Answer:

Exercise 1: The length of the unknown leg is 4 inches.

Exercise 3: The following straws can be used to construct the triangle: b) [tex]3\,in[/tex], c) [tex]4.5\,in[/tex], d) [tex]6.5\,in[/tex], e) [tex]10\,in[/tex], f) [tex]13.5\,in[/tex]

Exercise 4: Possible options of this exercise: 1) (2, 4, 5), 2) (4, 5, 6), 3) (5, 6, 10), 4) (1, 2, 11), 5) (1, 4, 11), 6) (1, 10, 11)

Step-by-step explanation:

Exercise 1:

Let suppose that triangle represented in the figure is a right triangle, the length of the missing leg is determined by Pythagorean Theorem:

[tex]y = \sqrt{l^{2}-x^{2}}[/tex] (1)

Where:

[tex]l[/tex] - Hypotenuse, in inches.

[tex]x[/tex] - Known leg, in inches.

[tex]y[/tex] - Unknown leg, in inches.

If we know that [tex]l = 11\,in[/tex] and [tex]x = 10\,in[/tex], then the length of the unknown leg is:

[tex]y = \sqrt{21}[/tex]

Since 4 is the least whole number closest to [tex]\sqrt{21}[/tex], then we conclude that the length of the unknown leg is 4 inches.

Exercise 3:

The range of possible lengths for the missing side of the triangle is represented by the following simultaneous inequality:

[tex]x + y > l > x-y[/tex] (2)

Where:

[tex]x[/tex] - Greater side, in inches.

[tex]y[/tex] - Lesser side, in inches.

[tex]l[/tex] - Missing side, in inches.

If we know that [tex]x = 8\,in[/tex] and [tex]y = 6\,in[/tex], then we have the following range of missing sides:

[tex]14\,in > l > 2\,in[/tex]

The following straws can be used to construct the triangle: b) [tex]3\,in[/tex], c) [tex]4.5\,in[/tex], d) [tex]6.5\,in[/tex], e) [tex]10\,in[/tex], f) [tex]13.5\,in[/tex]

Exercise 4:

Let check each pair to determine possible constructions by means of the inequality used in Exercise 3:

(i) [tex]x = 4\,in, y = 2\,in[/tex]

[tex]6\,in>l>2\,in[/tex]

Possible choices: 5 inches.

(ii) [tex]x = 5\,in, y = 2\,in[/tex]

[tex]7\,in > l > 3\,in[/tex]

Possible choices: 4 inches, 6 inches.

(iii) [tex]x = 6\,in, y = 2\,in[/tex]

[tex]8\,in > l > 4\,in[/tex]

Possible choices: 5 inches, 6 inches.

(iv) [tex]x = 10\,in, y = 2\,in[/tex]

[tex]12\,in > l > 8\,in[/tex]

Possible choices: None.

(v) [tex]x = 5\,in, y = 4\,in[/tex]

[tex]9\,in > l > 1\,in[/tex]

Possible choices: 2 inches, 6 inches.

(vi) [tex]x = 6\,in, y = 4\,in[/tex]

[tex]10\,in > l > 2\,in[/tex]

Possible choices: 5 inches.

(vii) [tex]x = 10\,in, y = 4\,in[/tex]

[tex]14\,in > l > 6\,in[/tex]

Possible choices: None.

(viii) [tex]x = 6\,in, y = 5\,in[/tex]

[tex]11\,in > l > 1\,in[/tex]

Possible choices: 2 inches, 4 inches, 10 inches.

(ix) [tex]x = 10\,in, y = 5\,in[/tex]

[tex]15\,in > l > 5\,in[/tex]

Possible choices: 6 inches.

(x) [tex]x = 10\,in, y = 6\,in[/tex]

[tex]16\,in > l > 4\,in[/tex]

Possible choices: 5 inches.

Possible options of this exercise: 1) (2, 4, 5), 2) (4, 5, 6), 3) (5, 6, 10), 4) (1, 2, 11), 5) (1, 4, 11), 6) (1, 10, 11)

Answer: Give other user brainliest

Step-by-step explanation:

Answer:

The sides of an angle are the rays of the angle. So,

1)The sides of ∠YVW are the 2 rays of the angle VY and VW

2)The sides of ∠XVY are the 2 rays of the angle VX and VY

Angles adjacent to an angle are the angles next to the main angle

3)The angle adjacent to ∠ZVW is ∠YVZ and ∠WVX

4)The angle adjacent to ∠XVZ is ∠ZVW and ∠XYW

5)The angle adjacent to ∠YVZ is ∠ZVW and ∠YVX

The side common to the angles is the common ray of both angles

6)The side common to ∠XVY and ∠YVZ is ray VY

7)The side common to ∠XVZ and ∠ZVW is ray VZ

8)The side common to ∠XVZ and ∠ZVY is ray VZ

9)The side common to ∠XVY and ∠YVW is ray VY

The common vertex is the point where all rays converg,

10)The common vertex is V

Answer: 14 5/14 bags of woods

Step-by-step explanation:

Since one bag of wood chips covers a 3 1/2 yard section of the trail and the section of the trail is 50 1/4 yards long, the number of bags of wood chips that are needed to cover the wet section of the trail will be calculated by dividing the wet section of the trail by 3 1/2. This will be:

= 50 1/4 ÷ 3 1/2

= 201/4 ÷ 7/2

= 201/4 × 2/7

= 402/28

= 201/14

= 14 5/14 bags of woods

The fraction is 29/50, so the percent would be:

29 divided by 50 = 0.58, so as a percent that would be 58%

Answer:

the answerrrr I believe is C

Answer: Reduction, 1/5

Because the image is smaller than the pre-image, it would be a reduction. Then you would count the length of one side of the Images. The length of the pre-image is 20 and the new image is 4. Then you would make a ratio of the new image to the pre-image which is 4/20, which simplifies to 1/5.

The scale factor of the dilation will be 1/4.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The blue figure is a dilation image of the black figure.

And, The origin is the center of dilation.

Now,

Since, The blue figure is a dilation image of the black figure.

And, The origin is the center of dilation.

Here, The length of black figure = 16 units

And, The length of blue figure = 4 units

So, The scale factor of the dilation = 4/16

                                                      = 1/4

Answer:

994.88 in2

Step-by-step explanation:

Use the surface area formula SA = 4(pi)(r2) which results in SA = 4(3.14)((8.9)2) = 994.88 square inches. Because the bowl represents half a sphere, it is necessary to divide that answer by 2 to get the surface of the bowl.

If radius of a salad bowl is 8.9 inches then the surface area of the bowl is 497.44 square inches, option c is correct.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that  radius of a salad bowl is 8.9 inches.

We have to find the  surface area of the bowl

The surface area of a half-sphere is given by the formula:

SA = 2πr²

where r is the radius of the sphere.

In this case, the radius of the salad bowl is 8.9 inches.

Substituting this value into the formula, we get:

SA = 2 x 3.14 x (8.9)²

SA = 497.44 square inches

Surface area =497.44 square inches

Hence, if radius of a salad bowl is 8.9 inches then the surface area of the bowl is 497.44 square inches, option c is correct.
