Answer:
237.65 feet
Step-by-step explanation:
From the diagram attached,
Let the height of the blimp above the ground be h
From triangle A of the diagram,
tan18° = (360-y)/h
h = (360-y)/tan18°..................... Equation 1
Also
From triangle B in the diagram,
tan50° = y/h
h = y/tan50°.............................. Equation 2
Equation equation 1 and equation 2
(360-y)/tan18° = y/tan50°
tan50°(360-y) = tan18°(y)
1.19(360-y) = 0.325(y)
428.4-1.19y = 0.325y
428.4 = 0.325y+1.19y
1.515y = 428.4
y = 428.4/1.515
y = 282.8
Substituting the value of y into equation 2
h = 282.8/tan50°
h = 282.8/1.19
h = 237.65 feet.
Answer:

10.5
Answer:
D:3
Step-by-step explanation:
The missing values are 2.5, 10 and 22.5
<h3>What is equation?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Using equation (y2-y1)/(x2-x1) to find the slope.
Now using two points as (5, 12.5) and (6, 15.00)
So, (15-12.5)/(6-5)
=2.5/1
=2.5
Hence, single ticket costs 2.5
For 2 tickets,
= 2.5×2=5
The cost of two tickets is $5
For 4 tickets,
= 4×2.5=10
The cost of four tickets is $10
For 9 tickets,
= 2.5×9=22.5
The price of nine tickets is $22.5.

Hi there!
So first you need to know that there are 60 seconds in 1 minute.
So 3 and 1/2 minutes would be 3 times 60 seconds plus 30 seconds (1/2 minute is 30 seconds because 60 ÷ 2 = 30) :
<u>(3 × 60)</u> + 30 = Number of seconds
<u>180 + 30</u> = Number of seconds
210 = Number of seconds → ANSWER
There you go! I really hope this helped, if there's anything just let me know! :)
