First, you have to make them into decimals to make it easier. 2/8 equals 0.25.
1/5 and 2/10 equal 0.2. 0.2+0.2+0.25 equals 0.65 so if you suppose Jon's money is 1 dollar, he has 35 cents left. In a fraction, 0.35 is 35/100. If you simplify 35/100, it's 7/20.
Answer: Jon has 35/100 or 7/20 or his money left.
I hope it helps!
To calculate the time it takes for the penny to hit the ground, we use the formula given relating time and the height of the penny. We calculate as follows:
h = 4.9 (t²) + v0 t + h o
150 = 4.9 (t²) + 0 t + 0
0 = 4.9 (t²) - 150
t = 5.53
t = -5.53
Since in reality there is no time that is negative, the answer would be 5.53 units of time.

8+4=12
12-2=10
Answer:
<h3>x = 3/2 ± √(61/20)</h3>
Step-by-step explanation:
5x² - 15x - 4 = 0
Add 4 to both sides.
5x² - 15x = 4
The coefficient of 5x² is 5, divide both sides by 5.
x² - 3x = 4/5
The coefficient of -3x is -3. Let b=-3.
Then we need to add (b/2)^2=9/4 to both sides to complete the square.
Add 9/4 to both sides.
x² - 3x + 9/4 = 61/20
Factor left side.
(x-3/2)² = 61/20
Take square root of both sides.
x-3/2 = ± √(61/20)
Add 3/2 to both sides.
x = 3/2 ± √(61/20)
Answer:
C. $6 per hour.
Step-by-step explanation:
Pick a convenient point on the graph. The rate of change is the
y coordinate / x coordinate.
So we pick the point near the top right corner where y = 30 and x = 5 which gives us the answer 30/5 = 6.
