80 ! write the standard form for the scientific notation give below: 2.32 x 103 = 4.2 x 104 = 4.2 x 10-2 = write this number in scientific notation: 5,700 tip: the first number must be 1 or more, but less than ten. write this number in scientific notation: 6,548,000

2.32*103 = 2.39E3, or 2.39*10^3

This result is likely wrong because I first thought your 103 literally meant 103.  Now it seems that you meant 10^3 (10 to the third power).  So, ignore the above result and multiply again:  2.32*10^3.  This is already in scientific notation.

4.2*10^4 is already in scientific notation.

4.2*10^(-2) is already in scientific notation.

5700=1.7*10^3 (answer in scientific notation)

6548000= 6.55*10^(-6) (in scientific notation)

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
