Answer:
6 + 1 + 0 7.1= 0 +7 = 1+1=1:1
Step-by-step explanation:
The only true equation is 7 . 1 = 0 + 7.
Define equation? What is Equation Modelling?
Equation is defined as a relation that equates two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given are the following equations -
0 . 3 + 1 = 3.0
6.1.0 = 6 + 1 + 0
7.1 = 0 + 7
1 + 1 = 1 : 1
We have -
0 . 3 + 1 = 3.0
0 x 3 + 1 = 3 x 0
0 + 1 = 3 x 0
1 = 0
false
6 . 1 . 0 = 6 + 1 + 0
6 x 1 x 0 = 7 + 0
0 = 7
false
7 . 1 = 0 + 7
7 x 1 = 7
7 = 7
true
1 + 1 = 1 : 1
2 = 1/1
2 = 1
false
Therefore, the only true equation is 7 . 1 = 0 + 7.

Find the surface area of this cuboid
Answer: 76
Step-by-step explanation:
What time between 6pm and 6:30 pm the hour and minutes hands be exactly 125* degree apart
Answer:
6:10pm
Step-by-step explanation:
At 6:00 the hands are 180° apart.
The hour hand moves 1/12 of circle per hour = 30° per hour = 0.5° per minute.
The minute hand moves 1/60 of the circle per minute = 6° per minute
Angle between the hands decreases by 6-0.5 = 5.5° per minute.
180 - 5.5t = 125
t = 125/5.5 = 10 minutes
The hands are 125° apart at t minutes after 6:00, or 6:10.

What are the solutions to
(m +11)2 = 64?
Answer:
(21 + 11)2 = 64
So, I don't think teachers do this, but this is my way of doing it
Okay, so first, I divided 64 by 2 :
64 ÷ 2 = 32
Then, I subtracted 11 from 32:
21
Now, to check, just do the problem :
(21 + 11)2 = 64
32 * 2 = 64
Answer:
The solutions are:
[tex]m=-3,\:m=-19[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(m\:+11\right)^2=\:64[/tex]
[tex]\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]
solving
[tex]m+11=\sqrt{64}[/tex]
[tex]m+11=\sqrt{8^2}[/tex]
[tex]m+11=8[/tex] ∵ [tex]\sqrt{8^2}=8[/tex]
Subtract 11 from both sides
[tex]m+11-11=8-11[/tex]
Simplify
[tex]m=-3[/tex]
now solving
[tex]m+11=-\sqrt{64}[/tex]
[tex]m+11=-\sqrt{8^2}[/tex]
[tex]m+11=-8[/tex] ∵ [tex]\sqrt{8^2}=8[/tex]
Subtract 11 from both sides
[tex]m+11-11=-8-11[/tex]
Simplify
[tex]m=-19[/tex]
Thus, the solutions are:
[tex]m=-3,\:m=-19[/tex]

Answer:
4
Step-by-step explanation:
4 is attached to y (a variable)
Please help if you can. Thank you
Answer:
Step-by-step explanation:
x-4 = log (base3) of 6; add 4 to both sides
x= [log (base3) of (2*3) ] +4; split 6 to 2*3
x= [log (base 3) of 3 + log ( base 3) of 2] + 4; use rule log(ab) = log a+log b
x= log (base 3) of 2 + 1+ 4; use rule log (base a) of a = 1
x= log (base 3) of 2 + 5; put in the calculator
x≈5.63

In the month of February, Doodle Incorporated made 4,000 fidget
spinners. Sales were so good that the owner set a goal to increase
production of the spinners by 13% each month until the production
reached 40,000. About how many months would that take? Round to
the nearest month.
Answer:
19 months
Step-by-step explanation:
As an equation, this can be represented as: x=4000(1.13ᵃ), where x is the amount being produced now and a is the time in months. To find our answer, let x equal 40,000.
40000=4000(1.13ᵃ)
10=1.13ᵃ
log(1.13)(10)=a
a≈18.84, or 19 months
the expression 3(-2m + 5)-6(-4m-2) can be written in the form am + b what is the value of a + b in number form
Answer:
45
Step-by-step explanation:
The required simplified value of the given expression a + b is given as 45.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
According to the question,
3(-2m + 5)-6(-4m-2) = am + b
-6m + 15 +24m + 12 = am + b
18m + 27 = am + b
From the comparison,
a = 18 and b = 27
Now,
a + b = 18 + 27
= 45
Thus, the required simplified value of the given expression a + b is given as 45.
