Answer:
4,8
Step-by-step explanation:
let the numbers be x and y
x+y=12
x-y=-4
add
2x=12-4=8
x=8/2=4
4+y=12
y=12-4=8
so numbers are 4 and 8
The triangle inequality requires the third side be in the range
.. 12 -4 ≤ third side ≤ 12 +4
.. 8 ≤ third side ≤ 16 . . . . . . . . . your answer is the number(s) in this range
_____
Some define the triangle inequality using < rather than ≤. Be careful here.
Answer:
4.5
Step-by-step explanation:
First we need to turn the ratio of 1 : 3 into a fraction
1:3 = 1/3
Next we need to square that fraction
1 x 1 = 1
3 x 3 = 9
Then we turn those numbers into a fraction
1/9
We turn the .5 into a fraction
.5/x
And cross multiply both fraction by each other
1/9 x .5/x
1 x X = X
9 x .5 = 4.5
So
4.5 = X
There's a formula for that.
KE = (1/2)mv²
... = (1/2)(2000 kg)(30 m/s)²
... = 900,000 kg·m²/s²
... = 900,000 J
_____
It is helpful to know the relationship between kilograms, meters, seconds, and Newtons or Joules.
1 J = 1 kg·m²/s²
Hey there again,
The first step is to put the data in order, as shown in the diagram below
Five summaries of Town A
Lowest Value = 10
Lower Quartile, = 16.5 (The value falls between 16 and 17)
Median, = 25
Upper Quartile, = 40 (The middle value between 38 and 42)
Highest value = 42
Five summaries of Town B
Lowest value = 0
Lower Quartile, = 4 (The middle value between 0 and 8)
Median, = 9
Upper Quartile, = 20 (The middle value between 19 and 21)
Highest Value = 30
