Answer:
It will take <u><em>80 days</em></u> for the bull calf to reach a weight of 500 kilograms.
Step-by-step explanation:
Given:
The weight of a bull calf is 388 kilograms.
Now, to find the weight of bull calf of how long it will take to reach a weight of 500 kilograms, if it’s weight increases at a rate of 1 2/5 kilograms per day.
Required weight which to be increased = 500 - 388 = 112 kilograms.
Rate of weight increase = ![1\frac{2}{5}=\frac{7}{5}](https://tex.z-dn.net/?f=1%5Cfrac%7B2%7D%7B5%7D%3D%5Cfrac%7B7%7D%7B5%7D)
=
Thus, the time required = ![\frac{required\ weight}{rate\ of\ weight}](https://tex.z-dn.net/?f=%5Cfrac%7Brequired%5C%20weight%7D%7Brate%5C%20of%5C%20weight%7D)
=
=
<em>The time required = 80 days</em>.
Therefore, it will take 80 days for the bull calf to reach a weight of 500 kilograms.
10 students of Elena's classmates like to make jewellery.
<u>Step-by-step explanation:</u>
Let total no.of classmates who liked the jewellery = x
Here, in the given problem, given she asked her classmates '20'. So, it clearly shows that total number of students/classmates = 20. Also, in that, 50% said like to make jewellery. Now find 'x' as below,
![x = 50 \% \text { of } 20](https://tex.z-dn.net/?f=x%20%3D%2050%20%5C%25%20%5Ctext%20%7B%20of%20%7D%2020)
![x = \frac{50}{100} \times 20](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B50%7D%7B100%7D%20%5Ctimes%2020)
![x = 10](https://tex.z-dn.net/?f=x%20%3D%2010)
Hence, the total number of classmates who liked to make Jewellery = 10
Answer:
x=11
Step-by-step explanation:
