Answer:
Here we want to solve the equation:
[tex]11^3\sqrt{x-12} = 66[/tex]
First, we can divide both sides by 11^3 to get:
[tex](11^3\sqrt{x-12})/11^3 = 66/11^3[/tex]
[tex]\sqrt{x - 2} = 66/11^3[/tex]
Now remember that:
(√x)^2 = √(x^2) = x
then if we apply this to our equation we get:
[tex](\sqrt{x - 2})^2 = (66/11^3)^2[/tex]
now we need to solve:
[tex]x - 2 = (66/11^3)^2\\x = (66/11^3)^2 + 2 = 2.002[/tex]
Then x = 2.002
Daria bought
a skein of alpaca yarn for $47.50, a skein
of angora yarn for $32.14, a skein of wool
yarn for $16.50, and a pair of knitting
needles for $3.86. How much did she
spend in all? Describe how you calculated
your answer
The total amount Daria spent on all her purchases is $100
In order to determine the total amount Daria spent on all her purchases, the cost of each item has to be added together.
Addition is a mathematical operation that can be used to determine the total sum of two or more values. other basic mathematical operations are subtraction, multiplication and division.
Total amount spent = cost of a skein of alpaca yarn + cost of a skein
of angora yarn + cost of a skein of wool yarn + cost of a pair of knitting
needles
$47.50 + $32.14 + $16.50 + $3.86 = $100

Hello, There! I'll be Glad to help
QuestionAmtrak: 80 miles in 5 hours
Metra: 30 miles in 2 hours
Which train is faster? How do you know?
Answer[tex]\textbf{Amtrak is correct}[/tex]
Step-by-step explanation:
So First we have to figure out Has fast the trains go in 1 hour so we are going to divide...
Metra30 ÷ 2 = 15 Miles (Metra can go 15 Miles in one hour)
Amtrak80 ÷ by 5 = 16 (Amtrak Can go 16 Miles in one hour)
_______________________________________
So If Metra Were to keep going Here are the list of Miles Below
(45 Miles in 3 hours)
(60 Miles in 4 hours)
(75 miles in 5 hours)
________________________________________
Amtrak
(96 Miles in 6 hours)
(112 miles in 7 hours )
(128 miles in 8 hours)
Therefore, Amtrak is the Fastest Train

I need help with factoring trinomals.
Please explain how you got the answer.
9514 1404 393
Answer:
(x +6)(3x +4)
Step-by-step explanation:
The usual approach to this is to look for factors of the product 3·24 that have a sum of 22.
72 = 1·72 = 2·36 = 3·24 = 4·18 = 6·12 = 8·9
Sums of these factor pairs are 73, 38, 27, 22, 18, 17.
Now, you can rewrite the expression splitting the middle term into two parts:
3x² +4x +18x +24
x(3x +4) +6(3x +4) . . . . . . factor by grouping
(x +6)(3x +4) . . . . . . . . . . your factored form
_____
Additional comment
I find this method easiest to explain and to do without error. There are various "X" methods in which you write the product at the top (3·24) and the sum at the bottom (22), then fill in the sides with the factors having that product and sum (4, 18). When the leading coefficient is not 1, there are methods added to this that get you to the correct factors.
One such method is to use the leading coefficient inside parentheses: (3x+4)(3x+18) Then divide that product by the leading coefficient:
(3x +4)(3x +18)/3 = (3x +4)(x +6).
In some cases, each of the binomials needs to be divided by part of the leading coefficient; not the whole thing, as here.

In ΔQRS, q = 9.4 cm, r = 8 cm and ∠S=151°. Find ∠Q, to the nearest 10th of a degree.
9514 1404 393
Answer:
15.7°
Step-by-step explanation:
The law of cosines can be used to find side s:
s² = r² +q² -2rq·cos(S)
s² = 8² +9.4² -2(8)(9.4)·cos(151°) ≈ 283.903
s ≈ 16.849
Then the law of sines can be used to find angle Q.
sin(Q)/q = sin(S)/s
sin(Q) = (q/s)sin(S)
Q = arcsin(q/s·sin(S)) = arcsin(9.4/16.849·sin(151°)) ≈ 15.692°
Angle Q is about 15.7°.

Answer:
I'm pretty sure it's 5
Step-by-step explanation:
It's 5 if: (please confirm before you answer it--the picture is blurry and it's hard to tell).
The line appears to intersect the origin (0,0) and (2.5,12.5).
Slope is rise over run, so if you take the difference in y value and divide it by the difference in x value, you get the slope.
