hope you understand. Pls make me in brainliest
Step-by-step explanation:
You can trace a right triangle with these features:
- the 6 feet distance represents the horizontal distance from you to the TV, this is the base of the triangle or the adjacent leg
- the 8 feet distance is the vertical distance from the base of the triangle to the TV, this is the height of the triangle or opposite leg.
- the angle theta that you make with the top of your TV is
tan (theta) = opposite leg / adjacent leg = 8/6 =4/3
=> theta = arctan (4/3) = 53.13 degrees.
Answer: 53.103 degrees
Answer:
101.1%
Step-by-step explanation:
The two batteries are in the shape of cylinder.
The total surface area of a cylinder
SA = (2πr^2 + 2πrh ) =
For AAA battery
h = 0.8mm
r = 1.9 mm
SA = (2π(1.9)^2 + 2π × 1.9 × 0.8 )
SA = 22.68 + 9.55
SA = 32.23 mm^2
For AA battery
h = 1 mm
r = 2.75 mm
SA = (2π(2.75)^2 + 2π×2.75× 1 )
SA = 47.52 + 17.28
SA = 64.80 mm^2
Increase in SA = 64.80 - 32.23
Increase in SA = 32.57
% increase = increase in SA/AAA × 100
% increase in SA = 32.57/32.23 × 100
% increase in SA = 101.1%

Answer:
40+2s=60-3s
Step-by-step explanation:
The red balloon starts 40 feet off the ground and rises 2 feet per second. This means the height of the red ballon is 40+2s.
The blue balloon starts 60 feet off the ground at starts falling 3 feet per second. This means the height of the blue balloon is 60-3s.
Because we want to find out when the balloons will be the same height, we set them equal to each other.
40+2s=60-3s
