Answer:

The answer is 3.2 E 3 or 3.2 x 10^3

You move back 3 spaces which is 3.2, since you moved back 3 spaces, you put 3 as the power/exponet.

To be more satisfied, 3.2 is your base number, it is the big number Below the power/exponent. The power/exponent is 3, you moved 3 spaces and you moved to the left, so it is represented as a positive power/exponent.

Hope this helps.

Mary bought a dozen eggs at the shop she used third of dozer for breatest and quarter for breakfast. How many eggs are left?show

sveta [45]

When numbers are grouped in twelves, each group is referred to as a dozen.

<em>There are 5 eggs left</em>

The amount of egg she bought is:

$\mathbf{Amount = 1\ dozen}$

Third of a dozen for breatest, means:

$\mathbf{Breatest = \frac4{12}}$

Quarter for breakfast, means:

$\mathbf{Breakfast = \frac1{4}}$

So, the fraction of eggs left is:

$\mathbf{Eggs = Amount - Breatest -Breakfast }$

This gives:

$\mathbf{Eggs = 1 - \frac{4}{12} - \frac{1}{4}}$

Take LCM

$\mathbf{Eggs = \frac{12 - 4 - 3}{12}}$

$\mathbf{Eggs = \frac{5}{12}\ dozen}$

<em>1 dozen means 12.</em>

So, we have:

$\mathbf{Eggs = \frac{5}{12} \times 12}$

$\mathbf{Eggs = 5}$

Hence, she still has 5 eggs left

Jim drove 168 miles in 4hr. If he can keep the same pace, how long will it take him to drive 504 miles

Jobisdone [24]

Since he went 168 miles in 4 hours, then his speed is 42 mph. Then, 504 divided by 42 is 12. It will take 12 hours at a steady pace of 42 mph to reach 504 miles.
