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]

How many units of a 10% solution are needed to prepare 300 units of a 6% solution?
To prepare 300 units of the 6% solution, the required number of units of 10% solution needed will be 180 units.
Let the number of units of 10% solution = t
We can set up the equation thus :
10% solution × number of units = (300 × 6%)
10% × t = 300 × 6%
0.1t = 0.06 × 300
0.1t = 18
Divide both sides by 0.1 ; to isolate t
0.1t / 0.1 = 18 / 0.1
t = 180
Therefore, 180 units of the 10% solution are required to prepare 300 units of 6% solution.

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.

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

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.

For the function f defined below, what is the value of f(-1)? fx=x+3
-----
2
Answer:
6) C 1
7) A 3 (im not sure for this one because it's blurry)
8) C 1
Step-by-step explanation:
6) Replace the f(x) for -1 since we are told f(x) = -1. We then need to use the inverse operation to get x by itself.
[tex] - 1 = \frac{x - 3}{ 2} [/tex]
Since the opposite of division (which is indicated by the fraction line) is multiplication, we need to multiply the number on the left (-1) times 2.
[tex] - 2 = x - 3[/tex]
For this step, the opposite of subtraction is addition so in this step, we must add 3 to -2.
[tex]1 = x[/tex]
7) Can't explain cause I'm not sure if I'm right
8) To find out the slope of two coordinates we must use the following to determine it.
(IN THE PICTURE ATTACHED)In this case, the y with the little two will be 4 and the y with the little one is 1. 4-1 is 3 and that's the y cooridnate sorted
For the x coordinate, the x with the little two is 1 and the x with the little one is -2. Thus, we must solve 1-(-2) which also equals 3.
Since the final coordinates are 3/3 and it simplifies, the final answer is 1.In the month of February, Doodle Incorporated made 4,000 fidget

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
