I don’t know how to solve for p.
Answer:
p=12
Step-by-step explanation:
DBC = 180
ABE = 180
ABC + DBA = 180
ABC = (5p -28)
DBA + (12p -4)
CBD = ABC + DBA = 180
-------------------------------------------------
180 = (5p - 28) + (12p + 4)
180 = 17p - 24
204 = 17p
12 = p
p = 12
------------------------------------------------------
180 = (5(12) - 28) + (12(12) +4)
180 = 60 - 28 + 144 +4
180 = 180

Sneha works two part-time jobs. One job is at a tutoring company that pays $19 an hour, and the other is pumping gas for $11.50 an hour. Between the two jobs, Sneha wants to earn at least $310 a week. Let x be the number of hours she works at the tutoring company and let y be the number of hours she works pumping gas. Write an inequality that models this situation.
Answer:
[tex]19x + 11.5y \geqslant 310[/tex]
19x+11.5≥310 is the inequality that models this situation.
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
Given that Sneha works two part-time jobs
One job is at a tutoring company that pays $19 an hour,
Let x be the number of hours she works at the tutoring company
The other is pumping gas for $11.50 an hour
let y be the number of hours she works pumping gas.
Sneha wants to earn at least $310 a week
We have to find the inequality that models this situation.
19x+11.5≥310
Hence, 19x+11.5≥310 is the inequality that models this situation.

The difference of a number x and 15 is no less than 11
Answer:
x = 4; 15 - x > 11
Step-by-step explanation:
Step 1: set up equation

- x = 11 - 15
- x = - 4
x = - 4 ÷ - 1
x = 4
For inequality:

A man walks (12x^2+11x+2) km for (3x+2) hours. What is his speed per hour?
Step-by-step explanation:
Hey there!
Distance = 12x^2+11x+2.
And Time = 3x+2 hours.
Now;
[tex]speed = \frac{distance}{time} [/tex]
Put all values.
[tex]s = \frac{12 {x}^{2} + 11x + 2}{3x + 2} [/tex]
Use mid term factorization is numerator and simplify them to get answer.
[tex]s = \frac{12 {x}^{2} + (8 + 3) x+2 }{3x + 2} [/tex]
[tex]s = \frac{12 {x}^{2} + 8x + 3x + 2 }{3x + 2} [/tex]
[tex]s = \frac{4x(3x + 2) + 1(3x + 2)}{(3x + 2)} [/tex]
[tex]s = \frac{(4x + 1)(3x + 2)}{(3x + 2)} [/tex]
[tex]s = (4x + 1)[/tex]
Therefore the speed is (4x+1)/hr.

What is the distance for A(6,0), B (-4,5)
Answer:
[tex]5\sqrt{5}[/tex]
Step-by-step explanation:
The distance formula states that [tex]D(x_{1} ,y_{1})(x_{2},y_{2} )=\sqrt{(x_{2} } -x_{1} )^2+(y_{2}-y_{1} )^2\\[/tex]
We plug in our points, (6,0) and (-4,5), and compute.
[tex]\sqrt{(-4-6)^2+(5-0)^2} \\\sqrt{(-10)^2+5^2} \\\sqrt{100+25} \\\sqrt{125} \\5\sqrt{5}[/tex] (Make sure you see why I put parentheses around the -10 in (-10)^2. -x^2 and (-x)^2 are not the same) (Also here is why the simplification of the radical works)
[tex]\sqrt{125} =\sqrt{5^2*5} =\sqrt{5^2} *\sqrt{5} =5*\sqrt{5} =5\sqrt{5}[/tex]

how do you express a number as a power of 3?
9514 1404 393
Answer:
the power of 3 is the log, base 3, of the number
Step-by-step explanation:
The relationship between powers and logarithms is ...
y = 3^x
x = log₃(y) = log(y)/log(3)
__
For example, if you want 5 as a power of 3, that power will be ...
log(5)/log(3) = 0.69897/0.47712 = 1.46497
That is, ...
5 = 3^1.46497
(a + b)(a 2 - ab + b 2)
Answer:
a³ + b³
Step-by-step explanation:
Given
(a + b)(a² - ab + b²)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a² - ab + b²) + b(a² - ab + b²) ← distribute both parenthesis
= a³ - a²b + ab² + a²b - ab² + b³ ← collect like terms
= a³ + b³
Answer:
a^3 + b^3 ("the sum of two cubes")
Step-by-step explanation:
If you want to express exponentiation please use the symbol " ^ ": a^2.
(a + b)(a^2 - ab + b^2) is a "special product" that you should learn, even though you can multiply out these two factors using the Distributive Property of Multiplication. Remember this: (a + b)(a^2 - ab + b^2) = a^3 + b^3, which is "the sum of two cubes."

What is mean by Cuboid?A cuboid is the solid shape or three-dimensional shape. A convex polyhedron which is bounded by six rectangular faces with eight vertices and twelve edges is called cuboid.
We have to given that;
For large rectangular prism,
Lenght = 24
Width = 16
Height = 8
And, For small rectangular prism,
Lenght = 15
Width = 10
Height = 5
Hence, the surface areas of the large rectangular prisms is,
⇒ SA = 2lw + 2lh + 2hw
⇒ SA = 2 (24 x 16 + 24 x 8 + 8 x 16)
⇒ SA = 2 (384 + 192 + 128)
⇒ SA = 2 (704)
⇒ SA = 1408
the surface areas of the small rectangular prisms is,
⇒ SA = 2lw + 2lh + 2hw
⇒ SA = 2 (15 x 10 + 15 x 5 + 10 x 5)
⇒ SA = 2 (150 + 75 + 50)
⇒ SA = 2 (275)
⇒ SA = 550
Hence, The value of the ratio for the surface areas of the rectangular prisms is,
⇒ 1408 : 550
⇒ 704 : 275

Is this a complementary ,linear pair,vertical or adjacent?
Answer:
adjacent
Step-by-step explanation:
Complementary angles add up to 90 degrees. These two do not. So they are not complementary.
Linear means they add up to 180o. (Same as supplementary). These two do not meet those conditions.
vertical angles are across from each other when two line segments or lines cross. These two do not.
The answer is adjacent. 90 <a+b<180

What is the equation of the line that has a slope of -4 and goes through (-1,6)?
Answer:
y = - 4x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4, thus
y = - 4x + c ← is the partial equation
To find c substitute (- 1, 6) into the partial equation
6 = 4 + c ⇒ c = 6 - 4 = 2
y = - 4x + 2 ← equation of line
Answer:
y = - 4x + 2

Which statements about the local maximums and minimums for the given function are true? Choose three options. Over the interval [1, 3], the local minimum is 0 Over the interval [2, 4], the local minimum is –8. Over the interval [3, 5], the local minimum is –8. Over the interval [1, 4], the local maximum is 0. Over the interval [3, 5], the local maximum is 0
Answer:
ii) Over the interval [2, 4], the local minimum is at -8
iii) Over the interval [3, 5], the local minimum is at -8
iv) Over the interval [1, 4], the local maximum is at 0
Step-by-step explanation:
The graph of the function is attached below.
The local minimum is the minimum point within a specified range while the local maximum is the maximum within a specified range.
i) We can see from the graph that within [1, 3] the local minimum is at -6, hence the first option is wrong.
ii) Over the interval [2, 4], the local minimum is at -8, hence option 2 is correct
iii) Over the interval [3, 5], the local minimum is at -8, hence option 3 is correct
iv) Over the interval [1, 4], the local maximum is at 0, hence option 3 is correct
v) Over the interval [3, 5], the local maximum is at infinity, hence option 5 is not correct

find the number of sides in a polygon if the sum of its interior angle is 900 degree
Answer:
The answer is
7 sidesStep-by-step explanation:
The sum of interior angles(s) of a polygon can be found by using the formula
s = (n - 2) × 180Where n is the number of sides of the polygon
From the question
s = 900°
Substitute this value into the above formula and solve for n
That's
[tex]900 = (n - 2) \times 180 \\ 900 = 180n - 360 \\ 180n = 900 + 360 \\ 180n = 1260[/tex]
Divide both sides by 180
[tex] \frac{180n}{180} = \frac{1260 }{180} \\ [/tex]
We have the final answer as
n = 7
Therefore the polygon has 7 sides

20. Two collinear rays that do not intersect? How would I draw this?
Answer:
Two collinear rays are parallel to each other.
Step-by-step explanation:
Two collinear rays parallel to each other, and they are on the same plane. Thus they do not meet even when extended till infinity.
An example of collinear rays is when you draw two parallel rays on a plain paper placed on an horizontal surface.
Your drawing should look like what is attached to this answer.
Yes, two collinear rays that do not intersect along with the figure attached at he end.
To draw two collinear rays that do not intersect, you can follow these steps:
1. Start by drawing a straight line segment. This will be the common line for the collinear rays.
2. Choose a point on one end of the line segment. This will be the starting point of the first ray.
3. Draw a line extending from the chosen point, in the same direction as the line segment, but do not let it intersect the line segment.
4. Choose another point on the other end of the line segment. This will be the starting point of the second ray.
5. Draw a line extending from the second point, also in the same direction as the line segment, but make sure it does not intersect the line segment or the first ray.
