Answer:
y = x + (6+x)
Step-by-step explanation:
Y represents the total number of marbles.
X represents number of blue marbles.
6+X represents number of yellow marbles.
To Solve:
24 = 2x + 6
Subtract 6 from both sides: 18 = 2x
Divide boths sides by 2: 9 = x
Now fill in the values: Blue Marbles = 9, Yellow marbles = 15

True or False: An equation to find Circumference is C = πr2
Answer:
False
Step-by-step explanation:
It's actually C=πd d is diameter or C=πr^2
Answer:
True
Step-by-step explanation: Calculate circumference from area
We are given the area, and by substitution we know that 13π = πr2. We divide out the π and are left with 13 = r2. We take the square root of r to find that r = √13. We find the circumference of the circle with the formula C = 2πr.

Step-by-step explanation:
Parallelogram R S T U is shown. Diagonals are drawn from point R to point T and from point U to point S and intersect at point V. The length of line segment U V is (x + 3) meters and the length of line segment V S is (2 x minus 7) meters. In parallelogram RSTU, what is SU? 10 m 13 m 23 m 26 m
Answer:
26m
Step-by-step explanation:
The diagonals of a parallelogram bisects each other. Hence the length of UV is equal to the length of VS
UV = VS
x+3 = 2x-7
x-2x = -7-3
-x = -10
x = 10
Get SU
SU = UV+VS
SU = x+3+2x-7
SU = 3x-4
Substitute x=10 into the expression
SU = 3(10)-4
SU = 30-4
SU = 26m
Length of SU is 26m

x is a positive integer.
33 = x is a positive integer.
Work out the four possible values of x, writing your values in ascending order.
Answer:
Four possible values of x: 10, 3, 20, 31
Writing it in ascending order : 3, 10, 20, 31, 33
Step-by-step explanation:
Because x is a positive integers it means that x could be any number that goes from zero to infinity.
The possible values of x such that 33/x remains a positive integer in ascending order are 1,3,11 and 33.
What is an integer?An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.
Integer ; ....-2 , -1 , 0 , 1 , 2 , .....
Given the expression, 33/x
Now positive integers are whole numbers ( 1,2,3,...)
To 33/x be the whole number and x is also a positive integer.
33/1 = 33 (1,3 Positive integer)
33/3 = 11 (3,11 Positive integer)
33/11 = 3 (11,3 Positive integer)
33/33 = 1 (33,1 Positive integer)
Hence "The possible values of x such that 33/x remains a positive integer in ascending order are 1,3,11 and 33".

Part A: Select the factors of ?-56
(x-7)
(+7)
(x-4)
(+14)
(X-8)
(x+8)
(x+4)
(x-14)
Answer:
The factors are: (x - 8) and (x + 7)
Step-by-step explanation:
Given
[tex]x^2 - x - 56 = 0[/tex] -- the right equation
Required
Select the factors of the equation
[tex]x^2 - x - 56 = 0[/tex]
Expand the equation
[tex]x^2 + 7x - 8x - 56 = 0[/tex]
Factorize:
[tex]x(x+7)-8(x+7) =0[/tex]
Factor out x + 7
[tex](x-8)(x+7) =0[/tex]
Hence, the factors are: (x - 8) and (x + 7)

Answer:
1204 in²
Step-by-step explanation:
To find the area of a trapezoid, use the following formula: [tex]\frac{b_{1} + b_{2} }{2} h[/tex]. First add the two bases together: 46 + 40 = 86. Now divide that by 2: 86/2 = 43. Now multiply this by the height (28): 43 x 28 = 1204. This is your area: 1204 in².
Hope it helps!
Answer:
1204
Step-by-step explanation:

Answer:
The measure of angle 6 is 72.
The measure of angle 7 is 108.
Step-by-step explanation:
Corresponding angles are equal. So angle 1, 3, 5 and 7 are all equal.
If you look at angle 1 and 2, they are adjacent angles, so together they add up to 180. So if you subtract 108 from 180 you get 72... and we already established that all corresponding angles are equal, so if angle 2 is 72 degrees, we can conclude that angle 6 is as well.
Simplify and write the trigonometric expression in terms of sine and cosine:
tan u + cot u = 1/f(u)
Answer:
we have the expression as;
1/sin u cos u
Step-by-step explanation:
tan u = sin u/cos u
cot u = cos u/sin u
Thus;
sin u/cos u + cos u/sin u
The lcm is sin u cos u
Thus, we have that;
(sin^2 u + cos^2 u)/sin u cos u
But ; sin^2 u + cos^2 u = 1
so we have ;
1/sin u cos u
The requested trigonometric expression in terms of sine and cosine is;
[tex]f(u) = \frac{1}{ \frac{sinu}{cosu} + \frac{cosu}{sinu} } [/tex]
Trigonometric expressions:We must remember,
tan u = sin(u)/cos(u)and cot u = cos(u)/sin(u).Therefore we have;
sin(u)/cos(u) + cos(u)/sin(u) = 1/f(u)
By Cross-product; we have;
[tex]f(u) = \frac{1}{ \frac{sinu}{cosu} + \frac{cosu}{sinu} } [/tex]
Therefore, the required function, f(u) in terms of sin u and cos u is as represented above.

a) Maximum: 10
b) Minimum: - 2
To determine the amplitude we first recognize the midline, so I will answer part d first,
d) We have our maximum as 10, and our minimum as - 2. The midline, by it's name, is a line that divides the graph in half. What we do is determine the average of 10 and - 2 => 10 - 2/2 = 8/2 = 4
Midline: y = 4
Now I will go back to part c,
c) The amplitude would be 6. We take the difference between the maximum and the midline, or the minimum and the midline.
