6.8
Step-by-step explanation:
simply subtract the length of RT from RV
13.1 - 6.3
Answer:
6.78ft/sec
Step-by-step explanation:
From the question, dx/dt= 3.9 ft/sec
We are looking for Dy/dt
From geometry,vof this case the relationship between x and y is needed here, there is two similar triangle that exhibited by the man and the lamb
12/y= 5.1/(y-x)
Then ,cross multiply, we have
12(y-x)=5.1y
12y-12x=5.1y
12y-5.1y=12x
6.9y=12x
y=( 12/6.9)x
Differentiating implicitly the bother sides with respect to t, we have
Dy/dt= ( 12/6.9)dx/dt
But dx/dt= 3.9 ft/sec
Then Dy/dt= ( 12/6.9)× 3.9
Dy/dt=6.78ft/sec
Hence, the rate that the tip of the person's shadow moves away from the lamppost when the person is 9 ft away from the lampost is 6.78ft/sec

Answer:
40 more pieces
Step-by-step explanation:
Cody wants to EQUALLY divide 680 candy amongst 45 friends.
That can't be possible because 45 doesn't evenly go into 680. If we do the division, we see:
680/45 = 15.11
So there are some remaining. How many?
45 * 15 = 675
So, the rest are remaining (680 - 675 = 5)
For Cody to equally distribute, he needs how many more? That number should be multiple of 45.
Since 45 * 15 = 675 which is less than 680, to get next number that 45 goes into, we do 45 * 16 = 720
Cody already has 680, he needs 720 altogether for EQUAL SHARE. He would need:
720 - 680 = 40 candy more
Answer:
158cm
Step-by-step explanation:
Data obtained from the question. This includes:
Height of first snow ball (H1) = 7/10m
Height of 2nd snow ball (H2) = 1/2m
Height of 3rd snow ball (H3) = 38cm
Total height of snow man (HT) =?
Next we shall covert from m to cm.
This is illustrated below:
For the first snow ball
1m = 100cm
7/10m = 7/10 x 100 = 70cm
For the 2nd snow ball:
1m = 100cm
1/2m = 1/2 x 100 = 50cm
Now we can obtain the height of the snow man as follow:
Height of first snow ball (H1) = 70cm
Height of 2nd snow ball (H2) = 50cm
Height of 3rd snow ball (H3) = 38cm
Total height of snow man (HT) =?
HT = H1 + H2 + H3
HT = 70 + 50 + 38
HT = 158cm
Therefore the height of the snow man in cm is 158cm
