Answer:

x = 106°

y = 127°

Step-by-step explanation:

x = 2* 53° = 106°

(Measure of the angle subtended on the center of the circle is twice the measure of inscribed angle)

y = 1/2 ( 360° - 106°)

(By inscribed angle theorem)

y = 1/2 *254°

y = 127°

-2 1/2 / 6 would be -5/12, just turn - 2 1/2 into a decimal and divide by 6 :)

A body builder consumed 5,600 calories yesterday. Today, he consumed 4,200 calories.

hammer [34]

well, the difference from 5600 to 4200 is 1400.

If we take 5600 to be the 100%, how much is 1400 off of it in percentage?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} 5600&100\\ 1400&x \end{array}\implies \cfrac{5600}{1400}=\cfrac{100}{x}\implies 4=\cfrac{100}{x} \\\\\\ 4x=100\implies x=\cfrac{100}{4}\implies x=25$

Some students are working together to draw a picture of a playground.

vodomira [7]

From the information provided by the statement, you know that

*Ann draws 2/16 of the playground

*Susan draws 6/16 of the playground because she draws 3 times as much as Ann so

$3\cdot\frac{2}{16}=\frac{3}{1}\cdot\frac{2}{16}=\frac{6}{16}$

*Louise draws 3/16 because she draws half as much as Susan, so

$\frac{1}{2}\cdot\frac{6}{16}=\frac{6}{32}=\frac{2\cdot3}{2\cdot16}=\frac{3}{16}$

*Sam draws 2/16 because she draws 1 less section than Louise

$\frac{3}{16}-\frac{1}{16}=\frac{2}{16}$

Now, let x be the fraction of the playground that still needs to be drawn. Then, you have

$\begin{gathered} \frac{2}{16}+\frac{6}{16}+\frac{3}{16}+\frac{2}{16}+x=\frac{16}{16} \\ \text{ Add similar terms} \\ \frac{13}{16}+x=\frac{16}{16} \\ \text{ Subtract }\frac{13}{16}\text{from both sides of the equation} \\ \frac{13}{16}-\frac{13}{16}+x=\frac{16}{16}-\frac{13}{16} \\ x=\frac{3}{16} \end{gathered}$

Therefore, 3/16 of the playground still needs to be drawn.
