Answer:

The answer is 2.077 × 10 ^-4

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps!

willhelmina has 8.3 ounces of peanut butter if she makes 5 sandwiches with an equal amount of peanut butter on each how much pea

nadezda [96]

Answer:

Wilhelmina will put 1.66 ounces of peanut butter on each sandwich.

Step-by-step explanation:

Given:

Ounces of peanut butter Wilhelmina has = $8.3$

Number of sandwiches prepared by her = $5$

According to the question:

She puts equal amount of peanut butter on each sandwiches.

So,

We have to find the quantity of peanut butter used for each sandwiches.

Here the distribution is equal so we have to use division method.

Let ounces of peanut butter applied on each sandwich be 'x'

⇒ $x= \frac{Ounces\ of\ peanut\ butter}{No.\ of\ sandwiches}$

⇒ $x=\frac{8.3}{5}$

⇒ $x =1.66$ Ounces

So each sandwich will get 1.66 ounces of peanut butter.

What number can you cube to make it bigger than 200 but smaller than 400

frosja888 [35]

If you would like to cube one number and make it bigger than 200 but smaller than 400, you can find the number using the following steps:

n ... the number
200 < n^3 < 400

For example:
If n equals to 6, then n^3 = 6^3 = 6 * 6 * 6 = 216 and 200 < 216 < 400, so the result could be 6.
If n equals to 7, then n^3 = 7^3 = 7 * 7 * 7 = 343 and 200 < 343 < 400, so the result could also be 7.
But, if n is 8, then n^3 = 8^3 = 8 * 8 * 8 = 512 and 512 > 400.

Result: You can take the numbers 6 and 7.
