Answer:
in order from images displayed, x = 20, x = 6, x = 5.5
Step-by-step explanation:
4x - 8 + 6x - 12 = 180
10x -20 = 180
10x = 200
x = 20
5x - 1 = 29
5x = 30
x = 6
14x - 6 = 12x + 5
2x = 11
x = 5.5
Answer:
58.4
Step-by-step explanation:
Runner 1 ran 14.85 and Runner 2 ran 14.05 from there you need to add the two together and you get 28.90. From there you can add Runner 3 and Runner 4 time together and you get 29.50.
After that you add them together and you get 58.4

Answer:
There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.
Step-by-step explanation:
is the number of different combinatios of x objects from a set of n elements, given by the following formula.
In this problem, we have that:
Total number of combinations:
Desired combinations:
It is 1 one 5(contamined) and 2 of 17(non contamined). So:
What is the probability that exactly 1 of the tested bottles is contaminated?
There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.
Answer:
h+r=34
r=34-h.....1
total surface area=2πr(r+h)
2992=2πr×34
2992/34=2πr
88/2=22/7×r
44×7/22=r
r=2×7=14cm
