Answer:
c =
Step-by-step explanation:
Given
15 = - 3(2c + d) ( divide both sides by - 3 )
- 5 = 2c + d ( subtract d from both sides )
- 5 - d = 2c ( isolate c by dividing both sides by 2 )
= c
Answer:
h ≈ 77 cm
Step-by-step explanation:
Let us convert the liters to cm³.
Smaller barrel
0.001 litres = 1 cm³
100 litres = 100000 cm³
Larger barrel
0.001 litres = 1 cm³
160 litres = 160000 cm³
For a similar solid figure the cube of their corresponding sides is equal to the volume ratio.
This means
h³/90³ = 100000/160000
cube root both sides
h/90 = ∛100000 / ∛160000
h/90 = 46.4158883/54.2883523
cross multiply
54.2883523h = 46.4158883 × 90
54.2883523h = 4177.429947
divide both side by 54.2883523
h = 4177.429947/54.2883523
h = 76.9489175858
h ≈ 77 cm
Answer: 12:39 AM
Step-by-step explanation: it would be 12:39 because 34 hours is 2 days with a leftover 10 hours. The 89 minutes include an hour so it becomes 11 hours and 29 minutes, add this number to 1:10 and there you go
First, did you mean 4y - 6x = 15?
