12.5 (area of triangle) +40 (area of rectangle)=52.5
Answer:
5
Step-by-step explanation:
I am not quite sure if this is correct.
first I figured out how many minutes per 1 mile: 24
then I figured out how exactly much time 1.5 hours is: 1 hour and 12 minutes. then I subtracted that from 2 hours, knowing that 1.5 hours is 3 miles, I found that there was only 48 minutes remaining in that hour, which would be 24×2, aka 2 miles. so the final answer would be 5 miles, sorry for the run-on sentence. Yet again, I am not quite sure if this is right-

Answer:
1/7
Step-by-step explanation:
The list of numbers generated is; 0, 1, 2, 3, 4, 5, 6,
There are 7 possible outcomes and each outcome is equally likely. The probability or chance that each number will occur is given by;
number of times the number occurs / 7
In our case, each number occurs only once, so the chance will be;
1/7

Step 1) get r from area= pi *r^2
2) found the centimeters
Answer:
b=20 or b=-20
Step-by-step explanation:
Keep in mind the meanings of the values of the discriminant:
If b^2-4ac=0, then the quadratic will have only 1 solution (double root)
If b^2-4ac<0, then the quadratic will have no real solutions
If b^2-4ac>0, then the quadratic will have 2 unique solutions
In this case, to get one real solution, the discriminant must be set up as b^2-4ac=0. Setting up the equation we get:
b^2-4(4)(25)=0
b^2-400=0
b^2=400
b=20 or b=-20
So the values of b would have to be either 20 or -20
