Answer:
615,000
Step-by-step explanation:
When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
Answer:
Fraction of the garden used = ![\frac{5}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7D)
Step-by-step explanation:
The fifth graders to plant a butterfly garden.
We are given that
Clover grows in ½ of the garden
Daisies grow in ¼ of the garden
Coneflowers grow in ⅛ of the garden
milkweed grows in ⅛ of the garden
The fifth graders notice that the butterflies land on the clover and milkweed.
We are asked to find out the fraction of the garden that the butterflies used.
Fraction of the garden used = clover + milkweed
Fraction of the garden used = ![\frac{1}{2} + \frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2B%20%5Cfrac%7B1%7D%7B8%7D)
The LCM of 2 and 8 is 8
Fraction of the garden used = ![\frac{4 +1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B4%20%2B1%7D%7B8%7D)
Fraction of the garden used = ![\frac{5}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7D)
Therefore, the butterflies used
fraction of the garden.
Step 1. Multiply first equation with -3 and the second one with 2. You'll get:
![\left \{ {{-9x-6y=-12} \atop {8x+6y=14}} \right.](https://tex.z-dn.net/?f=%20%5Cleft%20%5C%7B%20%7B%7B-9x-6y%3D-12%7D%20%5Catop%20%7B8x%2B6y%3D14%7D%7D%20%5Cright.%20)
Step 2. Add both equations together. You'll get:
![-x=2](https://tex.z-dn.net/?f=-x%3D2)
, which gives x = -2
Step 3. Replace x = -2 in the first equation and calculate y.
![3(-2)+2y=4\\ y=\frac{4+6}{2}=5](https://tex.z-dn.net/?f=3%28-2%29%2B2y%3D4%5C%5C%0Ay%3D%5Cfrac%7B4%2B6%7D%7B2%7D%3D5)
The solution is: x=-2, y=5
N/4.3 = 9.4
4.3 × n/4 = 9.4 × 4.3
n = 40.42
