Multiply the following numbers. reduce the answer to lowest terms. 3 1/5 . 2 1/7

48/7

Step-by-step explanation:

3 1/5 . 2 1/7

= 16/5 * 15/7

= 16/1 * 3/7

= 48/7

6 30/35

Step-by-step explanation:

3 1/5 × 2 1/7

convert from mixed fraction to proper or improper fraction

16/5 × 15/7

now, multiply numerator to numerator, denominator to denominator.

16 × 15 / 5×7

240/35

6  30/35

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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
