Answer:
312
Step-by-step explanation:
Since the ratio is 7:8, mark it as 7x:8x.
Now, they said that the first length is 273. Solve the equation:
7x=273
x=39
Substitute it into 8x. 39*8=312. That's your answer.

Answer:
40% . The single reduction together is 40%.
Step-by-step explanation:
Let the bicycle cost is x before reduced price.
First 25% is reduced and again 20% further reduced.
Let the single reduction is y% if the two reduction together are equal.
Solution,
Case .1
reduction cost
%


The cost of bicycle after reduction of 25% is

cost of reduction further reduction of 20%
%


The new cost of bicycle is further reduction of 20% is



Case.2
if single reduction is done new cost of cycle is equal
%=



%
single reduction of a cycle is 40%
F(x)= (x-p)²+q where (p,q) is min point
f(x)=(x-1)²-2
min point is (1,-2)
the answer is first picture
Steps 4 and 5 are being used to get the equation in step 6.
Steps 5 and 7 are being used to get the equation in step 8.
Steps 8 and 6 are being used to get the equation in step 9.
In step 14, "similar argument" means to draw segment BD and follow the same logic in steps 3-12.
