What is the scientific notation for 950?

To find a, take the number and move a decimal place to the right one position.

Now, to find b, count how many places to the right of the decimal.

There are 2 places to the right of the decimal place.

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 9.5 (Please notice any zeroes on the end have been removed)

b = 2

Now the whole thing:

9.5 x 102

Check your work:

102 = 100 x 9.5 = 950

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

answer: it's d
