Answer:
explain:
you have to multiply because dilutions are a decrease so if you go from a small box to a bigger one you must multiply
Vertex is (-2,-3) and it's a minimum.
The first step is to assign the decimal number to a variable.
For the repeating fraction 0.111_1, this would look like
.. x = 0.111_1 . . . . . . . . . . where we use an underscore to identify the following digit(s) as repeating
The next step is to multiply that value by 10 to a power equal to the number of repeating digits. If there is one repeating digit (as here), then you want (10^1)x = 10x.
.. 10x = 1.111_1
The third step is to subtract x from this.
.. 10x -x = 1.111_1 -0.111_1 = 1
.. 9x = 1
And the final step is to divide by the coefficient of x.
.. x = 1/9 . . . . . . this is the value of the repeating decimal fraction.
_____
Here's one that's a little more complicated. It is done the same way.
.. x = 3.254545_45
.. 100x = 325.454545_45
.. 100x -x = 99x = 322.2
.. x = 322.2/99 = 3222/990 = 179/55
Answer: It’s C. 450.5 miles
Step-by-step explanation:
You need to first subtract 14.95 from 60. You will get 45.05. Then you have to divide by 0.1 to figure out how many miles Nichole can go. So Nichole can go 450.5 miles
Answer:
Null hypothesis: H₀: ∪ = ≤ 393 pounds
Alternative hpothesis Hₐ: ∪ > 393 pounds
Step-by-step explanation:
The null hypothesis in this case is
Null hypothesis: H₀: ∪ = ≤ 393 pounds
Agriculture Scientists wish to test against this claim believing that the new fertilizer may increase the yield, thus the alternative hypothesis will be
Alternative hpothesis Hₐ: ∪ > 393 pounds.
