Un productor agricola tiene que envasar huevos en cajas de 12, de 6 o de 30. Si sabemos que tiene un numero parecido a 1000 huev
musickatia [10]

Answer:

El productor tiene que envasar 960 huevos.

Step-by-step explanation:

Es necesario determinar el mínimo común múltiplo de 6, 12 y 30. En primer lugar, se determina cada número como productos de números primos:

6 = 2\times 3

12 = 2^{2}\times 3

30 = 2\times 3\times 5

El mínimo común múltiplo es:

M.C.M. = 2^{2}\times 3\times 5

M.C.M. = 60

El número total de huevos próximo a 1000 unidades es un múltiplo del mínimo común múltiplo:

n = 60\times 16

n = 960

El productor tiene que envasar 960 huevos.

Tests show that the hydrogen ion concentration of a sample of apple juice is 0.0003 and that of ammonia is 3.1 x 10^-9. Find the
scoundrel [369]
PH can be calculated using the following equation 
pH = -log [H₃O⁺]
for apple juice the hydronium /hydrogen ion concentration is 0.0003
pH = -log (0.0003)
pH = 3.5
correct answer is C

For ammonia 
pH = -log (3.1 x 10⁻⁹)
pH = 8.5 
answer should be 8.5

A Storage shed has the shape of an upside down cone. The shed has a volume of 209 cubic meters and is 10 meters wide. To the nea
Mrrafil [7]

Answer:

Height = 8 meters

Step-by-step explanation:

Given that

The volume V = 209 cubic meters Diameter = 10 meters

Radius r = 5 metres

How tall is the shed? The question is looking for the height of the cone

Using the formula for volume of a cone.

V = 1/3πr^2h

Where π = 3.14

209 = 1/3 × 3.14 × 5^2 ×h

209 = 3.14/3 × 25h

209 = 78.5h/3

h = 7.99 meters

h = 8 meters

Therefore, the shed is 8 meters tall.

Plzzzz I will give you 100 points plzzz
kirza4 [7]

Answer: x < 8/9


Step-by-step explanation:

The equation is 4 * (2x +1) * 4.5 = 50, since the volume is found by multiplying the length, width, and height together, and the =50 part is because our volume can't go above 50 cubic units.


We can simplify 4 * (2x+1) * 4.5 by multiplying 4 and 4.5, which is 18, and then multiplying both 2x and 1 by 18. We get 36x + 18, and we put in the =50, so it is 36x+18=50.

Next, we can subtract 18 from both sides of the equation, giving us 36x = 32.

We then divide the equation by 36 so that we have the x by itself, and we get x = 32/36, which can be simplified to 8/9.


What we're left with is x = 8/9, meaning plugging in 8/9 for the equation would give us 50. However the problem says that the volume must be below 50, so our actual answer is x < 8/9.

A coin is flipped twice. What is the probability that the coin will land on tails on the first flip and will land on tails again
bixtya [17]

Answer:

1/4=0.25=25%

Step-by-step explanation:

A coin has two sides, heads and tails, and if you take 100% divided by two you get 50, you want to know what is the probability it will land on tails TWICE so divide 50 by two and you get 25.

1/2=50

1/4=25

0.25 x 100= 25%

hope that helps
