Y=15/x or xy=15 it seems that a should be 15/x
Answer:
$8.60
Step-by-step explanation:
Let’s find the cost for each item
Apples: 2.5 x 1.30 = 3.25
Grapes: 2.5 x 1.65 = 4.125
Bananas: 2.5 x 0.49 = 1.225
Now we will add all the costs which will give use our total!
3.25 + 4.125 + 1.225 = 8.6
So the answer will be $8.60
Answer:
Anwser is **42** Because if you add 32 and 10 you end up with 42
Step-by-step explanation:
Answer:
W1 = W2 = 50k Joules (assuming W1 and W2 have the same force constant, k)
W1 - W2 = 0
Step-by-step explanation:
Work done in stretching a spring is given by 1/2ke^2
Where, k is force constant and e is extension
e1 = 30cm - 20cm = 10cm
W1 = 1/2k(e1)^2 = 1/2×k×10^2 = 50k Joules
e2 = 40cm - 30cm = 10cm
W2 = 1/2k(e2)^2 = 1/2×k×10^2 = 50k Joules
W1 = W2 = 50k Joules provided W1 and W2 have equal force constant
Therefore, W1 - W2 = 0
