What is the value of m in this proportion?
1/2/3/5=13m
(they are all one big fraction)
Enter your answer as a fraction in simplest form in the box.
The value of m in the proportion is 5/78.
What is proportion?
The size, number, or amount of one thing or group as compared to the size, number, or amount of another. The proportion of boys to girls in our class is three to one.
To solve for m in the proportion:
1/2/3/5 = 13m
We can simplify the left-hand side of the equation by multiplying the first fraction by the reciprocal of the second fraction, and multiplying the third fraction by the reciprocal of the fourth fraction. This gives:
(1/2) ÷ (3/5) = 13m
(1/2) × (5/3) = 13m (using the rule a/b ÷ c/d = a/b × d/c)
5/6 = 13m
To isolate m, we can divide both sides of the equation by 13:
5/6 ÷ 13 = m
m = 5/78
Therefore, the value of m in the proportion is 5/78.

A right angle has a greater measure than a(n) blank angle and a lesser measure than a(n) blank angle
Answer:
Step-by-step explanation:
The angle measure of a right angle is 90 degrees.
Acute angles are angles with measures less than 90 degrees.
Obtuse angles are angles with measures more than 90 degrees.
So,
A right angle has a greater measure than a(n) acute angle and a lesser measure than a(n) obtuse angle

A 6-pack of dish towels costs $21.36. What is the unit price?
Answer:
$3.56
Step-by-step explanation:
Divide 21.36 by 6 and you get 3.56
Answer:
d = $3.56
Step-by-step explanation:
d = the cost of each towel
6d = 21.36
/6 /6
d = $3.56
Check your answer:
6d = 21.36
6(3.56) = 21.36

Answer:
Pudge sold 8 tickets, Christi sold 19
tickets, Ace sold 38 tickets
Step-by-step explanation:
x = Pudge
3x - 5 Christi
2(3x-5) = Ace
Let x, 3x - 5 and 2(3x-5) be the tickets
x + (3x- 5) +2(3x - 5) = 65
Combine like terms
x+ (3x - 5) + 6x - 10 = 65
4x -5+6x - 10 = 65
10x - 5-10 = 65
Transpose -5 and -10 and change their
signs
10x = 65 +5+ 10
Add
10x = 80
Divide both sides by 10
10x/10x = 80/10
x =8
Pudge sold 8 tickets.
Evaluate x as 8

Ace sold 38 tickets.
Checking:
x+ (3x - 5) +2(3x - 5) = 65
8+(3(8)-5) +2(3(8) - 5) = 65
8 +19 +38 = 65

Please find the perimeter and area of these shapes
Answer:
ABC shaded area = 36[tex]\pi[/tex] - 72 cm²
ABC shaded area perimeter = [tex]6\pi +12\sqrt{2}[/tex] cm
ABCD area = [tex]\dfrac52 \pi[/tex] cm²
ABCD perimeter = [tex]3\pi +2[/tex] cm
Step-by-step explanation:
Shape ABC
Assuming you want the area and perimeter of the shaded part of the shape only...
Area
Area of a sector = [tex]\dfrac12r^2\theta[/tex] (where r is the radius and [tex]\theta[/tex]
⇒ area of a sector = [tex]\dfrac12 \times 12^2\times \dfrac{\pi}{2} =36\pi \ \textsf{cm}^2[/tex]
Area of triangle = 1/2 x base x height
⇒ area of triangle = 1/2 x 12 x 12 = 72 cm²
Therefore, area of shaded area = area of sector - area of triangle
⇒ area = 36[tex]\pi[/tex] - 72 cm²
Perimeter
Arc length = [tex]r\theta[/tex] (where r is the radius and [tex]\theta[/tex]
⇒ arc length = [tex]12\times\dfrac12\pi =6\pi \ \textsf{cm}[/tex]
Hypotenuse of triangle = [tex]\sqrt{a^2+b^2}[/tex] (where a and b are the legs of the right triangle)
⇒ hypotenuse = [tex]\sqrt{12^2+12^2} =12\sqrt{2}[/tex] cm
Therefore, perimeter = arc length + hypotenuse
⇒ perimeter = [tex]6\pi +12\sqrt{2}[/tex] cm
Shape ABCD
Area
Area of a semicircle = [tex]\dfrac12 \pi r^2[/tex] (where r is the radius)
⇒ area of large semicircle ABC = [tex]\dfrac12 \times \pi \times 2^2=2\pi \ \textsf{cm}^2[/tex]
⇒ area of small semicircle AD = [tex]\dfrac12 \times \pi \times 1^2=\dfrac12\pi \ \textsf{cm}^2[/tex]
⇒ area of shape ABCD = [tex]\dfrac12 \pi + 2 \pi=\dfrac52 \pi \ \textsf{cm}^2[/tex]
Perimeter
1/2 circumference = [tex]\pi r[/tex]
⇒ perimeter = [tex]2\pi +2+\pi=3 \pi+2 \ \textsf{cm}[/tex]

The altitude to the hypotenuse of a right triangle bisects the hypotenuse. How does the length of the altitude compare with the length of the segments of the hypotenuse. Explain completely. Use Geogebra to help you set up a diagram and show evidence that supports your conclusion.
*Search up Geogebra and take a pic of your triangle*
And explain and show evidence that supports your conclusion.
Any questions please feel free, I will answer your questions.
[tex] \frac{1}{2}[/tex]will be the answer.
Step-by-step explanation:-
If the altitude to the hypotenuse of a right-angled triangle bisects the hypotenuse, then we can know that the triangle is Isosceles right triangle. (AB=AC)
Make AB=AC=2, so,
BC=[tex] \sqrt{ {2}^{2} + {2}^{2} } [/tex]= [tex] \sqrt{4 + 4} [/tex]= [tex] \sqrt{8} [/tex]
Prime factorizing, we get,
BC = [tex] \sqrt{2 \times 2 \times 2} [/tex]
Take two 2's outside by taking common because of "square" root,
⇢BC = [tex]2 \sqrt{2} [/tex]
BD = DC = [tex] \sqrt{2} [/tex],
AD = [tex] \sqrt{AB^{2} - BD^{2} } [/tex]= [tex] \sqrt{4 - 2} [/tex]= [tex] \sqrt{2} [/tex]
So, AD=BD=CD= [tex] \frac{1}{2}[/tex]BC
∴⇢[tex] \frac{AD}{BC} = \frac{1}{2} [/tex]

Answer:
it would actually be 52
Step-by-step explanation:

Below are two regular polygons. Calculate the value of angle a. a a
Answer:
12°
Step-by-step explanation:
The outer polygon is a hexagon and the inner polygon is a pentagon.
Let's start by finding the measure of an interior angle of the (regular) hexagon.
The sum of the measures in a polygon is:
(n-2)(180)
Where n represents the amount of sides in a figure therefore...
(6-2)(180)=4(180)=720
Then, we divide 720 by 6 (because there are 6 angles), to find the measure of one angle...
720/6=120
Next, find the measure of an interior angles of a (regular) pentagon.
(n-2)(180)=(5-2)(180)=3(180)=540
Divide 540 by 5 (there are 5 angles), to find the measure of one angle...
540/5=108
Now, subtract 120 by 108 to find a...
120-108=12
a=12°
