Answer:

164 cubic units

Step-by-step explanation:

volume of a sphere = (4/3) x (n) x (r^3)

If volume = 4r^3

volume = 4 x (4)^3 = 164 cubic units

8

Step-by-step explanation:

2 * 8 = 16

Answer:

It is equivalent to w+w

Step-by-step explanation:

w+w= 2w

Answer:

A w+w

Step-by-step explanation:

because 2w means 2 * w ( 2 times w)

when you multiply 2 time any number, you add that number twice,

exp... 4 times 2 = 4 + 4

therefore 2w is also w+ w

Answer:

1 ladrillo cuesta 1 dólar.    1 brick costs 1 dollars.

1 kg de cemento cuesta 3 dólares: 1 kg cement costs 3 dollars

1 kg de arena cuesta $ 16: 1 kg sand costs $ 16

Step-by-step explanation:

Spanish

Deje que los ladrillos, la arena y el cemento se denoten por b, sy c. Luego, de acuerdo con la condición dada

20b + 5s + 10c = $ 130 --- ecuación 1

1c = 3b ------ ecuación 2

1s = 4c + 4b ------ ecuación 3

Poniendo la ecuación 2 en la ecuación 3

1s = 4 (3b) + 4b

1s = 16b ---------- ecuación 4

20b + 5s + 10 (3b) = $ 130

50b + 5s = 130 --- ecuación 5

Poniendo la ecuación 4 en la ecuación 5

50 b + 5 (16b) = 130

50 b + 80b = 130

130 b = 130

b = 130/130 = $ 1 ------- ecuación a

1 ladrillo cuesta 1 dólar.

Poner el valor de costo de 1 ladrillo en estas ecuaciones

1c = 3b ------ ecuación 2

1s = 4c + 4b ------ ecuación 3

1c = 3 (1) = $ 3 -------- ecuación b

1 kg de cemento cuesta 3 dólares

1s = 4c + 4b

1 s = 4 (3) + 4 (1)

1 s = 12 + 4

1s = $ 16 ------ ecuación c

1 kg de arena cuesta $ 16

Poner valores de la ecuación a, b, c en la ecuación 1

20b + 5s + 10c = $ 130

20 (1) + 5 (16) + 10 (3) = 130

20 + 80 + 30 = 130

130 = 130 ------------ por lo tanto probado

English

Let the bricks , sand and cement be denoted by b, s and c. Then according to the given condition

20b+ 5s+ 10c= $130--- equation 1

1c= 3b------ equation 2

1s= 4c+4b------ equation 3

Putting equation 2 in equation 3

1s= 4(3b) + 4b

1s= 16b---------- equation 4

20b+ 5s+ 10(3b)= $130

50b + 5s= 130--- equation 5

Putting equation 4 in equation 5

50 b + 5 (16b) = 130

50 b+ 80b= 130

130 b= 130

b= 130/130= $1------- equation a

1 brick costs 1 dollars.

Putting the cost value of 1 brick in these equations

1c= 3b------ equation 2

1s= 4c+4b------ equation 3

1c= 3(1)= $3-------- equation b

1 kg cement costs 3 dollars

1s= 4c+4b

1s= 4(3) + 4(1)

1s= 12+4

1s= $16 ------ equation c

1 kg sand costs $ 16

Putting values from equation a, b, c in equation 1

20b+ 5s+ 10c= $130

20 (1) + 5 (16) + 10 (3)= 130

20 + 80 + 30 = 130

130 = 130   ------------ hence proved

Answer: ur correct

Step-by-step explananation

Answer:

8.8 kilograms

Step-by-step explanation:

Answer: 83.6 Kg

Step-by-step explanation:

x * 0.1 = y ---> x = y/0.1

88 - y = x

y/0.1 = 88 - y

2y = 88 * 0.1

y = 4.4

88 - 4.4 = 83.6Kg

Answer:

2,320

Step-by-step explanation:

4.2% gets taken every year and there is 10 year,so 4.2% s uqual to 0.042,so just mutiply 4000 by 0.042 which  is 168,then times 168 by 10 which brings you to 1680 and 4000 subtracyed by 1680,which equals 2,320

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

7(p+2)=5(p+4)

By distributive law

The eqn becomes :

7p + 14 = 5p + 20

collecting like terms ;

7p - 5p = 20 - 14

=> 2p = 6 and

:- P = 3 ( dividing both sides by 2)

P= 3 is the only solution to the equation above and it satisfies the equation.

Answer:

The answer to each question is:

Step-by-step explanation:

A.) To obtain the area of the dodecagon, you can use the next formula:

In the exercise, we have the edge (6 cm), but, to find the apothem of a dodecagon, that is the distance between the center of the polygon, and the middle point of each side, you can use the next formula:

If we replace the value of the edge, we obtain:

With this data, we can find the area:

Then, the area of the dodecagon is 403.2 [tex]cm^{2}[/tex] approximately.

B.) As the area obtained is for 12 pieces, when the parents ate 9 pieces, just left 3 pieces, with these values you can make a rule of three.

If:

Then:

In this form, when the cookie has 3 pieces, its area is 100. 8 [tex]cm^{2}[/tex] approximately.

Volume = 26 cubic meters

Answer:

(A) 33 1/3%

Step-by-step explanation:

it looks like there are 15 total people, and it's asking for the probability of a member over 40 being chosen.

Over means that 40 should be excluded

there are 5 people over 40 (43, 45, 50, 54, 58), which means the probability would be 5/15

5/15 = 1/3 ≈ 33 1/3%

Answer:

28 = h 9 + 23

Answer:

The circumference of the yellow circle is [tex]9\pi[/tex] or [tex]28.27cm^2[/tex] approximately, the circumference of the blue circle is [tex]6\pi[/tex] or [tex]18.85m^2[/tex] approximately, the circumference of the green circle is [tex]80\pi[/tex] or [tex]251.33mm^2[/tex] approximately, the circumference of the red circle is [tex]5\pi[/tex] or [tex]15.71cm^2[/tex] approximately, and the circumference of the pink circle is [tex]7\pi[/tex] or [tex]21.99cm^2[/tex] approximately.

Step-by-step explanation:

To find the circumference of a circle, you need to multiply the diameter of the circle and multiply it by [tex]\pi[/tex]. In this case, the circumferences of the yellow circle are [tex]9\pi[/tex] or approximately [tex]28.27cm^2[/tex], the circumference of the blue circle is [tex]6\pi[/tex] or approximately [tex]18.85m^2[/tex], the circumference of the green circle is [tex]80\pi[/tex] or approximately [tex]251.33mm^2[/tex], the circumference of the red circle is [tex]5\pi[/tex] or approximately [tex]15.71cm^2[/tex], and the circumference of the pink circle is [tex]7\pi[/tex] or approximately [tex]21.99cm^2[/tex].

Answer:

To find the circumference of a cylinder, you have to be aware that a cylinder's cross-section is a circle. If you know the cylinder's radius: Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That's it; you found the circumference of the cylinder.
