Answer:
43%
Step-by-step explanation:
If there are 43 yellow marbles out of 100 total, the fraction that will be used is 43/100. The percentage is found by dividing the numerator (top) by the denominator (bottom). The percentage is the first two numbers in the decimal. For future reference, if a decimal were to have more than 2 or 3 digits, the number would be rounded to the 4th and the decimal point would be placed between the 2nd and 3rd digits.
Solve the system of equations -x + 4y = 6 and 4x – 8y = 0 by combining the equations.
(- x +4y =6)
(4x -8y =0)
-x + 4y = 6
4x - 8y = 0
Answer:
x=6 y=3
Step-by-step explanation:
Isolate x for -x+ 4y = 6: x= -6+ 4y
Substitute x = -6 + 4y
4(-6+ 4y) - 8y = 0
Simplify
-24+ 8y =0
Isolate y for -24 + 8y = 0: y =3
For x = -6+ 4y
Substitute y =3
X= -6+ 4 × 3
Simplify
X=6
The solutions to the system of equations are:
x=6 y=3

Step-by-step explanation:
A polygon has 5 sides. The interior angle measures are 117°, 104°, 113°, 106°, and x°. Find the value of x.
The measure of the angle x is 100 degree if the polygon has 5 sides. The interior angle measures are 117°, 104°, 113°, 106°,
What is a regular polygon?A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
We know the sum of the interior angles in a polygon is given by:
= 180(n - 2)
= 180(5-2) (n = 5)
= 540 degree
117°+104°+113°+106°+x = 540
440 + x = 540
x = 100 degree
Thus, the measure of the angle x is 100 degree if the polygon has 5 sides. The interior angle measures are 117°, 104°, 113°, 106°,

100 points to who is correct
Answer:
The correct answer is 26.9
Step-by-step explanation:
You know that the total angle measurement of angle u and 63.1 is 90 degrees. If you subtract 63.1 from 90, you get 26.9, which is the measurement to angle u.
Answer:
26.9
Step-by-step explanation:
angle u is equal to the space next to 63.1, because of Opposite Angle Theory. We'll call this x
63.1 + x = 90
x = 90 - 63.1
x = 26.9
Therefore, x = u = 26.9
How do I solve this problem
Answer:
#9 24 T-Shirts for $168
#10 the diffirence between 30 T-Shirts and 9 T-Shirts is 147
Step-by-step explanation:
so to get the cost (c) for 1 T-Shirt you need to divide 147 by 21
147 ÷ 21 = 7
so c=7
10x7=70
70x3=210
30x7=210
so 30 shirts cost $210
and 9x7=63
so now it is time to do the rest of the math.
210

x^2+ (y + 3)^2 = 81
Center:
Area:
Answer:
Center: 254.5
Area: 254.5
Explanation:
Equation: x² + (y + 3)² = 81Circle formula:
(x - h)² + (y - k)² = r²where (h, k) is the center points, r is radius
Rewriting the equation:
(x -0) ² + (y - (-3))² = 9²Identify the following:
(h, k) = (0, -3), radius: 9Area of Circle:
π(radius)² = π(9)² = 81π = 254.46 = 254.5General equation
(x-h)²+(y-k)²=r²So
(x-0)²+(y+3)²=81(x-0)²+(y+3)=9²Radius=9

Stephanie works in retail sales. Her salary is $500 plus 15% commission on
weekly sales.
Write a function expressing the relationship between Stephanie's wages and
her monthly sales.
The function w(x) = 0.15x + 500 represents the relationship between Stephanie's wages and her monthly sales.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
Let's suppose the Stephanie's wages is w and weekly sale is x
So we can model a function:
[tex]\rm w(x) = \dfrac{15}{100}x+500[/tex] or
w(x) = 0.15x + 500
Thus, the function w(x) = 0.15x + 500 represents the relationship between Stephanie's wages and her monthly sales.

Does anyone know the answer? Please and Thank you! Algebra
Answer:
Step-by-step explanation:
y = mx + b
we can see the slope is down hill, so it's negative
when the X is zero then it's 2
b = 2
slope is rise over run 2/3
y = -2/3x + 2
the slope is -2/3 (note the negative)
the y intercept is 2

What are the intercepts of 7x+2y-14z=56
Hey there!
I believe your answer should be: OPTION B. because
7x + 2y - 14z = 56
7(8) + 2(28) - 14(4) = 56
56 + 56 - 56 = 56
112 - 56 = 56
56 = 56
So, that’s why possibly Option B. could be your result

Which of the following is not
necessarily true for all rectangles.
For f(x) = 3x - 5 and g(x) = x² + 2, find (f+ g)(x).
Answer:
(f+ g)(x) = x^2 + 3x -3
Step-by-step explanation:
f(x) = 3x - 5 and g(x) = x² + 2,
(f+ g)(x) = 3x-5 + x^2 +2
Combine like terms
(f+ g)(x) = x^2 + 3x -3

Two angles are complementary. One angle is 30 more than the other angle. Find the value
of both angles.
Answer:
α=30, β=60
Step-by-step explanation:
we have angles α and β where α + β =90 & β=α+30
this gives us a system of equations that can be solved through substitution
[tex]\alpha +\beta =90\\\beta =\alpha +30[/tex]
substitute to solve for α: α+(α+30)=90
2α+30=90
2α=60
α=30
substitute α to find β:
β=α+30
β=(30)+30 = 60

Answer:
∠x=41°
Step-by-step explanation:
Supplementary Angles are angles that equal 180°
1. Use the equation
∠x+∠y=180°
2. Fill in the given values
∠x+139°=180°
3. Solve
Subtract 139 from both sides
∠x+139°=180°
-139° -139°
4. Answer
∠x=41°
