In the diagram below, segments RS and RT intersect line m at points T and S, respectively.
Which of these statements is true?
Triangle RST is an isosceles triangle.
Triangle RST is a scalene triangle.
Triangle RST is a right triangle.
Triangle RST is an equilateral triangle.
Answers
Answer:
RST is an isosceles triangle
Step-by-step explanation:.
Required
Determine what type of triangle, is RST.
First, we need to determine the angles in RST
Angle on a straight line is 180°.
So, if <mTS = 130°
Then,
<STR = 180° - 130°
<STR = 50°
Similarly,
<TSR = 180° - 130°
<TSR = 50°
The sum of angles in a triangle is 180°.
So:
<TSR + <STR + <TRS = 180°
50 + 50 + <TSR = 180°
100 + <TSR = 180°
<TSR = 180° - 100°
<TSR = 80°
Hence, the three angles of the triangle are: 50°, 50° and 80°
When just two angles of a triangle are equal; such triangle is referred to as an isosceles triangle
Hence, option A answers the question.

A hardware store sells power pack A, consisting of 4 D cells and 2 C cells for $12.60, and power pack B, consisting of 6 D cells and 4 C cells for $20.80. What is the price of each cell?
Answers
Answer:
The D cells are worth $2.20, and the C cells are worth $1.90.
Step-by-step explanation:
This can be written as:
4x + 2y = 12.60
6x + 4y =20.80
Our goal is to find one variable, then use that information to find the other.
If we multiply the top function by -1.5, we get:
-6x - 3y = -18.90
We can add this to the previous equation.
-6x - 3y = -18.90
+ 6x + 4y = 20.80
--------------------------
y = 1.90
The C cells are worth $1.90.
Plug this value into one of the other equations and solve for x.
4x + 2y = 12.60
4x + 2(1.90) = 12.60
4x + 3.80 = 12.60
4x = 8.80
x = 2.20
The D cells are worth $2.20.
Check these values in the other equation.
6x + 4y = 20.80
6(2.20) + 4(1.90) = 20.80
13.20 + 7.60 = 20.80
20.80 = 20.80
Answer:
C = $1.90 each
D = $2.20 each
Step-by-step explanation:
Given:
Power pack A: 4D + 2C = 12.60
Power pack B: 6D + 4C = 20.80
Isolate any one variable:
4D + 2C = 12.60
4D = 12.60 - 2C
D = 3.15 - 0.5C
Substitution to find cost of C cell battery:
6D + 4C = 20.80
6(3.15 - 0.5C) + 4C = 20.80
18.9 - 3C + 4C = 20.80
18.9 + C = 20.80
C = 1.90
Substitution to find cost of D cell battery:
4D + 2C = 12.60
4D + 2(1.90) = 12.60
4D + 3.8 = 12.60
4D = 8.8
D = 2.20

Answers
what i got -

how i got it -
Number of floor seats tickets sold = x
Number of balcony seats tickets sold = y
Cost of floor tickets = $15
Cost of balcony tickets = $12
They want to make at least $3,000 in ticket sales.
At least in inequality means ≥
The inequality that represent the situation is 15x + 12y ≥ 3000

A company paid $ 391 for 15 bushes and 8 bonsai trees . They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 . What is the cost of each bush and bonsai tree ? the boxes below .
Answers
Answer:
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
Step-by-step explanation:
Let Cost of one bush = x
Cost of one bonsai tree = y
From the expression: A company paid $ 391 for 15 bushes and 8 bonsai trees
We made equation: [tex]15x+8y=391[/tex]
and From the expression: They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 , we made equation: [tex]9x+5y=241[/tex]
Solving both equations simultaneously we can find value of x and y
Let:
[tex]15x+8y=391--eq(1)\\9x+5y=241--eq(2)[/tex]
We will use elimination method to solve these equations.
Multiply eq(1) by 5 and eq(2) by 8 and subtract
[tex]75x+49y=1955\\72x+40y=1928\\- \ \ \ - \ \ \ \ \ \ \ -\\--------\\3x=27\\x=\frac{27}{3}\\x=9[/tex]
So, value of x=9
Now finding value of y by putting value of x in equation 1
[tex]15x+8y=391\\Put \ x=9\\15(9)+8y=391\\135+8y=391\\8y=391-135\\8y=256\\y=\frac{256}{8}\\y=32[/tex]
So, value of y=32
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
