Answer:
EK = 8
Step-by-step explanation:
Intersecting Chords Formula: a • b = c • d
BK * KD = EK * KC
4 * 10 = (x+1) * (x-2)
40 = x^2 +x-2x-2
40 = x^2 -x -2
0 = x^2 - x-2-40
0 = x^2 -x -42
Factor
0 = (x-7) (x+6)
Using the zero product property
x-7 = 0 x+6 =0
x=7 x=-6
X is not negative
x=7
EK = x+1
EK = 7+1
EK = 8
When multiplying two negative numbers the product will be positive. For example, 5*3=15 and -5*-3=15, but 5*-3=-15 likewise -5*3=-15.
Answer:
26.67 hours or 26 hours and 40 minutes.
Step-by-step explanation:
To find out how long will it take for Joe and Bill to finish building the wall together, first find their individual work rates in feet per hour:
Bill:
Joe:
Their combined work rate is:
Then, divide the total size of the wall by their work rate to find the time spent to finish it:
34+56=90 this is your answer
