Answer:
Kendal will be 60 meters away from the library after 80 seconds and again after 100 seconds.
Step-by-step explanation:
|540 − 6t| = 60.
Solve an absolute value equation by writing it as two separate linear equations and solving each one:
540 − 6t = -60 540 − 6t = 60
-6t = -600 -6t = -480
t = 100 t = 80
Answer:
![v = \pi \times {r}^{2} \times h](https://tex.z-dn.net/?f=v%20%3D%20%5Cpi%20%5Ctimes%20%7Br%7D%5E%7B2%7D%20%20%5Ctimes%20h)
Step-by-step explanation:
height=11km
diameter=10km
radius=diameter÷2
=10÷2
=5km
now,
volume=
![\pi \times {r}^{2} \times h \\ \frac{22}{7} \times {5}^{2} \times 11 \\ \frac{6050}{7} \\ 864.3 \: {km}^{3}](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20%20%5Ctimes%20h%20%20%5C%5C%20%20%5Cfrac%7B22%7D%7B7%7D%20%20%5Ctimes%20%20%7B5%7D%5E%7B2%7D%20%20%5Ctimes%2011%20%20%5C%5C%20%5Cfrac%7B6050%7D%7B7%7D%20%20%5C%5C%20864.3%20%5C%3A%20%20%7Bkm%7D%5E%7B3%7D%20)
Answer:
(-5, -8)
Step-by-step explanation:
-3x+3y=-9
-3x+y=7
----------------
simplify -3x+3y=-9 into x-y=3
----------------------------------------
y=x-3
-3x+y=7
------------
-3x+(x-3)=7
-3x+x-3=7
-2x-3=7
-2x=7+3
-2x=10
x=10/-2=-5
y=-5-3=-8
x=-5, y=-8
