What are all the fractions that are between 1/2 and 1.
Oksanka [162]

Answer:

2/4, 3/5,3/4, 2/3,13/25, 27/50 11/20, 14/25, 29/50,31/50, 63/100,16/25,33/50,17/25,7/10,18/25,37/50,19/25,77/100,39/50,4/541/50, 83/100, 21/25 , 17/20, 43/50 , 87/100,22/25,9/10, 91/100, 23/25, 93/100, 47/50, 19/20 , 24/25  97/100, 49/50,99/100(note that I did not state all the fractions between 1/2 and 1)

Step-by-step explanation:

Firstly one half(1/2) represents 0.50 as a decimal and 1 would be 1.00

This is like saying finding Fractions that give you percentages between 50% and 100%

for example:

you could simplify 52/100 and get 31/50

31/50 as a decimal would be 0.52  and 0.52 falls between(0.50 and 1.00) 1/2 and 1

example 2: 89/100= 0.9 (same as0.90) and [90/100] is same as 9/10 = 0.9

0.90 or 0.9 (zero point nine) is not the same as 0.09(zero point zero nine

If you are using a casio calculator, you can simplify the fraction by putting in your numerator then pressing |a b/c| button then enter the denominator, then the calculator should simplify the fraction, if the fraction remains the same, this means that it cant be further simplified.if your calculator has

| a b/c| then you can also use it.

or use an online calculator or simplify if you wish

To <em>find the decimal of that fraction you can simply divide the numerator by the denominator, Example; 82/100 is same as 0.82 and 41/50 is same as 0.82.</em>

Prove that there are no solutions in integers x and y to the equation 2x^2 + 5y^2 = 14
iren [92.7K]
Solve the equation for y using the formula for slope: y + mx + b

2x^2 + 5y^2 = 14
5y^2 = -2x^2 + 14
y^2 = -2/5x^2 + 14/5
y = the sq root of -2x^2/5 + 14/5

There is no integer solution to the square root of a negative number.

A line is perpendicular to y = -1/5x+1
natta225 [31]

Answer:

y = 5\, x + 26.

Step-by-step explanation:

Start by finding the slope of the line perpendicular to y = (-1/5)\, x + 1.

The slope of y = (-1/5)\, x + 1 is (-1/5).

In a plane, if two lines are perpendicular to one another, the product of their slopes would be (-1).

Let m denote the slope of the line perpendicular to y = (-1/5)\, x + 1. The expression (-1/5)\, m would denote the product of the slopes of these two lines.

Since these two lines are perpendicular to one another, (-1/5)\, m = -1. Solve for m: m = 5.

The (-5,\, 1) is a point on the requested line. (That is, x_{1} = -5 and y_{1} = 1.) The slope of that line is found to be m = 5. The equation of that line in the point-slope form would be:

y - 1 = 5\, (x - (-5)).

Rewrite this point-slope form equation into the slope-intercept form:

y = 5\, x + 26.
