Answer:
The equation that models the situation is [tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex].
Step-by-step explanation:
Let suppose that effects from air friction and Earth's rotation can be neglected, so that the softball can be modelled experiment a free fall, that is, an uniform accelerated motion due to gravity. From we know the initial velocity and position of the position and we can determine the final position of the ball as a function of the final velocity:
[tex]v_{f}^{2} = v_{o}^{2}+2\cdot a \cdot (s_{f}-s_{o})[/tex] (1)
Where:
[tex]s_{o}[/tex], [tex]s_{f}[/tex] - Initial and final position of the softball, measured in feet.
[tex]a[/tex] - Acceleration, measured in meters per square second.
[tex]v_{o}[/tex], [tex]v_{f}[/tex] - Initial and final velocities of the softball, measured in feet per second.
If we know that [tex]v_{o} = 50\,\frac{ft}{s}[/tex], [tex]a = -32.174\,\frac{m}{s^{2}}[/tex] and [tex]s_{o} = 4\,ft[/tex], then the equation that models the situation is:
[tex]v_{f}^{2} = 2500-64.348\cdot (s_{f}-4)[/tex]
Then, we clear the final position of the softball:
[tex]-\frac{v_{f}^{2}-2500}{-64.348} = s_{f}-4[/tex]
[tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex]
The equation that models the situation is [tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex].

Step-by-step explanation:
Turn the percentage into a decimal.
50% = 0.5
Divide.
31 / 0.5 = 62
Best of Luck!
Answer:
62
Step-by-step explanation:
50% is technically 1/2 right?
So, if 31 is half of this mysterious number then we just need to times 31 by 2.
Therefore, 31 * 2 = 62.
We can check this by multiplying 62 by .50 (remember that when using percents in an operation we move the decimal over twice)
62 * .50 = 31
I hope this helps!!

Chuck and Holly are saving money to buy a car. Chuck has $500 already and is going to save $100 a month. Holly has $1000 and plans on saving $50 a month. In the space to the left, write an equation that shows when Chuck and Holly will have the same amount of money. What is the equation
Answer:
10 months
Step-by-step explanation:
Step one
Given
Chuck has $500
Chuckle wants to save $100 monthly
Let the number of months be x
And the total be y
So
Y=500+100x--------1
Holy has $500
Chuckle wants to save $500 monthly
Let the number of months be x
And the total be y
So
Y=1000+50x--------2
Equate 1 and 2
500+100x=1000+50x
1000-500=100x-50x
500=50x
x=500/50
x=10

$36 - $17.85 =
Answer and Step-by-step explanation:
36 dollars minus 17.85 dollars equals $18.15, or 18 dollars and 15 cents.
All you have to do is subtract 36 by 17.85
36 - 17 = 19
100 - 85 = 15
1 is subtracted from 19 because of the decimal.

members of a soccer team raised $741.15 to go to a tournament. They rented a bus for $250 and budgeted $25.85 per player for meals. they will spend all the money raised. write and solve an equation to determine the number of players the team could bring to the tournament
9514 1404 393
Answer:
19 players
Step-by-step explanation:
The total being spent is ...
bus cost + (per player cost) × (number of players) = total raised
250 + 25.85p = 741.15
25.85p = 491.15
p = 491.15/25.85 = 19
The team could bring 19 players to the tournament.

According to the scale on a map, 1 inch on the map = 12 miles. How many miles are represented by 4 inches on the map?
Answer:
60 miles
Step-by-step explanation:
So if 1 inch = 12 miles, you need to find 4 inches. There are multiple ways to achieve this. However ratios/proportions might be easiest.
if 1/12 = 4/x, x is the value of miles. Cross multiply so you get this:
1 4
- = - = 60 = x
12 x
If x equals 60, that means that 4 inches equals 60 miles on the map.
You could also just find an equal fraction by multiplying the top and bottom both by 4.
The miles are represented by 4 inches on the map, if the scale on a map, is 1 inch on the map = 12 miles is 48 miles.
What is multiplication?One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.
Given data:
According to the scale on a map, 1 inch on the map = 12 miles
Calculate the miles as shown below,
Miles in 4 inches on the map = 4 × miles in 1 inch on the map
Miles in 4 inches on the map = 4 × 12 = 48 miles,
Therefore, the miles are represented by 4 inches on the map, if the scale on a map, is 1 inch on the map = 12 miles is 48 miles.

Answer:
Im pretty sure the first is -2 and -3. then -4 and-10
Step-by-step explanation:
thats all i know srry
1)
First box: -10
Second box: -2
Plug in the corresponding numbers to the corresponding boxes:
[(-10)/(-2)]/5 = 1
Simplify. First, solve the bracket. Note that when you divide two negative numbers, the answer will be positive.
(-10)/(-2) = 5
Next, divide the brackets:
[5]/5 = 1
1 = 1 (True)
2)
First box: -5
Second box: -3
Plug in the corresponding numbers to the corresponding boxes:
[5 - (-5)]/[(-3) + 8] = 2
Simplify. First, solve the brackets, then divide:
[5 - (-5)] = [5 + 5] = 10
[-3 + 8] = [8 - 3] = 5
Divide:
10/5 = 2
2 = 2 (True)
3) Use the last two numbers:
First box: -11
Second box: -4
Plug in the corresponding numbers to the corresponding boxes:
(-([-11]) x 2)/(6 + [-4]) = 11
-(-11 x 2)/(6 - 4) = 11
-(-22)/(2) = 11
22/2 = 11
11 = 11 (True).
