Formula of the circle
(x-a)² +(y-b)² = r²,
where r is a radius, (a,b) - coordinates of the center.
So,
x² + y² = 49
(x-0)² + (y-0)² = 49.
Center of this circle has coordinates (0,0).
x² + y² = 7²
r = 7
Answer is C.7.
P vaires directly with d means
p=kd
7=k3
divide by 3
7/3=k
28=(7/3)d
times 3/7 both sides
84/7=d
12=d
B
Brand A is. Just divide 100 (100% of a pickle) by each number, so 100 divided by 240 and 100 by 325. Then you multiply them by the fraction of 100, which 1/3 is 33.3% and 1/2 is 50%. It comes very close but A is the lowest.
Answer:
0.75 lbs.
Step-by-step explanation:
Okay, this one is more simple. To find the weight of each book, You have to solve this division problem:
15/20
If you divided it the other way around, you would be saying each book weighed 1.33 pounds. That wouldn't be correct because then you would have over 20 lbs. of books, when you only have 15.
So, the answer is 0.75 pounds.
