.46 repeating as a fraction in simplest form

Mathematics
1 answer:
My name is Ann [436]3 years ago
4 0

Answer:

7/15

Step-by-step explanation:

0.4 6  =  0 . 6  - 0.2

0.46  = 6/9 ⋅ 0.9 - 0.2

0.46 = 6/9 - 1/5

0.46 = 2/3 - 1/5

0.46 = 10/15 - 3/15

0.46 = 7/15

Note that  7  and  15  have no common factors larger than  1 , so this is in simplest terms.

forsale [732]

Answer:

At 7% $54,000

At 9% $156,000

Step-by-step explanation:

Let x be the amount invested at 7%, Then 2x + 48000 will be the amount invested at 9%

We know that:

7% = 0.07 & 9% = 0.09

So we can write the interest equation as follows:

0.07x + 0.09 (2x + 48000) = 17820

0.07x + 0.18x + 4320 = 17820

0.25x + 4320 = 17820

Subtracting 4320 from both sides of the equation we get:

0.25x = 17820 - 4320

0.25x = 13500

Dividing both sides of the equation by 0.25 we get:

x = 13500 / 0.25

x = $54,000 invested at 7%

&

2 x 54000 + 48000

= $156,000 invested at 9%

Hence the amount invested at 7% is $54,000.

& the amount invested at 9% is $156,000.

How to calculate the distance for graphs?
ollegr [7]

Answer:

\sqrt{(x1-x2)^{2}+(y1-y2)^{2} }

Step-by-step explanation:

This is the distance formula for cartesian coordinate systems, or your typical xy graph. If given two points to find the distance between, you can assign '1' or '2' to the points, i.e. (1,1) and (2,2) could be: (1,1) is (x1,y1) and (2,2) is (x2,y2). It doesn't matter which point is 1 or 2. If we were to use those example points in this formula, we would have:

\sqrt{(1-2)^{2}+(1-2)^{2}}

We can simplify and come up with:

\sqrt{(-1)^{2}+(-1)^{2}}

=\sqrt{2}

We must remember that square roots can be positive OR negative, HOWEVER, because you are looking for a distance it must be positive \sqrt{2}.

Hope this helped!

What is the measure of the missing angle?
mestny [16]

Answer:

25°

Step-by-step explanation:

These types of figures have 3 angles, which add up to 180°. If you found the 2 angles already, you can find the last one by adding both angles together and using 180° to deduct it with the total degree of thd 2 angles.

127 + 28 = 155

180 - 155 = 25
