Since 2w, w, and 69 make up a triangle, their degrees have to add up to 180.
2w + w + 69 = 180
3w + 69 = 180
We need to isolate w:
3w = 111
w = 37
Let’s say the block is a and the neighbourhood is b
2a+b= 10 (equation x)
2a+4b=31
3b=21 mins so b=7 mins
so then take x and put in 7 so
2a + 7=10
2a = 10 - 7 = 3
a = 1.5
That’s how I would do it not sure if it is right but hope it helps
Answer:
Any value with a three on the one hundred thousands place. For example 1,335,892
Mass × gravitational energy × height
= gravitational potential energy
= joules
by interrelating the formula,
mass (unknown) × 10 × 629.9
= 2033.76
unknown = 0.32??
this is my working ^ but I'm not positive that it's 100% correct!
