So to decompose means to break down. They may be talking about breaking up the number by what "place" it's in.

example given:

1,239 = 1,000 + 200 + 30 + 9

example given:

1,239 = 1,000 + 200 + 30 + 9

So because there are 4 squares like 4 parts of this figure and just one is shaded so the right answer will be 1/4 what mean 1 from 4 is the shaded part

so choice D. is right

hope this will help you

QUESTION POSTED AT 25/01/2020 - 03:30 PM

**Answer:**

**$1.75**

**Step-by-step explanation:**

Let x be the cost of 1 drink

Cost of 3 drinks = $3x

Cost of 4 drinks = $4x

Let y be the cost of 1 soft pretzels.

Cost of 3 soft pretzels=$3y

Cost of 2 soft pretzels=$2y

Now we are given that One person purchased 3 drinks and 3 soft pretzels. Another person purchased a total of $9.00.

**So, equation becomes : --1**

Now we are given that Another person purchased 4 drinks and 2 soft pretzels for a total of $8.50.

**So, equation becomes : --2**

Solving 1 and 2 graphically

Intersection point provides the answer of the system of equations

Refer the attached graph

**Intersection point : (1.25,1.75)**

**Hence the price of one soft pretzel is $1.75**

**Answer:**

**Option A. 35 + 3x = 83**

**Step-by-step explanation:**

Emma took 35 picture of flowers on a nature walk.

She took 3 pictures of each bird she saw.

If x be the number of birds she saw during her nature walk. then total picture of birds = 3x

Total pictures taken by her were = 83

Therefore, total pictures of flowers + total pictures of birds = 83

(35 + 3x = 83 )

**Option A 35 + 3x = 83** is the answer.

Each side of the square needs to be enlarged by x inches to obtain the new area which is 81. The area of the square is calculated by squaring the measure of its side.

A = (x + 4)²

From the given value of area,

(x + 4)² = 81

x ² + 8x + 16 = 81

Further simplification leads to the answer,

x² + 8x - 65 = 0

A = (x + 4)²

From the given value of area,

(x + 4)² = 81

x ² + 8x + 16 = 81

QUESTION POSTED AT 21/01/2020 - 09:53 AM

I don't know how to draw a picture for you in this space as you asked. So, stay with me. It's a combination of BASIC geometry principles, a little algebra and, of course, simple logic.

1. Draw a vertical line from the top angle straight down. That creates 2 triangles. The newly created angles are each 90 degrees because you've created two right angles at the bottom.

2. Since the three angles of any triangle need to add up to 180 degrees, work backwards. If one angle is 90 degrees, the other two need to add up together to be 90 degrees to equal 180.

3. Start with 3x-4. Logically speaking, the angle (visually) is probably around 45 degrees because it looks like about half the size of the 90 degree angle. Start with that premise. Plug in a number to the equation that equals about that number. I chose 15. 3(15)-4 = 41. OK. If the top angle (of this newly created triangle on the left) PLUS the 41 need to add up to 90, do the subtraction.... 90-41= 49.

4. Let's move to other triangle. We know the bottom angle is 90 and PART of the top angle is 49. Again, logically and visually suppose that that far right angle is about 30 degrees - because it's skinnier than the far left 41 degree angle AND.... we could say the angle is 30 degrees because 2(15) = 30. Remember that we plugged in 15 for x in the other equation.

5. Again, do the subtraction. If one angle is 90, the second is 30, what's the difference from 180? 60. So, that top angle (of the newly-created triangle on the right is 60 .... PLUS the 49 that got from the partial angle before = 60 + 49 = 109. So the FULL angle at the top is 109 degrees. AND, we know that's right because we can check it by plugging in the number 15 into the equation like this: 8x-11.... 8(15) - 11 = 120 - 11 = 109.

6. As the measure of the largest angle is 109 degrees, the answer is B.

QUESTION POSTED AT 21/01/2020 - 09:26 AM

We'll first clear a few points.

1. A hyperbola with horizontal axis and centred on origin (i.e. foci are centred on the x-axis) has equation

x^2/a^2-y^2/b^2=1

(check: when y=0, x=+/- a, the vertices)

The corresponding hyperbola with vertical axis centred on origin has equation

y^2/a^2-x^2/b^2=1

(check: when x=0, y=+/- a, the vertices).

The co-vertex is the distance b in the above formula, such that

the distance of the foci from the origin, c satisfies c^2=a^2+b^2.

The rectangle with width a and height b has diagonals which are the asymptotes of the hyperbola.

We're given vertex = +/- 3, and covertex=+/- 5.

And since vertices are situated at (3,0), and (-3,0), they are along the x-axis.

So the equation must start with

x^2/3^2.

It will be good practice for you to sketch all four hyperbolas given in the choices to fully understand the basics of a hyperbola.

To determine the cost of manufacturing one picture frame, add all the known cost by the number of frames produced. With the basis of one hour of operation,

Cost of wood per frame = $18.75 / 15 = $1.25

Cost of direct labor per frame = $ 13.50 / 65 = $ 0.21

Adding all up the costs,

total cost = $1.25 + $0.21 = $1.46

Therefore, manufacturing one picture frame costs approximately $1.46.
