Worth 18 points help

Answer:

$15.96

Step-by-step explanation:

Sales price = $19.95

Discount = 20%

Amount paid = $19.95 - ($19.95*20%) = $19.95 - $3.99 = $15.96

Answer:

$15.96

Step-by-step explanation:

The sales price is $19.95. The discount is 20%.

$19.95 - ($19.95 × 20%)

$19.95 × 20% = $3.99

$19.95 - $3.99 = $15.96

Answer:

4

Step-by-step explanation:

The three angles in a triangle measure 180°. So add the the 2 known angles 70° + 63° = 133. Then subtract it from 180° to get the unknown angle 180 - 133 = 47.

Now that we know the third angle is 47 we find which number that when multiplied by 11 and 3 is added to that number you get 47.

11×4+3 = 47

Therefore l, the answer is 4

Answer:

[tex]x^{2} + 22x + 120[/tex]

Step-by-step explanation:

The ball pit was originally 10 × 12 feet long, or a 120ft area.

We can express the areas of the side and bottom extensions as [tex]12x[/tex] and [tex]10x[/tex] respectively.

The corner adjacent to both extensions can be expressed as [tex]x^{2}[/tex].

We can put these numbers into a polynomial:

[tex]x^{2} + 12x + 10x + 120[/tex]

This polynomial can then be simplified.

[tex]x^{2} + 22x + 120[/tex]

Answer:

x = 61°

y = 61°

z = 58°

Step-by-step explanation:

In the given triangle, measures of two sides are equal. So, measures of angles opposite to them are also equal.

Therefore,

[tex]x + x + 58 \degree = 180 \degree \\ \\ 2x = 180 \degree - 58 \degree \\ \\ 2x = 122 \degree \\ \\ x = \frac{122 \degree}{2} \\ \\ x = 61\degree \\ \\ y = 61\degree \\ ( \angle s \: in \: the \: alternate \: segment) \\ \\ z = 58\degree \\ ( \angle s \: in \: the \: alternate \: segment) \\ [/tex]

Answer:

(d) 16.07

Step-by-step explanation:

Step 1

We find the mean

Formula = Sum of Terms/Number of Terms

= 160+ 215 + 195/3

= 570/3

= 190

Step 2

We find the Standard Deviation

We use the formula for Sample Standard deviation =

√Mean - x/n - 1

n = 3

= √[(160 - 190)² + (215 - 190)² + (195 - 190)²]/3 - 1

= √1550/3

= √775

= 27.83882181

Approximately = 27.84

Step 3

We find the Standard Error of the mean

The formula = Standard deviation/√n

= 27.84/√3

= 16.07

Option d is correct

Based on the information given, the standard error of the mean of these three weights is 16.07.

The mean of the numbers will be:

= (160 + 215 + 195)/3

= 190

The standard deviation will be approximately 27.84.

Lastly, the standard error will be:

= 27.84 × ✓3

= 16.07

Answer:

the greatest possible length of each square plot is 1 ft.

1,269 square plots

Step-by-step explanation:

Since the plots are going to be squares then the width and length need to be the same. This means that the largest size of these plots would be calculated as the largest common divisor of the length and width of the garden. In this scenario, since 47 only has two divisors 1 and 47, and 27 is not divisible by 47 then the GCD of these two numbers would be 1. Meaning that the greatest possible length of each square plot is 1 ft.

To calculate the total number of plots needed we divide the square footage of the garden by the square footage of each individual plot like so...

47 * 27 = 1,269 sq. ft.

1 * 1 = 1 sq. ft.

1,269 / 1  = 1,269 plots

Finally, we see that we need a total of 1,269 square plots to cover that same area of the garden.

Those cities are located on the vertices of the triangle.

The circumcenter of a triangle is the point equidistant from the three vertices of the triangle.

Correct option is D.

Answer:

Incenter

Step-by-step explanation:

1) Since the newest location must be at the same distance from that Triangle's verticles.

2) Then, according to that, the point that it's central and equidistant is the incenter, Because the incenter is at the center of an inscribled circle.

3) Hence, the answer is Incenter.

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If a point A(x, y) is rotated 90° counterclockwise, the new point is at A'(-y, x).

If a point A(x, y) is rotated 90° clockwise, the new point is at A'(y, -x).

If a point A(x, y) is rotated 180° counterclockwise, the new point is at A'(-x, -y).

If a point A(x, y) is rotated 270° counterclockwise, the new point is at A'(y, -x).

Polygon ABCD is defined by the points A(-4, 2), B(-2, 4), C(1, 3), and D(2, 2).

The coordinates of D′ if polygon ABCD rotates 90° counterclockwise to create A′B′C′D′ is D'(-2, 2)

The coordinates of C″ if polygon ABCD rotates 90° clockwise to create A″B″C″D″ is C"(3, -1).

the coordinates of A′′′ if polygon ABCD rotates 180° clockwise to create A′′′B′′′C′′′D′′′ is A''"(4, -2)

Divide each side by 12:

12x ÷ 12 = 110 ÷ 12

x = 110 ÷ 12

x = 9 and 1/6
