Héctor gastó en la entrada de cine una tercera parte del dinero con el que salió de casa. Con la cuarta parte del dinero compró una bolsa de palomitas y le sobraron 5 euros. ¿Con cuánto dinero salió de casa?

Answers

Answer:

Héctor salió de su casa con 12 euros.

Step-by-step explanation:

Cuando Héctor gastó en la entrada de cine una tercera parte del dinero con el que salió de casa, tenemos:

[tex] C = \frac{1}{3}x [/tex]    (1)

Cuando compró una bolsa de palomitas con la cuarta parte:

[tex] P = \frac{1}{4}x [/tex]    (2)                                  

Entonces al sobrarle 5 euros y relacionando las ecuaciones (1) y (2) con el monto inicial:

[tex] x - C - P = 5 [/tex]

[tex] x - \frac{1}{3}x - \frac{1}{4}x = 5 [/tex]

[tex] x = 12 [/tex]

Por lo tanto, Héctor salió de su casa con 12 euros.

Given the function
f(x)=-1/2(1-x)^2,
find f(-5).

Answers

Answer:

f(x)= -1/2(1-x)^2

replacing x with -5 since -5 was given as the function

f(-5)=-1/2(1-5)^2

according to bodmas we solve what is in the bracket first

f(-5)=-1/2(-4)^2

f(-5)=-1/2(16)

-1/2*16/1

HELP ME ASAP PLEASE!!!!!

Answers

Answer:

88

Step-by-step explanation:

46= x° ( isosceles angles )

Now, taking all side of the triangle

46+46+y =180 ( sum of all side of triangle )

or, y= 180 -92

y = 88°

ANSWER

y = 88

EXPLANATION: in an isosceles triangle the two base angles are equal so x is 46. If you add 46 + 46 you get 92 subtract 180 by 92 and you get 88. Which is y the vertex angle

find the composition of transformations that map ABCD to EHGF

Answers

Answer:

(x - 1, y + 1 )

Step-by-step explanation:

Consider the reflection in the y- axis

A point (x, y ) → (- x, y )

Consider the reflection of point A

A(- 5, 2 ) → A'(5, 2 )

Now A → E after the transformations

E = (4, 3 ), thus

A'(5, 2 ) → E(4, 3 )

(x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )

The translation rule is (x, y ) → (x - 1, y + 1 ).

What is Translation?

In mathematics, translation is a transformation that moves every point of a figure or a graph the same distance and in the same direction. The object being translated retains its size and shape, but its position changes.

Consider the reflection in the y- axis

A point (x, y ) → (- x, y )

Consider the reflection of point A

A(- 5, 2 ) → A'(5, 2 )

Now A → E after the transformations

E = (4, 3 ), then

A'(5, 2 ) → E(4, 3 )

Thus, the translation rule is (x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )

Assignment Summary For this assignment, you will construct a scientific model of the water cycle to show how water is recycled through an ecosystem. Once you have drawn your model on a poster board, you will write one to two paragraphs explaining how water is transferred within and between organisms and the environment. Background Information Water is a very important compound. Organisms need water to carry out life-maintaining processes such as growth and development. Without water, living things will not survive. Water continually flows among the atmosphere, land, water, and living organisms. This process, called the water cycle, allows water to be recycled as it moves through Earths spheres. Materials Assignment Instructions Step 1: For this project, you are expected to submit the following: 1. Your model of the water cycle 2. One to two typewritten paragraphs describing the water cycle Step 2: Prepare for the project. a) Read through the guide before you begin so you know the expectations of this project. Pay particular attention to the instructions you need to follow to create a model on your poster board. b) If anything is not clear to you, be sure to ask your teacher. Step 3: Gather materials for the model. a) Start with a blank poster board. Be sure to put your name on it. b) You may either draw the parts of the water cycle or print images to construct a model on your poster board. Gather any drawing tools that you will need, or print any images you want to use. Step 4: Create a model of the water cycle. a) Your model should include bodies of water such as lakes and oceans, organisms, air, and land. b) Draw arrows indicating how water moves within an ecosystem and between organisms and their environment. Be sure to include the Sun and gravity in your model. c) Include short phrases on your poster that summarize what occurs at each stage of the water cycle Step 5: Write a paragraph describing the water cycle. a) Type one to two paragraphs describing the full water cycle. Be sure to use full sentences and proper grammar.
