The answer is 60 feet.
Step by step explanation:
The area of a triangle is Area= base x height divided by 2.
Solve for the base:
Base= 2* area/ height and plug in the data:
Base= 2* 600/20
Final answer:
Base: 60 feet.
Its the first one because everytime you rotate the shape it will stay within the lines
Answer:
103.62 cm squared :)
Step-by-step explanation:
To solve this problem, lets start with the grey area only and essentially we want to treat it like it's own circle. So the formula for circular area is A=pi times r²
so for the radius of the grey region, we will simply add 3 and 4 cm.
3+4=7cm
Then we can plug that into the area equation, which is:
A = (3.14)(7²)
Solve for that and we should get 153.86 cm²
We'll hold onto that for now while we solve for the white circle next:
A = (3.14) (4²)
A = 50.24cm²
Lastly, let's bring back the grey area we found earlier, and subtract the white area from it:
153.86 - 50.24 = 103.62 cm²
hope this helps and good luck~
Sorry I don't really understand the question but
If you are looking for r in terms of w:
3w - 6r = 30
-6r = 30 - 3w
r = -5 + 0.5w
r = 0.5w - 5

If you are looking for the exact value of x, sorry, I don't know..... (-_-")
Answer:
Red is 3/10
yellow is 1/3
Step-by-step explanation:
since there is 10 marbles all together it will be out of 10
and since there is 3 red marbles the probability is 3/10
but when you take out one of the marbles the total amount of marbles in the bag is 9. since there is 3 yellow marbles in the bag it would be 3/9 which can be simplified to 1/3
