Please help? I’m really confused

48.2 in^3

Step-by-step explanation:

It'd be easier to calculate the volume if you'd change the mixed numbers to mixed numers with decimal fractions:

2 1/2 becomes 2.5

3 2/3 becomes 3.67

5 1/4 becomes 5.25

Then V = L*W*H, or

V = (5.25 in)(3.67 in)(2.5 in) = 48.2 in^3

answer: i would say b

step-by-step explanation:

with the way the question is worded, i believe b is the answer

the cost of the apple depends on the weight

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
