What is a rational number equivalent to 3.12 with a line over 12

Answers

To answer this problem, note that the line over 12 signifies that the numbers are repeating. This means that the number is 3.12121212...

To convert the item to a rational number, divide the repeating digits with 9. In this case, since the repeating digits are 1 and 2, divide 12 by 99. The rational number then becomes 3 12/99. Simplifying further the fraction gives 4/33. Thus, the answer is 3 4/33.

A rational number equivalent to 3.12 with a line over 12 is: 103/33

How to Identify a Rational Number?

A rational number is defined as any number that can be written as a fraction, where both the numerator (the top number) and the denominator (the bottom number) are integers, and the denominator is not equal to zero.

In other words, a rational number can be expressed as p/q, where p and q are both integers and q ≠ 0.

A rational number equivalent to 3.12 with a line over 12 is 3 + 12/100.

The line over 12 indicates that 12 is repeating infinitely, so the decimal representation is 0.121212... (with 12 repeating).

To convert this repeating decimal to a rational number, we can use the following method:

Let x = 0.121212...

Multiply both sides of the equation by 100 to shift the repeating part two decimal places to the left:

100x = 12.121212...

Now, subtract the original equation from the shifted equation to eliminate the repeating part:

100x - x = 12.121212... - 0.121212...

99x = 12

Finally, divide both sides by 99 to solve for x:

x = 12/99 = 4/33

So, the rational number equivalent to 3.12 with a line over 12 is 3 + 12/100 = 3 + 4/33 = 103/33

An exterior angle of a triangle is 140 degrees. If the non-adjacent angles are congruent, then what are the measures of all of the interior angles of the triangle?

Answers

The measures of all of the interior angles of the triangle are 70 degrees, 70 degrees and 40 degrees

Solution:

Given that exterior angle of triangle is 140 degrees

The exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles

Given that adjacent angles are congruent

Let one of the non adjacent interior angles be "x"

x + x = 140

2x = 140

x = 70

So the two interior angles are 70 degrees and 70 degrees

Let us find the third interior angle

The angle sum property of a triangle states that the interior angles of a triangle always add up to 180 degrees

70 + 70 + third angle = 180

third angle = 180 - 70 - 70

third angle = 180 - 140

third angle = 40 degrees

Thus the measures of all of the interior angles of the triangle are 70 degrees, 70 degrees and 40 degrees

What is the area of a parallegram that has a base of 12 3/4 in and a height of 1/2 in

Answers

So the parallelogram Formula is B×H
Plug in
12 3\4 ×1\2
51\4 × 1\2
51\8 = 6.375
So if you solve you will be gated 6.375

area=base times height
base=12 and 3/4
height=1/2
area=12 and 3/4 times 1/2
12 and 3/4=12+3/4
area=(12+3/4) times 1/2
distribute using distributive propery a(b+c)=ab+ac
area=12 times 1/2+3/4 times 1/2
area=6+3/8
area=6 and 3/8 square inches (square inches=in^2))

The coordinates of a triangle are A(4,5) B(-1,4) C(2,-3)
after a translation of up 3 minus 4 what would be the new coordinates

Answers

After translation of up 3 and bottom 4, all the x-coordinates will increase by 3, and all the y-coordinates will decrease by 4.

Coordinates would be: A(4+3,5-4), B(-1+3,4-4), C(2+3,-3-4)
So, Final answer would be: A(7,1) B(2,0) C(5,-7)

Hope this helps!

A (0,8)
B (-5,7)
