So assuming that the book is 100% the student has read 45% of the book so far in a time of 37 minutes so if you divide 45 by 37 you get 1 minute and 22 seconds per 1% of the assignment
If you multiply this by 100% you get 122 minutes for the total assignment
Answer: If 169 meters is the longest length, then 154 meters is the shortest length.
Explanation:
The given figure show a box plot.
In a box plot the box is lies between the first quartile Q₁ and third quartile Q₃ . The line between Q₁ and Q₃ represent the median and Q₁ is always less than Q₃.
The end point of the line left side of the box represents the minimum value of the data and the end point of the line right side of the box represents the maximum value of the data.
From the figure we can say that,
Minimum value is 154 and the maximum value is 169.
Since it is given that the 169 meters is the longest length then the shortest length is 154.
So let us set up the equations:
d = rt
d = 12t and plug in r = 12
so after t hours, the faster runner is 12t miles which is
for the faster runner.
d = rt
d = 8t plug in r = 8
so after t hours, the slower runner has 8t miles.
Now if you want to get the distance, simply subtract:
12t – 8t = 4t
Since we need to get the distance of ¼ mile, meaning:
12t – 8t = ¼
= 4(12t – 8t) = 4 x 1/4 -> multiply both sides by the lcd
to clear the fractions
= 48t – 32t = 1
=16t = 1
Get t by dividing both sides by 16 to isolate t.
So the answer is 1/16 which is about 0.0625.
Answer:
2S = F
1.5R = S or R = S/1.5
So flour F and sugar S and raisins R
F + S + R = 550
2S + S + S/1.5. = 550
3S + 1.5S + S = 550*1.5
5.5 S = 550*1.5
S = 100*1.5
S = 150
R= 100
And so flour ie, F = 300
Answer:
$45
Step-by-step explanation:
let's work backwards. We know that it was 20% off, or otherwise 80% of the original cost. Let's represent the original cost with x:
0.8x = 36
Now we solve for x by dividing both sides by 0.8:
x = 45
Thus, the sweater was originally $45
