Answer:
SU=25
Step-by-step explanation:
We can set up a ratio as STU and SQR are similar because of the SAS similarity theorem.
TQ:SQ
SQ=ST+TQ=10+6=16
6:16=3:8
Therefore the ratio of STU:SQR is 3:8
We can use this to find SU
UR:SR=3:8
15:SR=3:8
Cross multiply
3SR=120
SR=40
SU=SR-UR
SU=40-15
SU=25
1) Slope equals -0.667/2.000=-0.333
x-intercept =12/1=12.00000
y-intercept =12/3=4
x+3y=12
Answer: 4
2) Slope equals 2
x-intercept=5/2=2.5000
y-intercept=5/-1=-5.00000
Answer: -5.00000
If you are looking for the median number, it would be the number in the middle which is 50
Answer:
to verify this answer you need to substitute the answer you got for x
Step-by-step explanation:
7(3)-2=19
21-2=19
19=19
this means that you are correct
Answer:
2nd friend heading west
Step-by-step explanation:
This is actually pretty easy to explain.
You and a friend are near a tree and decide to walk away from it. At the beggining you walked 15 yards and your friend too, and then, there's the turn of event. You walked 8 yards toward north east, and your friend 8 yards towards south west.
The key to know which is further from the tree is the angle of turning of both. We need to calculate the component in x from both persons, and then, add it to the previous 15 yards. This way we will know who is further.
Let's begin with the 1°, the one who's heading east:
X = 15 + 8 cos45° = 20.66 yards
Now the friend heading west:
X = 15 + 8 cos40° = 21.13 yards
With these results we can conclude that the 2nd friend is further from the tree.
Hope this helps
