Describe how to write 6,397,000,000 in scientific notation. Complete the description.

First move the decimal point
places to the left to find
, a number that is greater than or equal to 1 and less than 10. Then multiply
by 10
, using an exponent on 10 that equals the number of places you moved the decimal.

very eassy 6.3970*10^9

Step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
