The expression for the kinetic energy is mass times velocity squared over two
For the first question that gives us 2,25 joules
If the ball is at the given height then it has a further 60 Joules in potential energy.
Answer is D
Answer:
5
Step-by-step explanation:
10% = 0.1
0.1*50 = 5
Answer:
Step-by-step explanation:
x = cost of drink
y = total cost
First information: "one large pizza and 3 medium drinks cost $21.96":
3a + b = 21.96
Second information: "one large pizza and 6 medium drinks cost $30.93":
6a + b = 30.93
{3a + b = 21.96
{6a + b = 30.93
{- 3a - b = - 21.96
{6a + b = 30.93
3a = 8.97
a = 2.99
3a + b = 21.96
3•2.99 + b = 21.96
8.97 + b = 21.96
b = 21.96 - 8.97
b = 12.99
Each drink costs $2.99 and each pizza costs $12.99. The linear function rule is:
y = 2.99x + 12.99
I hope I've helped you.
Hey there! :D
That's like saying:
-2*-2*-2
-2*-2=4
4*-2= 8
"D" -8 <== the answer
I hope this helps!
