Write 2/15 as a decimal.
Cloud [144]
If you need to write a number as a decimal, it means that you need to write is a an x divided by a power of 10.
you can use this formula:
\frac{2}{15} = \frac{x}{10}

now let's multiply both sides by 10:
\frac{20}{15} = x
and simplyfy:
(by dividing the first fraction's elements by 5)
\frac{4}{3} = x

change improper fraction into a mixed number
1\frac{1}{3} = x

and 1 over 3 is 0.33333...

so the  answer is 1.333333 - we can also write it as 1.(3)

Given: △DMN, DM=10 3 m∠M=75°, m∠N=45° Find: Perimeter of △DMN
OlgaM077 [116]

Angle D is 180° -75° -45° = 60°. Drawing altitude MX to segment DN divides the triangle into ΔMDX, a 30°-60°-90° triangle, and ΔMNX, a 45°-45°-90° triangle. We know the side ratios of such triangles (shortest-to-longest) are ...

... 30-60-90: 1 : √3 : 2

... 45-45-90: 1 : 1 : √2

The long side of ΔMDX is 10√3, so the other two sides are

... MX = MD(√3/2) = 15

... DX = MD(1/2) = 5√3

The short side of ΔMNX is MX = 15, so the other two sides are

... NX = MX(1) = 15

... MN = MX(√2) = 15√2

Then the perimeter of ΔDMN is ...

... P = DM + MN + NX + XD

... P = 10√3 +15√2 + 15 + 5√3

... P = 15√3 +15√2 +15 . . . . perimeter of ΔDMN
