An observatory is 150 feet high. When a person is standing in the observatory looking at an island, the angle of depression is . What is the approximate horizontal distance from the observatory to the island?
A. 70 feet
B. 166 feet
C. 322 feet
D. 355 feet
Answer:
C
Step-by-step explanation:
We want to find the horizontal distance from the observatory to the island, which is adjacent to the known angle.
Because we also know the height of the observatory and is opposite to the angle, we can consider using tangent. Recall that:
[tex]\displaystyle \tan \theta ^\circ = \frac{\text{opposite}}{\text{adjacent}}[/tex]
Let the horizontal distance be x. Substitute in known values:
[tex]\displaystyle \tan 25^\circ = \frac{150}{x}[/tex]
Solve for x:
[tex]\displaystyle x = \frac{150}{\tan 25^\circ}[/tex]
Use a calculator. Hence:
[tex]x\approx 322\text{ feet}[/tex]
In conclusion, our answer is C.

Christian is 1.35 meters tall. At 10 a.m. , he measures the length of a tree’s shadow to be 38.65 meters. He stands 34.4 meters away from the tree, so that the top of his shadow meets the tip of the tree’s shadow. Find the height of the tree to the nearest hundredth of a meter.
The height of Christian and the height of the tree is a ratio likewise the length of Christian shadow and tree shadow. Therefore, the height of the tree to the nearest hundredth is 1.52 meters.
What is Proportion?Proportion is a mathematical comparison between two numbers. it says that two ratios (or fractions) are equal. Therefore,
Christian height = 1.35 m
Tree shadow = 38.65 meter
Christian shadow = 34.4 meters
Let's establish the proportion to find the height of the tree. Therefore,
let
x = height of the tree
1.35 / x = 34.4 / 38.65
cross multiply
38.65 × 1.35 = 34.4x
x = 52.1775 / 34.4
x = 1.5167877907
x = 1.52 meters
Therefore, The height of the tree is 1.52 meters.

The perimeter of a rectangular school yard is 264 meters. The school yard is 89 meters long. How wide is it?
Answer:
43 meters
Step-by-step explanation:
Perimeter is 2l+2w
l equals length
w equals width
264 = 2*89 + 2w
264 = 178 + 2w
264 - 178 = 2w
2w = 86
w = 43

Gerald works at a warehouse that ships products to various grocery stores. He has 230 boxes of oatmeal to ship. If Gerald can place 12 boxes of oatmeal into a crate, what is the minimum number of crates he will need in order to ship every box of oatmeal?
Answer:
20
Step-by-step explanation:
He only can put 12 boxes in 1 crate to ship 230 boxes of oatmeal the least number of crates he can use is 20 because 20 crates would= up to 240 boxes.
He can't do 19 boxes because he is short he would then only have 228 boxes and that is 2 short.
But if he does 20 crates he would be good for what needs and just have 10 more extra.

This is saying he had 20 crates and use x as number of boxes for example each 1 crate could ship x amount of boxes and x is representing 12 boxes per crate and since he has 20 crates what is 20 x 12= x( the number of boxes total(240 boxes)
I hope this helps have a awesome day:)
Answer:
20 crates
Step-by-step explanation:
Since he has 230 boxes and each crate can have up to 12 boxes, we can divide 230 by 12 to see how many crates will be needed:
[tex]\boxed{\frac{230}{12} }[/tex]
Let's do long division to solve this:
we have the equation 230 ÷ 12
__________
12 | 2 3 0
__0_______
12 | 2 3 0

So, as we can see, the quotient is 19 but we have a remainder of 2, which means that, from the 230 boxes, 228 fits into 19 crates and 2 boxes are left. This means that we will need one extra crate to put these 2 boxes.
So, in total, he will need 20 crates.

What is the missing number?
− 2 = 4
OK, the answer is 6, right? Because 6 − 2 = 4. Easy stuff.
Well, in Algebra we don't use blank boxes, we use a letter (usually an x or y, but any letter is fine). So we write:
x − 2 = 4
It is really that simple. The letter (in this case an x) just means "we don't know this yet", and is often called the unknown or the variable.
And when we solve it we write:

A large plastic bucket is in the shape of a right, circular cylinder with dimensions shown below. If there are volume of this cylinder? 1000 cubic centimeters in a liter and 3.785 liters in a gallon, then which of the following is true about the volume of this cylinder?
The volume of the cylinder is between 5 and 6 gallons.
What is the volume of the cylinder?
A cylinder is a three-dimensional shape that is made up of a prism with a circular base.
Volume of a cylinder = nr^2h
Where:
h = heightn = 22/7r = radius22/7 x 28 x (15^2) = 19,800 cubic centimeters
First convert the volume to liters = 19,800 / 1000 = 19.8

if the edge of the circle lies four units directly up from the x-axis what is the length of BC? What is the distance from B to D?
By using what we know about circles and distance between points, we will see that:
BD = 18 units
BC = 16.97 units
What is the distance from B to D?
Remember that the distance between two points (x₁, y₁) and (x₂, y₂) is given by:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
The distance from B to D, will be equal to the distance from B to A, minus the radius of the circle.
Because we know that the center of the circle is at (8, 10), and the edge of the circle is 4 units above the x-axis, we can assume that the closest point on the circle to the x-axis is:
(8, 4)
Then the radius of the circle is given by the distance between these two points:
[tex]r = \sqrt{(8 - 8)^2 + (10 - 4)^2} = 6[/tex]
Now we need to find the distance between A and B.
A = (8, 10)
B = (0, 10 - 16*√2)
The distance between these points is:
[tex]d = \sqrt{(8 - 0)^2 + (10 - 10 + 16*\sqrt{2})^2 } \\\\d = \sqrt{(8)^2 + (16*\sqrt{2})^2 } = 24[/tex]
And the distance from B to D is the distance from B to A, minus the radius of the circle, so we have:
BD = BA - r = 24 - 6 = 18
The distance from B to D is 18 units.
To get the value of BC, we use the fact that this is a cathetus of a right triangle with a hypotenuse of 18 units, and where the other side AC measures 6 units, then we have:
BC^2 + 6^2 = 18^2
BC = √(18^2 - 6^2) = 16.97 units.
