In a computer art program, when you click and drag on a side of a photograph, you distort it. But when you click and drag on a corner of the photograph, it remains proportional to the original.

Proportion is defined as the comparative relationship among various elements of  an image. 
Simply taking a picture of jpj or png format, if the side of the picture is drag in or drag out, then the picture got disturbed, but if the same picture is drag in or drag out by its corner, then the picture composition remains the same, and thus the proportions of all the pigments remains the same. 
Another example is that of using an equal proportionate amount of different colors in an image, otherwise the picture will not show its true essence and the proportionality factor among various colors of an image become the base of its originality.

3+-√(-3)^2 - 4(5)(-1)
Alona [7]

Answer:

Step-by-step explanation:

Easy way to do this is step by step.  Your quadratic, from your entry, must be

5x^2-3x-1.

Step by step looks like this, one thing at a time:

x=\frac{3+\sqrt{(-3)^2-4(5)(-1)} }{2(5)} becomes

x=\frac{3+\sqrt{9-(-20)} }{10} becomes

x=\frac{3+\sqrt{9+20} }{10}

and this of course is

x=\frac{3+\sqrt{29} }{10}

Do the same with the subtraction sign to get the other solution.

If you're unsure of how to enter it into your calculator, do it step by step so you don't mess up the sign.  If you enter it incorrectly, you could end up with an imaginary number when it should be real, or a real one that should be imaginary.

Just my advice as a high school math teacher.

You have total coins for a total of $. . You only have quarters and dimes. Let represent the number of quarters and represent th
Sonja [21]

Answer:

Quarters = 41

Dimes = 18

Step-by-step explanation:

Given

Coins = 59

Worth = \$12.05

d = dimes

q = quarters

Required

The number of each coin

The total coins can be represented as:

d + q = 59

1\ quarter = \$0.25 \\ 1\ dime = \$0.10

So, the worth of the coin is:

0.25q + 0.10d = 12.05

The equations to solve are:

0.25q + 0.10d = 12.05

d + q = 59

Make d the subject in: d + q = 59

d =59 - q

Substitute d =59 - q in 0.25q + 0.10d = 12.05

0.25q + 0.10(59 - q) = 12.05

0.25q + 5.9 - 0.10q = 12.05

Collect like terms

0.25q  - 0.10q = 12.05 - 5.9

0.15q = 6.15

Solve for q

q=\frac{6.15}{0.15}

q=41

Substitute q=41 in d =59 - q

d = 59 - 41

d = 18

So:

Quarters = 41

Dimes = 18

Ms.Ellis has a crate that is 5 feet tall, 6 feet wide, and 8 feet long. How many square feet of paint does she need to cover the
Vladimir [108]

Answer:

The answer to your question is 236 ft²

Step-by-step explanation:

Data

height = 5 ft

width = 6 ft

length = 8 ft

Area = ?

Process

I will consider that the crate is a rectangular prism which has 6 sides

1.- Find the area of the sides that measure 8 x 6

Area = 2 (8 x 6)

        = 2(48)

        = 96 ft²

2.- Find the area of the sides that measure 8 x 5

Area = 2(8 x 5)

Area = 2(40)

Area = 80 ft²

3.- Find the area of the sides that measure 6 x 5

Area = 2( 6 x 5)

Area = 2(30)

Area = 60

4.- Find the total area

Area = 96 + 80 + 60

Area = 236 ft²

5.- Conclusion

She needs 236 ft² of paint
