A)
since she washed 30 plates in 5 mins (7:30 to 7:35) the ratio was 5:30 or in simplest form 1min:6plates
This means she washes 6 plates a min and thus from 7:15 to 7:38 (23 mins) she washes:
6X23 = 138 plates
b)
L - plates left
T- total plates
t - time(mins)
"L = T - 6x"
This is because she washes 6 plates a min

Answer:
Option B) The additive inverse of -3 is +3, so

Step-by-step explanation:
We are given the following expression in the question:

Additive Inverse:
- The additive inverse of a number a is the number when added to the original numbers it gives a sum of zero.
- Let x be a number, then additive inverse of x is -x

Additive Inverse of -3 is 3

Option B) correctly explains the given statement.

Opion B)
The additive inverse of -3 is +3, so

The linear approximation means that you assume the function is linear. So, just do :
f(5) + f'(5) (x-5)
This works out, in this specific case
3 + 4 (- 0.2)
Hope this helps
Answer:
17576000 different License plates are possible.
Step-by-step explanation:
Here we will use repetitive permutations.
First 3 digits of the license plates have letters from a to z and next 3 digits have numbers from 0 to 9.
Now, 26 letters ( a to z ) can take 3 positions with repetition in
ways.
And 10 numbers ( 0 to 9 ) can take 3 positions with repetition in
ways.
So the total number of license plates that can be made =
= 17576
1000 = 17576000 plates.
