Answer:
Given the mass of the object = 15g
Given the volume of the object = 3 mL
Density = ?
Step-by-step explanation:
We have two values of an object that is mass of the object and volume of the object. Now we are required to find the Density of the object. In order to find the density of the object, we have to divide the given mass with the given volume. Below is the calculation of the density.
Density = Mass / Volume
Density = 15g / 3 mL
Density = 5 g/ml
Answer:
The number of ducks Old Mc Donald raises are 23 and the number of cows Old Mc Donald raises are 77.
Step-by-step explanation:
We are given that Old Mc Donald raises ducks and cows. The animals have a total of 100 heads and 354 feet.
Let the number of ducks Old Mc Donald raises be 'x' and the number of cows Old Mc Donald raises be 'y'.
So, according to the question;
- The first condition states that the animals have a total of 100 heads, that means;
-------------------- [equation 1]
{because one head of a duck and one head of cow}
- The second condition states that the animals have a total of 354 feet, that means;
--------------- [equation 2]
{because there are two feet of a duck and four feet of cow}
Now, putting the value of x in equation 2 we get;


y = 77 cows
Putting this value of y in equation 1 we get;
x = 100 - y
x = 100 - 77 = 23 ducks
Hence, the number of ducks Old Mc Donald raises are 23 and the number of cows Old Mc Donald raises are 77.
