Answer:
diameter = 4
Step-by-step explanation:
A=pi*r^2
12.566=pi*r^2
3.99988202979=r^2
r=1.99997050723
diameter = 2r
d=2(1.99997050723)
d=3.99994101446 =4
Answer:
50 · (2 x 10^6) = 1 × 10^8
Step-by-step explanation:
In scientific notation a large number is converted to an equivalent decimal number between 1 and 10, multiplied by 10 raised to some power. Very small numbers are converted to an equivalent decimal number between 1 and 10, multiplied by 10 raised to some negative power.
Answer:
This function s a linear relationship because this function increases about a consistent slope. The equation is 2x+5, where 2 is the slope.
Step-by-step explanation:
6(times the larger number, y) = (the smaller number, x) +18
6y=x+18
(2 times the larger number) - (the smaller number) = 6
2y-x=6
Answer:
x=1 and x=-4
