Answer:
7.74cm ^2
Step-by-step explanation:
a=pie * r ^2
3.14*3^2=3.14*9=28.26 then you know all sides of a square are equal and 3 is half of 1 side so 6*6-=36 36-28.26=7.74
Answer:
a = 20
Step-by-step explanation:
The mean is calculated as
mean = 
= 
= 
Then
= 27 ( multiply both sides by 5 to clear the fraction )
115 + a = 135 ( subtract 115 from both sides )
a = 20
Step-by-step explanation:
equation: m-3n=16
Solution,
or, m - 3n = 16
or, m - 3×8 = 16
or, m - 24 = 16
or, m = 16 + 24
or, m = 40
Therefore, the value of m is '40'
Answer:
answers below and explained
Step-by-step explanation:
a) 2 (2 times 3) + 5 (3)
2 (6) + 5 (3)
12 + 15
= 27
b) a = 3 + 3
a = 6
c) 3(2a+1) - 6a + 7 = 10
6a + 3 - 6a + 7 = 10
3 + 7 = 10
For each problem, I substituted the information given. If you have any questions, feel free to ask below!
1 + 2 + 3 + 4 + 5 + 67 + 8 = 90
I think this is what you mean right?
