90 books would be left I believe I just took 250/9 since it would take 9 quarters to make $2.50 and since 75% was gone that would mean 25% is left so your answer is 90 unless it’s not but I believe it’s right.
Answer:
(8.75, 2.5)
Step-by-step explanation:
When they ask what point (n,a) corresponds to this, they want a coordinate with an x-value of 8.75.
If we look on the graph, we can see that the a value is around 2.5 quarts of strawberries, so for our point, we will write (8.75, 2.5)
Answer:
a*(20-a)
Step-by-step explanation:
Let's assume that the length of the garden is a the width is b and the area is s.
b = 40/2 - a = 20-a
s =a*(20-a)=-a^2+20a=-(a-10)^2+100
then,
when a=10, max(-(a-10)^2) =0, max(s)=100
I got m 7/3 I think that's the answer
