Answer from: Rogeartest4

The ball's speed if it took 0.5 seconds for the ball to hit the wall is 8m/s

The formula for calculating the speed of the ball is expressed as:

Speed = Distance/Time

If the ramp is 2.5m long and the distance from the end of the ramp to the wall is 1.5m, the total distance will be 2.5+1.5 = 4.0m

Given the following

Distance = 4.0m

Time = 0.5 seconds

Substitute the given values into the formula as shown:

$Speed =\frac{2.5+1.5}{0.5}\\ Speed = \frac{4.0}{0.5}\\Speed = 8m/s$

Hence the ball's speed if it took 0.5 seconds for the ball to hit the wall is 8m/s

Answer from: tonio638

$\text{ Speed of ball}=8 \frac{\text{ meters}}{\text{ second}}$

Step-by-step explanation:

To find speed of ball we will use $Speed=\frac{Distance}{Time}$ formula.

To find distance traveled by ball we will add length of ramp and distance from the end of ramp to the wall.

2.5+1.5=4

Now we will substitute our values in speed formula to find our answer.

$\text{ Speed of ball}=\frac{4\text{ meters}}{0.5\text{ seconds}}$

$\text{ Speed of ball}=\frac{40\text{ meters}}{5\text{ seconds}}$

$\text{ Speed of ball}=8 \frac{\text{ meters}}{\text{ second}}$

Therefore, speed of ball will be 8 meters per second.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
