we have to firstly apply the distance formula to find the length of sides of the triangle
distance formula =
So length AB =
BC=
AC =
Now perimeter = AB+BC+AC =
Plug in calculator
perimeter= 11.4 units
The distance from the outside edge of a circle to its centre is given by its radius. The circumference of a circle is given by 2πr, thus if we know that this is equal to 75 feet and using π = 3.14, we get:
75 = 2*3.14*r
r = 11.942
Thus r = 12 ft (to the nearest foot)
Answer:
x=0 or x=4 or x= -5/2
Step-by-step explanation:
x²(x−4)(2x+5)=0
x²=0 or x-4=0 or 2x+5=0
x=0 or x=4 or x= -5/2
Answer:
7/12
Step-by-step explanation:
30+40+50=120
120 buttons in total
30+40=70
70 buttons that aren't white
70/120 is the probability
Simplify that to 7/12
