Answer: $16.80

Step-by-step explanation:

The disinfecting wipes cost $12 for the store to buy one.

They then add a 40% mark up.

Find out what 40% of $12 is:

= 40% * 12

= $4.80

Add the markup to the cost to find the selling price:

= 12 + 4.80

= $16.80

Answer:

A)  2

B)  0

C)  1

Step-by-step explanation:

Firstly this shape is an triangle and a triangle has 3 sides/ angles and all angles sum up to 180 degrees...

E = 90 degrees

This explains that it is an hypotenuse triangle so...

answer:

= 39x39 = 1521

= 89x89 = 7921

= 1521 + 7921 = 9442

= square root of 9442 = 97.169954204 rounded off to 97.2

97.2 degrees!

[tex]b(b+7)(b-7)[/tex]

Step-by-step explanation:

Start by factoring a [tex]b[/tex] out:

[tex]b(b^2-49b)[/tex]

For the term [tex]b^2-49b[/tex], we're looking for two numbers that add up to 0 and multiply to be -49:

[tex]7+(-7)=0,\\7\cdot -7=-49\\[/tex]

Two numbers: [tex]7\text{ and }-7[/tex]

Therefore, we have:

Answer:

x = 20

y = 20√2  

Step-by-step explanation:

This is a 45 - 45 - 90° special right triangle

In a 45 - 45 - 90° triangle the legs are congruent and the hypotenuse = leg * √2

If one leg = 20 then the other leg also = 20

Thus, x = 20

If leg = 20

Then hypotenuse = 20 * √2 or 20√2

Thus, y = 20√2

Answer:

43

Step-by-step explanation:

Inscribed Angle = 1/2 Intercepted Arc

< MQP = 1/2 ( 86)

< MQP = 43

Answer:

43°

Step-by-step explanation:

The measure of an inscribed angle is half the measure of the arc it subtends.

m<Q = (1/2)m(arc)MP

m<Q = 1/2 * 86°

m<Q = 43°

Answer:

but where is the diagram

Elena drops her pencil into her cup and notices that it just fits diagonally. The pencil is 17 cm long and the cup is 15 cm tall. The diameter of the cup is 8 cm.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

Elena drops her pencil into her cup and notices that it just fits diagonally. The pencil is 17 cm long and the cup is 15 cm tall.

Consider the pencil and cup just make a right angle triangle. If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2 \\\\|17|^2 = |15|^2 + |BC|^2 \\\\289 = 225 + |BC|^2 \\\\ |BC|^2 = 289 - 225\\\\ |BC|^2 = 64\\\\ |BC|^2 = \sqrt{64} \\\\BC = 8[/tex]

Answer:

Age of son = 6 years

Age of man = 5×6 = 30 years

Step-by-step explanation:

GIVEN :-

TO FIND :-

SOLUTION :-

Let the present age of son be 'x'.

⇒ Present age of man = 5x

4 years ago ,

Age of son = (Present age of son) - 4 = x - 4

Age of man = (Present age of man) - 4 = 5x - 4

The man was thirteen times as old as his son. So,

[tex]=> 5x - 4 = 13(x - 4)[/tex]

Now , solve the equation.

[tex]=> 5x - 4 = 13x - 52[/tex]

[tex]=> 13x - 5x = 52 - 4[/tex]

[tex]=> 8x = 48[/tex]

[tex]=> \frac{8x}{8} = \frac{48}{8}[/tex]

[tex]=> x = 6[/tex]

CONCLUSION :-

Age of son = 6 years

Age of man = 5×6 = 30 years

Answer:

c = 13

Step-by-step explanation:

1. Pythagorean theorem states that c^2 = a^2 + b^2

2. In this case, a = 5, b = 12. Therefore, the equation is:

c^2 = 5^2 + 12^2

3. c^2 = 25+144 = 169

4. square root both sides

5. c = 13, c = -13

6. c = 13 since a length cannot be negative.

7. Final answer: C = 13

Tyler's wedge is larger

The arc length of Priya's wedge is only 9.42, and Tyler's is 12

Tayler's wedge is larger.

"Arc length is the distance along the part of the circumference of any circle."

S = 2 × π × r

where, r is the radius of the radius of a circle

In this question,

Tyler bought a wedge shaped cheese with arc length 12 cm and radius 8 cm.

Priya bought a wedge that came from a circular cheese block with radius 9 cm and the block was cut into 6 congruent sectors.

The circumference of circular cheese block with radius 9 cm would be,

⇒ s = 2 × π × 9

⇒ s = 18π cm

Since, the block was cut into 6 congruent sectors.

The arc length of each block would be, 18π / 6 = 3π cm

That is, 9.43 cm

Since 12 > 9.43, Tayler's wedge is larger.

Area of equilateral triangle = 81√3 cm²

Step-by-step explanation:

Given:

Perimeter of an equilateral triangle = 54 cm

Find:

Area of equilateral triangle

Computation:

Perimeter of an equilateral triangle = 3 x Side

54 = 3 x Side

Side of equilateral triangle = 54 / 3

Side of equilateral triangle = 18 cm

Area of equilateral triangle = [√3/4]side²

Area of equilateral triangle = [√3/4][18]²

Area of equilateral triangle = [√3/4][324]

Area of equilateral triangle = [√3][81]

Area of equilateral triangle = 81√3 cm²

Answer:

The mode of the data sets

Step-by-step explanation:

The measure of central tendency is a value that aims to give the description of a data set by providing a pointer to the central position of the data set

The item under comparison = The most common women running shoe color and the most common women sandal color

The characteristics of the items under comparison = Color (nominal characteristic)

Therefore, the measure of central tendency will aim to show the frequency with which particular colors are worn, which is represented by the mode of the data set
