First one is c and second one is 6.2 x 10^1
R = 3S
R + 6 = 2 (S+6)
Substitute the first equation in the second one:
(3S) + 6 = 2 (S + 6)
3S + 6 = 2S + 12
S + 6 = 12
<u>R = 18
</u>S = 6<u>
</u>
Check:
R is 3 times S now.
In 6 years, R will be (18 + 6) = 24, S will be (6 + 6) = 12.
24 = 2 x 12 yay
16s2tu^3v^3 is the answer
Answer:
52 ft
Step-by-step explanation:
For each chord, the product of segment lengths is a constant. We can find that constant as the product of the segment lengths of the bisected chord:
(24 ft)·(24 ft) = 576 ft^2
Then the missing segment length (DX) of the diameter chord is ...
DX·(36 ft) = 576 ft^2
DX = (576 ft^2)/(36 ft) = 16 ft
So, the total length of the diameter chord is ...
DX +XL = 16 ft + 36 ft
DL = 52 ft
_____
We know DL is a diameter because the perpendicular bisector of any chord intersects the center of the circle.
Answer:
51
Step-by-step explanation:
since 1 = 39 degrees, it'd be complementary if you were to open it up if it were a C, it would be 90. So since its this way, i believe you would take 39 and do 90 - 39 to get your answer. Im sorry if this is wrong but i hope it helps you!!
