Answers

Answer:

Dilate, Reflect

Not congruent, dilations are used

Step-by-step explanation:

Dilate Figure K by a factor 3 to get the white shape.

Reflecting the resulting figure over the x-axis will give you Figure L

Step 1: Dilate by a scale factor of 3

Step 2: Reflect over the x-axis

Since dilations are used, the shapes are not congruent as they change the side lengths and area.

Tirzah wants to put a fence around her garden. She has 22 yards of fence material. Does she have enough to go all the way around the garden? Explain why or why not.

Answers

Answer:

No

Step-by-step explanation:

To calculate how much fence is needed we need to calculate the perimeter NOT area.

P = 2L+2W

P =2(6.75)+2(4 2/3)

P = 13.5 + 9 1/3

P = 22 5/6

Because she only has 22 yards she does not have enough to go all the way around.

determine all combinations of lengths that vould be usef to for a traingle 4,6,12,16 and also another lengths of 8,10,14,17

Answers

Answer:

[tex]\lbrace 6,\, 12,\, 16 \rbrace[/tex].

[tex]\lbrace 8,\, 10,\, 14 \rbrace[/tex],

[tex]\lbrace 8,\, 10,\, 17\rbrace[/tex],

[tex]\lbrace 8,\, 14,\, 17 \rbrace[/tex], and

[tex]\lbrace 10,\, 14,\, 17 \rbrace[/tex].

Step-by-step explanation:

In a triangle, the sum of the lengths of any two sides must be strictly greater than the length of the other side. In other words, if [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] (where [tex]a,\, b,\, c > 0[/tex]) denote the lengths of the three sides of a triangle, then [tex]a + b > c[/tex], [tex]a + c > b[/tex], and [tex]b + c > a[/tex].

Additionally, if [tex]a,\, b,\, c > 0[/tex], [tex]a + b > c[/tex], [tex]a + c > b[/tex], and [tex]b + c > a[/tex], then three line segments of lengths [tex]\text{$a$, $b$, and $c$}[/tex], respectively, would form a triangle.

 

Number of ways to select three numbers out of a set of four distinct numbers:

[tex]\begin{aligned} \left(\begin{matrix}4 \\ 3\end{matrix}\right) &= \frac{4!}{3! \, (4 - 3)!} \\ &= \frac{4 \times 3 \times 2 \times 1}{(3 \times 2 \times 1) \times (1)} \\ &= 4\end{aligned}[/tex].

In other words, there are four ways to select three numbers out of a set of four distinct numbers.

For [tex]\lbrace 4,\, 6,\, 12,\, 16\rbrace[/tex], the four ways to select the three numbers are:

[tex]\lbrace 4,\, 6,\, 12\rbrace[/tex],[tex]\lbrace 4,\, 6,\, 16\rbrace[/tex], [tex]\lbrace 4,\, 12,\, 16\rbrace[/tex], and[tex]\lbrace 6,\, 12,\, 16\rbrace[/tex].

Among these choices, [tex]\lbrace 6,\, 12,\, 16\rbrace[/tex] satisfies the requirements: [tex]6 + 12 > 16[/tex], [tex]16 + 6 > 12[/tex], and [tex]12 + 16 > 6[/tex]. Thus, three line segments of lengths [tex]\lbrace 6,\, 12,\, 16\rbrace\![/tex] respectively would form a triangle.

The other three combinations do not satisfy the requirements. For example, [tex]\lbrace 4,\, 6,\, 12\rbrace[/tex] does not satisfy the requirements because [tex]4 + 6 < 12[/tex]. The combination [tex]\lbrace 4,\, 12,\, 16\rbrace[/tex] does not satisfy the requirement for a slightly different reason. Indeed [tex]4 + 12 = 16[/tex]. However, the inequality in the requirement needs to be a strict inequality (i.e., strictly greater than "[tex]>[/tex]" rather than greater than or equal to "[tex]\ge[/tex]".)

Thus, [tex]\lbrace 6,\, 12,\, 16\rbrace[/tex] would be the only acceptable selection among the four.

Similarly, for [tex]\lbrace 8,\, 10,\, 14,\, 17 \rbrace[/tex], the choices are:

[tex]\lbrace 8,\, 10,\, 14 \rbrace[/tex], [tex]\lbrace 8,\, 14,\, 17 \rbrace[/tex], [tex]\lbrace 8,\, 10,\, 17 \rbrace[/tex], and[tex]\lbrace 10,\, 14,\, 17 \rbrace[/tex].

All four combinations satisfy the requirements.

the middle is a square which measures 20. to find its area, l•w, so 20•20.

to find area or a triangle, you would need the base and the height. the height is 9, and the base is 20 bc of the sides of the squares. the area for the triangle would be 90. multiple this by 4.

Answers

To make 16 bags of the snack mix, Lily needs 2 cups of raisins.

Lily needs 12 cups of pretzels to make 16 bags of the snack mix.

If Lily uses 1 cup of pecans, she will need to use 5 cups of crackers.

The recipe will make 64 bags of the snack mix if Lily uses only 1 cup of pretzels.

To adjust the ingredients for each new situation, we need to consider the ratios between the original recipe and the desired number of bags.

Given the original recipe for 8 bags of snack mix:

2 cups of pretzels

1 cup of raisins

2.5 cups of crackers

0.25 cup of cranberries

0.5 cup of pecans

To make 16 bags of the snack mix, we can scale up the ingredients proportionally.

Since we are doubling the number of bags, we need to double the amounts of each ingredient:

Lily will need 2 cups × 2 = 4 cups of pretzels for 16 bags.

Lily will need 1 cup × 2 = 2 cups of raisins for 16 bags.

Lily will need 2.5 cups × 2 = 5 cups of crackers for 16 bags.

Lily will need 0.25 cup × 2 = 0.5 cups of cranberries for 16 bags.

Lily will need 0.5 cup × 2 = 1 cup of pecans for 16 bags.

To make 16 bags of the snack mix, Lily needs 2 cups of raisins, 4 cups of pretzels, 1 cup of pecans, and 5 cups of crackers.

If Lily uses 1 cup of pecans, she will need to use 2.5 cups × 1 = 2.5 cups of crackers to maintain the original ratio between the ingredients.

Lastly, if Lily uses only 1 cup of pretzels, the recipe will make 4 bags of the snack mix.

This is because we are halving the amount of the main ingredient (pretzels), which results in halving the overall quantity of the snack mix.

To make 16 bags of the snack mix, Lily needs 2 cups of raisins, 4 cups of pretzels, 1 cup of pecans, and 5 cups of crackers.

If Lily uses 1 cup of pecans, she will need to use 2.5 cups of crackers.

The recipe will make 4 bags of the snack mix if Lily uses only 1 cup of pretzels.

el angulo A y el ángulo B son ángulos verticales. Si el ángulo A=(2x-4) y el ángulo B=(4x-30), encuentra el valor de x.

Answers

Answer:

∠B = 17°

Step-by-step explanation:

Los ángulos verticales son congruentes, por lo tanto

5x + 7 = x + 15 ( restar x de ambos lados )

4x + 7 = 15 ( resta 7 de ambos lados )

4x = 8 ( dividir ambos lados por 4 )

x = 2

Por lo tanto

∠B = 5x + 7 = (5 × 2) + 7 = 10 + 2 = 17°
