Answer:
BZ = 64/23 = 2 18/23
Step-by-step explanation:
The angle bisectors divide the triangle into proportional parts, so we have ...
CB/CY = AB/AY
CB = CY(AB/AY) = 4(8/6) = 16/3 . . . . multiply by CY and evaluate
and ...
BZ/CB = AZ/AC
BZ = AZ(CB/AC) . . . . multiply by CB
But we have ...
AZ = 8 -BZ, so this becomes ...
BZ = (8 -BZ)(16/3)/(10)
BZ(1 +8/15) = 64/15 . . . . add the BZ term on the right to both sides
BZ = (64/15)(15/23) = 64/23 . . . . divide by the coefficient of BZ
BZ = 64/23 = 2 18/23
Answer:
30.39in^2 (^2 means squared)
Step-by-step explanation:
3 x 3 = 9in^2
3.1 x 6.9 =21.39in^2
9 + 21.39 = 30.39in^2
Answer
y = 2x
Explanation
The first thing is to find the gradient of the line.
Gradient = Δy/Δx
= (4--2)/(2--1)
= 6/3
= 2
Now a general point (x, y) and one of thegiven points.
(y - 4)/(x - 2) = 2
y - 4 = 2(x - 2)
y = 2x - 4 + 4
y = 2x + 0
y = 2x
N=(3/4)*h*d
--------------------
n=Number of hours she reads
h=Hour(s)
d=Days
--------------------
You see, with this formula - when d=2,
n=(3/4)*h*2=(6/4)*h=(3/2)*h=1.5 hours
So, in the space of 2 days, she had spent 1.5 hours reading.
(9)(3) + 5
27 + 5
32
Your answer is 32.
