Vertical angles
Answer:
a) 90°
b) 90° - 35° = 55°
c) 65° - 40° = 25°
d) 90° - 65° = 25°
e) 180° - 65° = 115°
f) 180° - 35° = 145°
g) 180° - 40° = 140°
h) 65° + 35° = 100°
180° - 100° = 80°
i) 90° - 40° = 50°
j) 35° + 40° = 75°
180° - 75° = 105°

7. CHALLENGE: Use the digits 0 to 9 to make the equation true. You don't need to use all thedigits you can only use each digit once.
20 = ___+(___-___)×___
9514 1404 393
Answer:
20 = 2 + (7 -4) × 6
Step-by-step explanation:
The Order of Operations requires the parentheses be evaluated first, then the multiplication performed. Finally, the addition is performed.
If each of the blanks is filled with a single digit, the result of the multiplication must be a composite number greater than 10. Those are 12, 14, 15, 16, 18, 20. For the expression shown above, we have chosen to make the product be 18. That means the first blank is filled with 2 and the remaining blanks must evaluate to one of the products 2×9 or 3×6.
We have chosen 6 for the last blank, so the two blanks in parentheses must have a difference of 3. The digits 2 and 6 cannot be used, leaving possible choices as (3-0), (4-1), (7-4), (8-5).
Our final expression is chosen to be ...
20 = 2 +(7 -4)×6

Evaluate the following integral over the ellipse
The underlying vector field,
F(x, y) = -y/(4x ² + 9y ²) i + x/(4x ² + 9y ²) j,
is conservative, so any integral of F over a closed path is 0.
To establish that F is conservative, we want to find a scalar function f(x, y) whose gradient is equal to F(x, y), which entails solving
[tex]\dfrac{\partial f}{\partial x}=-\dfrac y{4x^2+9y^2}[/tex]
[tex]\dfrac{\partial f}{\partial y}=\dfrac x{4x^2+9y^2}[/tex]
Integrating the first equation with respect to x yields
[tex]f(x,y)=-\dfrac16\arctan\left(\dfrac{2x}{3y}\right)+g(y)[/tex]
and differentiating with respect to y gives
[tex]\dfrac x{4x^2+9y^2}=\dfrac x{4x^2+9y^2}+\dfrac{\mathrm dg}{\mathrm dy} \implies \dfrac{\mathrm dg}{\mathrm dy}=0 \implies g(y)=C[/tex]
Work out the size of angle x
Answer:
[tex]x=47^{\circ}[/tex]
Step-by-step explanation:
By definition, parallelograms have two pairs of parallel sides. Therefore, AD and BC are parallel, and the angles marked with [tex]x[/tex] and [tex]47^{\circ}[/tex] are alternate interior angles. Since alternate interior angles are equal, we have [tex]x=\boxed{47^{\circ}}[/tex]
I need help answering h to is question
Answer:
[tex] y = \frac {4}{3}x - 2[/tex]
Step-by-step explanation:
Given the following data;
Points on the line (x1, y1) = (3, 2)
Slope, m = 4/3
To write the equation in slope intercept form;
First of all, we would determine the intercept of the line.
Equation of straight line is y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Substituting the values in order to find the intercept, we have;
2 = 4/3(3) + c
2 = 4 + c
c = 2 - 4
c = -2
Therefore, the equation of line is y = 4/3x - 2
[tex] y = \frac {4}{3}x - 2[/tex]
What set or sets does negative squareroot of 20 belong to? is it a real number, rational, integer, whole number, irrational, or natural?
Answer:
Real number and Irrational number
Step-by-step explanation:
Given
[tex]-\sqrt{ 20[/tex]
Required
The set it belongs to
First, solve the expression
[tex]-\sqrt{ 20} = -4.472136[/tex]
The above number is not an integer and it is not whole or natural because it has decimal points
It is not a rational number because it cannot be expressed as a simple fraction
However, the number can be categorized as either irrational or real because of the level of the decimal point in the result

Which equation represents the graphed function?
O y=-3x + 3
O y = 3x - 3
O y = 3x - 1
O y=-x+3
Answer:
y = -⅓x + 3
Step-by-step explanation:
To find the equation of the graph in the form of y = mx + b (slope-intercept form), we have to find the slope (m) and the y-intercept (b) of the graph:
Slope (m) = change in y/change in x
Slope (m) using the two points on the line, (0, 3) and (3, 2):
m = (2 - 3)/(3 - 0) = -1/3
m = -⅓
y-intercept (b) = 3 (the y-axis is intercepted at this point)
✔️To write the equation, substitute m = -⅓ and b = 3 into y = mx + b:
Thus,
y = -⅓x + 3
Find the volume of the rectangular pyramid below.
Answer:
315 yd cubed
Step-by-step explanation:
To find the volume of the pyramid, we first need to consult the equation below. Thebase is for the rectangular portion, then after multiplied by the height it is divided by 3 to get the pyramid.
[tex]\frac{1}{3} (B * H )[/tex]
To get the base, we multiply the length by the width.
21 * 9 = 189
189 * 5 = 945
945 divided by 3 = 315
Answer:
Let's find the base area:
21 x 9 = 189
Now let's multiply the base area by the height:
189 x 5 = 945
Now let's divide by 3( x 1/3 ):
945 divided by 3(x 1/3) = 315 yd^3 is your answer
Step-by-step explanation:
Formula area of a rectangular Pyramid(just like any other pyramid):
BH x 1/3
To find base we multiply length by width just using the basic formula of finding area of a rectangle.
Then we multiply our base area by our height.
One we've done that we now divide by 3(multiplying by 1/3)
Given the Cos(x) = -2/3, then the Sec(x) = ?
What is the answer
Answer:
[tex]sec x = - \frac{3}{2}[/tex]

Answer:
sec x = -3/2
Step-by-step explanation:
sec = 1/cos
sec x = 1 / (-2/3)

The circumference of a circle is 36 cm.
What is the radius of the circle?
Answer:
The radius is 6 cm rounded
Step-by-step explanation:
[tex]C[/tex] stands for circumference
[tex]r[/tex] stands for radius
here's the formula to find the radius: [tex]r=\frac{C}{2\pi }[/tex]
[tex]r=\frac{36}{6.283}[/tex]
[tex]r=5.729[/tex]
Hope this helps
Answer:
r = 18/pi or approximately 5.732484076 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
36 = 2*pi*r
Divide each side by 2 pi
36 / (2pi) = 2pi r/ (2pi)
18/ pi = r
Using 3.14 for pi
18/ 3.14 = r
5.732484076 = r

I'm kinda lost here, what do I do when the quadrant is given? CanI have some of these solved at least with steps?
Answer:
See Explaination
Step-by-step explanation:
According To Question
In Quadrant-1 (0* to 90*) ( All the Trignometry Functions are Positive )In Quadrant-2 (90* to 180*) (Only Sine & Cosecant are Positive)In Quadrant-3 (180* to 270*) (Only Tangent & Cotangent Are Positive)In Quadrant-4 (270* to 360*) ( Only Cosine & Secant Are Positive)(Diagram, Please Find In Attachment)
Question 38 . Cos ∅ = 12/13 ∅ in Quadrant-4(Where only Cos & Sec are Positive all other Functions Are Negative in this Quadrant)
Now ∅ Represent a Right Angle Triangle with Base=12 Perpendicular=5 & Hypothenese=13
other Five Trignometry Functions Are as FollowSin∅ = -5/13 , Cosec∅=-13/5 , Tan∅=-5/12 , Cot∅=-12/5 & Sec∅=13/12
Question 39 . SinX=-3/4 X Lies in Quadrant-3(Where only Tan & Cot are Positive all other Functions Are Negative in this Quadrant)
Now For Other Trignometry FunctionsFind By Using Basic Formulas
[tex]SinX^{2}+CosX^{2}=1[/tex] ↔ Put Value of Sin∅=-3/4
We get CosX= ±[tex]\frac{\sqrt{5} }{4}[/tex] (but X Lies in Quadrant-3 Where Cosine Is Negative , So Neglect CosX= +[tex]\frac{\sqrt{5} }{4}[/tex])
So CosX= -[tex]\frac{\sqrt{5} }{4}[/tex] ...... now you get the point . All Questions Will Solve like This .

Trina: 5 + 3.25h = 21.25
Now, subtract 5 from both sides.
3.25h = 16.25
Now, divide both sides by 3.25.
h = 5
Trina spent 5 hours at the facility.
Ralph: 21.25 - 5/ 3.25 = h
Subtract 5 from 21.25
16.25/ 3.25 = h
Now divide
5 = h
Ralph will spend 5 hours at the facility to spend the same amount as Trina.

Perimeter of a rectangle is 11 inches. The length of the rectangle is 1/2 inches what is the width of the rectangle?
Answer:
=5
Step-by-step explanation:
perimeter= 2(L)+2(W)
11 =2(1/2)+2W
11=1+2W
11-1=2W
10=2W
Both sides divided by 2
therefore The width is 5
