the diameter 12 in will cover 6.26 ft.

Answer:

Step-by-step explanation:

8x + 12y - 2z = -36

-5x + 3y + 2z = 15

3x + 15y = -21

3x + 2y - 4z = -24

-10x + 6y + 4z = 30

-7x + 8y = 6

3x + 15y = -21

-21x + 24y = 18

21x + 105y = -147

129y = -129

y = -1

4x - 6 - z = -18

4x - z = -12

3x - 2 - 4z = -24

3x - 4z = -22

4x - z = -12

3x - 4z = -22

-16x + 4z = 48

  3x - 4z = -22

-13x = 26

x = -2

-5(-2) + 3(-1) + 2z = 15

1. The statement that is NOT correct is (A) A transition matrix is always invertible.

Transition Matrix:

The matrix P is the transition matrix for a linear transformation from Rn to Rn if and only if P[x]c= [x]b

where[x]c and [x]b are the coordinate column vectors of x relative to the basis c and b, respectively.

A transition matrix is a square matrix.

Every square matrix is not always invertible.

This statement is not correct.

2. The dimension of the kernel of f is an integer value between 0 and 11.

The rank-nullity theorem states that the dimension of the null space of f plus the dimension of the column space of f is equal to the number of columns in the matrix of f.

rank + nullity = n

Thus, dim(kernel(f)) + dim(range(f)) = 11

Dim(range(f)) is at most 1 because f maps R11 to R1.

Therefore, dim(kernel(f)) = 11 - dim(range(f)) which means that the possible values for dim(kernel(f)) are all integer values between 0 and 11.

Answer:

$600

Step-by-step explanation:

The bike is $800

if the bike cost 3/4 of regular price then you multiply $800 * (3/4)

3/4 = .75

$800 * .75 = $600

Sale price is $600

Answer:

$75.6

Explanation:

If the original cost was $70 and it was marked up 20%, the price after this is calculated as:

$70 + $70(0.2) = $70 + $14 = $84

Where $70(0.2) = $14 is the amount added to the original when it is marked up 20%.

Then, it was discounted 10%, we get that the selling price is

$84 - $84(0.1) = $84 - $8.4 = $75.6

Where $84(0.1) = $8.4 is the discount made on the initial price.

Therefore, the answer is $75.6

The measures in the circle given in the image above are calculated as:

1. m<PSQ = 130°;   2. m<AQS = 30°; 3. m(QR) = 100°; 4. m(PS) = 110°; 5. (RS) = 70°.

In order to find the measures in the circle shown, recall that according to the inscribed angle theorem, the measure of intercepted arc is equal to the central angle, but is twice the measure of the inscribed angle.

1. m<PSQ = m<PAQ

Substitute:

m<PSQ = 130°

2. Find m<PBQ:

m<PBQ = 1/2(m(PQ) + m(RS)) [based on the angles of intersecting chords theorem]

Substitute:

m<PBQ = 1/2(130 + 2(35))

m<PBQ = 100°

m<AQS = 180 - [m<BAQ + m<PBQ]

Substitute:

m<AQS = 180 - [(180 - 130) + 100]

m<AQS = 30°

3. m(QR) = m<QAR

Substitute:

m(QR) = 100°

4. m(PS) = 180 - m(RS)

Substitute:

m(PS) = 180 - 2(35)

m(PS) = 110°

5. m(RS) = 2(35)

m(RS) = 70°

Answer:

64

Step-by-step explanation:

cus 8 times 4 is 32 and 32 times 2 is 64

The double of 8 multiplied by 4 is 64. This means that if we multiply 8 by 4 and then multiply the result by 2, we obtain 64. The multiplication operation is performed first (8 * 4 = 32), and then the result is doubled by multiplying it by 2 (2 * 32 = 64).

To find the double of 8 multiplied by 4, we can perform the following calculation:

Double of 8x4 = 2 * (8 * 4)

First, we multiply 8 and 4:

8 * 4 = 32

Next, we multiply the result by 2:

2 * 32 = 64

Therefore, the double of 8 multiplied by 4 is 64. This means that if we multiply 8 by 4 and then multiply the result by 2, we obtain 64. The multiplication operation is performed first (8 * 4 = 32), and then the result is doubled by multiplying it by 2 (2 * 32 = 64).

No, the F-test statistic cannot be less than 1 when it represents the larger of two sample variances.

The F-distribution is always a positive distribution with a range of values greater than zero. The F-test value is always greater than or equal to 0, but it is not always less than or equal to 1.

The numerator, representing the bigger sample variance, is always greater than or equal to the denominator, representing the smaller sample variance. Consequently, the F-ratio, which is the ratio of the larger to the smaller variance, is always greater than or equal to 1. Thus, an F-test statistic that is less than 1 is mathematically incorrect.

Therefore, an F-test statistic is always a positive number that is greater than or equal to zero and greater than or equal to 1. This is because the numerator of an F-distribution is always greater than or equal to the denominator.

According to the Question, The interest earned in 4 years is $1,954.83.

What is compounded quarterly?

A quarterly compounded rate indicates that the principal amount is compounded four times over one year. According to the compounding process, if the compounding time is longer than a year, the investors would receive larger future values for their investment.

The principal is $10,000.

The annual interest rate is 4.5%, which is compounded quarterly.

Since there are four quarters in a year, the quarterly interest rate can be calculated by dividing the annual interest rate by four.

The formula for calculating the future value of a deposit with quarterly compounding is:

\(P = (1 + \frac{r}{n})^{nt}\)

Where P is the principal

The annual interest rate is the number of times the interest is compounded in a year (4 in this case)

t is the number of years

The interest earned equals the future value less the principle.

Therefore, the interest earned can be calculated as follows: I = FV - P

where I = the interest earned and FV is the future value.

Substituting the given values,

\(P = $10,000r = 4.5/4 = 1.125n = 4t = 4 years\)

The future value is:

\(FV = $10,000(1 + 1.125/100)^{4 *4} = $11,954.83\)

Therefore, the interest earned is:

\(I = $11,954.83 - $10,000= $1,954.83\)

Thus, the interest earned in 4 years is $1,954.83.

when students = x:

SC = 3x + 125

DD = 8x

equation:

3x + 125 < 8x

subtract 3x from both side:

3x + 125 - 3x < 8x - 3x

The ratios of their perimeters and the ratios of their areas are 1) 3:1 and 9:1 and 2) 7:4 and 49:16.

Given the scale factor of two similar polygons, we need to find the ratio of their perimeters and the ratios of their areas,

To find the ratio of the perimeters of two similar polygons, we can simply write the scale factor as it is because the ratio of the perimeter is equal to the ration of the corresponding lengths.

1) So, perimeter = 3:1

The ratio of areas between two similar polygons is equal to the square of the scale factor.

Since the scale factor is 3:1, the ratio of their areas is:

(Ratio of areas) = (Scale factor)² = 9/1 = 9:1

Similarly,

2) Perimeter = 7:4

Area = 49/16

Hence the ratios of their perimeters and the ratios of their areas are 1) 3:1 and 9:1 and 2) 7:4 and 49:16.

The number of degrees in the measure of the largest angle is 315°

given that

In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon.

The name nonagon is a prefix hybrid formation, from Latin (nonus, "ninth" + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century. The name enneagon comes from Greek enneagonon (εννεα, "nine" + γωνον (from γωνία = "corner")), and is arguably more correct,though less common than "nonagon".

Although a regular nonagon is not constructible with compass and straightedge (as 9 = 32, which is not a product of distinct Fermat primes), there are very old methods of construction that produce very close approximations.

It can be also constructed using neusis, or by allowing the use of an angle trisector.

the angles of a 9-gon are in ratio 3:1:4:1:5:9:2:6:5

the sum of interior angles of an 9-gon = (9-2)* 180

                                                               = 7*180

                                                               =1260°

now, we need to find the largest angle

9/(3+1+4+1+5+9+2+6+5) *1260
