Find the coordinates of the point on the directed segment from (1,2) to (6,12) that divides it into a ratio of 2:3
Answer:
Point of contact ( 3,6)
Step-by-step explanation:
Step(i):-
Given that the points are (1,2) and (6,12)
The ratio 2:3 divides the line segment
The line segment divides m:n externally
[tex](\frac{mx_{2}-nx_{1} }{m-n} ,\frac{mx_{2}-nx_{1} }{m-n} )[/tex]
Step(ii):-
(x₁, y₁) = (1,2) and (x₂, y₂)= (6,12) and m:n =2:3
[tex](\frac{2(6)+3(1) }{2+3} ,\frac{2(12)+3(2) }{2+3} )[/tex]
([tex](\frac{12+3}{5} ,\frac{24+6}{5} )[/tex]
([tex]\frac{15}{5} ,\frac{30}{5})[/tex]

Given RTSU is a rectangle. If RZ = 3x+8 and ZS = 6x-28, then what does UZ equal?
Answer:
UZ = 44
Step-by-step explanation:
3x+8 = 6x-28
36 = 3x
12 = x
UZ = 3(12)+8
UZ = 44
Answer:
I think UZ would be the same as ZS, so 6x - 28

△XYZ is translated up 3 units to form the image ∆X′Y′Z′.
What are the coordinates of the vertices of ∆X′Y′Z′ ?
Enter your answer by filling in the boxes.
Answer:
The coordinates of the vertices of ∆X′Y′Z′:
X'(-4, 9)Y'(1, 9)Z'(1, 4)Step-by-step explanation:
Given the triangle △XYZ with the vertices
X(-4, 6)Y(1, 6)Z(1, 1)It is stated that △XYZ is translated up 3 units to form the image ∆X′Y′Z′.
Translating 3 units UP means we have to add 3 units to all the y-coordinates of the coordinates of the vertices X, Y, and Z to generate the image ∆X′Y′Z′.
Thus,
THE RULE OF TRANSLATING 3 UNITS UP:
P(x, y) → P'(x, y+3)
Therefore, the coordinates of the vertices of ∆X′Y′Z′ will be:
X(-4, 6) → X'(-4, 6+3) → X'(-4, 9)
Y(1, 6) → Y'(1, 6+3) → Y'(1, 9)
Z(1, 1) → Z'(1, 1+3) → Z'(1, 4)
Thus, the coordinates of the vertices of ∆X′Y′Z′:

Theodore and Sarah have a small business selling custom-made T-shirts. They currently sell 205 shirts per month and charge $15 per T-shirt. Sarah thinks they can increase their revenue by increasing their selling price, but Theodore knows from experience that each $1 increase in price will decrease the number of T-shirts they sell by 9 shirts per month. Find an expression for the total monthly revenue Theodore and Sarah's business can generate if they change the selling price of their T-shirts. Let x represent the number of $1 increases in the price of the T-shirts.
Answer:
(205-9x) times15
Step-by-step explanation:
The expression the total monthly revenue of Theodore and Sarah's business is (205-9x)15.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
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.

find out how much 1kg will cost in the supermarket and multiply by 12.5kg
For the supermarket
1.83/2.5= 0.732 for one kg.
for 12.5 kg
0.732× 12.5= £9.15
hence the farm shop price is lower than the supermarket price
What is the image of the point (3,2)(3,2) after a rotation of 90^{\circ}90 ∘ counterclockwise about the origin?
Answer: = (-2,3)
Step-by-step explanation:
Rotation is a transformation of a figure by rotating it for a specific angle about a fixed point.Here, fixed point = origin = (0,0)
Transformation rule for rotation of [tex]90^{\circ}[/tex]counterclockwise about the origin:
[tex](x,y)\to (-y,x)[/tex]
Then, the image of the point (3,2) = (-2,3)
Hence, the image of the point (3,2) after a rotation of [tex]90^{\circ}[/tex]counterclockwise about the origin = (-2,3)
Answer: The answer is -2,3 because 90 degrees of the orgin :) enjoy

The price of gas was $2.49 last month. This month, gas costs $2.79. What is
the percent increase?
Answer:
12%
Step-by-step explanation:
2.79 - 2.49 = $0.30
0.30 / 2.49 = 0.12 = 12% (decimal changes to percent)
You can check your work by doing original cost times the decimal of the percent increase. $2.49 * 0.12 = $0.30. Add this to original -> 0.30 + 2.49 = $2.79.

c
b>a
a
Answer:
b
Step-by-step explanation:
According to the given angles in the question, angle b is greater than angle a.
What is inequality?Mathematical equations with inequalities on both sides are known as inequalities. In an inequality, we compare these two values as opposed to equations. Somewhere between, the equal sign is changed to a less than (or less than or similar to), bigger than (or greater or equal to), or just not equal to sign.
As per the given data from the question,
The side which has got a larger angle has the largest side.
The side c is greater than a and side b is also greater than a.
The remaining angle can be calculated as:
The sum of all angles will be equal to 360.
x + 75 + 90 + 105 = 360
x = 90°.
