Answer:
D
Step-by-step explanation:
Approximate <em>R'</em> by using a linear approximation: for <em>x</em> close enough to 24, you have
<em>R'(x)</em> ≈ <em>L(x)</em> = <em>R' </em>(20) + <em>R''</em> (20) (<em>x</em> - 20)
Then
<em>R'</em> (24) ≈ <em>R'</em> (20) + <em>R''</em> (20) (24 - 20) = -4 + 50 (24 - 20) = 196
The width is 21 centimeters.
Fiona has 15 nickles.
In this case, it does not really matter what the objects are. We know that Ali has 3 of them and Fiona has 5 times as many, so in order to find the answer, we are going to multiply Ali's amount by 5.
Ali * 5 = Fiona
3 * 5 = Fiona
15 = Fiona
