How does knowing 1/5 of 10 help you find 3/5 of 10? Draw a picture to explain your thinking.

Alborosie

Answer:

If the problem is,

$\frac{1}{5}\text{ of }10$

By finding it,

Take a 5 box grid in which each box represents 1 unit,

Then take 1 box of this grid,

Repeat this step,

Finally, Add them,

We get,

A grid having 10 boxes with 2 taken boxes,

Thus, $\frac{1}{5}\times 10=2$

When we do these steps for three grids we will get $\frac{3}{5}\times 10$ ,

That is, by multiplying the result of $\frac{1}{5}\times 10$ by 3 we will obtain $\frac{3}{5}\times 10$

$\frac{3}{5}\times 10=3\times (\frac{1}{5}\times 10)=3\times 2=6$

a vehicle factory manufactures cars. The unit cost C (the cost in dollars to make each car) depends on the number of cars made.

timofeeve [1]

Answer:

8,567

Step-by-step explanation:

Given the cost function expressed as C(x)=0.7x^2- 462 x + 84,797

To get the minimum vaklue of the function, we need to get the value of x first.

At minimum value, x = -b/2a

From the equation, a = 0.7 and b = -462

x = -(-462)/2(0.7)

x = 462/1.4

x = 330

To get the minimum cost function, we will substitute x = 330 into the function C(x)

C(x)=0.7x^2- 462 x + 84,797

C(330)=0.7(330)^2- 462 (330)+ 84,797

C(330)= 76230- 152460+ 84,797

C(330) = 8,567

Hence the minimum unit cost is 8,567
