Answer:
4π mi²
Step-by-step explanation:
s = (∅/360) * πr²
s = (135/360) * π(4²)
s = (135/360)(16) * π
s = 4π mi²
Add the five to each side.
then square it to get rid of the square root
2x+13=(5+x)^2
2x+13=x^2+10x+25
2x=x^2+10x+12
x^2+8x+12=0
(x+6)(x+2)
x+6=0
x+2=0
answers are -2 and -6, however, when pluging -6 in it doesnt work, so it is only -2.
x and y i think, I haven't done that in a long time.
520 minutes is greater because 8 hours is 480 minutes
Answer:
28
Step-by-step explanation:
Since the score is the sum of all cards a player has, the way to make it smallest is to use the smallest cards. So the 7 smallest cards are 1, 2, 3, 4, 5, 6 and 7. So you want to add these up. This gets 28
