the answer is 7 it always is.
<h2>
The diagonal is increasing at 1.8 cm/minute.</h2>
Step-by-step explanation:
Let l be one side,w be other side and s be diagonal.
We have
s² = l² + w²
We have
l = 8 cm
w = 6 cm
s² = l² + w²
s² = 8² + 6²
s² = 100
s = 10 cm
Taking derivative with respect to time in s² = l² + w²

The diagonal is increasing at 1.8 cm/minute.
I believe that the answer is B

Answer:
1/8
Step-by-step explanation:
Answer:
72
Step-by-step explanation:
<em>Since the ratio of blue jays to robin's was 6 to 7 then if there were 84 robins how many blue jays were there.</em>
<em>6 to 7 can also be express as 6/7</em>
<em>Thus, we can set up a proportion</em>
<em>6/7 = x/84</em>
<em>Now, we have to solve for x</em>
<em>x = 72</em>
<em>Hence, if there were 84 robin there would be 72 blue jays.</em>
