if XYZ ~ RST, find RS
Answers
Answer:
RS = 38
Step-by-step explanation:
20x - 12 = 18x + 12
2x = 24
x = 12
3(12) + 2 = 38
The value of the side of triangle RS is equal to 38.
What is the similarity?If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the sides of the triangle XYZ are, XY = 5x - 3, XZ = 60 and the sides of the triangle TR = 40, RS = 3x + 2.
The value of RS will be calculated as,
( 5x - 3 ) / ( 3x + 2 ) = ( 60 / 40 )
( 5x - 3 ) / ( 3x + 2 ) = ( 6 / 4 )
20x - 12 = 18x + 12
2x = 24
x = 12
RS = 3x + 2
RS = ( 3 x 12 ) + 2
RS = 36 + 2
RS = 38
Therefore, the value of the side of triangle RS is equal to 38.

A right prism has height 7½ and triangular bases with sides of length 5, 12, and 13 What is the: Total Surface Area of the Prism
Answers
Given:
A right prism has height 7½ and triangular bases with sides of length 5, 12, and 13.
To find:
The total surface area of the prism.
Solution:
We have,
Height of prism = 7½ = 7.5
Sides of triangular base are 5, 12, 13. These sides of Pythagorean triplets because
[tex]5^2+12^2=13^2[/tex]
[tex]25+144=169[/tex]
[tex]169=169[/tex]
So, the base of the prism is a right triangle.
Area of a triangle is
[tex]Area=\dfrac{1}{2}\times base \times height[/tex]
[tex]A_1=\dfrac{1}{2}\times 5\times 12[/tex]
[tex]A_1=30[/tex]
The area of the base is equal to the area of the top, i.e., [tex]A_2=30[/tex] sq units.
Perimeter of the base is
[tex]P=5+12+13[/tex]
[tex]P=30[/tex]
The curved surface area of the prism is
[tex]CSA=\text{Perimeter of the base}\times \text{Height of the prism}[/tex]
[tex]CSA=30\times 7.5[/tex]
[tex]CSA=225[/tex]
Now, the total area of the prism is
[tex]A=A_1+A_2+CSA[/tex]
[tex]A=30+30+225[/tex]
[tex]A=285[/tex]
Therefore, the total surface area of the triangular prism is 285 square units.

Answer:
The area of the shaded portion is 450.185 in^2
Step-by-step explanation:
21^2+20^2=841
The square root of 841 is 29
29+20+21=70
70*1/2=35
35-29=6
35-21=14
35-20=15
The square root of 35*6*14*14=210
The area of the triangle is 210 in^2
The diameter of the circle is 29, so the radius is 14.5
14.25^2=210.25
210.25*3.14=660.185
660.185-210=450.185

9.Set R= {a, b, c}. Find the number of subsets in set R.
(4 Points)
Answers
Given:
The set is:
[tex]R=\{a,b,c\}[/tex]
To find:
The number of subsets in set R.
Solution:
Formula for number of subsets in a set of [tex]n[/tex] elements is
Number of subsets = [tex]2^n[/tex] ...(i)
We have,
[tex]R=\{a,b,c\}[/tex]
Here, the number of elements are 3. Putting [tex]n=3[/tex] in (i), we get
Number of subsets = [tex]2^3[/tex]
= [tex]8[/tex]
Therefore, the number of subsets is 8 and the subsets are [tex]\phi,\{a\},\{b\},\{c\},\{a,b\},\{a,c\},\{b,c\}[/tex] and [tex]\{a, b, c\}[/tex].

Answer:
x = 1, y = 4, or x = -2, y = 1
Step-by-step explanation:
y = -x^2 + 5
-x + y = 3
Use substitution to solve for the equation
-x + (-x^2 + 5) = 3
-x^2 - x + 5 = 3 (simplifying)
-x^2 -x + 2 = 0 (simplifying)
(-x + 1)(x+2) = 0 (factoring)
-x + 1 = 0 or x + 2 = 0
x = 1, or x = -2
-x + y = 3
-(1) + y = 3, or -(-2) + y = 3
y = 4, or y = 1
just choose any one...
x = 1, y = 4
or x = -2, y = 1

Triangle ABC is similar to triangle A'B'C'. Calculate the length of side A'B'. Then check your
answer using a different method.
Answers
Answer:
A'B' = 7.5
Step-by-step explanation:
uhhh
AC = A'C'
4 = 6
×1.5
AB^2 = 4^2 + 3^2
AB^2 = 16 + 9
AB^2 = 25
AB = √25
AB = 5
A'B' = 5 × 1.5 = 7.5
The value of A'B' for the given congruent triangle will be 7.5.
What is congruence?If two figures are exactly the same in sense of their side of all things then they will be congruent.
If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.
As per the given congruent triangle,
In triangle ABC,
AB = √(3² + 4²) = 5
The ratio of the corresponding sides of the two triangles is the same.
A'B'/A'C' = AB/AC
A'B'/6 = 5/4
A'B' = 30/4 = 7.5
Hence "The value of A'B' for the given congruent triangle will be 7.5".

Answers
Answer:
225.08, which would just be 225.
Step-by-step explanation:
First, you multiply the percent, 17, times the total number of points, 1,324, which you should get 22,508. Then, divide that by 100, and you will get your answer 225.08. The reason you put it into the whole number, is because you can't score part of a point, so you always round down even if the number is in favor to round up. I hope this helps :)
