To solve, you need to find the least common multiple of the denominator.
In this case, its 30.
3*9= 27/30
1*10 = 10/30
She walked 37/30 miles or 1 mile and 7/30th of a mile
Answer:
The answer is 0.97
Step-by-step explanation:
Hi, we need to use the log properties taking into account that Ln(2) is aprox. 0.69 and Ln(3) is aprox. 1.10. I think you can understand better as we solve it, so here it goes.

Since:


Then

Now, we have everything where we want it, in terms of Ln(2) and Ln(3), now it is easy to solve.


Best of luck.

Step-by-step explanation:
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
