The polygons in each pair are similar. Find the missing side length.

Mathematics

Answer:

Step-by-step explanation:

If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.

Now use that scale factor, 4/5, to find the missing length

4/5 = ?/15

5*3 = 15 so 4*3 = ?

? = 12

aragraphs are the building blocks of papers. Many students define paragraphs in terms of length: a paragraph is a group of at least five sentences, a paragraph is half a page long, etc. In reality, though, the unity and coherence of ideas among sentences is what constitutes a paragraph. A paragraph is defined as “a group of sentences or a single sentence that forms a unit” (Lunsford and Connors 116). Length and appearance do not determine whether a section in a paper is a paragraph. For instance, in some styles of writing, particularly journalistic styles, a paragraph can be just one sentence long. Ultimately, a paragraph is a sentence or group of sentences that support one main idea. In this handout, we will refer to this as the “controlling idea,” because it controls what happens in the rest of the paragraph.

Miguel and his brother Ario are both standing 3 meters from one side of a 25-meter pool when they decide to race. Miguel offers

Westkost [7]

Answer:

Miguel start to swim when Ario has traveled 4.4 m.

Step-by-step explanation:

The total lenght of the pool is 25.

Since both of them standing 3 m from one side of the pool, then, the total distance both need to cover is $25-3$ m= 22 m.

Assume that the distance traveled by Ario before Miguel start to swin is $x$ . That means, the remaining distance to Ario (to cover the total size of the pool) is $22-x$ .

Then, in acoordance to the problem, the ratio between these two distances must be equal to 1/4.

That is,

$\frac{x}{22-x}=\frac{1}{4}$ .

So, we need to obtain $x$ from this equation. We must note that $x\neq 22$ , otherwise we have a zero in the denominator.

So, we rearrange the equation,

$4x=22-x$ (Multiplying both sides of equation by ( $4(22-x)$ ).

Then, $5x=22$ .

Therefore, $x=4.4$ m.

Riley has a farm on a rectangular piece of land that is 200200200 meters wide. This area is divided into two parts: A square are

777dan777 [17]

Answer:

The inequality that models the situation for her to have money to save is

7L² > 3(200L - L²)

On simplifying and solving,

L > 60 meters

Step-by-step explanation:

The length of her farm = L meters

The farm where she grows avocados is of square dimension

Area of the farm = L × L = L²

The piece of land is 200 m wide.

Total area of the piece of land = 200 × L = (200L) m²

If the area of her farm = L²

Area of the side where she lives will be

(Total area of the land) - (Area of the farm)

= (200L - L²)

= L(200 - L)

Every week, Riley spends $3 per square meter on the area where she lives, and earns $7 per square meter from the area where she grows avocados.

Total amount she earns from the side she grows the avocados = 7 × L² = 7L²

Total amount she spends on the side where she lives = 3 × (200L - L²) = 3(200L - L²)

For her to save money, the amount she earns must be greater than the amount she spends, hence the inequality had to be

(Amount she earns) > (Amount she spends)

7L² > 3(200L - L²)

To simplify,

7L² > 3L(200 - L)

Since L is always positive, we can divide both sides by L

7L > 3(200 - L)

7L > 600 - 3L

10L > 600

L > 60 meters

Hope this Helps!!!

Write an equation in slope intercept form for the line that contains the given point and is parrallel to the given line (0,4),Y=

Ilya [14]

Answer:

y = ½x + 4

Step-by-step explanation:

4 = ½[0] + b

4 = b

Parallel lines have SIMILAR RATE OF CHANGES [SLOPES], so the 4 remains in the m spot, plug in the ordered pair into the equation, then solve for b. This is your new equation once done:

y = ½x + 4

A tree has 99,400 leaves before autumn. Once autumn begins, the number of leaves on a tree decreases at a rate of 13% per day. A

SCORPION-xisa [38]

The answer to this question would be: D.99,400 * (0.87)^t < 12,000; 16 days
In this question, the initial number of leaves is 99,400 and it will decrease by 13% each day. Decrease by 13% can be put become: 100%-13%=87% of the original number.

Then, the function for the number of the leaves should be:
99,400 * (0.87)^t

to find how many days after autumn that the tree leaves is less than 12,000 the calculation should be:
99,400* (0.87)^t <12,000
(0.87)^t< 0.1207

The smallest number would be (0.87)^16= 0.10772290133
