x=30º

∠CAB=60°

∠ACB=80°

Step-by-step explanation:

Because the angles of every triangle add up to 180º, we know that:

[tex]2x+20+2x=180-40\\ 4x=180-40-20\\ 4x=180-60\\ 4x=120\\ x=\frac{120}{4}[/tex]

x=30º

Plug that in for x on both angles, and you will get

∠CAB=60°

∠ACB=80°

A person is designing a new rectangular garden. Its area must be 344 square feet. List the length and​ width, in​ feet, of all the possible gardens with this area. Use​ whole-number dimensions. Which garden has the least​ perimeter?

Answers

Answer:

(1 x 344) ft

(344 x 1) ft

(2 x 172) ft

(172 x 1) ft

(4 x 86) ft

(86 x 4) ft

(8 x 43) ft

(43 x 8) ft

the garden with the least perimeter is the garden with dimensions 8 x 43

Step-by-step explanation:

area of a rectangle = length x width

given the area, we can determine the dimensions of the rectangle by calculating the factors of 344. the factors are then multiplied to determine the area

factors of a number are numbers that divide the original number evenly. they are numbers that when used to divide another number, we derive only only numbers

Factors of 344 = 1, 2,2,2,43 and 344

Possible dimensions and their areas

1 x 344 = =344 ft²

2 x 172 = 344 ft²

4 x 86 = 344 ft²

8 x 43 = 344 ft²

Perimeter of a rectangle = 2 x (length + width)

i would use the dimensions i calculated to determine all the possible perimeters

2 x ( 1 + 344) = 690 ft

2 x (2 + 172) = 348 ft

2 x (4 + 86) = 180 ft

2 x (8 + 43) = 102 ft

the garden with the least perimeter is the garden with dimensions 8 x 43

Television sizes are described by the length of their diagonal measure. What would be the listed size of the TV shown? (To the nearest whole inch)

Answers

Answer:

The listed size is 32 inches

Step-by-step explanation:

Given

See attachment for television

Required

The listed size

The listed size is calculated by the diagonal of the television.

This is calculated as using Pythagoras theorem as follows:

[tex]Diagonal^2 = Length1^2 + Length2^2[/tex]

Where:

[tex]Length1 =28in[/tex]

[tex]Length2 =15.7in[/tex]

So, we have:

[tex]Diagonal^2 = 28^2 + 15.7^2[/tex]

[tex]Diagonal^2 = 784 + 246.49[/tex]

[tex]Diagonal^2 = 1030.49[/tex]

Take positive square roots of both sides

[tex]Diagonal = \sqrt{1030.49[/tex]

[tex]Diagonal = 32[/tex] --- approximated

Hence, the listed size is 32 inches

Given the isosceles trapezoid EFGH and side length JL = 93 units. If the length of KN = (3x + 1) and MN = (5x - 4), what is the length of KM?

Answers

Answer:

KM=JL=93 units

or KM=KN + MN= 8x-3

Step-by-step explanation:

The value of length of KM can be equal to either JL or obtained by adding KN = (3x + 1) and MN = (5x - 4) depending on the diagram.

An isosceles trapezoid has non parallel sides congruent.

In the isosceles trapezoid the diagonals are also equal.

There is a pair of parallel lines in an isosceles trapezoid.

In the 1st figure trapezoid JL and KM are diagonals.

If we take the JM and KL to be the parallel lines then the opposite sides can be  JK and LM

And N is the middle line or the mid segment.

In the figure 2

The value of length of KM is obtained by adding KN = (3x + 1) and MN = (5x - 4)

KM=KN + MN = (5x - 4) +(3x + 1)

KM=8x- 3

Step-by-step explanation:

A deli is offering two specials. The roast beef special gives a profit of $2.30 per sandwich, and the turkey special gives a profit of $3.10 per sandwich. The roast beef special uses two slices of bread and three slices of cheese. The turkey special uses two slices of bread and four slices of cheese. The deli has 120 slices of bread and 160 slices of cheese available for the specials. The deli wants to maximize its profit selling specials. Let x represent the number of roast beef specials and y represent the number of turkey specials. What are the constraints for the problem?

Answers

Answer:

The constraints are as follows;

1) 2·x + 2·y ≤ 120

2) 3·x + 4·y ≤ 160

3) x = 2.30

4) y = 3.10

5) P = 2.3·x + 3.10

Step-by-step explanation:

The question is a word problem, with the analysis as follows;

The profit from the roast beef special per sandwich = $2.30

The profit from the turkey special per sandwich = $3.10

The number of slices of bread in the roast beef special = Two slices

The number of slices of cheese in the roast beef special = Three slices

The number of slices of bread in the turkey special = Two slices

The number of slices of cheese in the turkey special = Four slices

The number of slices of bread the deli has  = 120 slices

The number of slices of cheese the deli has = 160 slices

Let 'x' and represent the number of roast beef special and 'y' represent the number of turkey special the deli makes, then we have the constraints as follows;

For the number of slices of bread used;

2·x + 2·y ≤ 120...(1)

For the number of slices of cheese used;

3·x + 4·y ≤ 160...(2)

x = 2.30

y = 3.10

The profit 'P' is given by the following equation

P = 2.3·x + 3.10.
