Answer: r - radius of a circle
d - diagonal of a square inscribed in a circle
a - side of a square inscribed in a circle
shaded area - area of a square inscribed in a circle
The answer will basically be 9
Step-by-step explanation:
Answer:
m∠1 = 108°
m∠2 = 72°
Step-by-step explanation:
By applying triangle sum theorem in the given triangle,
Sum of all interior angles = 180°
38° + 70° + m∠2 = 180°
m∠2 = 180° - 108°
= 72°
Since, angles 1 and 2 are the linear angles,
Therefore, m∠1 + m∠2 = 180°
m∠1 + 72° = 180°
m∠1 = 180° - 72°
m∠1 = 108°
Answer:
Anything with 2 Yellow and more than 3.5 Blue
Step-by-step explanation:
The answer is pretty obvious, but I will give a more mathimatical explanation that is easy to understand. The ratio is saying that for every 2 units of yellow, there are 3.5 units of blue. You can find ratios that are the same but use more/ less amounts. So if you use 4 units of yellow and 7 of blue it is the same ratio.
If you multiply both parts of the ratio (or divide) by the same number you will always get the same ratio. So if you want something more blue (or yellow) you just have to keep one the same while increasing the one you want to have more effect.
Answer:
i do believe its 12
Step-by-step explanation:
You need to add one equation to the other. To do this, multiply the divide the entire equation by 2. The resulting equation gives: -6x + 3y = 9
Now, add this to the second. Doing this will cancel out the 6xs because they are opposite signs.
-4y = 4 is your simplified equation.
Solve for y: y = -1
Plug this into an original equation.
-12x + 6(-1) = 18
-12x -6 = 18
-12x = 24
x = -2
