Answer:
When reading decimal numbers, read the whole number part as normal, use "and" to represent the decimal point and continue reading the number as normal, but end with the last place value.
For example: how do you read 36.57 --> thirty-six and fifty-sevens hundredths
When writing decimals it is like reading them. You write the whole part as normal, and write a decimal to represent where you would say "and". Continue writing the number.
For example: Write eighty-five and sixty-four hundredths --> 85.64
Step-by-step explanation:
The answer is 58 i hope this helped you and didn’t make you fail lol
Answer:
Length of DE is : 18√2 units
Step-by-step explanation:
The length of a side of a triangle is 36.
To calculate : The length of the segment DE
Now, the two parts of triangle have equal area ∴ Area(ADE) = Area(BDEC)
![\implies Area(ADE)=\frac{1}{2}\times Area(ABC) \\\\\implies \frac{Ar(ADE)}{Ar(ABC)}=\frac{1}{2}](https://tex.z-dn.net/?f=%5Cimplies%20Area%28ADE%29%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20Area%28ABC%29%20%5C%5C%5C%5C%5Cimplies%20%5Cfrac%7BAr%28ADE%29%7D%7BAr%28ABC%29%7D%3D%5Cfrac%7B1%7D%7B2%7D)
In ΔABE and ΔABC,
∠A = ∠A (Common angles)
∠ABE = ∠ABC (Corresponding angles are always equal)
By AA postulate of similarity of triangles, ΔABE ~ ΔABC.
Hence by area side proportionality theorem
![\frac{Ar(ADE)}{Ar(ABC)}=(\frac{DE}{BC})^2\\\\\implies \frac{1}{2}=\frac{DE^2}{36^2}\\\\\implies DE^2=\frac{36^2}{2}\\\\\bf\implies DE=18\sqrt{2}\textbf{ units}](https://tex.z-dn.net/?f=%5Cfrac%7BAr%28ADE%29%7D%7BAr%28ABC%29%7D%3D%28%5Cfrac%7BDE%7D%7BBC%7D%29%5E2%5C%5C%5C%5C%5Cimplies%20%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7BDE%5E2%7D%7B36%5E2%7D%5C%5C%5C%5C%5Cimplies%20DE%5E2%3D%5Cfrac%7B36%5E2%7D%7B2%7D%5C%5C%5C%5C%5Cbf%5Cimplies%20DE%3D18%5Csqrt%7B2%7D%5Ctextbf%7B%20units%7D)
Hence, length of DE is 18√2 units
