Step-by-step explanation:
if one pump = x
the other pump = 2x
therefore
x + 2x = 8 minutes
3x = 8 minutes
Divide through by 3
x = 8/3 minutes
converting it to seconds
x = 8/3 * 60
x = 160 seconds
therefore
the first pump = 2x = 2 * 160 = 320 seconds
the second pump = x = 160 seconds
Its B because is a situation where we note the rate at which the number of population was changing before the study
Answer:
The distance is 9
Step-by-step explanation:
Distance formula:
Plug in the points:
Your initial instinct would be to solve this problem with this solution. 34 x 57 = 1,938 petals.
However, the word estimate is present; therefore, we have to consider that we need to get the approximate number and not the exact number of petals.
There is a general rule regarding estimation or approximation. You have to round it to the nearest place you have based on. In this problem we round it off to the nearest tens place.
If the number is below 5, you round it down: 34 is rounded down to 30 petals.
If the number is above 5, you round it up: 57 is rounded up to 60 sunflowers.
Thus, your equation would be : 30 x 60 = 1,800 petals (best estimate)
Answer:
The Answer is A. 8
Explanation:
<em>For Answer Choice A: </em>
There's nothing to explain here. It's just the number 8.
<em>For Answer Choice B: </em>
2 · 2 · 2 · 2 is 16. That symbol ( · ) is another way of writing the multiplication symbol. So this problem is essentially 2 x 2 x 2 x 2, which equals 16.
<em>For Answer Choice C: </em>
Well, this one needs no explanation either. It's just the number 16.
<em>For Answer Choice D: </em>
<em /> is also equal to 16. I'm too lazy to explain how to do this one so yea.
Hope this helps you. Uh, yea. Have a good day? omg I'm so tired
