9:45 plus 3 hours goes to 12:45 pm. add 45 minutes you get 1:30PM as your answet
You would need to find the circumference(using the formula c=3.14r^2) of the tree which is 113.04 then you would have to divide it by 6 which is 18.84 which would round up to 19
Answer: 19 people
<h3>Answer:</h3>
64
<h3>Explanation:</h3>
6+4= 10
Then reverse the digits of 64, and you have 46
64-46= 18
So you will need to solve for x and y before evaluating 2x+y....
2x-y=9, y=2x-9 now this will make 4x^2-y^2=171 become:
4x^2-(2x-9)^2=171
4x^2-(4x^2-36x+81)=171
36x-81=171
36x=252
x=7, now we can use 2x-y=9 to solve for y...
2(7)-y=9
14-y=9
-y=-5
y=5
now we know that x=7 and y=5, 2x+y becomes:
2(7)+5
14+5
19
Speed=distance/time
You'll have to combine like terms.
36+14=50
1.5+0.75=2.25
And then you can use the formula.
50/2.25
