Answer:
1. If Adam burns 850 calories per hour
850×3=2550 calories for 3 hours
2. If the original price is 200$ and the discount is 30%
We get:
200 × 30
Which can be written as
200×0.3
=60
So 30% of 200 is 60
now to calculate the new price
200-60=140$
The new price is 140$
The answer would be 9.57%. You would move the decimal 2 places to the right and add the percent.<span />

Answer:
Step-by-step explanation:
A right angle triangle is formed.
The length of the guy wire represents the hypotenuse of the right angle triangle.
The height of the antenna represents the opposite side of the right angle triangle.
The distance, h from base of the antenna to the point on the ground to which the antenna is attached represents the adjacent side of the triangle.
To determine h, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Therefore,
41² = 32.8² + h²
1681 = 1075.84 + h²
h² = 1681 - 1075.84 = 605.16
h = √605.16
h = 24.6 m
To determine the angle θ that the wire makes with the ground, we would apply the the cosine trigonometric ratio.
Cos θ = adjacent side/hypotenuse. Therefore,
Cos θ = 24.6/41 = 0.6
θ = Cos^-1(0.6)
θ = 53.1°
