I think maybe 3) would make the most sense because she wants a random sample of students and the other options are specific on the type of students.
Answer: Try x=3+2 root46 over 5
Or 3-2root46 over 5
Step-by-step explanation:
Answer:
x-7
Step-by-step explanation:
7x - 18 = 10x + 3
Subtract 7x from each side
7x-7x - 18 = 10x-7x + 3
-18 = 3x+3
Subtract 3 from each side
-18-3 = 3x
-21 = 3x
Divide by 3
-21/3 =3x/3
-7=x
Answer:
I would choose two 12 inch pizza if I want more pizza as two 12 inch pizzas have larger circumference than one 18 inch pizza
c=πd
circumference= pie × diameter
c=2πr
circumference= 2×pie×radius
A=πr²
Area= pie×square radius
Pie= 22/7, 3.14( depends on the question, sometimes the value of pie will be given in the question)
radius= half of diameter
To find perimeter of circle use 2πr
To find area of circle use πr² or πd
