1/4 it is just like having 4 quarters so if you have for quarters get them and lay them on down and 0.25 is 1 quarter.

Any percentage (less than 100% obviously) can be written as:

The percentage (in this case 25) over 100. ( $\frac{25}{100}$ )

However, this fraction can be simplified. If you divide the top number (the numerator) and the bottom number (the denominator) by 25, you get the fraction in its simplest form, which is $\frac{1}{4}$ .

Obviously, this only works with some numbers, where both the numerator and denominator are divisible by a common factor. For example, if you have a fraction like 9/16, you can't divide it any further - 9/16 is the simplest form. However, due to 25 and 100 both having 25 as a common factor, you can get 1/4.

Consider the equations y = √x and y = x^2 - 1

lord [1]

<h3>Answer:</h3>

(x, y) ≈ (1.49021612010, 1.22074408461)

<h3>Explanation:</h3>

This is best solved graphically or by some other machine method. The approximate solution (x=1.49, y=1.221) can be iterated by any of several approaches to refine the values to the ones given above. The values above were obtained using Newton's method iteration.

_____

Setting the y-values equal and squaring both sides of the equation gives ...

... √x = x² -1

... x = (x² -1)² = x⁴ -2x² +1 . . . . . square both sides

... x⁴ -2x² -x +1 = 0 . . . . . polynomial equation in standard form.

By Descarte's rule of signs, we know there are two positive real roots to this equation. From the graph, we know the other two roots are complex. The second positive real root is extraneous, corresponding to the negative branch of the square root function.

Gary took 7 hours to mow 4 lawns,then at that rate, how many lawns could be mowed in 35 hours? Write a different question plz

Svetach [21]

Answer:

The total amount of lawns to be mowed would be 20 in 35 hours.

Step-by-step explanation:

It takes an hour and 45 minutes to mow one lawn. When you multiply the 7 hours by 5 you get 35 hours. Same thing if you multiply the 4 lawns by 5 you get 20 lawns.

(5x+3)(7x-7) how do find x

Delvig [45]

We can use the FOIL method to solve.

(5x + 3)(7x - 7)

(5x * 7x) + (5x * -7) + (3 * 7x) + (3 * -7)

35x - 35x + 21x - 21

0 + 0

Best of Luck!
