Answer:
3.125
Step-by-step explanation:
-14÷(-4.48)
14÷(4.48)
divide that you will get 3.125
25/8, 3 1/8
is its alternative form.
Answer:
30
Step-by-step explanation:
you plug in k with 3 and j with 5
4 times 3 + 6(5 – 2) = 30
Volume is a three-dimensional scalar quantity. The volume of the space between the cylinder and the two cones is 1184.43183 cm³.
<h3>What is volume?</h3>
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Given the circumference of the base is 61 cm, therefore, the radius of the base will be,
Circumference = 61 cm
2πR = 61
R = 61/(2π) = 9.70845 cm
The volume of the cylinder(Outside shell) can be written as,
Volume = πR²×H
= π× (9.70845)² ×12
= 3553.29326 cm³
The volume of the two identical cones will be,
The volume of the cone = 2× (1/3) × π × R² × H
= (2/3)×π×(9.70845²)×12
= 2368.86143 cm³
The volume of the space between the cylinder and the two cones is,
The volume between space = 3553.29326 cm³ - 2368.86143 cm³
= 1184.43183 cm³
Hence, the volume of the space between the cylinder and the two cones is 1184.43183 cm³.

The number of cows is given by

So, after
years, the number of cows will be

We want this number to be twice as much as the original:

First of all, we can cancel 14 from both sides:

Finally, on the right hand side, we can use the exponent rule

to get

To solve this equation, we must impose that the two exponents are the same:

And clearly this is true if and only if
. So, it will take 5 years for the cow heard to double in number.
You can do the exact same steps to find the doubling time for the sheeps.
