The two triangles below are similar. What is the ratio of the corresponding side lengths? 4:9 4:2 26:26 4.5:2

The thing is Similar Triangles

Answers

Answer 1

Answer:

4 : 2

Step-by-step explanation:

We are given ΔABC ≅ ΔA'B'C'.

When two triangles are congruent, their corresponding sides and angles are congruent.

Since, the sides of the triangles are in relation,

AB = 2 × A'B' and side BC = 2 × B'C' i.e. 4 = 2 × 2 and 9 = 2 × 4.5.

Therefore, the ratio of the corresponding sides are given by 4 : 2 and 9 : 4.5 i.e. 2 : 1.

Since, the ratio of the corresponding sides comes out to be 2 : 1 = 4 : 2.

Hence, the ratio of the corresponding sides is 4 : 2.

The square below represents one whole. What percent is represented by the shaded area?

Answers

Answer:

6%. There are 100 blocks, and 6 are shaded. 6 out of 100 is 6%

Hope this helps!

Count the smaller squares in the larger square. it is a 10 x 10 square so in total there are 100 small squares there is 100% in one whole so then 100% / 100 squares tells us how many percent is one square which is 1%

then you multiply one percent by how many squares there are so 1% x 6 is 6%

6% is the answer

What is the circumference and area of both pizzas?
will mark brainliest

Answers

To find circumference, you must multiply the diameter by pi, (roughly 3.14)
To find area, you can use the formula A=pi (radius) squared
Radius is half of diameter

For the large pizza, the circumference would be about 50.265. You can round this to ~50 inches.
The area would be about 201.06 inches. You can round this to 201 inches


For the medium pizza, the circumference would be about 37.69 inches. The area would be about 113.09 inches squared.

Robert places $500.00 in the bank for 5 years at a rate of 12%. How much interest will he earn at the end of the five years?

Answers

Answer:

97.6

Step-by-step explanation:

Answer:

381.17$

Step-by-step explanation:

the interset is 12% of the account so it increase with it, for example:

-year one: 500 * 12% = 60$

     the account become 560$

-year two: 560 * 12% = 67.2$

     the account is 627.2$ which is equal to 500 * (112%)^2

so in five years, the account become

500 * (112%)^5 = 881.17$

the interset in 5 years  = 881.17 - 500 = 381.17$

Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'. Which rule describes this transformation?
A: (x, y) → (x−5, y−3)
B: (x, y) → (x+5, y+3)
C: (x, y) → (x−3, y−5)
D: (x, y) → (x+3, y+5)

Answers

Answer:

B

Step-by-step explanation:

As Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P′Q′R′S′.

Therefore, we can conclude that the rule '' A rule for a translation right and up (x + __, y + __) '' describes this transformation.

The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.

Given that, quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'.

What is the translation?

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Translation rules:

When the shape is moved towards the right by k units, then replace x with x + k.

When the shape is moved up by k units, then replace y with y + k.

So, translated 5 units to the right

x → x+5

Translated 3 units up

y → y+3

The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.

What Is It That You Really Need?Sometimes it seems as if we never get what we want. But sometimes when we do get what we want, we realize that its not what we really want. Thats because our wants dont always match our needs. The solution to this problem is to try to understand and satisfy our real needs.Psychology is the scientific study of the human mind and human and animal behavior. A lot of psychological research has been done about human needs and how they should be satisfied. Studies have shown that humans have basic needs that must be consistently met. Studies have also shown that there is an order of importance in which these needs must be satisfied. An individuals basic functional needs must be satisfied before he or she can go on and meet other more creative and self-fulfilling needs.Abraham Harold Maslow (19081970) was an important psychologist who became famous for his studies regarding human needs and wants. He wrote two major works, Motivation and Personality and Toward a Psychology of Being. Maslow stressed that basic needs must first be satisfied before a person is able to be creative or function independently. He created his famous hierarchy of needs theory, which separates human needs into five layers. Each layer in the hierarchy must be satisfied before a person can proceed to the next layer. The five layers of human needs, according to Maslow, are as follows:1. the physiological needs2. the safety and security needs3. the love and belonging needs4. the esteem needs5. self-actualizationThe Physiological NeedsThe physiological needs include the basic requirements for physical survival, such as oxygen, water, protein, salt, sugar, minerals, and vitamins. Other physiological needs include a proper body temperature and pH balance, physical activity, a lack of pain, and adequate sleep.The Safety and Security NeedsThese needs become relevant only after the physiological needs are largely satisfied. The person will then become increasingly interested in such things as being safe and protected and having a stable life. He or she might also begin to need structure and order.The Love and Belonging NeedsOnce a person feels reasonably secure in life and has his or her basic bodily needs satisfied, he or she wants to be a part of a community or group, to have friends, and to be in loving and caring relationships.The Esteem NeedsThis level of needs has two components. The first covers a persons needs to be respected by others and achieve fame, attention, and dignity. The second component of this level of needs covers a persons needs for self-respect, confidence, independence, and freedom.Self-ActualizationThe highest level is different from the other levels in a crucial way. All the previous levels discuss needs that need to be satisfied; once they are satisfied, we no longer think about them. If we feel well fed, safe, appreciated, and confident, we dont think about those needs anymore. But on the complex level of self-actualization, a person continues to feel this need even after he or she has achieved it. This need drives us to be the most complete people we canto be the best that we can be.The next time you are feeling as if something is missing from your life, think about Maslow and his theory of needs. Have you really satisfied the basic needs before trying to satisfy the higher levels of needs? Maybe you need to redefine what you are really searching for.Select the correct answer.Why does the writer mention each need in the same order as Maslow's hierarchy?A. to reinforce the meaning of the contentB. to create an orderly writing styleC. to create a memory deviceD. to show agreement with Maslow's theory Fill in the blank with the correct demonstrative article: ____chemisececettecetces Program with variables upload instructions A few years ago the population of male blue moon butterflies on the island of Samoa declined.
