Please help me with the following (1-5) Write the following numbers in scientific notation.

1. 405 352 cm =

2. 7.6352 x 10-3 kg =

3. 3.1 x 104 mm + 4.87 x 105 mm =

4. (4.8 x 105 km) x (2.0 x 103 km) =

5. (3.3 x 10-4 mL) ÷ (1.1 x 10-6 mL) =

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

The domain is 100 becuase i said so ok. jk its 00 jk again its r jk again and again its 75jk im always kiffing okaydbdbekufir83gc84vrudnmm as 8ehehenenrn vr 0eh339520252026ee6ee8e9
