Answer:
The answer to your question is the first rain lasted 40 hours and the second rain lasted 30 hours.
Step-by-step explanation:
Data
1st 15 ml/h = x
2nd 30 ml/h = y
Total time = 70 h and 1500 ml
1.- Write 2 equations
First rain + second rain = 70 h
x + y = 70 (I)
15x + 30 y = 1500 (II)
2.- Solve equations by elimination
Multiply first equation by -15
-15x - 15y = - 1050
15x + 30y = 1500
0x + 15y = 450
y = 450 / 15
y = 30 h
x + 30 = 70
x = 70 - 30
x = 40 h
3.- Conclude
The first rain lasted 40 h and the second rain lasted 30 h.
Answer:
The plant grows 1 cm every day is the incorrect statement
Step-by-step explanation:
The graph shows that for every 10 days the plant grows 1 cm
10/2 = 5
so in 5 days the plant would grow half of what it does in 10 days so 1/2 or 0.5 cm
10/10 = 1
so in 1 day the plant would grow a tenth of what it does in 10 days so 1/10 or 0.1 cm
Answer:
m = 12f
Or
m/12 = f
Step-by-step explanation:
The conversion from inches to feet involves a constant factor of variation which is 12. Inches is a smaller unit while feet are obtained by dividing the inches with 12.
As we know,
1 foot = 12 inches
Given in the question:
m = measurement in inches
and
f= measurement in feet
Hence the equation will be:
m = 12f
Or
m/12 = f ..
Answer:
2, 0.2, 0.02
The first number is 2000. The term to term rule is 'divide by 10'.
Step-by-step explanation:
To calculate the next term, divide the previous term by 10:
2000 ÷ 10 = 200
200 ÷ 10 = 20
Therefore, the next three terms will be:
20 ÷ 10 = 2
2 ÷ 10 = 0.2
2 ÷ 10 = 0.02
<u>Term to term rule</u>
To work out the term to term rule, give the initial number of the sequence and then describe the pattern:
The first number is 2000. The term to term rule is 'divide by 10'.
