Answer:

  1. d = 2/3
  2. c = 3/2
  3. y = 2/3
  4. x = 4 2/19

Step-by-step explanation:

<u>Solving for variables</u>

1.......................................

  • 4 2/9 =6 1/3∙d
  • 38/9= 19/3d
  • d = 38/9 ÷ 19/3
  • d = 38/9*3/19
  • d = 2/3

2.......................................

  • c÷ 2/11 =8 1/4
  • c ÷ 2/11 = 33/4
  • c = 33/4*2/11
  • c = 3/2

3.......................................

  • 2 1/2 =1 2/3÷y
  • 5/2 = 5/3 ÷ y
  • y = 5/3 ÷ 5/2
  • y = 5/3 * 2/5
  • y = 2/3

4.......................................

  • 6x=24 12/19
  • 6x = 24 + 12/19
  • x = 24/6 + 12/19 *1/6
  • x = 4 + 2/19
  • x = 4 2/19

3/7 of 8th graders play sports. is 3/5 of the 8th graders that play sports are boys, what fraction of the 8th graders are boys
Svetach [21]

Answer:

\dfrac{9}{35} is the fraction of 8th graders who are boys.

Step-by-step explanation:

Let total number of 8th graders = x

Given that, \frac{3}{7} of 8th graders play sports

\Rightarrow 8th graders who play sports = \frac{3}{7} \times x

Also, Given that, \frac{3}{5} of 8th graders that play sports are boys

Number of 8th graders that play sports, and are boys = \frac{3}{5} \times \text{Number of 8th graders who play sports}

\Rightarrow \dfrac{3}{5} \times \dfrac{3}{7} \times x\\\Rightarrow \dfrac{9}{35} \times x

Hence, the answer is:

\dfrac{9}{35} is the fraction of 8th graders who are boys.

Trig: A sector of a circle has area 25 cm2 and centralangle
Alchen [17]

Answer:  Radius = 10 cm and Arc length = 5 cm

Step-by-step explanation:

The area of a sector with radius r and central angle \theta (In radian) is given by :-

A=\dfrac{1}{2}r^2\theta

Given : A sector of a circle has area 25 cm^2 and central angle  0.5 radians.

Let r be the radius , then we have

25=\dfrac{1}{2}r^2(0.5)\\\\\Rightarrow\ r^2=\dfrac{2\times25}{0.5}\\\\\Rightarrow\ r^2=\dfrac{50}{0.5}=100\\\\\Rightarrow\ r=\sqrt{100}=10\ cm

Thus, radius = 10 cm

The length of arc is given by :-

l=r\theta=10\times0.5=5\ cm

Hence, the length of the arc = 5 cm
