Answer is A because;

Let n be the money, and 21.5% the increase in percentage.

\frac{21.5}{100}=0.215

n (money) + n (money) (0.215) (percentage of n)

if BD is perpendicular to AC M angle DBE equals 2x - 1 + m angle CBE equals 5x - 42 find the value of x​
Paha777 [63]
<h2>Answer:</h2>

<h2>Step-by-step explanation:</h2>

I've drawn a graph in order to a better understanding of this problem. We know that:

BC is perpendicular to AC

∠DBE = 2x - 1

∠CBE = 5x - 42

Let's call the intersection of line BC and AC the point P, so:

∠P=90°

And points B, P and C form the triangle ΔBPC. On the other hand, ∠CBE and ∠PCB are Alternate Interior Angles, so:

∠PCB = ∠CBE = 5x - 42

Moreover:

∠PBC = 2x - 1 - (5x - 42)

∠PBC = 2x - 1 - 5x + 42

∠PBC = -3x + 41

The internal angles of any triangle add up to 180°. Hence for ΔBPC:

90° + ∠PBC + ∠PCB  = 180°

90° - 3x + 41  + 5x - 42  = 180°

2x + 89 = 180

2x = 91

x = 45.5°

The potential energy, P, in a spring is represented using the formula P = kx2. Lupe uses an equivalent equation, which is solved
ella [17]

Original equation is P=kx^{2}

So, kx^{2} =P and

k=\frac{P}{x^{2} }

If we compare this equation with the given options, we can easily find that this matches with the last one k=\frac{p}{2x^{2} } with P = p/2.

Hence, correct option is k=\frac{p}{2x^{2} }.

Students at a private liberal arts college are classified as being freshmen, sophomores, juniors or seniors, and also according
labwork [276]
The total number of possible classifications for the students of this college is found by multiplying 4 (which is the classification for the year level:freshman, sophomore, juniou, senior) and 2 (which is the number of sexes: female and male). So 4 x 2 = 8. There are eight possible classifications, which are:
(Male, Freshman)
(Male, Sophomore)
(Male, Junior)
(Male, Senior)
(Female, Freshman)
(Female, Sophomore)
(Female, Junior)
(Female,Senior)

Vlada [557]

\text{Consider the circle of radius 3.}\\&#10;\\&#10;\text{we need to find the cirumference of the circle.}\\&#10;\\&#10;\text{we know that the circumference of the circle of radius r is given by}\\&#10;\\&#10;\text{circumference}=2\pi r\\&#10;\\&#10;\text{so using this formula, the circumference of the given circle is}

\text{Circumference}=2\pi r\\&#10;\\&#10;=2\pi \times 3\\&#10;\\&#10;=6\pi&#10;\\&#10;\text{so the circumference of the circle is}=6\pi\\&#10;\\&#10;\text{and in decimals, it gives}=6\times 3.14\\&#10;\\&#10;\Rightarrow \text{circumference}=18.84

Hence the circumference of the circle is: 6π  or  18.84 units
