25%. Draw a picture of 2 squares overlapping and then label the squares. find the area of the rectangle shape and then find the area where the squares are overlapping. the area is 600 and the shaded area is 150.
Answer:
12.5%
Step-by-step explanation:
2700x100÷2400=112.5
112.5-100=12.5
Answer:
Step-by-step explanation:
<u>AB is the diameter, therefore ACB is right angle</u>
- 2x + 5° = 90°
- 2x = 85°
- x = 42.5°
Correct option is A
Answer:
18.84 is the area of your circle
Step-by-step explanation:
you take 3 multiply it by 2 and then multiply that by 3.14.
Answer:
3 and 9
if f(x)=x^2+13 and g(x)=12x-14
Step-by-step explanation:
So when we are looking for the intersection of two functions, we are trying to figure out when they are the same. When you think same, you should think equal (=).
So we want to find when f(x)=g(x) for x.
f(x)=g(x)
Let's get everything to one side.
Subtracting 12x and adding 14 to both sides.
I'm going to reorder the left hand side and also simplify the 13+14 part:
Now since the coefficent of x^2 is just 1 our job is to find two numbers that multiply to be 27 and add up to be -12.
Those numbers are -3 and -9 since -3(-9)=27 and -3+(-9)=-12.
So the factored form of our equation is
Since the product is 0, then at least one of the factors must be 0.
So we want to solve both x-3=0 and x-9=0.
x-3=0 can be solved by adding 3 on both sides. This gives us x=3.
x-9=9 can be solved by adding 9 on both sides. This gives us x=9.
The intersection of f and g happens at x=3 or x=9.
