Answer:

-3/2

Step-by-step explanation:

In the picture attached, the complete question is shown.

The expression is:

\frac{ \frac{1}{2} }{ \frac{-2}{5}} + \frac{-1}{4}

You can rewrite the first term, expressing the division as a multiplication, that is, inverting the fraction in the denominator, as follows:

\frac{1}{2} \times \frac{-5}{2}+ \frac{-1}{4}

\frac{-5}{4} + \frac{-1}{4}

The addition of a negative fraction is simply the subtraction by that fraction:

\frac{-5}{4} - \frac{1}{4}

\frac{-5 - 1}{4}

\frac{-6}{4}

Which can be simplified dividing by two both numerator and denominator:

\frac{-3}{2}

Answer:

x = 14.375

Step-by-step explanation:

Ok, so we know that a triangle has a total interior degree of 180°. And since we already have a 95° angle, we just need to subtract 95 from 180.

180° - 95° = 85°

Now, we already have indicators that two of the three sides are equal. And we already got the angle of the side that does not have a matching partner. So we just need to divide what we already have by 2.

85° / 2 = 42.5°

Now that we know each side is 42.5 degrees, we just need to grab our given equation and put and equal sign at the end with what we already know is the answer (since we are trying to solve for <em>x</em>).

(4x - 15) = 42.5

Now, let's just get rid of those useless parentheses.

4x - 15 = 42.5

Next, we just need to have the variable on its own side, all by itself. So, in order to do that, we just add 15 to both sides.

4x = 57.5

Now, for our final step, we just need to divide each side by our variables' factor (which is a positive 4). In which we get our final answer of:

x = 14.375

Please help me!!!!!!!!!!!!!!!
Ainat [17]

r = 7.53 so d = 2r = 2(7.53) = 15.06 cm

Area of square = d^2 / 2 = (15.06)^2 / 2 = 113.41 cm^2

Area of circle = 3.14 (7.53)^2 = 178.04 cm^2

Area of yellow region = Area of circle - Area of square

Area of yellow region = 178.04 cm^2 - 113.41 cm^2

Area of yellow region =64.63 cm^2 = 64.6 cm^2 (nearest tenth)

Answer

64.6 cm^2
