22.50

Step-by-step explanation:

other answer is cryptic so here is a full explaination

To find the regular price of the hat, we need to determine the amount of the discount and then add that amount to the discount price.

The discount on the hat is 20% of the regular price, or 20/100 * regular price. The discount price is $18, so we can set up the equation:

discount price = regular price - (20/100 * regular price)

Substituting the known values into the equation, we get:

$18 = regular price - (20/100 * regular price)

Solving for the regular price, we find that the regular price is $22.50. This is the price of the hat before the discount.

Answer:

[tex] \sf \: x = 25[/tex]

Step-by-step explanation:

Given equation,

→ (x - 7)2 = 36

Now the value of x will be,

→ 2(x - 7) = 36

→ (2 × x) - (2 × 7) = 36

→ 2x - 14 = 36

→ 2x = 36 + 14

→ 2x = 50

→ x = 50/2

→ [ x = 25 ]

Hence, the value of x is 25.

Answer:

x = 25

Step-by-step explanation:

(x-7)2 = 36

divide both sides by 2

x-7 = 18

add 7 to both sides

x = 25

The range of the function f(x) = |x| + 7 is given by the option presented as follows:

7 ≤ y < ∞.

The range is composed by the set containing all the values assumed by the output of the function, that is, all the numeric values assumed by the function.

In the context of this problem, the function is defined as follows:

f(x) = |x| + 7.

The parent function is the absolute value function g(x) = |x|, which gives the distance of a point x from the origin, assuming real values of at least 0, as a distance cannot be negative.

The addition by 7 means that the parent function was translated up seven units, meaning that the minimum value assumed by the range is seven, and the range of the function is given by the last option given as follows:

7 ≤ y < ∞.

 We need to determine the probability of 5 years survived persons from drug assigned

Let, it is denoted by P(Sr/Dr)

As per conditional probability P(Sr/Dr) = P(Sr and Dr)/P(Dr)

                                                               = 101/344

Using a ruler and compass, draw a line through point A parallel to line PQ by first drawing a line segment from A to any point on PQ. Then, use the compass to draw an arc from the other end of the line segment to the other point on PQ. Finally, use the ruler to draw a line through the arc, parallel to PQ.

Drawing a line parallel to an existing line can be done using a ruler and compass. First, draw a line segment from point A to any point on line PQ. Then, use the compass to draw an arc from the other end of the line segment to the other point on PQ. This arc should intersect with the first line segment. Finally, use the ruler to draw a line through the arc, parallel to PQ. This line will be parallel to PQ since it is the same distance from each point on the original line. The use of the compass ensures that the resulting line is the same distance away from the original line throughout, thus resulting in a line parallel to PQ.

To determine the input number, we can use the following steps:

Calculate the change in the input number as a percentage of the input number. In this case, the input number decreased by 15%, so the change is -0.15 * input number.

Add the change to the output number to find the input number. In this case, the output number is 50, so the input number is 50 + (-0.15 * input number).

Solve for the input number. In this case, we can solve for the input number by rearranging the equation and solving for x:

input number = 50 / (1 - 0.15)

input number = 50 / 0.85

input number = 58.82

Therefore, the input number is 58.82.

Note that this process can also be used to determine the output number given the input number and the percentage change. For example, if the input number is 100 and it increases by 85%, the output number would be:

output number = 100 * (1 + 0.85)

output number = 100 * 1.85

output number = 185

Answer:

[tex]x \times \frac{85}{100} \times \frac{185}{100} = 50[/tex]

Its been a minute since I've done this math

Step-by-step explanation:

This statement demonstrates the substitution property.

The substitution property states that if two expressions are equal, then we can substitute one expression for the other in any equation or inequality. In this case, "A" is an acute angle, and "m2A" is the measure of twice that angle. The statement says that if we double the measure of an acute angle, the result will be 30 degrees. Therefore, we can substitute "m2A" for 30 degrees in any equation or inequality.

The reflexive property states that any number or object is equal to itself. The symmetric property states that if a = b, then b = a. The transitive property states that if a = b and b = c, then a = c. None of these properties are demonstrated in the given statement.

The polynomial p(x) must have at least two zeros, since it has three relative extrema.

What is polynomial?

A polynomial is a mathematical statement made up of coefficients and indeterminates that uses only the operations addition, subtraction, multiplication, and powers of positive integers of the variables. x²- 4x + 7 is an illustration of a polynomial with a single indeterminate x.

Here i would think that since there are only 3 critical points given and no other information other than that those are the only critical points that p(x) would not have any real zeros.

At each of the relative extrema, the value of the function changes from increasing to decreasing or vice versa, meaning that the function crosses the x-axis at that point, which is a zero. Therefore, p(x) must have at least two zeros.

The evaluation is 10.67 of given geometric progression.

A geometric progression is a set of elements where each succeeding element is created by multiplying the one before it by a number called the common ratio. The standard representation for a geometric progression series is a, ar, ar²,..., where an is the first term and r is the common ratio of the sequence.

The ratio between two consecutive numbers, or a number divided by the number before it in the sequence, is known as the common ratio since it is the same for all numbers or common.

The sum of a finite geometric series can be found using the formula:

[tex]a (1-r^{n}) / (1-r)}[/tex].

Where a is the first term and r is the common ratio between successive terms.

To find the ratio of successive terms by plugging into the formula

r = aₙ +1 / (aₙ)

Simplifying,

r =1/4

And the first term is;

when n=1, a = 8

Substituting all the values to the formula,

The summation of GP

= 8 x { 1 - (1/4)¹⁰ } / {1- (1/4)}

= 8 { 1 - (1/1048576) / (3/4)

= 8 x {(1048576 - 1) / 1048576} x (4/3)

= 8 x (1048575 / 1048576) x (4/3)

Step-by-step explanation:

You have parallelogram MNPR with diagonals that cross at E, and ME = 7x-30, and PE = 5x-12. You want to know the length of MP.

The diagonals of a parallelogram bisect each other this means point E is the midpoint of diagonal MP, and ...

  ME = PE

  7x -30 = 5x -12

  2x = 18 . . . . . . . . . add 30-5x

  x = 9

Then the length of the half-diagonal is ...

  ME = 7x -30 = 7(9) -30 = 33

sin2Theta= -4rt21/25

cos2Theta = 17/25

Step-by-step explanation:

Use Double Angle Formulas.

You can find cos2Theta immediately because one of the formulas needs only sin(theta) and that was given.

Cos2Theta =

1 - 2(sinTheta)^2

= 1 - 2(-2/5)^2

= 1 - 2(4/25)

= 1 - 8/25

= 25/25 - 8/25

= 17/25

The only answer with cos2theta=17/25 is the first choice.

Use a simple graph and Pythagorean Theorem to find cos(theta). Then you can use the Double Angle Formula for sin2theta. This would kinda be a double check if you have time. Since the first part of the solution eliminated all choices except the first choice, if you're pressed for time just do cos2theta calculation and pick the first choice.

See image for sin2theta calculation.

If Sue's home is the origin and the positive direction is assumed to the right, then her position is 2 mi.

Therefore, the answer is 2mi.

Origin depends on the frame of reference, it depends on from where the observer is viewing.

From the figure, distance between home and Sue = 2 - 0 = 2mi

and the distance between Cinema and Sue = 5 - 2 = 3mi

Sue's position is 2mi right to her home and 3mi left to the Cinema. So if her home is the origin and positive direction is to the right x is +2 mi.

To find the slope of a line that passes through two points, we can use the slope formula, which is written as follows:

slope = (y2 - y1) / (x2 - x1)

Where (x1, y1) and (x2, y2) are the coordinates of the two points.

Given the points (-7, -2) and (-15, -14), we can substitute their coordinates into the slope formula to find the slope of the line:

slope = (-14 - (-2)) / (-15 - (-7))

= -12 / -8

= 3/2

Therefore, the slope of the line that passes through the points (-7, -2) and (-15, -14) is 3/2. In simplest form, this is equal to 1.5.
