Abigail redecorates her house. A scale drawing of her house can be seen below. if each 6 cm on the scale drawing equals 12 ft, what are the actual dimensions of Abigail's house?
The actual dimensions of Abigail's house are 20ft, 14ft, 18ft, 16ft, 18ft.
For 6 cm in drawing his house is 12 ft on scale which is twice the drawing
This means the scale factor is 2
Therefore,
10cm = 2 × 10 = 20ft
7cm = 2 × 7 = 14ft
9cm = 2 × 9 = 18ft
8cm = 2 × 8 = 16ft
9cm = 2 × 9 = 18ft
What is scale factor?The scale factor is the quantity that is multiplied by an object's scale to produce a separate object that has the same appearance but is a different size—either scaled up or scaled down.
To increase an object by a scale factor, measure all of its sides and multiply the result by the scale factor.

A cafeteria is 6 squared ft wide and 7 squared ft long apply the laws of exponents to write two equivalent expressions for the area of the cafeteria
The two equivalent expressions for the area of the cafeteria are:
a. x = 6² + 7² feet
b. 36 + 49 = x feet.
Given the length of the cafeteria is 7² ft and
the width of the cafeteria is 6² ft.
Area = length × width
let the area be 'x'.
x = 6² × 7²
According to the law of exponents.
x = 36 × 49
x = 1764 ft
hence we get the area as 1764 ft of the cafeteria.

C=59(F−32)
The equation above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured in degrees Celsius. Based on the equation, which of the following must be true?
A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of 59 degree Celsius.A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.A temperature increase of 59 degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.
A) I only
B) II only
C) III only
D) I and II only
Who ever answers this first correctly and show explanation gets brainliest
ANSWER:
d
ANSWER EXPLANATION: Think of the equation as an equation for a line
y=mx+b
where in this case
C=59(F−32)
or
C=59F−59(32)
You can see the slope of the graph is 59, which means that for an increase of 1 degree Fahrenheit, the increase is 59 of 1 degree Celsius.
C=59(F)
C=59(1)=59
Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of 95 degrees Fahrenheit.
C=59(F)
1=59(F)
(F)=95
Since 95 = 1.8, statement II is true.
The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of 59 degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:
C=59(F)
C=59(59)
C=2581(whichis≠1)
An increase of 59 degree Fahrenheit leads to an increase of 2581, not 1 degree, Celsius, and so Statement III is not true.
The final answer is D.
Answer:
D) i and ii
Step-by-step explanation:
from given equation, we can simplify =
1.8 C = F-32 .....................i
F = 1.8 C +32 ....................ii
now, from (i)
1.8 (C+1 ) = 1.8 C + 1.8 = (F +1.8) -3.2
so increasing 1 C equivalent to 1.8 F ........... iii
from iii,
increasing (1/1.8) C or (5/9) C equivalent to (1.8/1.8) F or 1 F
increasing (5/9)/ (5/9) or (25/81) C equivalent to 5/9 degree F
(so given iii become false)
only i and ii is true = D

Subtract it with equation 2 ;
i.e., Equation 3 - Equation 2
(4x + 10y) - (4x + 3y) = 10 - 3
7y = 7

The scale factor of Alana's drawing is 3: 72.
What is the scale factor?You must specify the extent of the shape's enlargement when describing one.
The scale factor is the ratio of two dimensions such that one figure is large and another is small.
The scale factor is done due to the unpractical measurement of any figure.
Dimension in real = 6 feet
Since,
1 feet = 12 inches
6 feet = 72 inches
Dimension in drawing = 3 inches.
Scale factor = Dimension in drawing / Dimension in real
Scale factor = 3/72
Hence "The scale factor of Alana's drawing is 3: 72".

Reflection over the y-axis: (x,y)→(−x,y)
Reflection over the x-axis: (x,y)→(x,−y)
When making a reflection of a triangle and describing it you would need to provide the following two details. First, over which axis the triangle is being reflected over. Secondly, the exact location of each reflected point of the triangle. Doing so would describe how the triangle is being reflected and which point is ending up in which location. Thus, letting the viewer/reader know exactly what is being done to the triangle

Answer:
Because the graph has the parabol shape, so the equation of it has the function:
y = ax² + bx + c
Because the parabol has a peak at point (0; 9)
=> 9 = a.0² + b.0 + c
=> c = 9
=> The parabol has a function:
y = ax² + bx + 9
Because the parabol goes through point (3; 0)
=> 0 = a.3² + b.3 + 9
=> 9a + 3b = - 9 (1)
Because the parabol goes through point (-3; 0)
=> 0 = a.(- 3)² + b.(- 3) + 9
=> 9a - 3b = - 9 (2)
Plus (1) and (2):
=> 18.a = - 18
=> a = - 1
Substitute the result on (1)
=> b = 0
=> The function of the parabol: y = - x² + 9
=> a = - 1
=> Choose A. - 1

If mary wants to bake muffins .she she has 3kg of flour. if a tray of 6 muffins 200g of of flour how many trays will she bake
Mary will bake 15 trays.
Firstly converting the amount of flour into grams that Mary has.
As per the known facts 1 kilogram = 1000 grams.
So, amount of flour in grams = 3 × 1000
Performing multiplication to calculate amount of flour
Amount of flour in grams = 3000 grams.
Now, 200 grams flour is required by number of trays = 1
So, 3000 grams flour will be required by number of trays = (1÷200)×3000
Performing multiplication and division to find the number of trays that can be baked
Number of trays = 15
Hence, Mary can bake 15 trays of muffins with 3 kilograms of flour.

M(5, 7) is the midpoint of PS The coordinates of S are (6, 9). What are the coordinates of p2
The required coordinate of point p is (4,6) of line segment PS.
Given that
M(5, 7) is the midpoint of PS The coordinates of S are (6, 9).
To determine the coordinates of p.
Here,
Let the coordinate of P be (h, k)
Now, the coordinates of the midpoint is given by,
x = [x₁ + x₂] / 2 ; y = [y₁ + y₂] / 2
now, putting x = 5, x₁ = 6, x₂ = h; y = 7, y₁ = 9 y₂ = k
5 = 6 + h / 2 ; 7 = 9 + k / 2
10 - 6 = h ; 14 - 9 = k
h = 4 ; k = 5
