The length of square B is 12 cm.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given that, square A is 3 cm long.
The scale that maps square A onto square B is 1:4.
Let the length of square B be x.
1/4 =3/x
x=4×3
x=12 cm
Therefore, the length of square B is 12 cm.

Theo starts with savings of £18. James starts with no savings.
Each week from now,
Theo will save £4.50 and James will save £4
In how many weeks will Theo and James have savings in the ratio 15:8 ?
(Simple way to work it out please)
Answer:
6 weeks
Step-by-step explanation:
Theo savings = 18 + 4.50x
James = 4x
where x = number of weeks
Theo : James = 15 : 8
18 + 4.50x : 4x = 15 : 8
(18 + 4.50x ) / 4x = 15 / 8
Cross multiply;
8 (18 + 4.50x) = 15 (4x)
144 + 36x = 60x
60x - 36x = 144
24x = 144
x = 144 / 24 = 6 weeks

How do I draw and determine the equation of a trend line on a scatterplot
Step-by-step explanation:
Step 1: Draw your trend line.
You begin by drawing your trend line. You want your trend line to follow your data. You want to have roughly half your data above the line and the other half below the line, like this:
trend line equation
Step 2: Locate two points on the line.
Your next step is to locate two points on the trend line. Look carefully at your trend line and look for two easy to figure out points on the line. Ideally, these are points where the trend line crosses a clearly identifiable location.
For the trend line that we just drew, we can see these two easily identifiable points.
trend line equation
We can easily identify these two points as (3, 3) and (12, 6).
Step 3: Plug these two points into the formula for slope.
The formula for slope is this one:
trend line equation
We can label our first point as (x1,y1), and our second point as (x2,y2). So our x1 is 3, our y1 is 3, our x2 is 12, and our y2 is 6. Plugging these values into the equation for slope and evaluating, we get this:
trend line equation
So our slope is 1/3.

write a short explanation of why the distance formula works and include a discussion of why either point can be point 1 or point 2
Answer:
Finding the distance between two distinct points on a plane is the same as finding the hypotenuse of a right triangle. From this perspective, the distance formula states that the distance of two distinct points on a plane is equal to the square root of the sum of the square of the rise and run.

Solve for x
4 - ( 2x - 2) + 3x = 4(x + 5) - 3(x-2)-10
Step-by-step explanation:
4 + x + 3x = 4 ( 5x ) - 3 ( x ) - 10
4 + x + 3x = 4 + 5x - 3 + x - 10
x + 3x + 5x + x = 4 + 4 - 3 - 10
10x = 21
10x % 10 = 21 % 10
x = 2,1

The ratio of two supplementary angle is 3:1. Find the measures of both angles.
Answer:
The sum of two angle is 180 (supplementary)
given angle = 3:1
first angle =3x
2 nd angle=1x
3x+1x =180
4x =180
x = 180/ 4
x = 45
so first angle =3x x = 45
= 3×45
= 135 degree
2nd angle = 1x
=45 degree
ans
Both angles are 135 and 45

Ms. Johnson owns a cabinet business that installs cabinets in kitchens. Her employees can install 2/3 of a
kitchen cabinet set in 1/5 of an hour.
How many kitchen cabinet sets can be installed by her workers in 1 hour?
Express your answer as an improper fraction.
Answer:
10/3 of the cabinet
Step-by-step explanation:
Given data
We are given that in 1/5 hour they can install 2/3 kitchen cabinet
We want to find out how many of the kitchen cabinet they can install in one hour
Hence
in 1/5 hour they installed 2/3 cabinet
in 1 hour they will install x cabinet
cross multiply
x* 1/5= 2/3
divide both sides by 1/5
x= 2/3/1/5
x= 2/3*5/1
x= 10/3 of the cabinet

1. The length of a rectangle is 4 meters less than
twice its width. The area of the rectangle is
70 m2. Find the dimensions of the rectangle.
Answer:
length is 10, width is 7
Step-by-step explanation:
Area of a rectangle = length * width = lw
Area is known to be 70
length = twice width - 4 = 2w-4 = l
width=w
so A = lw = (2w-4)w = 70
(2w-4)w=70
2w^2-4w=70
2w^2-4w-70=0, divide by 2
w^2 - 2w - 35 = 0, not sure how your class solves these, I see visually
(w-7)(w+5)=0
w=7 or w=-5, -5 makes no sense in the real world (negative length), so w=7
l = 2w-4 = 2(7)-4 = 14-4 = 10
Expand and simplify (x+3)(x-4)
Answer:
Step-by-step explanation:
Use FOIL method.
F - First ; O - Outside ; I - inside ; L - last
(x + 3)(x - 4) = x*x + x*(-4) + 3*x + 3*(-4)
= x² - 4x + 3x - 12
= x² - x - 12
