use angle addition postulate:
---
1) angle (2x+10) and (x+5) are supplementary, meaning they add up to 180 degrees so
(2x+10)+(x+5)=180
3x+15=180
x=55
---
2) angle (x-30) and x are complementary, meaning they add up to 90 degrees
(x-30)+x=90
2x-30=90
x=60

Answer:
CBD = 63 degrees
Step-by-step explanation:
To find CBD, we must first find the value of x. To do so, we use this equation since CBD and ABC equal 96 degrees:
(6x+27) + (7x-9) = 96
13x+18 = 96
13x+18-18 = 96-18
13x = 78
13x/13 = 78/13
x = 6
Now that we know the value of x, we factor it in to CBD to find its true value:
6x+27
6(6)+27
36+27
= 63 degrees
To check if this answer is correct, we can also find the value of ABC and see if the two values equal 96:
7x-9
7(6)-9
42-9
= 33 degrees
63 + 33 = 96
The answer is correct. CBD = 63 degrees and ABC = 33 degrees.

A gallon of gas costs $3. 05 per gallon. Joey's car gets 35 miles per gallon on the highway and 27 miles per gallon in the city. Using the
highway, Joey drives at an average speed of 54 miles per hour, and it takes him 0. 5 hours to get to work. The highway has one $1. 25 toll.
Using a city street route, Joey drives at an average speed of 36 miles per hour, and it takes him 1 hour to get to work.
Which quantities would be used to determine the total cost for Joey to drive to work using the highway? Choose all that apply. A. 0. 5 hours B. 1 hour C. $1. 25 per car D. $3. 05 per gallon E. 27 miles per gallon F. 35 miles per gallon G. 36 miles per hour H. 54 miles per hour
Answer: using the street route, he drove for half hour/0.50hr or 30minutes. Hence he covered 27miles on that trip, deducted from 54miles per hour for 0.5hr.Paid a toll fee of $1.25 which is the cost per car at the toll.

Find the volume of the cylinder.
Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi.
Volume is the measure of 3 dimensional space. The volume of the considered cylinder whose radius is of 3 units, and height of 6 units is V = 54π cubic units.
What is the volume of a cylinder?Suppose that the radius of considered cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
For this case, we're specified that:
Radius of the considered cylinder = r = 3 unitsThe height of the considered cylinder = h= 6 units.Thus, the volume of this cylinder is:
[tex]V = \pi r^2 h = \pi (3)^2 (6) = 54\pi\: \rm unit^3[/tex]
Thus, the volume of the considered cylinder whose radius is of 3 units, and height of 6 units is V = 54π cubic units.

Find the rate of change for f(x)=x^2-8x+15 from x=0 to x=4
Answer:
-4
Step-by-step explanation:
Find the rate of change for f(x) = x² - 8x + 15 from x = 0 to x = 4
The rate of change is the rate at which a variable changes over a specific period of time.
Averate rate of change: [tex]\frac{f(b)-f(a)}{b-a}[/tex]
First, we need to find the functions for when x = 0 and when x = 4:
For x = 0
f(x) = x² - 8x + 15
f(0) = 0² - 8(0) + 15
f(0) = 0 - 0 + 15
f(0) = 15
For x = 4
f(x) = x² - 8x + 15
f(4) = (4)² - 8(4) + 15
f(4) = 16 - 32 + 15
f(4) = -16 + 15
f(4) = -1
Averate rate of change: [tex]\frac{f(b)-f(a)}{b-a}[/tex]
A = [tex]\frac{f(4)-f(0)}{4-0}[/tex]
A = [tex]\frac{-1-15}{4-0}[/tex]
A = [tex]\frac{-16}{4}[/tex]
A = [tex]-4[/tex]
Therefore, the rate of change from x = 0 to x = 4 is -4.

The dimensions of a rectangle are shown. What is the perimeter, in units of the rectangle?
Answer:
the perimeter, in units of the rectangle is 16x + 20
Step-by-step explanation:
perimeter of a rectangle be is 2(L + B)
p = 2(L + B)
L = 5x + 2
B = 3x + 8
p = 2L + 2B
p = 2(5x + 2) + 2(3x + 8)
p = (10x + 4) + (6x + 16)
p = 10x + 4 + 6x + 16
Collect like terms
p = 10x + 6x + 4 + 16
p = 16x + 20
Answer: 16x+20
Step-by-step explanation:
perimeter of a rectangle is the length of all sides added together.
(3x+8)+(3x+8)+(5x+2) + (5x+2)

Answer:
finding the area:
146
Step-by-step explanation:
You need to break the image up into 3 pieces. the lower big triangle, the middle square, and the top triangle.
the measuremets of the lower big triangle is 14 and 14.
to find the area, we need to do 1/2 *14*14
this equals 98
The measurements of the square is 4,4.
we multiply 4*4 to get 16
The measurements of the top triangle is 8,8.
We find the area by doing 1/2*8*8
We get 32
lastly, we add up all of our solutions.
we do 98+16+32
we get 146.

(1) (x - 5)² + (y + 4)² = 14
(2) (x - 5)2 + (y + 4)² = 49
(3) (x + 5)² + (y — 4)² = 14
(4) (x + 5)² + (y - 4)² = 49
Answer:
Option D
Step-by-step explanation:
Given:
Center point: (-5, 4)Radius: 7Formula:
Equation of circle: (x - h)² + (y - k)² = r²
[Where (h, k) is the center point and "r" is the radius of the circle]
Substitute the coordinates of the center point in the formula:
Given center point: (-5, 4)
∴ x-coordinate of center point (h) = -5; y-coordinate of center point (k) = 4
⇒ (x - h)² + (y - k)² = r²⇒ [x - (-5)]² + [y - 4]² = r²Substitute the radius in the formula:
Given radius: 7
⇒ [x - (-5)]² + [y - 4]² = r²⇒ [x - (-5)]² + [y - 4]² = (7)²Simplify both sides of the equation:
⇒ [x + 5]² + [y - 4]² = (7)(7)⇒ [x + 5]² + [y - 4]² = 49 (Option D)Therefore, Option 4 is correct.

Which expression is equivalent to -3x+9?
A.-3(x+9)
B.-3(x-3)
C.-3(x+12)
D.3(-x-3)
Explanation:
Use the distributive property to pull out the -3
When going in reverse like this, we divide each term by -3
-3x/(-3) = x
9/(-3) = -3
So -3x+9 = -3(x-3)
We can verify this by multiplying the -3 outside with each term inside
-3 times x = -3x
-3 times -3 = 9
This shows how -3(x-3) turns into -3x+9 again.

Which of the following represents the linear form of v?
v= -6i -8j
v= -8i-6j
v= 6i +8j
v= 8i +6j
Answer:
v = -8i - 6j
Step-by-step explanation:
The starting point is (9, 9)
The direction of the vector is the direction of the arrowhead.
The i is the horizontal component.
The j is the vertical component.
Therefore, to go from the start to the end of the line, we need to travel negative 8 units (horizontally) and negative 6 units (vertically).
Therefore, v = -8i - 6j
Answer:
(b) v = -8i -6j
Step-by-step explanation:
The unit vectors in the x- and y-directions are i and j, respectively.
The vector v shown in the graph extends from x=9 to x=1, or (1 -9) = -8 units in the x-direction.
It extends from y=9 to y=3, or (3-9) = -6 units in the y-direction.
Represented as a sum of x- and y-vectors, that is ...
v = -8i -6j

way to know if a quadrilateral is a parallelogram is if opposite sides are actually.
Answer:
I believe the answer is probably parallelogram because it is undetified if it is equivalent on the sides or not. If the sides were equal it would be an isosceles trapezoid and if they weren't it would be a trapezoid. Since there is not enough info about the side legnths of the figure it would more than likely be a parallelogram.
