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°

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:
Multiply the numerator by the reciprocal of the denominator.

= 56
How do you convert a fraction into percentage?To write the fraction as the % we 1st need to write it as a fraction out of 100.We write the fraction out of 100 by using equivalent fractions.This means that we must multiply numerator. The number on above of the fraction.We can 1st multiply the top or bottom of the fraction 4 / 5 by 2.
Any number can be converted to fraction if you use one for the denominator:
84/1
Therefore now that we've converted 84 into the fraction, to work out the lowest term, we put the fraction 2/3 side by side with our new fraction, 84/1 so that we should multiply those 2 fractions.
all you need to do is convert the whole number into the fraction or then multiply the numerators or denominators :
2 x 84 / 3 x 1
= 168 / 3
In this situation, our new fraction shall actually be the simplified down further. To do that, we want to find the greatest common factor of those numbers.
We can now sum both the new numerator or the denominator by the three to simplify this fraction down to its lowest terms.
168/3 = 56
3/3 = 1
When we put that together, we could see that our complete solution is:
56/1
= 56

If an angle cuts out an arc length of a circle AND the arc length is SHORTER than the
radius, what is true about the angle?
it is less than pi radians
it equals pi radians
it is greater than pi radians
We want to study the angle of an arc given that the length of the said arc is smaller than the radius of the circle.
The correct option is:
"it is less than pi radians"
A circle of radius R has a circumference:
C = 2*pi*R
An arc defined by an angle θ has a length:
L = θ*R
Now, we know that the length of the arc is smaller than the radius, then we have:
θ*R < R
Dividing both sides by R we get:
θ < 1
So we can see that the correct option is:
"it is less than pi radians"
Because it is smaller than 1.

Describe or show how to find the following product using both an algorithm and a diagram:1/4×2/3
An algorithm is the series of steps followed to do calculations especially by a computer.
[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{3}[/tex] = [tex]\frac{2}{12}[/tex] =[tex]\frac{1}{6}[/tex]
The algorithm would use the multiplication of the numerator with the numerator and the denominator with the denominator for solving simple multiplication of the proper fractions.
[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{3}[/tex]
= (1×2)/(4×3) ⇒ the numerators are multiplied and so the denominators
= 2/12
Now 2 is taken as common from both 2 and 12 ( numerator and denominator)
= (2/2 ) 1/6 taking 2 as common factor
= 1/6 cancelling 2 by 2
The diagram can be used to explain the same fact.
1 is multiplied with 2 and 4 is multiplied with 3.
Therefore we get 2 as numerator and 12 as denominator.

You have a choice between going to an in-state college where you would pay $3000 per year for tuition and an out-of-state college where the tuition is $6500 per year. The cost of living is much higher at the in-state college, where you can expect to pay $1000 per month in rent, compared to $450 per month at the other college. Assuming all other factors are equal, which is the less expensive choice on an annual (12-month) basis?
Answer:
The less expensive choice is the out-of-state college
Step-by-step explanation:
in-state-college: 1000(12)+3000=15000
out-of-state-college:450(12)+6500=11900
The figure below has a point marked with a large dot.
First, rotate the figure 270° clockwise about the origin.
Then, give the coordinates of the marked point in the original figure and the final figure.
Answer:
( 5 , - 3 ) -------> ( 3 , 5 )
Step-by-step explanation:
After the rotation of 270° clockwise about the origin, the coordinate will become (3, - 5).
What is image rotation?A rotation is a type of transformation which is a turn.A figure can be turned clockwise or counterclockwise on the coordinate plane.In both transformations the size and shape of the figure stays exactly the same.Given is a figure rotated 270° clockwise about the origin.
The algebraic rule for a figure that is rotated 270° clockwise about the origin is -
(x, y) → (y, -x)
Initial point marked on the figure : (5, 3)
After the rotation, the points will be : (3, - 5)
Therefore, after the rotation of 270° clockwise about the origin, the coordinate will become (3, - 5).

S=4LW+2WH; S =138, L = 9, W = 3
Step-by-step explanation:
Given,
S = 4LW + 2WH
S = 138
L = 9
W = 3
so value of H,
→ 138 = 2(9)(3) + 2(3)H
→ 138 = 54 +6H
→ 6H = 138 - 54 = 84
→ H = 84/6 = 14
therefore, value of H is 14.

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?
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
