B.
Answer:
11/50
Step-by-step explanation:
There are 22 3's, and 100 tries, so the experimental probability is 22/100 or 11/50.
I'm pretty sure this is Triangle stuff, with Sin, Cos + Tan, etc.
I can't remember it all I'm afraid, but the angle will be the 1 degree, 10 minutes - the Hypotenuse side will be the 3.5 km
13 cm (approximately)
Step-by-step explanation:
Let the radius of the circle be 'r'.
Area of the circle = πr²
=> 132.7 = (22/7) r²
=> 6.5 ≈ r
Therefore, diameter = 2radius = 2(6.5) = 13 cm
so for question 2 find the area of the rectangle first:

then you find the area of the triangles:


Add up all the answers:

and for question 3, part A, you just find the area of the 2 boxes and multiply:



so the surface area of the box is 90 square inches therefore the paint covered 90 square inches. For part B, just add up the length of the thick black lines:

How these helped have a good day
