Answer:
Hi!
The correct answer is d) 1 over 15 minus 1 over x equals x over 35.
Step-by-step explanation:
We know the amount of time that Byron can fill a drying rack with dishes: 15 minutes.
We know the amount of time that Byron can fill a drying rack with dishes while Emmitt is taking dishes out of the drying rack: 35 minutes.
We don't know the amount of time that Emmitt can take dishes out of the drying rack: x minutes.
So, if Byron is filling the drying rack in 15 minutes and Emmitt is taking out the dishes at x minutes, it takes 35 minutes to fill the drying rack.
<em>// multiply by 105x both sides.</em>
<em>// simplifly</em>
<em> //substract 3x and add 105 in both sides</em>
<em>// solve</em>
<em>//</em> <em>divide by 4 in both sides</em>
<em>// solve</em>
It makes sense that Byron fills the rack faster than Emmitt empties the rack.
Since you have not presented any choices wherein we can determine the best answer, I will go on and share my thoughts on how she could improve the results of her survey.
Since she just surveyed her ballet class, she should opt for surveying on other classes with other genres. This would entail reliability and validity and eliminate bias about the results.
Answer:
4800
Step-by-step explanation:
In 10 seconds his wings will flap 800 times!
So in 60 seconds his wings will go 6 times more frequently.
10 /800 = 60/x
10 x = 800 * 60
10 x = 48000
x = 48000/10
x = 4800
Answer:
D. g(x) = -x² - 3
Step-by-step explanation:
The g(x) is in the opposite side of f(x). So it is negative.
-x²
The y-intercept is (0, -3).
g(x) = -x² - 3
Y=-3x+7
