Answer:
The Answer is C
Step-by-step explanation:
Anna draws a angle that intercets at 1
When two straight lines or rays intersect at a shared endpoint, an angle is generated. The exact number of points at which the two rays will intersect is 1. The correct option is C.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
As per the definition of an angle, the point at which the two of the given rays will intersect each other is exactly 1 point.
Hence, the exact number of points at which the two rays will intersect is 1.

How to Crammers Rule to find k in this equation
Answer:
k = -1/2 or 2
Step-by-step explanation:
For equations ...
ax +by +c = 0
dx +ey +g = 0
Cramer's Rule tells you the solutions are ...
x = (-ce +gb)/(ae -db)
y = (-ga +dc)/(ae -db)
In order for these equations to be consistent, the solution for any pair of them must be the same. It is sufficient for us to find 'k' such that the values of x are the same.
__
first and third equations
x = (-1·7 +1·(k+1))/(1·7 -3·(k+1)) = (k -6)/(4-3k)
second and third equations
x = (3·7 +1·5)/(2k·7 -3·5) = 26/(14k -15)
__
For these values to be the same, we must have ...
(k -6)/(4-3k) = x = 26/(14k -15)
(k -6)(14k -15) = (4 -3k)(26) . . . . . cross multiply
14k² -99k +90 = -78k +104 . . . . . simplify
14k² -21k -14 = 0 . . . . . . . . . . . . . put in standard form
7(2k +1)(k -2) = 0 . . . . . . . . factor
The solutions are the values of k that make the factors zero: k=2, k=-1/2.
These equations will be consistent if k = -1/2 or k = 2.

Additional comment
Using our above expression for x, we can find the value of x for the solution x = -1/2 to be ...
x = 26/(14(-1/2) -15) = 26/(-22) = -13/11
The first equation tells us the corresponding value of y will be ...
x +(-1/2 +1)y +1 = 0
y = -2(x+1) = -2(-13/11 +11/11) = 4/11
For k = -1/2, (x, y) = (-13/11, 4/11).
The attached graph shows the solution for k=2.
For k = 2, (x, y) = (2, -1).

If a person charging $36 by a quarter of the hour and worked 6hour and 30 minutes how much will they charge
Answer: 936
Step-by-step explanation:
36 x 4 = 144
$144 = 1 hour of work
so for 6 hours of work, you'd do 144 x 6 = 864
Since 30 minutes is 2 outta 4 quarters, then you'd do 36 x 2 which is 72
so 72 + 864 = 963
So 6 hours and 30 minutes would be $936

A building has a second floor window 27 ft above the ground. A fireman brings his 33 foot ladder to lean against the wall to reach the window.
The reference angle will be the angle formed by the ladder and the ground.
[[Word List: Adjacent, Cosine, Hypotenuse, Opposite, Sine, Tangent]]
(a) In this scenario, the ladder represents the ______ of the triangle.
(b) The height of the window is the ________ side of the triangle
(c) The correct trigonometry ratio to use for this scenario is _______.
(d) The reference angle must be between 70 and 80 degrees for the ladder to be safe to climb. Use trigonometry and solve for the reference angle to the nearest whole degree. Is the ladder safe? (show work)
(e) The ladder is adjustable in 1-foot increments. What length does it need to be in order to be safe according to part D? (show work)
The ladder makes an angle 30 degrees with the ground
Data;
Length of the ladder (hypothenuse) = 30 ft
height of the wall (opposite) = 15 ft
When the ladder reclines on the wall, it forms a right-angle triangle and we can solve it.
Using SOHCAHTOA,
We have the value of hypothenuse and opposite and we can use the sine angle of this triangle.
The ladder makes an angle 30 degrees with the ground.

PLEASE HELP REALLY NEED IT RIGHT NOW WILL GIVE CORRECT WORK WITH ANSWER BRAINIEST Find the area of X and show your work !!
Answer:
x = 6.40
Step-by-step explanation:
The formula to find the area of the rectangle is :
Area = Length × Width
Given that,
Area ⇒ 50
Length ⇒ ( 2x - 5 )
Width ⇒ x
So now we can write an expression like this.
Area = Length × Width
50 = x ( 2x - 5 )
And now we can solve for x.
Let us solve now by using the completing square method.
x ( 2x - 5 ) = 50
2x² - 5x = 50
First divide the whole equation by 2.
x² - 2.5 = 25
x² - 2.5 + 1.5625 = 25 + 1.5625
( x - 1.25 )² = 26.5625
x - 1.25 = ±√26.5625
x - 1.25 = ±5.1538
So,
x = + 5.1538 + 1.25 or x = - 5.1538 + 1.25
x = 6.40 x = -3.90
As we cannot get a negative number as a value for length,
x = 6.40

Miguel eats a meal at a restaurant and leaves a 15 % tip for the server. The cost of the meal without the tip is p dollars. Which expressions represent the total cost, in dollars, of the meal and the tip? Select ALL that apply.
Answer:
B,D, and E
Step-by-step explanation:
it's 15% so it would have to be either as a fraction or decimal answer B is a fraction. And D and E are both decimals so you add your percent to your p which is something.
The expressions A, D, and E represent the total cost of the meal and the tip.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
The cost of the meal plus the tip is equal to the cost of the meal plus 15% of the cost of the meal. It can represent this in several ways:
A. 1.15p
D. p + 0.15p
E. p + 1.15p
All of these expressions represent the total cost of the meal and the tip.
Option B, 100P/15, does not represent the total cost of the meal and the tip.
Option C, p + 15, represents the cost of the meal plus a flat fee of 15 dollars, not 15% of the cost of the meal, so it does not represent the total cost of the meal and the tip.
Therefore, the correct answers are A, D, and E.

What is Trigonometry?The area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).
Given:
As, Cosecant is the reciprocal of sine, so the cosecant of any angle x for which sin x = 0 must be undefined, since it would have a denominator equal to 0. The value of sin (pi) is 0, so the cosecant of pi must be undefined.
Thus, csc(3pi) is undefined
and, the value of The value of cos (pi/2) is 0, so the secant of (pi)/2 must be undefined.

can someone explain to me how to get 338 root 2 as the answer
Answer:
13√2
Step-by-step explanation:
The square root of 338 is expressed as √338 in the radical form and as (338)½ or (338)0.5 in the exponent form. The square root of 338 rounded up to 5 decimal places is 18.38478. It is the positive solution of the equation x2 = 338. We can express the square root of 338 in its lowest radical form as 13 √2.
√338 = √13^2x2 = V13^2 x √2 = 13√2
13√2 = 13 x 239/169 = 239/13 = 18.385
