-9 x -5 = 45

45 x - 6 = -270

-270 x -3 = 810

The answer is positive because a negative multiplied by a negative equals a positive number.

-9 x -5 = 45

45 x 6 = 270

270 x -3 = -810

This answer is negative because a negative multiplied by a positive  equals a negative number.

Answer:

58.3m^3

Step-by-step explanation:

volume of a pyramid = 1/3 x length x width x height

1/3 x (6.1 x 6.1 x 4.7) = 58.3 m^3

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

The second line is 153ft long.

We are making a figure out of the given statment. Where we have the Triangle ABC and other two Triangle ADB and ADC inside Triangle ABC. Here Angle ADC = 80 degress and Angle ACD = 40 egress.

According to given statement and figure,

In triangle ABO, AD= 100 ft

Hence, BD/AD = Cos80

or, BD = (100 * Cos80)

or, BD = 17.36 ft

Now, AB/AD = Sin80

or, AB = (100* Sin 80)

or, AB = 98.48

Now, In case of triangle ABC

AB/AC = Sin40

or, AC = AB/ Sin 40

or, AC = 98.48/ Sin40

or, AC = 153.2 ft (nearly equal to 153 ft)

The second line is 153ft long.

Answer:

Statement c:

a₁₁ + ( b₁₁+ c₁₁ ) = 0

Step-by-step explanation:

The options are:

a: a₁₁ = 0 and b₁₁ = 0

b: a₁₁ - ( b₁₁ + c₁₁ ) = 0

c. a₁₁ + ( b₁₁+ c₁₁ ) = 0

d. a₁₁x( b₁₁ + c₁₁) = 0

We know that A, B, and C are matrices of the same size, so we can write:

[tex]A = \left[\begin{array}{ccc}a_{11}&a_{21}&...\\a_{21}&a_{22}&...\\...&...&...\end{array}\right][/tex]

[tex]B = \left[\begin{array}{ccc}b_{11}&b_{21}&...\\b_{21}&b_{22}&...\\...&...&...\end{array}\right][/tex]

[tex]C = \left[\begin{array}{ccc}c_{11}&c_{21}&...\\c_{21}&c_{22}&...\\...&...&...\end{array}\right][/tex]

And here we have the sum of matrices, remember that:

[tex]A + B = \left[\begin{array}{ccc}a_{11}&a_{21}&...\\a_{21}&a_{22}&...\\...&...&...\end{array}\right] + \left[\begin{array}{ccc}b_{11}&b_{21}&...\\b_{21}&b_{22}&...\\...&...&...\end{array}\right] = \left[\begin{array}{ccc}a_{11} + b_{11}&a_{21} + b_{12}&...\\a_{21} + b_{21}&a_{22} + a_{22}&...\\...&...&...\end{array}\right][/tex]

And we know that (A + B) + C = 0 (a matrix full of zeros)

then:

[tex]\left[\begin{array}{ccc}(a_{11} + b_{11}) + c_{11} &(a_{21} + b_{12}) + c_{12}&...\\(a_{21} + b_{21}) + c_{21}&(a_{22} + b_{22}) + c_{22}&...\\...&...&...\end{array}\right] = \left[\begin{array}{ccc}0&0&...\\0&...&...\\...&...&...\end{array}\right][/tex]

Then:

(a₁₁ +  b₁₁ )+ c₁₁ = 0

These are real numbers, so we can rewrite this as:

a₁₁ + ( b₁₁+ c₁₁ )  = 0

Then statement c is the correct one.

Step-by-step explanation:

The average time is 7.5.  The average is calculated by dividing the total number of values in a given set by the sum of all the values in that set.

An average is a single number chosen to represent a group of numbers; it is often the sum of the numbers divided by the number of numbers in the group. Average The arithmetic mean is calculated by adding a set of numbers, dividing by their count, and then taking the result.

If every number in a list is the same number, then that number also serves as the average for the list. Every one of the diverse varieties of average shares this characteristic.

An average of the values in a sample of data can be used to define a mean. In other words, the arithmetic mean is another name for an average. A mean is a term used to describe the average.

Average = Sum /  Count

Sum = 7.48 + 7.45 + 7.90 + 7.37 + 7.25 + 7.40 + 7.55 + 7.60

= 60 / 8

= 7.5

The fish is closer to sea level. Sea level is defined as the mean sea level, which is a fixed point of reference for measuring altitude.

The altitude of the fish is -20.2 meters, which is closer to sea level than the altitude of the bird at 38.1 meters. This means that the fish is closer to sea level than the bird.  To explain further, sea level altitude is a point of reference that is used to measure the altitude of other objects. Sea level altitude is defined as the mean sea level which is a fixed point.

Therefore, when trying to determine which animal is closer to sea level, it is important to look at the altitude of both the fish and the bird. The altitude of the fish is -20.2 meters, which is closer to sea level than the altitude of the bird at 38.1 meters. This means that the fish is closer to sea level than the bird.

Retail price of the product will be double its mean will have a prbability of 0.0401.

An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the center of the range.

A probability distribution that is symmetric around the mean is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean. The normal distribution appears as a "bell curve" on a graph.

The value of the product considering = $37*2 = $74(x)

Mean = $37

Standard Deviation (SD)= $20

here z= [tex]\frac{x - mean}{SD}[/tex] = [tex]\frac{74 - 37}{20} = \frac{37}{20} = 1.75[/tex]

The formula for finding the height of an isosceles triangle is h = (2*A)/b, where h is the height, A is the area of the triangle, and b is the base of the triangle. To use this formula, the area of the triangle must first be calculated. To do this, multiply the base of the triangle by its altitude, or the perpendicular distance from the base to the vertex opposite it. Once the area is known, the height of the triangle can be calculated by multiplying the area by two and dividing it by the base. This will give the height of the triangle. For example, if a triangle has a base of 5 and an area of 10, then the height of the triangle is (2*10)/5, or 4.

The Pythagorean Theorem states that [tex]a^2+b^2=c^2[/tex]. If we plug the side lengths in for a and b, we get [tex]4^2 + 6^2 = c^2[/tex].

Ratio between students(s) to female(f) adults is 7:6

while ratio between female(f) to male(m) is 4:1

So, we can write

[tex]\Rightarrow \dfrac{s}{f}=\dfrac{7}{6}\quad \ldots(i)[/tex]

Also, we can write

[tex]\Rightarrow \dfrac{f}{m}=\dfrac{4}{1}\quad \ldots(ii)[/tex]

Multiply both equations

[tex]\Rightarrow \dfrac{s}{f}\times \dfrac{f}{m}=\dfrac{7}{6}\times \dfrac{4}{1}\\\\ \Rightarrow \dfrac{s}{m}=\dfrac{14}{3}[/tex]

So, the ratio of the students to male adults is 14:3 .

She can knit total 8 pairs of identical mittens with a ball of yarn twelve inches in diameter

In the given question, Mrs. Read can knit one pair of children's mittens with a ball of yarn six inches in diameter.

We have to find how many pairs of identical mittens she can knit with a ball of yarn twelve inches in diameter.

The radius of a ball of yarn six inches in diameter is

r = 6/2 = 3 inches

The radius of a ball of yarn twelve inches in diameter is

r = 12/2 = 6 inches

Now, the volume of the six inches yarn = [tex]\frac{4}{3} \pi r^3[/tex]

The volume of the six inches yarn = [tex]\frac{4}{3} \pi (3)^3[/tex]

The volume of the six inches yarn = 36π

Now, the volume of the twelve inches yarn = [tex]\frac{4}{3} \pi r^3[/tex]

The volume of the twelve inches yarn = [tex]\frac{4}{3} \pi (6)^3[/tex]

The volume of the twelve inches yarn = 288π

Now we finding the numbers of pairs of identical mittens she can knit with a ball of yarn twelve inches in diameter

= 288π/36π

= 8

Hence, she can knit total 8 pairs of identical mittens with a ball of yarn twelve inches in diameter.
