Answer:
165.8 ft (nearest tenth)
Step-by-step explanation:
We can use the tan trig ratio to calculate the height of the tower.
where:
= the angle- O = the side opposite the angle
- A = the side adjacent the angle
From inspection of the diagram:
- = 37°
- O = height of tower (let's call this h)
- A = 220 ft
Substituting these values into the trig tan ratio:
Multiply both sides by 220:
Therefore, the height of the tower is 165.8 ft (nearest tenth)
<span>A circular clock face has a diameter of 7 inches.
What is the area of the clock face?
Round to the nearest tenth.

<span>Each team in the softball league plays each of the other teams exactly once. For every game, there is 2 team playing. The order is not important because A vs B is same as B vs A
So you just need to makes a combination of 2 that have a result of 21. If there is t number of teams, the number of matches would be:
tC2 = t!/2!(t-2)! = 21
</span>t! / (t-2)! = 21 *2
(t)(t-1)= 42
t^2 -t -42=0
(t-7)(t+6)
t=7 ; t=-6
Excluding the minus result, you got 7 teams.
Inverse means 1 over the other so y=1/x, we are given that y=2 when x=5 so our equation turns into 2=/=1/5, these things do not equal so we have to add a coefficient to the right to make this statement true. I would select 10, so that it becomes y=10/x, when the values are plugged in it becomes 2=10/5 or 2=2.
