Answer:
The answer is D
Step-by-step explanation:
1/8 is the equivalent to 0.12
square root of 0.02 is 0.14
18% is equal to 0.18
Quadratic Formula is (-b ±√(b²-4ac))/2a
With that being said:
y=2x²-5x-1 is in the correct form of ax²+bx+c
Now just plug in:
5±√(25-4(2 x-1))
5± √25+8
(5±√33)/2(2)
Answer is D

Answer:
$42.88
Step-by-step explanation:
Let's create a proportion using the following setup:
cost/pounds=cost/pounds
We know that it costs $20.42 for a 10 pound turkey.
$20.42/10 pounds= cost/pounds
We don't know how much a 21 pound turkey costs, so we can say that it costs $x for a 21 pound turkey.
$20.42/ 10 pounds= $x/ 21 pounds
20.42/10=x/21
We want to find x, by getting x by itself.
x is being divided by 21. The inverse of division is multiplication. Multiply both sides by 21.
21*(20.42/10)=(x/21)*21
21* 20.42/10=x
21*2.042=x
42.882=x
Round to the nearest cent, or hundredth.
42.88=x
x= $42.88
A 21 pound turkey costs $42.88
Deductive reasoning is one that necessarily follows, not one that likely follows (this would be an inductive reasoning).
Here the important information is that all squares are also parallellograms, which means that they also necesarily have all the properties of the parallelogram - the correct answer is D.
Step-by-step explanation:
9.2 < 3x = 21.25
3x = 21.25 - 9.2
3x = 12.05
x = 18.2
