1. Ana was washing dishes at the end of her shift at a restaurant. She washed 30 plates from 7:30 to 7:35. When she finishes was

irga5000 [103]

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

Question 6 Multiple Choice Worth 1 points)

slavikrds [6]

Answer:

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

$17 -(-3) = 20.$

Step-by-step explanation:

We are given the following expression in the question:

$17 - (-3)$

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

$x + (-x) = 0$

Additive Inverse of -3 is 3

$-3 + (3) = -3+3 = 0$

Option B) correctly explains the given statement.

$17-(-3) = 17+3 = 20$

Opion B)

The additive inverse of -3 is +3, so

$17 -(-3) = 20.$

A differentiable function f has the property that f(5)=3 and fprime(5)=4. What is the estimate for f(4.8) using the local linear

icang [17]

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

a state issues car license plates with three letters followed by three numbers (for example, fgh831 or bbb222). how many differe

vova2212 [387]

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 $26^{3}$ ways.

And 10 numbers ( 0 to 9 ) can take 3 positions with repetition in $10^{3}$ ways.

So the total number of license plates that can be made = $26^{3}$ $\times$ $10^{3}$ = 17576 $\times$ 1000 = 17576000 plates.
