Answer:
18/36 or 1/2
Step-by-step explanation:
There are 18 nickels, which is the numerator.
You add all the numbers together to get the denominator, which is 12+6+18=36.
Then, you put the two values in a fraction - 18/36
and simplify, to get you 1/2.
Answer:
A , B and E.
Step-by-step explanation:
the scientist can control and deal with the measure of manure that is given to a solitary corn plants. thus A is correct.
The reaction variable is the yield recorded for each plot due to the fact that the yield recorded in each plot is needed to check whether the compost is given or not. choice B is also correct
it's considered an experiment because the specialist is controlling the autonomous variable. then E is a right choice.
X² + 6x -12 = 0
x = <u>-(6) +/- √((6)² - 4(1)(-12))</u>
2(1)
x = <u>-6 +/- √(36 + 48)</u>
2
x = <u>-6 +/- √(84)
</u> 2<u>
</u>x = <u>-6 +/- 2√(21)
</u> 2<u>
</u>x = -3 <u>+</u> √(21)
x = -3 + √(21) x = -3 - √(21)
62.4% I think Because you move the decimal over 2 places.
