Answer:
A) 7.24 hours
Step-by-step explanation:
The together rate is the sum of each separate rate.
In this problem:
Beth's rate is 1/15(suppose there was a small typing mistake there, with 151 none of the options are correct).
Mike's rate is 1/14
The together rate is 1/x
Then
We want to find x.
15*14 = 210. So
Cross multiplication
So the correct answer is:
A) 7.24 hours
The angle of elevation is = 70° and the distance the airplane travelled in the air is = 17,557ft
<h3>Calculation of the distance travelled</h3>
- To calculate the angle of elevation of the airplane
tan x° = opposite/adjacent
where opposite = 16,500 feet
adjacent = 6,000 ft
tan x° = 16,500 / 6,000
tan x° = 2.75
X = arctan ( 2.75)
X = 70°
- To calculate the distance the airplane travelled in the air Pythagorean Theorem is used.
C² = a² + b²
C² = 16,500² + 6,000²
C² = 272250000 + 36000000
C² = 308250000
C= √308250000
C= 17,557ft

C = (10/2)^2 = 25 to make this the square (x +5)^2.
Answer:
c=3
Step-by-step explanation:
a+b=c
a is double the value of b, so if a is 2, then b is 1.
2+1=3
