Ascientist measured the wavelength of an x-ray as 0.65 meters. write the number in scientific notation.

Step-by-step explanation:

The scientific notation of a number is to express the number in the form where x is the base of ten.

So, if we want to express the number 0.0000000065, then we can write it as

.

So, we can write 0.0000000065 as or but those are not the scientific notation.  

Therefore, is the scientific notation of 0.0000000065. (Answer)

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
