Answer: The answer would be 8.5 times 10^-5
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.

Answer:
d) The possible value of n can be expressed as 15 < n < 25.
Step-by-step explanation:
Here, the given sides of the triangle are:
First Side = 20 cm
Second Side = 5 cm
Third side = n cm
Now ,as we know " SUM OF ANY TWO SIDES OF A TRIANGLE IS ALWAYS GREATER THAN THE THIRD SIDE"
⇒ Length of ( First + Second ) side > Third Side
or,( 20 cm + 5 cm ) > n cm
or, n < 25 cm
Now, from all given options,
15 < n < 25 is the MOST APPROPRIATE.
Hence, the possible value of n can be expressed as 15 < n < 25.
x = number of weeks which is some positive whole number
50x = amount saved after x weeks, when saving $50 per week
50x+800 = add on the 800 she already has
The expression 50x+800 is the total money saved. We set this equal to the 1150 to set up the equation we're after
<h3>Answer: 50x+800 = 1150</h3>
