How can I use the golden ratio? Need this answer, stop putting false please.
natulia [17]

Hey, this is photography right?

Step 1: Evaluate the scene

Exactly how you use the golden ratio depends on the scene in front of you. Composition techniques are there to help you think about the scene instead of just pointing and shooting.

Step 2: Determine whether to use the golden ratio or the golden spiral (or even the Rule of Thirds)

Next, choose between the golden spiral and the phi grid. You can’t contort a straight object to fit inside a spiral, so if your scene has great leading lines, try the phi grid.

Step 3: Imagine the overlay and shoot

Imagining a complex spiral aligned over your photo can be tricky at first. If you simplify the concept, it’s a bit easier to manage.

First, check and see which grid overlays your camera has built-in by viewing the options in settings. If your camera has a phi grid or spiral option, turn that feature on. Most will have the Rule of Thirds. Even when that isn’t the composition guide you are using, it’s helpful to enable that feature.

Step 4: Edit

Picturing the phi grid or golden ratio spiral as you shoot is one thing, but what if you want that exact 1.618 magic number? Thankfully Photoshop  (and several other photo editors) have tools for that.

Hope this helped!

An art supply store sells posters for $9 each and pictire frames for $15 each
77julia77 [94]
Since posters cost 9 dollars each and picture frames cost 15, it would be multiplication.

The expression would be 9(6)+15(6) or 9x6+15x6.

You have to multiply these numbers. 9 times 6 would be 54. 15 times 6 would be 90.

Now, we need to add these together. 54 plus 90 would be 144.

The total cost for 6 framed posters would be $144.

Help me please!!!!!!
Setler [38]

Answer:

40

Step-by-step explanation:

1. multiply all terms by the same value to eliminate fraction denominators (n times 5/8 = n times 25/n)

2. cancel multiplied terms that are in the denominator (n times 5/8 = 25

3.re order terms so constants are on the left (5/8n =25)

4. combine multiplied terms into a single fraction (5n/8 = 25)

5. multiply all terms by the same value to eliminate fraction denominators (8 times 5n/8 = 8 times 25)

6. cancel multiplied terms that are in the denominator (5n=8 times 25)

7. multiply the numbers (5n = 8 times 25 5n= 200)

8. simplify (n=40)
