Assuming this question is trying to enquire as to how many bottle of
water there are in each case, you simply need to divide 162 by 9 to find
the answer, which is that there are 18 bottles of water in each case.
Answer:
390
Step-by-step explanation:
10% = 39
39 x 10 = 390
390 = 100%
The formula for weight in linear function is y= 7.7x + 7
<u>Step-by-step explanation:</u>
Given that,
- The weight of the born baby = 7 lbs
- The weight of the baby at 10 years = 84 lbs.
To find the linear function, the rate of change of weight must be calculated.
<u>To find the rate of change of the baby's weight:</u>
The change in the weight is from 7 lbs to 84 lbs.
- The total change = 84 - 7 =77
- The rate of change = 77 / 10 years = 7.7
Therefore, the rate of change of weight of the baby is 7.7 lbs.
This means that, every year the weight has been increased by 7.7 lbs and in 10 years the baby gained a weight of 84 lbs.
<u>From this information, the linear function is given as :</u>
Total weight = 7.7(number of years) + born weight.
⇒ y= 7.7x + 7
where,
- The born weight is 7 lbs.
- y is the total weight of the baby
- x is the number of years
Answer:
2300 liters of water.
Step-by-step explanation:
The volume of the barrel is 4.6 m^3, and we know that this is half--filled with water.
Then the total volume of water inside the barrel is:
(4.6 m^3)/2 = 2.3 m^3
So we have 2.3 m^3 of water, and we want to write this in liters.
We know that 1 liter = 0.001 m^3
then:
1 = (1 L)/(0.001 m^3)
Now we can rewrite:
2.3 m^3 = (2.3 m^3)*1 = (2.3 m^3)* (1 L)/(0.001 m^3) = (2.3 m^3/0.001 m^3)* 1L
2.3 m^3 = 2300 L
So we have 2300 liters of water in the barrel.
