1 \frac{5}{6} +2 \frac{2}{11} =\frac{(1\times6)+5}{6} +\frac{(2\times 11)+2}{11} =\frac{11}{6}+\frac{24}{11} \\\\=\frac{11\times 11}{6\times 11} +\frac{24\times6}{11\times6} =\frac{121}{66} +\frac{144}{66}=\frac{121+144}{66} =\frac{265}{66}\\\\=\boxed{\bf{4\frac{1}{66}}}

Please help answer the following question
Elena L [17]

Answer:

D

Step-by-step explanation:

The unmarked angle of the triangle is also 40o. The triangle is marked with two equal sides (isosceles).

<2 + 40 + 40 = 180            Combine the left

<2 + 80 = 180                    Subtract 80 from both sides

<2 = 180 - 80

<2 = 100 degrees.

That's not the answer. We have to solve for x

<2 = x + 106

100 = x + 106       Subtract 106 from both sides

100 - 106 = x

x = - 6

The volume of a rectangular prism is found using the formula V = l · w · h, where l is the length, w is the width, and h is the
Anastaziya [24]
There are additional details to the problem that you have left out. I have found them in other resources. The tray has to be 3 centimeters high and the length is five centimeters longer than its width. The volume of the tray is 252 cubic centimeters.

With these given, we can find the equation with the width alone as the variable:

V=lwh
252=(x+5)(x)(3)
84= x^{2} +5x

To know if it's possible for the width to be 7.5 centimeters, we just plug this as the value of x and see if it satisfies the equation:

84= (7.5)^{2} +5(7.5)
84= (7.5)^{2} +5(7.5)
84=93.75

As we can see, the equation was not satisfied therefore it is NOT possible for the width to be 7.5 centimeters.

What is 0.000000685 written in scientific notation?
maria [59]

we have

0.000000685

we know that

0.000000685=\frac{685}{1,000,000,000} =\frac{685}{10^{9}}=685*10^{-9}

685*10^{-9} =6.85*10^{-7}

therefore

<u>the answer is</u>

6.85*10^{-7}
