Answer: Green route = 5.8 miles

Blue route = 5.4 miles.

Step-by-step explanation:

Let the miles travelled for Green route be x

Let the miles travelled for Blue route be y

We can form an equation from the question given which will be:

8x + 9y = 95 ........ i

12x + 6y = 102 ......... ii

Multiply equation i by 12

Multiply equation ii by 8

96x + 108y = 1140 ....... iii

96x + 48y = 816 ....... iv

Subtract iv from iii

60y = 324

y = 324/60 = 5.4

Blue route is 5.4 miles.

Since 8x + 9y = 95

= 8x + 9(5.4) = 95

8x + 48.6 = 95

8x = 95 - 48.6

8x = 46.4

x = 46.4/8 = 5.8

Green route = 5.8 miles

Lerok [7]

Convert all the numbers to real numbers:

6√3 = 10.3923

(3.5)^2 = 12.25

√75 = 8.660

9.8 = 9.8

57/5 = 11.4

A)  Now order from largest to smallest:

(3.5)^2, 57/5, 6√3, 9.8, √75

B) We found the order by solving the equations to get real numbers.

C)

Since the numbers are multiplied by a negative number, the greatest number would be the smallest number because it would be closer to zero.

The order would be the reverse of part A:

x√75, 9.8x,  6x√3, 57x/5, x(3.5)^2

D) I replaced x with -1 and calculated for real numbers. All the values were the same as A except they were the negative value.

The cost of producing hard drives has three parts: cost of materials, cost of labor, and cost of equipment. To produce x hard dr
LenKa [72]
Let x represent the number of hard drives produced.
The first thing we need to do is convert 10 cents to dollars:
10cents( \frac{1dollar}{100cents} )=0.1dollar. Now, we know that the the cost of materials is 30 dollars and the cost of labor is  0.1 dollars, so the total coast to produce x hard drives will be: 30+0.1=30.1x.
Now the only thing left is add t<span>he cost of equipment to complete our function:
</span>f(x)=30.1x+10000

We can conclude that the equation that could represent the cost function for making x hard drives is <span>f(x)=30.1x+10,000</span>
