Answer:
7a+7b+17
Step-by-step explanation:
Just add them all.
150 deer because if they killed or tagged 30 then it would be 180-30=150
1) x^2=64 is the same as x=the root of 64 which gives us: (+-)8
2) here you must us pq-formel as:
5m^2-5m=60
5m^2-5m-60=0
(m^2-5m-60)/5=0
m^2-m-12=0
m=0,5(+-) the root of 0,25+12
m=0,5(+-)3,5
m1=0,5+3,5
m2=0,5-3,5
15) x^2=7x
x^2-7x=0 here there is two x, so:
x(x-7)=0
x1=0
x2=7

Here you can only use PQ formula in all the others, just as I did in the question number 2</span>
Answer:
, which is approximately 
.
Step-by-step explanation:
In a given circle, the angle of a sector is proportional to the length of the corresponding arc:
.
For the circle in this question, 
, and the circumference would be:
.
The full circle itself is like a sector with an angle of 
, with the arc length equal to the circumference of the circle.
.
.
Rearrange the equation to find the angle of the sector:
.
In other words, the angle of this sector would be 
. Multiply that measure in radians by 
to find the value of the angle measured in degrees:
.
