Answer:

Step-by-step explanation:

First of all, write the similarity statement for the triangles.

  ΔCDE ~ ΔCBA

Identify the line segments in each triangle that you know. Preferably, choose ones that correspond.

  CE = 27, DE = the length we want to find . . . . known segments in ΔCDE

  CA = (18+27) = 45 . . . . . corresponds to CE

  BA = 28 . . . . . . . . . . . . . corresponds to DE

__

The ratios of corresponding line segments are equal:

  DE/CE = BA/CA . . . . this is the proportion you want to set up*

  DE/27 = 28/45

Multiply by the denominator of DE/27 to eliminate that:

  DE = 27(28/45)

  DE = 16.8

_____

* I usually choose to put the unknown variable in the numerator of a proportion, so that solving it only involves multiplication by the denominator. If you put the variable in the denominator, the solution takes an extra step.

Step-by-step explanation:

Total money Charnika has = $500

The money she wants to save = $200

Amount of money she can spend = $ (500 - 200)

= $300

Amount of money withdrawn in every week = $25

The number of weeks the money can be withdrawn = $ (300÷25)

= $ 12

Answer:

f(6) = 16

Step-by-step explanation:

In the next steps we use this formula : f(n)=f(n-1)+2 

Since f(1)=6 then f(2)=f(2-1)+2 = f(1)+2 = 6+2 = 8

         f(2)=8 then f(3)=f(3-1)+2  = f(2)+2 = 8+2 = 10

         f(3)=10 then f(4)=f(4-1)+2  = f(3)+2 = 10+2 = 12

        f(4)=12 then f(5)=f(5-1)+2  = f(4)+2 = 12+2 = 14

        f(5)=14 then f(6)=f(5-1)+2  = f(4)+2 = 14+2 = 16.

Answer:

Discriminant = -24, no real roots.

Step-by-step explanation:

The discriminant is what's inside the square root in the quadratic formula.

The quadratic formula is:

[tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] and [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]

a = 1

b = 2

c = 7

The question wants the discriminate, we can just focus on the square root part.

When we plug in the parts we got, it becomes:

[tex]\sqrt{4-4(1)(7)}\\\sqrt{4-28} \\\sqrt{-24}[/tex]

Since the inside of the square root is negative, there are no real roots.

Answer:

8 of the 28 horses would be palomino horses

Step-by-step explanation:

First off, we understand that there are 10 palomino horses and 25 others, meaning there are 35 total.

The question wants to know that if 28 horses came out, how many of them would be palomino horses.

We know that the palomino horses are  [tex]\frac{10}{35}[/tex]

What we need to know is [tex]\frac{x}{28}[/tex]

to find x, we cross multiply

[tex]\frac{10}{35} = \frac{x}{28}[/tex]

10 x 28 and 35 x X

280  =  35x

Divide both sides by 35

x = 8

8 of the 28 horses would be palomino horses

b) Prob (Death non watercraft collison) = 1 - Prob (Death watercraft collision) = 1 - 0.206 = 0.794

c) Prob (Prenatal or watercraft collision death) = (68 + 81) / 392 = 0.38

Language Arts 6 B  Unit 7 Lesson 13

Students would want to include sensory language which describes in the solution part that focuses on writing about their favorite food.

Sensory Language is a word or words used to evoke mental imagery and help the reader visualize the tale or poetry. Imagery is a literary method that appeals to the reader's senses, whereas Sensory Language is a writing style and how writers utilize words to generate images for the readers.

When writing about their favorite food, a student might want to include sensory language that focuses on how the food looks, smells, tastes, feels, and sounds. This can help to paint a vivid picture for the reader and make the experience of reading about the food more immersive.

For example, if the student's favorite food is pizza, they might describe the golden, crispy crust; the savory, spicy tomato sauce; the gooey, melted cheese; the spicy sausage and bell peppers; and the satisfying crunch that it makes when they take a bite. They might also describe the way the warm, comforting aroma of the pizza fills the room as it cooks, or the way the different textures and flavors come together in each bite to create a satisfying and delicious meal. By using descriptive language that focuses on the senses, the student can help the reader to better understand and share in their love of the food.

Step-by-step explanation:

Answer:

The new vertices are [tex]O''(x,y) = (-1, 0)[/tex], [tex]N''(x,y) = (6,-4)[/tex] and [tex]M''(x,y) = (3,-1)[/tex].

Step-by-step explanation:

Previously, we have to define a vectorial equation for a reflection across the line [tex]y = 1[/tex]:

Reflection across the line y = 1:

[tex]P'(x,y) = P(x,y) -2\cdot [P(x,y) -(x_{P},1)][/tex] (1)

Where:

[tex]P(x,y)[/tex] - Original point.

[tex]x_{P}[/tex] - x-Coordinate of the original point.

[tex]P'(x,y)[/tex] - Resulting point.

Translation:

[tex]P'(x,y) = P(x,y) + (3,0)[/tex] (2)

If we know that [tex]O(x,y) = (-4,2)[/tex], [tex]N(x,y) = (3, 6)[/tex] and [tex]M(x,y) = (0,3)[/tex], then the resulting points are, respectively:

Point O'

Translation

[tex]O'(x,y) = O(x,y) + (3,0)[/tex]

[tex]O'(x,y) = (-1,2)[/tex]

Reflection

[tex]O''(x,y) = O'(x,y) -2\cdot [O'(x,y) -(x_{O'},1)][/tex]

[tex]O''(x,y) = (-1,2) -2\cdot [(-1, 2)-(-1,1)][/tex]

[tex]O''(x,y) = (-1, 0)[/tex]

Point N'

Translation

[tex]N'(x,y) = N(x,y) + (3,0)[/tex]

[tex]N'(x,y) = (6,6)[/tex]

Reflection

[tex]N''(x,y) = N'(x,y) -2\cdot [N'(x,y) -(x_{N'},1)][/tex]

[tex]N''(x,y) = (6,6) - 2\cdot [(6,6)-(6,1)][/tex]

[tex]N''(x,y) = (6,-4)[/tex]

Point M'

Translation

[tex]M'(x,y) = M(x,y) + (3,0)[/tex]

[tex]M(x,y) = (3,3)[/tex]

Reflection

[tex]M''(x,y) = M'(x,y) -2\cdot [M'(x,y) -(x_{M'},1)][/tex]

[tex]M''(x,y) = (3,3) - 2\cdot [(3,3)-(3,1)][/tex]

[tex]M''(x,y) = (3,-1)[/tex]

The new vertices are [tex]O''(x,y) = (-1, 0)[/tex], [tex]N''(x,y) = (6,-4)[/tex] and [tex]M''(x,y) = (3,-1)[/tex].

Answer:

so if you want like how many she earns in 4 years then,

just do $462.30×4

after calculation answer will come.

Answer:

Roses

Zinnias

Snapdragons

Petunias

Area of rectangle = length × width

Roses → 8 × 4 = 32 ft²

Zinnias → 12 × 8 - 8 × 4 = 64 ft²

Snapdragons → 12 × 16 - 12 × 8 = 96 ft²

Petunias → 20 × 16 - 12 × 16 = 128 ft²

By using trigonometric relations we will see that the area is:

[tex]A = h*tan(60\°)*/2 = tan(60\°)*h^2/2[/tex]

Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.

Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).

h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:

tan(60°) = x/h

x = tan(60°)*h

Then our two catheti are h and tan(60°)*h.

This means that the area will be:

[tex]A = h*tan(60\°)*/2 = tan(60\°)*h^2/2[/tex]

Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).
