Consider these three numbers written in scientific notation: 6.5 × 103, 5.5 × 105, and 1.1 × 103. which number is the greatest, and by how many times is it greater than the smallest number?

a.
the greatest number is 5.5 × 105. it is 5 times greater than the smallest number.
b.
the greatest number is 6.5 × 103. it is 50 times greater than the smallest number.
c.
the greatest number is 5.5 × 105. it is 500 times greater than the smallest number.
d.
the greatest number is 6.5 × 103. it is 5,000 times greater than the smallest number.
e.
the greatest number is 5.5 × 105. it is 5,000 times greater than the smallest number.

C.

Step-by-step explanation: The greatest number is 5.5 × 105. It is 500 times greater than the smallest number.

This is the correct answer on the test!

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
