Answer:
10 cm
Step-by-step explanation:
If we assume that DC is parallel to AB, then triangle DOC is similar to triangle AOB.
However, even with this assumption, there is not enough information in the diagram to solve for DO. We would also need to know the length of CO. Then we could write a proportion:
DO / (DO + 20) = CO / (CO + 24)
Edit: OD is 2 cm shorter than OC. If we call x the length of OD, then the length of OC is x+2.
Putting this into our proportion:
x / (x + 20) = (x + 2) / (x + 2 + 24)
x / (x + 20) = (x + 2) / (x + 26)
Cross multiply:
x (x + 26) = (x + 2) (x + 20)
Distribute:
x² + 26x = x² + 20x + 2x + 40
x² + 26x = x² + 22x + 40
4x = 40
x = 10
So the length of DO is 10 cm.

Answer:
9s-5g=-4u
*Isolating the S variable*
9s = -4u+5g
s = (-4u + 5g)/9
The answer is option B.
Answer:
just search it up on the internet
Step-by-step explanation:
anyways its: Russian, Finland, Estonia, Latvia, and Lithuania.
Answer: 30 mph.
Total speed = S1 + S2
where total speed is
for the average speed goal (60m ph), S1 is the speed for the first mile (30 mph)
and S2 is for speed for the second mile which is unknown. To solve, simply subtract
S1 from total speed.
<span>60 mph - 30 mph= 30 mph</span>
