Answer:
C = 7π
Step-by-step explanation:
Diameter: 7 feet
Formula: C = πd (Circumstance = π × Diameter)
C = 7π
5(x + 2) + 6(x - 3) = 25
Simplify.
5x + 10 + 6x - 18 = 25
Add like terms.
(5x + 6x) + (10 - 18) = 25
Simplify.
11x - 8 = 25
Add 8 to both sides.
11x = 25 + 8
Simplify.
11x = 33
Divide both sides by 11.
x = 3

ANSWER
correct to 3 decimal places is 
EXPLANATION
We start counting from the first number after the decimal point.
So starting from 2, we count 3 decimal places to the right and land on 4.
Next, we check to see if the number after 4, is greater or equal 5, then we round up, else we round down.
Since that number is 5, it is greater than or equal to 5.
Therefore we round up to obtain 
We use this formula to calculate the sum of all interior angles of a regular polygon; 180(n-2) , n= number of sides
so 180(5-2) = 540
each interior angle = 540 ÷ 5 = 108
Answer:
Step-by-step explanation:
Red:black = 1:1
Red cards = x
Black cards =x
x + x = 48
2x = 48
x = 48/2
x = 24
No. of red cards = 24
No of black cards = 24
Now 8 red cards are removed
So, No. of red cards = 24 - 8 =16
Red: Black = 16:24

Red: Black = 2:3
