Answer:
11 1/2 quarts
Step-by-step explanation:
We need to add the quarts of paint
2 2/4 + 4 3/4 + 4 1/4
Since they all have the same denominator for the fraction, we add the whole numbers
2+4+4 = 10
And the fractions
2/4 + 3/4+ 1/4 = 6/4
This is bigger than 1
6-4 =2 so we have 1 +2/4
10 + 1 + 2/4
11 2/4
We can simplify 2/4 because the top and bottom can be divided by 2
11 1/2 quarts
Josiah and Chana travel at constant and different speeds.
- The point F indicates that after 25 seconds Josiah is 60 meters from the starting line but behind Chana
<h3>How can the what the the point <em>F </em>represent be known?</h3>
Josiah's head start = 10 meters from the start
Josiah's speed = 2 m/s
Chana's speed = 3 m/s
Expressing the distance traveled as an equation, we have;
D = d + s × t
Where;
D = The distance covered
d = The distance from the starting line the runner starts
s = The speed of the runner
t = The time spent running
For Josiah, we have;
D = 10 + 2•t (line <em>a</em>)
For Chana, we have;
D = 0 + 3•t = 3•t (line <em>b</em>)
The above equations are straight line equations.
The point <em>F </em>is on line <em>a</em>, which shows Josiah distance after 25 seconds which is 60 meters. The corresponding point on line <em>b</em>, Chana's distance after 25 minutes is 75 meters.
Therefore;
- The point <em>F </em>indicates that after 25 seconds Josiah is 60 meters from the starting line but behind Chana
