Step-by-step explanation:

(a)

2 \frac{1}{2}\div \frac{5}{2}=\dfrac{\frac{2\times2+1}{2}}{\frac{5}{2}}\\\Rightrrow\dfrac{\frac{5}{2}}{\frac{5}{2}}=1

(b)

3\div \frac{2}{3}=\dfrac{3}{\frac{2}{3}}=\frac{3\times3}{2}=\frac{9}{2}

(c)

6 \frac{3}{4}\div 2\frac{1}{4}=\dfrac{\frac{6\times4+3}{4}}{\frac{2\times4+1}{4}}\\\Rightarrow \dfrac{\frac{27}{4}}{\frac{9}{4}}=\frac{27}{9}=3

(d)

\frac{1}{3}\div 3=\dfrac{\frac{1}{3}}{3}=\frac{1}{9}

SVETLANKA909090 [29]

Answer:

E=2.8 m-40

Step-by-step explanation:

We konw that  30°E=25°M and 310°E=125°M

so if we want to write an ecuation that linearly relates E with M, we can use the formula of the line that crosses two points:

Y-y1= (y2-y1)/(x2-x1)*(X-x1)

In thts case:

  • Y=E
  • y1= E1= 30
  • y2= E2=310
  • x1= M1= 25
  • x2=M2=125

so

E-E1= (E2-E1)/(M2-M1)* (M-M1)

E-30 = (310-30)/(125-25)*(M-25)

E-30 =280/100 *(M-25)

E-30 =2.8 M- 280*25/100

E-30 =2.8 M-70

E= 2.8 M-70+30

E=2.8 M-40

Good luck!

The perimeter of a square is equal to the perimeter of an equilateral triangle. The length of a side of the square is given by x
mars1129 [50]

We can use the equation x=\frac{3}{4} y to find the length of the side of a square.

<u>Solution:</u>

Given that, the perimeter of a square is equal to the perimeter of an equilateral triangle.  

The length of a side of the square is given by "x"

And the length of a side of the equilateral triangle is given by "y"

Finding the equation to determine value of "x"

<em><u>The perimeter of a square with side "x" is given as:</u></em>

\text { perimeter of a square }=4 \times \text { side }=4 x

<em><u>Perimeter of a equilateral triangle with side "y" is given as:</u></em>

\text { perimeter of a equilateral triangle }=3 \text { side }=3 y

Given that perimeter of a square = perimeter of an equilateral triangle

\begin{array}{l}{\rightarrow 4 x=3 y} \\\\ {\rightarrow x=\frac{3}{4} y}\end{array}

Hence, we can use the equation x=\frac{3}{4} y to find the length of the side of a square.
