Answer:

the length of the thread remaining is 790 cm

Step-by-step explanation:

Given;

original length of the thread, L₀ = 10 m = 1000 cm

the length of the thread used, L₁ = 210 cm

The length of the thread remaining is calculated as follows;

ΔL = L₀ - L₁

ΔL = 1000 cm - 210 cm

ΔL = 790 cm

Therefore, the length of the thread remaining is 790 cm

The total number of students in the young woman's study group that are from in-state (but not from the school's town) is 80%.

100 - (80 + 7) = 100 - 87 = 13%
