It took a manticore the same amount of time to fly 10 miles with the wind as 5 miles against the wind. What is the speed of the speed of the wind if the manticore flies 30 mph in still air?
Answers
Step-by-step explanation:
The time it takes for the manticore to travel 10 miles with the wind is given by
[tex]T_1 = \dfrac{10\:\text{mi}}{v_m + v_w}[/tex]
where [tex]v_m[/tex] is the speed of the manticore and [tex]v_w[/tex] is the speed of the wind.
Likewise, the time it takes for the manticore to travel 5 miles against the wind is
[tex]T_2 = \dfrac{5\:\text{mi}}{v_m - v_w}[/tex]
Since [tex]T_1 = T_2,[/tex] we can write
[tex]\dfrac{10\:\text{mi}}{v_m + v_w} = \dfrac{5\:\text{mi}}{v_m - v_w}[/tex]
After cross-multiplying,
[tex]10(v_m - v_w) = 5(v_m + v_w)[/tex]
[tex]\Rightarrow 10v_m - 10v_w = 5v_m + 5v_w[/tex]
Collecting similar terms, we get
[tex]15v_w = 5v_m[/tex]
Solving for [tex]v_w,[/tex] we get
[tex]v_w = \dfrac{5}{15}v_m = \dfrac{1}{3}v_m[/tex]
[tex]\:\:\:\:\:\:\:=\dfrac{1}{3}(30\:\text{mi/hr}) = 10\:\text{mi/hr}[/tex]
Speed of the wind as the mantle flies 30 mph is;
10 mph
We know that formula for time is;t = distance/speed
Let v_m be speed of manticore
Let v_w be wind speed
Time for it to fly 10 miles with the wind is;t = 10/(v_m + v_w)
Time for it to fly 5 miles against the wind is;t = 5/(v_m - v_w)
I used negative sign between v_m and v_w because the motion is against the wind.
Since we are told the mantle flies 30 mph in air and the times in both cases are equal, then we have;10/(30 + v_w) = 5/(30 - v_w)
Rearranging gives us;
(10/5)(30 - v_w) = 30 + v_w
2(30 - v_w) = 30 + v_w
60 - 2v_w = 30 + v_w
30 = 3v_w
v_w = 30/3
v_w = 10 mph

Answers
Given : A solid wooden block in the shape of a rectangular prism has a length, width, and height of 3/8 centimeter, 1/8 centimeter, and 5/8 centimeter, respectively.
To Find :The volume of the block
The number of cubic wooden blocks with a side length of 1/8 centimeter that can be cut from the rectangular block .
Solution:
Volume of rectangular prism = length * width * height
= (3/8) ( 1/8) ( 5/8)
= 15/8³
= 15/512
= 0.029296875 cm³
Volume of block = 15/512 cm³ or 0.029296875 cm³
Volume of cube = ( edge length )³
=> cubic wooden blocks volume = (1/8)³ = 1/512 cm³
The number of cubic wooden blocks that can be cut = (15/512) / (1 /512)
= 15
Volume of block = 15/512 cm³ or 0.029296875 cm³
The number of cubic wooden blocks that can be cut = 15
The volume of the wooden block is 5/64 cubic centimeters
How to determine the volume of the wooden block?The given parameters are:
Length = 3/8
Width = 1/8
Height = 5/3
The volume of a rectangular prism is:
Volume = Length * Width * Height
So, we have:
Volume = 3/8 * 1/8 * 5/3
Evaluate the product
Volume = 5/64
Hence, the volume of the wooden block is 5/64 cubic centimeters

Step-by-step explanation:
To find measures of angles m and n
The triangle to the left has three sides of equal length.
This means that it will also have three angles of equal measure.
The internal angles of a triangle sum to 180°
So the internal angles of the left triangle are 180/3 = 60°
The top right angle is made up of one of the 60° angles and angle n
60 + n = 90
n = 30°
Again the internal angles of a triangle sum to 180°, so the right triangle
m + n + 90 = 180
m = 180 - 90 - 30
m = 60°
or we could realize that the top and bottom horizontal lines are parallel because the vertical line on the right makes right angles to both of them.
Knowing that they are parallel, we also know that angle m and the top right 60° angle of the left triangle are opposite internal angles of a line intersecting parallel lines and must be identical angles, therefore
m = 60°

Find the value of x in the isosceles triangle shown below.
Answers
Answer:
B) [tex]x = \sqrt{60}[/tex]
Step-by-step explanation:
1. As you can see from the image, there are two right triangles in the isosceles triangle. The base of each right triangle is 2 (because 4 ÷ 2 = 2), and the hypotenuse is 8.
2. Let's use Pythagorean Theorem to find the height of each right triangle, which will also give us the height of the isosceles triangle: [tex]a^2 + b^2 = c^2[/tex], where a = height, b = base, and c= hypotenuse.
[tex]a^2 + 2^2 = 8^2[/tex] [tex]a^2 + (2*2) = (8*8)[/tex] [tex]a^2 + 4 = 64[/tex] (Simplify both sides of the equation)[tex]a^2 + 4 - 4 = 64 - 4[/tex] (Subtract 4 from both sides)[tex]a^2 = 60[/tex] [tex]\sqrt{a^2} = \sqrt{60}[/tex] (Take square root of both sides[tex]a = \sqrt{60}[/tex]3. The√(60) is the height of each right triangle, and it's also the height of the isosceles triangle. Therefore, the answer is B) x = √60.
