Answer:
The 8 bar soap is a better deal.
Step-by-step explanation:
Tamara wants to calculate the height of a tree outside her home. Using her clinometer (angle measuring device) she measures the angle from 35 feet away from the base of the tree and gets an angle of 62 degrees Tamara's eye level is 5.5 feet above the ground.
1. What trigonometric relationship (sine, cosine or tangent) would be used to determine how tall the tree is?
2. Write an equation to determine how tall the tree is, in feet.
3. How tall is the tree, in feet? Round your answer to the nearest tenth.
4. Marcus lives across the street from Tamara Marcus's eye-height is 4.25 feet, and he estimates that he views the top of the tree with an angle of elevation of 50 degrees and is standing 65 feet away from the tree. Are Marcus's estimates reasonable? Explain why or why not.
Answer:
61.922 feet
Step-by-step explanation:
For this problem, we simply want to set up a trigonometric function that computes the height of the tree, and we want to add the height of Tamara.
We are given a distance from the tree of 30 feet with an angle from her eye-level to the top at 62 degrees. So we can say the following:
y = tan(Θ) * x
Where Θ = 62 degrees, x = 30 feet, and y is the height of the tree from Tamara's eye level.
y = tan(Θ) * x
y = tan(62) * 30
y = 56.422
So we also need to include the height of Tamara to get the total height of the tree from the ground to the top.
56.422 ft + 5.5 ft = 61.922 ft
Hence, the total height of the tree is 61.922 feet.
The height of the tree is 71.32 feet.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
We set up a trigonometric function to get height of tree.
Distance ,
x = 35 feet away from tree base
Angle = 62⁰ at eye level
Then we get;
Y = tan(angle) x
Y = tan(62⁰) x 35
Y = 1.881 x 35
Y = 65.82 feet
We add Tamara's height to the total height of the tree that forms an equation as;
= 65.82feet + 5.5 feet
= 71.32 feet is the height of the tree
The height of the tree is 71.32 feet.

ASAP!!! 135 5 - 4 (3x + 31) (7x - 64) (4x + 15) (6x - 8) 120° Q. Solve for X.
Answer:
X=3
Step-by-step explanation:
this is a heptagon (7sides) so all the angles must add to 900 degrees
you have to add them all up
135+(5x-4)+(3x+31)+(4x+15)+(6x-8)+120+(7x-64)=900
25x+225=900
25x+225-225=900
25x=675
25x/25=675/25
x=3
The value of x in the given hexagon is 19.8°.
What is a polygon?A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.
Each line of the polygonal circuit's segments is referred to as its edges or sides.
We know the sum of interior angles in a hexagon is 720°.
∴ 135° + (5x - 4)° + (3x + 31)° + (7x - 64)° + (4x + 15)° + (6x - 8)° + 120° = 720°.
5x + 3x + 7x + 4x + 6x = (720 - 135 + 4 - 31 + 64 - 15 + 8 - 120)°.
25x = 495°.
x = 19.8°.

You purchased concentrated cleaner that must be diluted (watered down) before use. Container A is the cleaner, which is a 20% solution. Container B is pure water. You are mixing together the contents of Container A and Container B to produce 40 gallons of 9% solution. How many gallons from each container are needed to create the 40 gallons of 9% cleaning solution? Write your answers as integers only.
Container A: 20% Cleaning Solution =
gallons
Container B: Pure Water =
gallons
Answer:
Amount of chemical solution = 18 gallon
Amount of pure water = 22 gallon
Step-by-step explanation:
Assume;
20% of solution = x
So,
Amount of pure water = 40 gallons - x
Amount of pure water = 40 - x
Computation:
20% of x = 9% of 40 gallon
0.2 x = 3.6
x = 3.6 / 0.2
x = 18 gallon
So,
Amount of chemical solution = 18 gallon
Amount of pure water = Total solution - Amount of chemical solution
Amount of pure water = 40 -18
Amount of pure water = 22 gallon
