Let x = hours to meet
train one has a 2 hour head start or 210 km head start
210 + 105x = 135x
30x = 210
x = 7 hours to meet
We have that
(14/3)=(x/y²)-----------> 14*y²=3*x
then
(14/x)=(3/y²)
the answer is
3/y²
x=4 because if you add 7 to 10 you get -2x-3=-14x then you add -2x to -14x and you get -3=-12 then you divide by -3 and -12 to get 4
(88sin20)(t - 16t²) = 0
(8(0.3090169944)(t - 16t²) = 0
(2.472135955)(t - 16t²) = 0
2.472135955t - 39.55417528t² = 0
Answer:
1134 cubic inches of soil
Step-by-step explanation:
You can split the shape apart and then add the volumes together at the end.
The bottom shape is 21x7x2
=294
The top shape is 12x10, and the last side can be foundfrom the other shape’s depth, 7.
12x10x7
=840
294+840=1134
