Answer:
true?
Step-by-step explanation:
Diameter = 30
30/2 = 15 15 is the radius
To find area:
3.14 x 15 x 15 = 706.5
706.5 is the answer
Answer:
Step-by-step explanation:
Ill try to break this down, simply:
When we talk about percentages we are talking about how much part of something we have and the percent sign is a just a symbol representing that.
Lets say we have 2 out of 10 apples and we need to convert this to a percentage
First think about how many apples we have in total... and that would be 10, and then how many apples we currently have being 2:
So if we put the part that we have over the whole thing we get:
So now lets turn this into a decimal, when its something over 10 its really easy, all we have to do is move the decimal back one place!
So we have 2 and if we move the decimal back one place we get .2 or 0.2
Now we have our decimal, to convert this into a percentage all we have to do is multiply our decimal by 100
So:
0.2 x 100 = 20%
All you do when you multiply by 100 is move the decimal back over 2 places one place for each zero so:
0.2 --> 2. --> 20.
Which gives us again 20%
The "step 2" that Malik should take in order to solve the given system of equations is to add both equations.
Given to us
Step 1: Multiply the first equation with 3, while the second equation with 4,
6x + 12 y = 60
20x - 12 y = 44
Step 2: Add both the equations,
(6x + 12y) + (20x - 12y) = 60+44
Step 3: caluculate the value of x,
x = 4
Step 4: Substitute the value of x in equation 1,
2(4) + 4y = 20
8 + 4y = 20.
4y = 12
Y = 3
Step 5: The solution is (4, 3).
Hence, the "step 2" that Malik should take in order to solve the given system of equations is to add both equations.
