Answer:
A dot is a physical object, not a mathematical object. A dot has a size and is roughly circular, but the size is not defined. It’s a fuzzy concept; how big does it have to be before it’s no longer a dot but a blot? An how irregular can a dot be?
A point is a mathematical object in geometry. It has a position but no size. It has no definition because none of the basic objects of mathematics has a definition. The axioms of geometry give relationships between and properties of undefined terms such as point, line and plane.

Brian has 8 feet of canvas. He needs 1/4 foot to make a painting.
How many paintings can Brian make?
Answer:
32 paintings
Step-by-step explanation:
You have to divide 8 by [tex]\frac{1}{4}[/tex]
turn 8 into a fraction by putting a 1 under it, [tex]\frac{8}{1}[/tex], and flip the other fraction, [tex]\frac{4}{1}[/tex]
now, you multiply the fractions
[tex]\frac{8}{1}[/tex] ×[tex]\frac{4}{1}[/tex]= [tex]\frac{32}{1}[/tex], so you get 32 over one, which you can just simplify into 32
Brian can make 32 paintings.
The solution is, Brian can make 32 paintings
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
You have to divide 8 by
turn 8 into a fraction by putting a 1 under it, 8/1 , 4/1 and flip the other fraction,
now, you multiply the fractions
8/1×4/1=32 ,
so you get 32 over one, which you can just simplify into 32
Brian can make 32 paintings.

What is y when x =17
Answer:
The answer is 30
Answer:
y = 30
Step-by-step explanation:
There are 2 ways to find the answer to this.
#1
The relationship between x and y is y = x+13.
x is 17 so 17+13 would equal y.
17+13 = 30
y = 30
#2
rule for y: y increases by 4
26+4 = ?
26+4 = 30
y = 30

Solve y = x + 6 for X.
x= y + 6
x= -y + 6
x = y - 6
x= -y - 6
Answer:
x=y-6
Step-by-step explanation:
First, flip the equation.
x+6=y
Finally, add -6 to both sides.
x+6+−6=y+−6
x=y−6
Find the value of. X in the proportion 5/9=x/36
Answer:
x=20 hope this helps :)
The value of X is 20.
To find this answer, you must first find the least common denominator of both fractions. In this case, the LCD is 36.
Next, you multiply the left side by 4/4. The fraction 4/4 is simply found by dividing the right side denominator (36) by the left side denominator (9). 9 goes into 36 4 times.
5/9 * 4/4 = 20/36.
Thus meaning X = 20. I hope this helps!

Elsa, Chang, and Bob have a total of 104 in their wallets. Chang has 3 times what Bob has. Elsa has 6 more than Bob. How much does each have?
Answer:
Bob=19.60
Elsa=25.60
Chang=58.80
Step-by-step explanation:
(E)lsa + (C)hang + (B)ob=104
C=3B
E=B+6
substitute
(B+6)+3B+B=104
5B+6=104
5B=98
5B/5=98/5
B=19.60
E=19.60+6=25.60
C=3(19.60)=58.80

6. Write an equation for a line that passes through (6, 12) and (10, 20).
Answer:
Step-by-step explanation:
Y = mx +b / Slope intercept form
mx - y = -b / Standard form
6m -2 = -b / Plug in ( 6,2)
-9m -10 = -b / Plug in ( -9, 10)
Solve the system of equation for m and b.
6m -2 = -9m -10 , then 15m = -8 m = -8/15
b = -6m +2 ,then b= -6 ( -8/ 15) +2 = 78/15
-8/15 X - y = - 78/15
8X +15y = 78 / Equation of in standard form
Note: This is a different methods of solving this problem. All methods find their roots coming from the basic premises.
Equation of a line in the slope intersect form is
Y = mx +b
To convert to standard form of ax + by =c
Simply move over the parameters
mx - y = -b where a = m , and c = -b
Then we feed coordinates of 2 points in there
make a 2 equation with 2 unknown( m,b) to
solve.

Bradley's Copiers sells and repairs photocopy machines. The manager needs weekly forecasts of service calls so that he can schedule service personnel. Use the actual demand in the first period for the forecast for the first week so error measurement begins in the second week. The manager uses exponential smoothing with a = 0.1. Forecast the number of calls for week 6, which is next week.
Week Actual Service Calls 2

The forecast for week 6 is ________ service calls.
Answer:
28.86
Step-by-step explanation:
According to the scenario, computation of given data are as follows,
Exponential smoothing a = 0.1
we can calculate forecast for each week by using following formula,
Forecast for week = Forecast of last week + a × ( actual calls of last week - forecast of last week)
By using this method, forecast for all week are as follows

the length of the rectangle is 7 cm less than 4 times its width the area is 15 square cm
Answer:
I guess the answer is 4.4 cm or 22/5 cm
Step-by-step explanation:
AREA= 15cm^2
Let the Breadth be x
Length= 4x-7
Area = l×b
15 = 4x-7×x
15+7=4x+x
22=5x
22÷5=x
4.4=x
Therefore, Breadth= 4.4cm Length= 10.6cm

-8x is less than or equal to 32
What is the inequalities that are possible.
Answer:
We conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
The solution graph on the number line is also attached.
Step-by-step explanation:
Given the inequality
[tex]-8x\:\le 32[/tex]
Solving the inequality
[tex]-8x\:\le 32[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\left(-8x\right)\left(-1\right)\ge \:32\left(-1\right)[/tex]
Simplify
[tex]8x\ge \:-32[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}\ge \frac{-32}{8}[/tex]
Simplify
[tex]x\ge \:-4[/tex]
Therefore, we conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]

In ΔIJK, k = 7.2 cm, ∠J=55° and ∠K=67°. Find the length of i, to the nearest 10th of a centimeter.
Answer:
6.6
Step-by-step explanation:
The length of i is 6.6 units(after the nearest 10th of a centimeter) if in ΔIJK, k = 7.2 cm, ∠J=55°, and ∠K=67°.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle:
As we know the sum of the triangle is 180°
So I = 180 - 55 - 67 = 58°
Applying sin law to calculate the value of i:
[tex]\rm \frac{i}{sin58} = \frac{k}{sin67}[/tex]
[tex]\rm i = \frac{7.3\times sin 58}{sin67}[/tex]
i = 6.633 units ≈ 6.6 units (sin58 = 0.848, and sin67 = 0.920)
Thus, the length of i is 6.6 units(after the nearest 10th of a centimeter) if in ΔIJK, k = 7.2 cm, ∠J=55°, and ∠K=67°.
