Answer: 219.94\ cm^2

Step-by-step explanation:

Given

The central angle of a sector measures 175^{\circ}

The radius of the circle is r=12\ cm

The area of the sector is given by

\Rightarrow A=\dfrac{\theta }{360^{\circ}}\pi r^2

Insert the values

\Rightarrow A=\dfrac{175^{\circ}}{360^{\circ}}\cdot \pi \times 12^2\\\\\Rightarrow A=219.94\ cm^2

Lloyd is arranging his science project, math project, and art project on his desk. The tree diagram below shows the sample space
Margarita [4]

The tree diagram is constructed and attached below in the image.

First we have to make a choice out of 3 subjects, so the probability of choosing art as the first subject is 1/3.

Once we have chosen art as the first subject, we have two choices. So the probability of choosing each option now is 1/2. Thus, the probability of choosing math, science is 1/2.

The probability of choosing the projects in order of art, math, science = 1/3 x 1/2 = 1/6

Therefore, the probability that the projects are in order of art, math, science is 1/6 (one over 6). So first option gives the correct answer.

Write 24:14:6 in its simplest form.​
Iteru [2.4K]

Answer:

12 : 7 : 3

Step-by-step explanation:

24 : 14 : 6

12 : 7 : 3

Always start with smaller number to simplify it. Since 2 is the smaller number and it simplifies 24, 14, and 6 I start with it.

24 ÷ 2 = 12

14 ÷ 2 = 7

6 ÷ 2 = 3

We would stop here since it would not further simplify, therefore our answer is 12 : 7 : 3.

Hope this helps, thank you :) !!

I need help ASAP <br> Someone please help me questions 7&amp;8
attashe74 [19]
For #7, one line should have the y-intercept of -2 and a slope of 2/3 and the other line's y-intercept is 1 and its slope should be -5.

In the image provided, the red line represents 2/3x - 2 and the blue line represents -5x + 1.


8) Organize the information you are given.

*Savannah is 24 years older than Ryan.

So, Ryan's age + 24 = Savannah's age.

*Sebastian is 5 times as old as Ryan.
So, Ryan's age × 5 = Sebastian's age.

*Savannah and Sebastian are twins. They have the same age.
So, Savannah's age = Sebastian's age

Let x represent Ryan's age.

Write the equation based on the information you are given.

x + 24 = x(5)

x + 24 = 5x

Solution: D) 24 + x = 5x
