185 is to 14.8 as x is to 18.5
185/14.8 = x/18.5
x = 185(18.5)/14.8
x = $231.25

If a²+b²=8ab, determine (a+b) in terms of a and b
[The question's not wholly right! Since, (a+b) has a and b in it, it already is in terms of a and b. Here, we'll be representing (a+b) in terms of ab]
Answer:
[tex]\mathsf{\sqrt{10ab} }[/tex]
Step-by-step explanation:
We have the rules of indices, one of which is:
[tex]\boxed{\large{\mathfrak{(a+b)^2=a^2+b^2+2ab}}}[/tex]
Indices are the powers, the numbers written as superscript in front of a variable or the numbers that come along with "^". It shows how many times a number is to be multiplied by itself.
In the question, we're provided with one equation, i. e.,
a² + b² = 8ab . . . . . . . . (¡)And, were asked to find out the value of (a+b) in terms of ab.
The above rule has variables that fit in the question efficiently!
So, instead of solving for (a+b), we'll be solving for (a+b)², then go for (a + b):
=> (a + b)² = (a² + b²) + 2ab
from eqn. (¡):
=> (a + b)² = 8ab + 2ab
=> (a + b)² = 10ab
taking under root on both the sides:
=> (a + b) = [tex]\mathsf{\sqrt{10ab} }[/tex]
That's the answer, [tex]\mathsf{\sqrt{10ab} }[/tex]!

Find the direct variation.
if y=28 when x= 168, find y when x =108.
Answer:
18
Step-by-step explanation:
168 : 28 : : 108 : y
168 / 28 = 108 / y
6 = 108 / y
6 * y = 108
y = 108 / 6
y = 18
Answer:
y = 18
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 28 when x = 168
28 = 168k ( divide both sides by 168 )
[tex]\frac{28}{168}[/tex] = k , that is
k = [tex]\frac{1}{6}[/tex]
y = [tex]\frac{1}{6}[/tex] x ← equation of variation
When x = 108 , then
y = [tex]\frac{1}{6}[/tex] × 108 = 18

Use the Pythagorean theorem to find x, in simplest radical form
Answer:
[tex]4\sqrt{21}[/tex]
Step-by-step explanation:
Pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex].
Which in this case:
'c' is hypotenuse. (hypotenuse = 20)
'a' and 'b' are the other sides. (a = x, b = 8)
[tex]a^{2} +b^{2}= c^{2}[/tex] [tex]x^{2} +8^{2} =20^{2}[/tex] [tex]x^{2} + 64 = 400[/tex] [tex]x^{2} = 336[/tex]Now we should just take square root from the both sides.
and the answer will be [tex]\sqrt{336}[/tex] or [tex]-\sqrt{336}[/tex], but a side of a triangle can not be a negative number! so the answer will be [tex]\sqrt{336}[/tex].
As you see [tex]\sqrt{336}[/tex] is not the simplest radical.
We can write [tex]\sqrt{336}[/tex] as [tex]\sqrt{16 * 21}[/tex].
And from the laws of radical we can write [tex]\sqrt{16*21}[/tex] as [tex]\sqrt{16} * \sqrt{21}[/tex].
[tex]\sqrt{16} * \sqrt{21} = \sqrt{16}\sqrt{21} = 4\sqrt{21}[/tex]

The revenue from selling x shirts is f(x) = 11x. The cost of buying x shirts is cx) = 6 x + 20. The profit from selling x shirts is p(x) = HX) - cx). What is p(x)?
Answer:
P(x) = 5(x) - 4(x) as 20(x) = 4(5) is added to 5(x) = 25 -20 = 5 so profit fro one shirt is set = 1 as 5 * 1 = 5 and (x) = 5
Step-by-step explanation:
11x - 6( ?)+20 = p(?) -H(?) - c (?) = 11x - p(x) = HX) - cx) = 6(x )+20 = 11x-6x -20 = 5x -20 = P(x) = 5(x) - 4(x)

1.Azad has $500 and wants to go on a holiday, but does not have sufficient money. He decides to save $40 per week for a number of weeks to make up the deficit.
How much will he have saved at the end of the 5th week? Explain your answer.
2.A baker has 400kg of flour on the first day of the month and uses no flour that day. How much will he have at closing time on the 17th day of the month, if he uses 24 kg each day after that?
1. At the end of the 5th week he would have saved a total of $700
2. The amount of flour he would have at the closing time on 17th of the month will be 16kg
1.
Azad amount = $500
He wants to go on a holiday but he lacks sufficient money. This means the $500 in his possession is not enough.
He decided to save $40 dollars per week for a number of weeks to make up the deposits.
let
w = number of weeks
Therefore, his saving for any number of weeks will be
40wThe amount he would have saved for 5 weeks will be
40×5=$200
The total amount in his possession at the end of the fifth week will be 200 + 500 = $700
2.
The baker has 400 kg of flour. The first day of the month he didn't use any flour. This means on the first day of that month the flour was still 400 kg. The amount he has on the 17th day of the month can be calculated below.
The 17th day simply implies he used the flour for 16 days, the first day of the month he didn't use anything. He uses 24 kg for each day. Therefore the amount he uses for 16 days will be
16×24=384 kgThe amount he has at the closing time of 17 days of the month will be
400kg - 384kg = 16kgCheck here for similar algebra problems: https://brainly.com/question/22779754?referrer=searchResults
Line a passes through points (3, 6) and (1, 15). Line b is parallel to line a. What is the slope of line b?
Answer:
9/-2
Step-by-step explanation:
First, find the slope
(15-6)/(1-3)
9/-2
Answer:
[tex]slope\ of \ line\ b = - \frac{9}{2}[/tex]
Step-by-step explanation:
Since line a and b are parallel, the slope of a = slope of b.
therefore,
[tex]slope\ of \ line\ a = \frac{y_2 - y_1}{x_2-x_1} \ \ \ \ \ x_ 1 = 3 , \ y_ 1 = 6 \ , \ x_2 = 1 , \ y_2 = 15[/tex]

What’s the rise over run pleas???
9514 1404 393
Answer:
-1/5
Step-by-step explanation:
To find the ratio of rise to run on a graph, it is convenient to start by looking for points where the graph crosses the intersection of grid lines. This lets you read the exact coordinates of the points, without any guessing.
In the attachment, the grid crossings we chose are circled.
The "rise" is the vertical distance between the points. If the right point is lower, the "rise" is negative.
The "run" is the horizontal distance between the points.
The reason for choosing grid crossings is that it then becomes fairly easy to count the grid lines between the points, vertically and horizontally.
On this graph, the "rise" is -1 for a "run" of 5. Then the slope, or ratio of rise to run, is ...
m = rise/run = -1/5 . . . . . . slope of the line
On a coordinate plane, 2 straight lines are shown. The first solid line has a positive slope and goes through (0, negative 2) and (2, 0). Everything to the left of the line is shaded.

i-that doesn't help
Step-by-step explanation:
solve for x
2x-y=r
(Show solving steps please)
Answer:
x=r/2+y/2
Step-by-step explanation:
2x-y=r
you want x all by itself, move y first by adding y
2x = r + y
divide both r and y by 2 to leave x all by itself.
2x/2 = r/2 + y/2
2/2 = 1 so it's really 1x
x= r/2 + y/2

Answer: 18 dozen cookies.
Step-by-step explanation: If 2 eggs make 3 dozen cookies and you have a dozen eggs divide 12/2 = 6. Then multiply 6*3 = 18.
Answer:
18 dozen cookies
Step-by-step explanation:
2 eggs makes 36 cookies
That means 2x=36
x=18
Now plug that into the equation.
12(18)=216
216 is how many cookies
