-15
Step-by-step explanation:
Remember to follow PEMDAS. PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Solve the parenthesis:
(2 + 8 - 8) = (10 - 8) = 2
Divide: -30/2 = -15
-15 is your answer.
Area of square = 15 x 15 = 225 cm^2
area of circle = pi r^2 = (3.14)(15)(15) = 706.5 cm^2
1/4 of circle = 706.5 / 4 = 176.6
so area of yellow region = 225 - 176.6 = 48.4 cm^2
answer
48.4 cm^2
2x-x-7=0
3x-7=0
add 7 to 7 and 0, so then we cross out 7-7, and then
3x=7, bc u change the subtraction to addition, sr if thst doesn't make sense but 3x=7 is the answer
Answer:
m ≥ 0
Step-by-step explanation:
Since the cost is represented by c = 0.12m, the domain should be a positive number, this is because number of minutes can't be written in negative. Therefore, the most reasonable number for the domain would be the set of positive whole numbers which means, m≥0.
Answer:
$204.4
