Answer:

24

Step-by-step explanation:

thats right

The solution is d₁ = 24

The product of the elements on the main diagonal of the matrix is 24

What is multiplication of matrices?

The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix

Given data ,

Let the matrix be represented as A

Now , the value of A is

[tex]A = \left[\begin{array}{ccc}3 &2 \\ 5 &8 \\\end{array}\right][/tex]

Now , on simplifying the matrix A

The main diagonal of the matrix is having the elements ( a₁₁ ) and ( a₂₂ )

So , the product of the elements in the main diagonal is

a₁₁ = 3

a₂₂ = 8

And , the equation will be

d₁ = ( a₁₁ ) x ( a₂₂ )

Substituting the values in the equation , we get

d₁ = 3 x 8

d₁ = 24

Therefore , the value of d₁ is 24

Hence , the product of the diagonal elements of matrix is 24

Answer:

The answer is "smaller bag ".

Step-by-step explanation:

Please find the complete question in the attached file.

There are more trail mixes in the smaller pack.

It's because in the smaller bag (6.8 ounces) the trail mix is more than in the bigger bag (6.18 ounces).

It was reasonable because the capacity of the bag is not stated, and both bags will contain far more than 6,8 ounces.

Answer:

A straight angle is the same as half the circle and is 180° whereas a right angle is a quarter of a circle and is 90°. You measure the size of an angle with a protractor. Or could be shown by an arc on the figure to indicate which angles that are congruent

Answer:

D. 21, 14

Step-by-step explanation:

As the question said, a parallelogram is formed when both pairs of opposite sides are congruent. That means that 21 and 3y are equal, as are y + 7 and 2y.

21 = 3y

/3    /3

7 = y

y + 7 = 2y

-2y     -2y

-y + 7 = 0

   -  7  - 7

-y = -7

* -1  * -1

y = 7

In both instances, y = 7. Now let's substitute that.

21 = 3(7)

21 = 21 is true.

7 + 7 = 2(7)

14 = 14 is true.

With that, the lengths of the opposites sides are 21 & 14, which is D.

Answer:

B and E

Step-by-step explanation:

-14 is the answer that is used to see if they are equal or not

A is incorrect because it equals -6.

B is correct because it equals -14.

C is incorrect because it equals 6.

D is incorrect because it equals -6.

E is correct because it equals -14.

Answer:

54.9 meters

Step-by-step explanation:

Given: Avery threw football 60 yards

To find: How high it is in meters

Solution: Simply convert 60 yards to meters, by doing that, find out how many meters are in one yard

                                                   1 = 0.9144

Multiply the result by 60

                                              60 × 0.9144 =  54.86

Then, round it to the nearest tenths;  54.9                                              

Avery threw the football 54.9 meters high

Profit on each hat = $3

To find: The percent of the selling price of each hat is the profit.

Ratio of profit to selling price = [tex]\dfrac3{12}=\dfrac14[/tex]

The required percentage = Ratio of profit to selling price x 100

[tex]=\dfrac14\times100=25\%[/tex]

The profit is 25% of the selling price.

Answer:

two polygons are congruent if and only if there exists a composition of translation/rotations that maps one polygon to the other polygon.

(instead of translations/rotations we could write transformations, but there are transformations that also change the size of the figure, so I think that writing translations/rotations is more precise)

Step-by-step explanation:

Two figures are congruent if they have the same shape and size.

So for example, if we have one triangle, and we reflect that triangle along some line, those bot images will have the same shape and size (but maybe different orientations) so the triangles are still congruent.

Also, we could translate the image, or simply rotate it along some point, and the resulting image will be congruent to the initial image.

Then two polygons are congruent if and only if there exists a composition of translation/rotations that maps one polygon to the other polygon.

The composition that maps one polygon to the other polygon to make both congruent is called; Similarity transformation.

Now, we are told that there has to be a composition that will map one polygon to another one. This means that the two polygons must have the same shape after transformation.

Answer:

Step-by-step explanation:

Assuming the field is a rectangle, the perimeter is found through the equation:

[tex]P = 2l + 2w[/tex]

Since we know the perimeter and width, we can substitute and solve for the length.

[tex](220) = 2l + 2(62)\\220 = 2l + 124\\96 = 2l\\l = 48\\[/tex]

Using the length and width, we can find the area.

[tex]A = lw\\A = (48)(62)\\A = 2976[/tex]

The area is 2976 squared meters. We divide by the area a bag of canola seed can cover and round up if necessary to find the total number of bags.

[tex]n = 2976 / 185\\n = 16.09[/tex]

Because we need a whole bag in order to cover for the decimal area, we round up to 17 bags.

Answer:

 BC ≈ 17.0 (neither Crow nor Toad is correct)

Step-by-step explanation:

The left-side ratio of (2+4)/4 = 3/2 suggests BC is 3/2 times the length DE. If that were the case, BC = (3/2)(11) = 16.5, as Crow says.

The right-side ratio of (5+9)/9 = 14/9 suggests that BC 9 is 14/9 times the length DE. If that were the case, BC = (14/9)(11) = 154/9 = 17 1/9 ≈ 17.1, as Toad says.

The different ratios of the two sides (3/2 vs 14/9) tell you that the triangles are NOT similar, so the length of BC cannot be found by referring to the ratios of the given sides.

Rather, the Law of Cosines must be invoked, first to find angle A (109.471°), then to use that angle to compute the length of BC given the side lengths AB and AC. That computation gives BC ≈ 16.971. (See the second attachment.)

Answer:

18.76%

Step-by-step explanation:

effective interest rate = ( 1 + periodic interest rate)^m - 1

m = number of compounding = 365

Periodic interest rate = APR / number of compounding = 17.2 / 365 = 0.0471% = 0.000471

(1 + 0.000471) ^365 - 1 = 18.76%

Answer:

76 ice cream cones

Step-by-step explanation:

Given the model : y=1.8x−76.9 ;

Which shows the relationship between temperature and number of ice cream cones sold ;

Using the model, the predicted number of ice cream cones sold when temperature is 85°F

Hence, x = 85

Putting x = 85 in the model and solve for y

y = 1.8(85) −76.9

y = 153 - 76.9

y = 76.1

Hence, the number of ice cream cones sold is 76
