Answer:
Step-by-step explanation:
The interior angles of a triangle must add to 180 degrees.
Let's add the three angles we are given and see what the sum is.
- The three angles are 127, 38, and 15
Add them together.
- 127+38+15=180
- 3 angles = 180 degrees
The three angles equal 180 degrees, therefore they can create a triangle.
First, subtract 0.6 from both sides of the numbers and then simplify
Then multiply all terms by the same value to eliminate fraction denominators which gives us 2.8
So, n = 2.8

Answer:
Step-by-step explanation:The surface area of a sphere (the shape of a baseball) is given by the formula, SA = 4 (pi) r^2. Given the circumference of the circle, you can solve for the radius.
The formula for circumference is C = 2 x pi x r.
So input 9 for C and solve. 9 = 2 x pi x r.
You will get that r is equal to about 1.43 in.
Now put that r value into the surface area equation: SA = 4 (pi) 1.43^2
You will get a surface area equal to about 25.7 in^2.
Now multiply that number by the number of baseballs you need to cover, 100.
I'll let you do that step by yourself since it's simple algebra and you're smart enough to figure it out ;)
