omar has 5 liters of water he divides the water evenly between 4 buckets. how many milliters does omar pour in each bucket

ArbitrLikvidat [17]

Answer:

1250 milliliters

Step-by-step explanation:

Omar has 5 liters of water. He divides evenly between 4 buckets.

5/4 = 1.25

He pours 1.25 liters in each bucket.

Convert 1.25 liters into milliters.

1.25 × 1000

1250 milliliters.

Omar pours 1250 milliliters in each bucket.

Please help with 6!!!! Find the value of X if necessary, round your answer to the nearest 10th figure is not drawn to scale

Andrews [41]

So uh i answered the question already but in case it didn't post i will paste my answer here too:
16.9if FG is 20, and RS is 24, and they are both in the same circle and are both (t-shaped ya know like it says--I don't know what to call them), then its a ratio:FG20/OP14 is the same as RS24/x;24*14= 336/20= approximately 16.9

An article gave the following summary information for fracture strengths (MPa) of n = 196 ceramic bars fired in a particular kil

Oliga [24]

Answer:

54.80 MPa to 55.92 MPa

Step-by-step explanation:

Sample mean fracture strength (x) = 55.36 MPa

Sample standard deviation (s) = 3.99 MPa

Sample size (n) = 196.

The upper and lower bounds for a 95% confidence interval are given by:

$U=x+1.960*\frac{s}{\sqrt{n}} \\L=x-1.960*\frac{s}{\sqrt{n}}$

The upper and lower bounds of the confidence interval are;

$U=55.36+1.960*\frac{3.99}{\sqrt{196}}\\U= 55.92\\L=55.36-1.960*\frac{3.99}{\sqrt{196}}\\L= 54.80\\$

The 95% confidence interval for true average fracture strength is 54.80 MPa to 55.92 MPa

I just need the extraneous root

gregori [183]

Answer:

Step-by-step explanation:

$2+\sqrt{2x-3} =\sqrt{x+7} ~~~(1)\\ x \ge -7\\and ~x\ge \frac{3}{2} \\squaring ~(1)\\4+2x-3+4\sqrt{2x-3} =x+7\\4\sqrt{2x-3} =x+7-2x-4+3\\4\sqrt{2x-1} =-x+6\\squaring\\16(2x-3)=x^2-12x+36\\32x-48=x^2-12x+36\\x^2-12x-32x+36+48=0\\x^2-44x+84=0\\\\x^2-2x-42x+84=0\\x(x-2)-42(x-2)=0\\(x-2)(x-42)=0\\x=2,42\\x=2 is a solution.\\whereas ~x=42 ~is~an~extraneous ~root.\\as~2+\sqrt{2*42-3} =\sqrt{42+7} \\2+\sqrt{81} =\sqrt{49} \\2+9=7\\or 11=7\\which~is~not~true.$
