Answer:
Equation: P(w) = 4w + 8
Step-by-step explanation:
The step is zero. That and being told that the relationship is linear.
The general equation is P(w) = mw + y intercept.
When w = 0 then P(w) = 8
The only way that can happen is when P(w) = 0 + y intercept
y intercept = 8 because P(w) = 8
So far what we have is P(W) = mx + 8 So you are starting with 8 rats.
Now suppose w = 2. The number of rats P(2) that you get is 16
So you are solving for m.
16 = m*2 + 8 Subtract 8 from both sides
16 - 8 = 2*m + 8 - 8 Combine
8 = 2m Divide by 2
8/2 = 2m/2
m = 4

Find the radius of the cone.
Answers
Answer:
Radius = 6
Step-by-step explanation:
The volume of a cone is V= pi*r^2*h/3
In this case, h=18 in.
Volume= 216pi in^3
So all you need to do is plug in and solve.
216pi = pi*r^2 *6
36=r^2
r=6
Radius of cone is 6 in.
What is cone?A cone is a shape created by connecting all the points of a circular base (which does not contain the apex) to a common point known as the apex or vertex using a series of line segments or lines.
Given that;
Volume of cone = 216π in³
Height = 18 in
Since we know that,
The volume of a cone is V= πr²h/3
Therefore plug the values,
⇒216π = πr²(18)/3
⇒ 36 = r²
⇒ r = 6 in

The area of a bulletin board is 90 ft. The length is nine feet less than four times the width. Find the length and the width, in feet, of the bulletin board.
width
ft
length
ft
+
Answers
Width = x
Length = 4x - 9
A = L*W, so the equation is:
x(4x - 9) = 90
Solve:
4x^2 - 9x = 90
4x^2 - 9x - 90 = 0
(4x + 15)(x - 6) = 0
4x + 15 = 0
4x = - 15
x = -15/4
^^^ reject because distance can’t be negative
x - 6 = 0
x = 6 ft (width)
Length = 4x - 9
L = 4(6) - 9
L = 24 - 9
L = 15 ft
Check:
A = L*W
90 = 15 * 6
90 = 90
Answer: The length is 15 feet and the width is 6 feet.

The length and breadth of the plot in metres are in the ratio 10:3.The perimeter
of the plot is 312 m.
Answers
Answer:
I hope this could be of good assistant
Step-by-step explanation:
L:B = 10:3
make L subject of formula
L = 10B/3
perimeter = 312
2( L + B ) = 312
L + B = 312/2
L + B = 156
10B/3 + B = 156
multiply all through by 3
10B + 3B = 156 X 3
10B + 3B = 468
13B = 468
B = 468/13 = 36
B = 36m
L = 10B/3
L = 10 X 36/3
L = 10 X 12 = 120m
L = 120m
Hence if your were asked to find the area
L X B
120 X 36 = 4320m²

Answers
Answer: 41
Step-by-step explanation:
The horizontal line beneath the angle created is always 180 degrees. Because you are given two equations for each angle created, simply write: 180= (3x-3) +(x+19). This gives you 4x+16=180, of which you subtract 16 to 180 which gives you 164. Finally, divide both sides by 4: 4x/4=164/4 and you will get 41. Hopefully I was of aid to you.

[tex]y = -3x + 27[/tex]
Step-by-step explanation:
A parallel line will have the same slope as the given line so we can write the slope-intercept form of the equation as
[tex]y = -3x + b[/tex]
Since the other line goes through the point (9, 0), we can use this to solve for b:
[tex]0 = -3(9) + b \Rightarrow b = 27[/tex]
Therefore, the equation of the parallel line that goes through (9, 0) is
[tex]y = -3x + 27[/tex]

pretty much a rectangle with 800 20 1 at the top

and split the numbers in the box - i tried to recreate it as much as possible
oh then in each little box you have to multiply the numbers so
50 x 800 = 40,000 in the box
50 x 20 = 1,000 in the next box
50 x 1 = 50 in the next box
4 x 800 = 3,200
4 x 20 = 80
4 x 1 = 4
then you add all of them which would be 44,334
