Test the nature of the roots by evaluating the discriminant b^2 - 4ac:

Discriminant = 1^2 - 4 * 1 * 1  = -3

This is negative so there are no real roots of this equation

Square root of  3 is irrational 

So its F T --> F

Crane Company recently billed a customer $ 720. Labor hours were 6 and the cost of the materials used was $ 150. If the company’

The materials were charged at a loading charge of 80.00% of their cost.

The total charge was $720 and included both the material charge and the labor charge.

The first thing to do is therefore find out the cost of the materials without the labor charge:

<em>= Total cost - labor charge</em>

= 720 - (6 labor hours x 75 per labor hour)

= 720 - 450

= $270

The total cost of materials is $270. To find the material loading charge, use the formula:

<em>= (Total cost of materials - Cost of materials used) / Cost of materials used x 100%</em>

= (270 - 150) / 150 x 100%

= 120 / 150 x 100%

= 80%

In conclusion, the material loading charge was 80.00%.

-25 Points-
kicyunya [14]

Answer:

1/6

Step-by-step explanation:

the probability of the red die shows a number larger than 3 (P1) = 3/6 = 1/2

the probability of the green die shows a number less than 3 (P2) = 2/6 = 1/3

the probability of both happening = P1 * P2 = (1/2) * (1/3) = 1/6

Help me graph these linear programs
Ulleksa [173]
Change all of the equations to standard form, then place the number without the variable (y-intercept) on the correct spot on the graph for example the number 6 would be graphed on the top (positive) y-axis. Then when your finished doing that place the number with the variable or just the individual variable as a slope form (rise over run) on the graph, ex: if your slope was 4x you would rise 4 then move to the right 1 bc its 4/1. Your all set.
