The standard quantity of metal per ring is 0.57 kilograms.
Step-by-step explanation:
Each ring requires 0.52 kilograms of a special metal.
The allowance for waste is 0.03 kilograms per ring, while the allowance for rejects is 0.02 kilograms per ring.
So, the standard quantity of metal per ring = 0.52 kg of metal required + 0.03 kg of allowance for waste + 0.02 kg of allowance for rejects)
= 
kilograms.
Hence, the standard quantity of metal per ring is 0.57 kilograms.
Answer:
x=10
Step-by-step explanation:
3x-5x+5.6=-14.4
Simplify
-2x+5.6=-14.4
Subtract 5.6 from both sides
-2x=-20
Divide both sides by -2
x=10
Answer:
-6,-8
Step-by-step explanation:
Theory:
Time flies by, there isn't an exact number at one time. Look it up online, and 131 could only mean the confirmed deaths, not the actual amount.
Domain asks for any restrictions on the x-value and the range asks for any restrictions on the y-value.
Let's tackle this one at a time.
Domain: We're dealing with a quadratic function or a parabola, so usually there wouldn't be any restrictions on the x-value. When you graph out this parabola, you can see that the x-values will continue to grow to infinite and negative infinite.
Hence, there are no restrictions for the domain, and it would be all real values.
Range: Now, based on the graph, there is definitely a point at where the graph doesn't exist anymore. For a concave up or down, the range would always be greater or less than the x-value of the vertex. In this case, we have a concave up parabola, and as such, we would have a y-value that exists for when y ≥ -3
