Answer: -2y < -20
Step-by-step explanation:
Let x be the resistance of the wire with the larger diameter.
x = (0.456 x (0.01)^2)/(0.0401)^2 = 0.0284 ohms
The answer is 0.0284 ohms.
Answer:
Step-by-step explanation:
9 = 3 × 3
12n = 2 × 2 ×3 × n
Greatest common factor = 3
9+12n = 3×3 +3×4n = 3(3+4n)
159 children and 351 adults swam at the public pool that day.
Step-by-step explanation:
Total people = 510
Total receipts worth = $1116.00
Cost for one child = $1.50
Cost for one adult = $2.50
Let,
x be the number of children.
y be the number of adults.
According to given statement;
x+y=510 Eqn 1
1.50x+2.50y=1116.00 Eqn 2
Multiplying Eqn 1 by 1.50
Subtracting Eqn 3 from Eqn 2;
Putting y=351 in Eqn 1
159 children and 351 adults swam at the public pool that day.

So, I converted the grams to kilograms, and the smallest cat was the Canada Lynx, being 15.9kg and the largest cat was the mountain lion, which was 85kg. So since it asks for the difference, we subtract.
85-15.9=69.1
Therefore the answer is B. 69.1kg
