The graph shows that at first the ball rises up ; and then it is seen that it goes down and loses height to zero , from which it can be concluded that the height after 10 seconds remains unchanged and therefore the height of the ball after 16 seconds will be zero
L x w x h = volume
volume = 5 x 5 x 5 = 125 cm ^ 3
Answer: the bill for a hamburger is $0.7
the bill for a salad is $1.5
Step-by-step explanation:
Let x represent the bill for a hamburger.
Let y represent the bill for a salad.
The bill for five hamburgers and four salads is $9.50. This means that
5x + 4y = 9.5- - - - - - - - - - - - - - 1
The bill for four hamburgers and five salads is $10.30. This means that
4x + 5y = 10.3 - - - - - - - - - - - - - -2
Multiplying equation 1 by 4 and equation 2 by 5, it becomes
20x + 16y = 38
20x + 25y = 51.5
Subtracting, it becomes
- 9y = - 13.5
y = - 13.5/ - 9
y = 1.5
Substituting y = 1.5 into equation 1, it becomes
5x + 4(1.5) = 9.5
5x + 6 = 9.5
5x = 9.5 - 6 = 3.5
x = 3.5/5 = 0.7
SOLUTION:
If it takes 5 sewing machines 5 minutes to make 5 shirts, then that means:

Answer:
$4
Step-by-step explanation:
We are told that Roxanne:
- Has a checking account only
- Uses online banking
- Uses the bank ATM once a month
- Uses a nonbank ATM twice a month
We need to work out how much it costs for Roxanne to bank with each bank each month, then compare the total costs to see how much Roxanee could save if she switch from East Median to Jasmine bank.
Cost of monthly banking at East Medina Bank:
Checking account services = $6
Online banking = $5 (remember, she doesn't have a linked savings a/c)
ATM (1 use) = $1
<u> nonbank ATM (2 uses) = $6</u>
<u> Total = $18</u>
Cost of monthly banking at Jasmine Bank:
Checking account services = $10
Online banking = $4
ATM (1 use) = $0
<u> nonbank ATM (2 uses) = $0</u>
<u> Total = $14</u>
To calculate the money Roxanne could save by switching to Jasmine Bank, simply find the difference between the monthly costs:
Savings = $18 - $14 = $4
