Answer:
X = 33,669.78 ft
Y = 15285.76 ft
Step-by-step explanation:
Given data:
let x be the distance btwn arch and plane
and y be the distance btwn ground point and arch y
we know that


xcos27 = 30000

x = 33,669.78 ft
b) we knwo that


y = tan(27) (30000)
y = 15285.76 ft
Answer:
equation: a/.5b=h
h=9
Step-by-step explanation:
a=1/2bh
divide both sides by 1/2b to get h alone
a/.5b=h
a/.5b=h
54/0.5(12)=h
54/6=h
9=h
Answer:
Answer C is correct
Step-by-step explanation:
-200(3/4) = -600/4 = -150 ft
Answer:
2.69 x 
Step-by-step explanation:
We are given the heart's speed - 70 bpm
We count the number of minutes in 73 years :
- 1 year = 365 days
- 1 day = 24 hours
- 1 hour = 60 minutes
- 73 x 365 x 24 x 60 = 38,368,800 minutes
We multiply the heart's bpm with 73 years worth of minutes
38,368,800 x 70 = 2,685,816,000
Write the number in scientific notation = 2.68581 x
≈ 2.69 x
