ΔABO is a right triangle with AB⊥BO. The radius of the circle is BO. The Pythagorean theorem applies.
AO² = AB² + BO²
13² = 5² + r²
169 -25 = r²
r = √144 = 12
The radius (r) is 12.
Answer:
To find the value of y, you need to isolate the variable. To do this, add 21 to -12. This gives you 9. Now, you're equation is set as 9 = y. This means that the value of y is 9.
Step-by-step explanation:
I know, you have to divide 90 by what ever the length is, then you have to figure out where the points are. So it should be.... D!!!
Hello there :))
Your answer would be 1802790 people and round that... (u round)
1. take 1821000 and multiply that by .2% that will give you 3642
2. 5 years would be 5 times 3642, to find how many people being decreased. that will give you 18210
3. take your beginning total 1821000 and subtract it by 18210, and you get 1802790 people.
4. DONT FORGET TO ROUND IT. (I'm not rounding)
Answer:
7)x=20 8)x=19
Step-by-step explanation:
7)4x-40=2x
4x-2x=40
2x=40
x=20
8)
2x+19=3x
3x-2x=19
x=19
