Answer: 9

Step-by-step explanation:

Volume of cone formula is: pi r^2 h/3

So pi x 8^2 h/3 = 603

H/3 = 2.9991

h = 9 (rounded)

Answer:

Step-by-step explanation:

The anwser is 479 - 2:5 as a decimal is .4 , 342 x .4 is 126.8

342+126.8 = 178.8

round it and get 479

By using given ratio, Members does the club have are 1197.

"A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one."

We have,

Ratio of health club members who use trainers and who do not  is 2:5.

Members who use trainers = 342

Members who does not use trainers

= [tex]\frac{342}{2}[/tex]×[tex]5[/tex]

= 171 × 5

= 855

Total members

= 855 + 342

= 1197

Hence, Members does the club have are 1197.

answer: Which angle? It doesn't say which.

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

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:

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

Answer:

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:

m∠N = 32°

NQ = 106°

When finding inscribed angles like ∠N with the intercepted arc, the equation is ∠N=1/2MP. (Inscribed angles are always half the degree of the arc length.) Plug in the corresponding value to get ∠N=1/2(64) to get 32°. When finding the angle of the intercepted arc with inscribed angles like NQ, the equation is NQ=2(∠P). Plug in the corresponding value to get 2(53) to get 106°.

Answer:

x-int = (-40,0)

y-int = (0,15)

Step-by-step explanation:

:D

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°
