Answer:
7:07pm.
Step-by-step explanation:
There's no way to explain this you just need to know time.
First computer takes x min. For 1 min it does 1/x part of work.
Second computer takes (x+24) min. For one min it does 1/(x+24) part of work.
Both computers for one min do (1/x+1/(x+24)) part of work.
At the same time, both computers for one min do 1/9 part of work.
Answer:
11. ∠B ∠ABC ∠CBA ∠2
17. QR = 12
Step-by-step explanation:
11. ∠B ∠ABC ∠CBA ∠2
17. Given: PS = 18 PR = 15 PQ ≅ RS
It would be good if you could draw a picture for yourself
So, RS = PS - PR
= 18 - 15 = 3
RS = PQ = 3
QR = PS - RS - PQ
= 18 - 3 - 3
= 12
A = 1/2 or 0.5
