The answer for this question is d
hope it helps
Track A takes 20 minutes
Track B takes 15 minutes
In 1 minute track be will do a fraction of 1/20, while track B will do 1/15
Both tracks in a minute = 1/20+1/15
= 35/300
Therefore the two tracks will take 300/35 minutes to fill the 200 cubic feet
That is 300/35
= 8.57 minutes
≈ 9 minutes
17/20 x -12/34 =-3/10
Multiply the top to top and the bottom to the bottom
then reduce it to the lowest term
Answer:
D. 211
Step-by-step explanation:
180-19=161
161+50=211
19+(211(x)-50)=180
Looking at the coordinates of the points, we can see that PQ is 4 units.
Since both P and Q have the same y coordinate, we can now start to look at the x coordinate. Since they have the same y coordinate, that means that to find the length of the segment, we have to take the absolute value of the subtraction of the coordinates of the x value of each of the points. -3 - 1 is -4. The absolute value of -4 is 4, meaning that PQ is 4 units long.
