The equation that represents the number of weeks that is needed to baby sit to buy gaming chair is 35.5w + 136.45 = 455.95; w = 9 , the correct option is (b) .
In the question ,
it is given that
the cost of the gaming chair = $455.95
amount of money already saved for the gaming chair = $136.45
amount of money earned by baby sitting each week = $35.50 .
let the number of weeks required to baby sit is " w " .
the equation can be represented by
cost of chair = money saved + money earned in w weeks
Substituting the values from above ,
we get
455.95 = 136.45 + 35.5w
On solving further ,
136.45 + 35.5w = 455.95
35.52w = 455.95 - 136.45
35.52w = 319.5
w = 319.5 / 35.52
w = 8.99
w ≈ 9
the number of weeks = 9
Therefore , The equation that represents the number of weeks that is needed to baby sit to buy gaming chair is 35.5w + 136.45 = 455.95; w = 9 .

Hi! I solved this using the FOIL, or firsts, outsides, insides, and lasts, to simplify:
The firsts, or F, would be: x*x which equals x squared (x^2)
The outsides, or O, would be: x*5 which equals 5x
The insides, or I, would be 7*x which equals 7x
The lasts, or L, would be 7*5 which equals 35
Then, the FOIL method says to add up all the answers you got together:
x^2+5x+7x+35
and then you simplify and get:

Two angles are said to be complementary if their sum is 90°.
Given, m∠A = (2x − 27)° and m∠B = (3x + 27)° are supplimentary to each other.

The completion of the ratios, resulting from the square feet occupied by Departments A and B, and the amounts of allocated overhead costs to the two departments are as follows:
Ratio Amount
Department A 0.25 $15,000
Department B 0.75 $45,000
What is the ratio?The ratio is the proportion of the whole shared by two or more numbers.
Ratios are fractional values like proportions.
Ratios, depicted in fractions, decimals, and percentages, show how much a value or variable is contained in another.
Total distributable overhead = $60,000
Ratios = 10,000:30,000
= 1:3
Sum of Ratios = 4
OR
= 0.25:0.75
Sum of Ratios = 1
Overhead Allocation:Department Square Feet Ratio Amount of Overhead Allocated
Dept. A 10,000 A = 1 B = $15,000 ($60,000 x 0.25)
Dept. B 30,000 C = 3 D = $45,000 ($60,000 x 0.75)
Thus, based on the cost driver ratios, Department A bears $15,000, while Department B will be allocated $45,000 of the distributable overheads.

The values of the composite functions f(g(x)) and g(f(x)) are (x/4) and (4x - 9),respectively.
We are given two functions, f(x) and g(x). The function f(x) is defined as 1/(x - 3). The function g(x) is defined as (4/x) + 3. A function connects an input to an output. It is analogous to a machine with an input and an output. And the outcome is somehow connected to the input. We need to find the composition of the functions.
The first composition is f(g(x)). The composite function is solved below.
f(g(x)) = f((4/x) + 3)
f(g(x)) = 1/([(4/x) + 3] - 3)
f(g(x)) = 1/(4/x)
f(g(x)) = x/4
The second composition is g(f(x)). The composite function is solved below.
g(f(x)) = g(1/(x - 3))
g(f(x)) = (4/[1/(x - 3)]) + 3
g(f(x)) = 4(x - 3) + 3
g(f(x)) = 4x - 12 + 3
g(f(x)) = 4x - 9

If g(x) is the image of y=−2x^2−20x+2 after a translation right 4 units and up 2 units, write the equation of g(x) in the standard form of a quadratic function and describe its graph.
Enter the quadratic expression in standard form, a(x−h)2+k .
The standard form equation is g(x)=
The image of y = −2x^2 − 20x + 2 after a translation right 4 units and up 2 units is written in:
the form a(x−h)^2 + k is -2(x + 1)^2 - 107standard form of the equation is g(x) = -2x^2 - 4x - 108The graph will be a vertical parabola opening downwards
How to get the transformation imagewhen the function y = −2x^2 − 20x + 2 translates right 4 units it gives
y = -2(x - 4)^2 − 20(x - 4) + 2
going up two units
y = -2(x - 4)^2 − 20(x - 4) + 2 + 2
simplifying the equation further gives
y = -2(x - 4)(x - 4) − 20(x - 4) + 4
y = -2(x^2 - 8x + 16) - 20x - 80 + 4
y = -2x^2 + 16x - 20x - 32 - 80 + 4
y = -2x^2 - 4x - 108
completing the square
-2x^2 - 4x - 108 = 0
-2x^2 - 4x = 108
-2x^2 - 4x + (4/4)^2 = 108 -(4/4)^2

How to find the value of cos x°?
We will use trigonometrical ratios to solve this problem. Below are the definitions of the trigonometrical ratios:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent or tan = sin/cos
The opposite is the side the angle of consideration is facing
The hypotenuse is the side the right angle is facing
The adjacent is the side left after determining the opposite and hypotenuse
Given: tan x° = e/8 and sin x° = e/f
Since tan = opposite/adjacent, that means in tan x° = e/8, opposite = e and adjacent = 8. Also, sin = opposite/hypotenuse, so in sin x°= e/f, hypotenuse = f
And cos = adjacent/hypotenuse. Thus, cos x° = 8/f.
Therefore, the value is cos x° = 8 divided by f is the answer. Pick the first option
