Do these side lengths make a right triangle? 5, 12, 13
Answer:
This is a right triangle
Step-by-step explanation:
We will use the Pythagorean theorem
a^2 + b^2 = c^2
If this is true it is a right triangle
5^2 + 12^2 = 13^2
25+144 = 169
169 =169
This is true so this is a right triangle

the number of sides of a regular polygon whose interior angle is 140
Answer:
9 sides
Step-by-step explanation:
Two methods and the same answer = 9 sides
Method 1: Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.
Method 2: Since the exterior angle 140 degrees, The sum of the interior angles = (2n - 4)* right angles. So 140n =(2n - 4)* right angles, or
140n =(2n - 4)*90, or
140n = 180n - 360, or
40n = 360, or
n = 9 sides.
Hence the number of sides is 9 sides.
Answer:
9
Step-by-step explanation:
The sum of the interior angle and the exterior angle = 180°
Thus the exterior angle of the polygon = 180° - 140° = 40°
The sum of the exterior angles of a polygon = 360°, thus
number of sides = 360° ÷ 40° = 9

What is the slope-intercept equation of the line below?
Answer:
The slope-intercept form:
[tex]y = -3x +4[/tex]
Step-by-step explanation:
-To get the slope-intercept equation, you first need to find the slope by using this equation [tex]m = \frac{rise}{run}[/tex] (starting counting from the first point, to the second point) in order to get the slope. After you have the slope, you need to find the y-intercept ( y-intercept is where the line crosses the y axis of the graph, basically). So, to find that, you need look for the point that only crosses the y axis to get the y-intercept. After you have both the slope and y-intercept, you put it in slope-intercept form:
The two points I found from the following graph are:
[tex]( 1, 1)[/tex] and [tex](2, -2)[/tex]
Trick: Since the line of the graph shows that it is down (not up), Start counting down from point [tex]( 1, 1)[/tex] to point [tex](2, -2)[/tex]. Then, find the y-intercept:
[tex]m = \frac{-3}{1} = -3[/tex]
[tex]b = 4[/tex]
Use it to create a slope-intercept form:
[tex]y = mx +b[/tex] (where [tex]m[/tex] represents the slope and [tex]b[/tex] represents the y-intercept)
[tex]y = -3x +4[/tex]
So, therefore the slope-intercept form is [tex]y = -3x +4[/tex] .

Tim tiene 39 pares de audífonos y 13 reproductores de música. Tim quiere vender todos los audífonos y los reproductores de música en paquetes idénticos. ¿Cuál es el mayor número de paquetes que Tim puede hacer?
Answer: 13 packages.
Step-by-step explanation:
This can be translated to:
Tim has 39 pairs of headphones and 13 music players. Tim wants to sell all the headphones and music players in identical packages. What is the largest number of packages that Tim can do?
To solve this we must find the largest common factor between 39 and 13.
to do this, we divide the smaller number by different integers, and see if the result also divides the larger number into an integer.
13/1 =13 and 39/13 = 3
So 13 is the largest common factor.
This means that we can make 13 packages, each with:
39/13= 3 headphones
13/13 = 1 music players

Match each area of a circle to its corresponding radius or diameter. area: 63.585 square meters area: 28.26 square meters area: 120.7016 square meters area: 12.56 square meters area: 482.8064 square meters area: 113.04 square meters diameter: 12.4 meters radius: 4.5 meters diameter: 6 meters radius: 2 meters
Answer:
Step-by-step explanation:
area = pi*radius*radius -> Radius = [tex]\sqrt{\frac{area}{pi} }[/tex]
area: 63.585 m2
-> radius = [tex]\sqrt{\frac{63.585}{3.14} }[/tex] = 4.5 m
area: 28.26m2
-> radius = [tex]\sqrt{\frac{28.26}{3.14} }[/tex] = 3m
-> diameter = 6m
area: 120.7016m2
-> radius = [tex]\sqrt{\frac{120.7016}{3.14} }[/tex] = 6.2m
-> diameter = 12.4m
area: 12.56m2
-> radius = [tex]\sqrt{\frac{12.56}{3.14} }[/tex] = 2m
area: 482.8064m2
->radius = [tex]\sqrt{\frac{482.8064}{3.14} }[/tex] = 12.4m

Step 1) Divide the figure into shapes
Triangle: 9 x 10
Large rectangle: 8 x 17
Small rectangle: 5 x 9
Smaller rectangle (bottom): 4 x 6
Step 2) Find the area of each shape
Triangle: A = 1/2 x 9 x 10 = 45
Large rectangle: A = 8 x 17 = 136
Small rectangle: A = 5 x 9 = 45
Smaller rectangle (bottom): A = 4 x 6 = 24
Step 3) Add the areas together
A = 45 + 136 + 45 + 24 = 250 square kilometers
Hope this helps! :)

Jina sold t-shirts at a festival. She made $3 for each t-shirt she sold. Her expenses were $27. If she made a profit of $51, how many t-shirts did she sell?
Answer:3x+27=51
27-27=0
51-37=x
X=14
Step-by-step explanation:
Per shirt would be the “x” part of the equation. Meaning 3x would be the cost per shirt. And if her total 51, and it were to be a profit, you would add $27 to 3x.

A $1.50 per Sound
B. $2.00 per pound
C. $2.50 per pound
D. $3.00 per pound
Answer:
$1.50 per pound
Step-by-step explanation:
got same question and got it right.
The cost per pound of apples is given as $1.50 per pound.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
From the table,
Let the cost of the apples is directly proportional to the pound of x apples,
y = kx
Where k represents the cost of each pound of apply,
From the table consider an ordered pair,
x = 2, y = 3
Now,
3 = 2k
k = 3 / 2
k = 1.5
Thus, the cost per pound of apples is given as $1.50 per pound.

which classification best represents a triangle with a side lengths 6 cm,10 cm, and 12 cm ?
Answer:
It would be an obtuse scalene triangle.
EDITED TO ADD:
When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:
1) Square all 3 sides.
2) Sum the squares of the 2 shortest sides.
3) Compare this sum to the square of the 3rd side.
if sum > 3rd side² Acute Triangle
if sum = 3rd side² Right Triangle
if sum < 3rd side² Obtuse Triangle

a secant and tangent are drawn to a circle from a common exterior point. If the length is 14 inches and the length of the external segment of the secant is 4 inches, then it which of the following is the length,in inches, of the internal segment of the secant?
Answer:
Correct option: (3) 45
Step-by-step explanation:
Let's call the length of the tangent 'T', the length of the external segment 'E' and the length of the internal segment 'A'.
If we have a secant and a tangent to a circle, we can use the following property:
T^2 = E * (A + E)
If the tangent is 14 inches and the external segment is 4 inches, we have that:
14^2 = 4 * (A + 4)
196 = 4A + 16
4A = 180
A = 45
Correct option: (3)
