Answer: 7.81 feet
Step-by-step explanation:
This scenario forms a right-angled triangle where Ruby's height of 5 feet is the height of the triangle. Her 6 feet long shadow is the length of the triangle and the distance from the top of her head to the end of the shadow is the hypotenuse.
This can therefore be solved by the Pythagorean formula:
c² = a² + b²
where ;
c = hypotenuse
a = height
b = length
c² = 5² + 6²
c² = 25 + 36
c² = 61
c = √61
c = 7.81 feet
Answer:


Step-by-step explanation:
Given


Required
Which completes the model
Let the remaining probability be x.
Such that:

Make x the subject

So, we have:

Solve



This mean that the remaining model must add up to 1/2


Take LCM


This is false because: 


Take LCM



This is true


Take LCM



This is true
Other options are also false
Answer:
s = 19.0
Step-by-step explanation:
To find s, use the Pythagorean Theorem.
a² + b² = c²
9² + b² = 21²
81 + b² = 441
b² = 360
b = √360
b = 18.97366596 ⇒ 19.0 (rounded to the nearest tenth)
So, s = 19.0.
Hope that helps.

Step-by-step explanation:
Since forty-five basketball players participated in the tournament and a 3-person team wants to be formed, the equation to find the number x of 3-person teams that they can form will be:
3x = 45
x = 45/3
x = 15
Therefore, 15 3-person team can be formed.
