The ratio of the circumference what is 2pir so for A. is right circumference and for B. is right diameter what is 2r because the ratio of circumference and diameter is equal 2pi*r/2r = pi so 3,14
so C/D = 2pir/2r = pi so 3,14
hope this will help you
It is 2x and 4y, so you need to use pythagorean theorem. 2 squared is 4, and 4 squared is 16. Add them, and you get 20. The problem is that that won't square to a whole number, so the closest I can get it is the square root of 20, or 2 root 4.
Answer:
Infinitely many solutions
Step-by-step explanation:
When the solved system has the same number on each side, the system has infinite solutions.
Answer:
Kevin can drive 681 miles.
Step-by-step explanation:
In order to find the amount that he can drive in one day and only pay $250, we have to write an equation for the cost. Using x as the miles he drive, we can express the equation as:
y = .33x + 24.95
Now, we can plug in 250 for y.
250 = .33x + 24.95
225.05 = .33x
681.97 = x
Since we are looking for only whole miles, we have to round down to 681.
