Step-by-step explanation:
Count the number of times you have to move the decimal point to the right until it is to the right of the 1st nonzero number.
a) You have to move the decimal point 11 times until it gets to the right of the 1st nonzero number, which is 7. You then rewrite this number as
The exponent of 10 is a negative number because you moved the decimal point to the right.
b) Similarly, you have to move the point 9 times to the right so the answer is
Answer:
0.333
Step-by-step explanation:
Answer:
Road C is 1.5 mi east of Road A
Step-by-step explanation:
we know that
Road B is 4.6 mi east of Road A
Road C is 3.1 mi west of Road B
so
Road C is between Road A and Road B
AB=4.6 miles
CB=3.1 miles
AB=AC+CB
Solve for AC
AC=AB-CB
AC=4.6-3.1=1.5 miles
therefore
Road C is 1.5 mi east of Road A
Answer:
z≥−3
Step-by-step explanation:
1 Subtract 88 from both sides.
5z≥−7−8
2 Simplify -7-8−7−8 to -15−15.
5z≥−15
3 Divide both sides by 55.
z≥− 15/5
4 Simplify 15/5 to 3
z≥−3
