You first put a 1 under the 2
than you give them the same denominator(bottom number)
that is 18/9 and 4/9
Now add them together and get 22/9
now make that into a mixed-number by dividing 22 by 9 you get 2.44
So...4/9+2 =2.44
Hope this helps
There are a total of 16 coins, so out of the ratio, that 16 goes on the bottom. Now you have to add up the coins that are NOT quarters and that number goes on the top. So your ratio is 8/16 or 1/2
Answer:
<h3>-6</h3>
Step-by-step explanation:
Let the slope of the first line be m1
Let the slope of the second line be m2
If both lines are perpendicular, then;
m1m2 = -1
Get m1, the slope of the line passing through A (-2, 0) and B (2,-k).
m1 = y2-y1/x2-x1
m1 = -k-0/2-(-2)
m1 = -k/4
Get the slope of the line 3y + 2x = 5
Rewrite the equation;
3y = -2x + 5
y = -2/3 x + 5/3
Hence the slope of the line m2 is -2/3
Since m1m2 = -1, then;
-k/4(-2/3) = -1
2k/12 = -1
k/6 = -1
k = -6
Hence the value of k is -6
the formula we use is
distance = speed * time
In the question we are provided with the info that
speed = 56 mph and
time = 3 hours 45 minutes = 3 + 45/60 hours = 3+ 0.75 hours = 3.75 hours
Now lets plug the values in the formula
distance = speed * time = 56 mph * 3.75 hours
distance = 210 miles
