Answer:

These numbers are not the same as 4/9 is bigger than 2/5.

Step-by-step explanation:

As we have to compare the decimal forms of 2/5 and 4/9.

We determine that the numbers in decimal forms are:

[tex]\frac{2}{5}=0.4[/tex]

[tex]\frac{4}{9}=0.44444...\:[/tex]

so

[tex]\frac{4}{9}=0.44444[/tex] is clearly bigger than [tex]\frac{2}{5}=0.4[/tex].

Therefore, these numbers are not the same as 4/9  is bigger than 2/5.

Answer:

The probability is 2/9

Step-by-step explanation:

Here , we want to find the probability of getting a violet ball first and a pink ball secondly if the violet ball is replaced

probability = number of balls of same color/total number of balls

The total number of balls = (2 + 4) = 6 balls

Probability of selecting a violet = 2/6 = 1/3

Probability of selecting a pink afterwards with replacement = 4/6 = 2/3

So the probability of selecting the balls in that order will be;

1/3 * 2/3 = 2/9

Responder:

Número total de bolas = 245/23

Explicación paso a paso:

Dado que:

Bolas blancas = 1/5

Bolas negras = 1/7

Bolas rojas = 7

Sea el número total de bolas = x

Bolas blancas = 1 / 5x

Bolas negras = 1 / 7x

Por tanto, total;

(x / 5 + x / 7 + 7) = x

((7x + 5x) / 35) +7 = x

(12x / 35) + 7 = x

7 = x - 12x / 35

7 = (35x - 12x) / 35

7 = 23 veces / 35

245 = 23x

x = 245/23

Answer:

23 cents per ounce

0.23  

3.22/ 14 = .23 per oz.

Answer:

39.00%

Step-by-step explanation:

Given

Dimension: 36⅞ by 19 by 24⅝

Volume of Water = 6039in³

Required

What percent of the volume of the aquarium is filled with water?

First, we need to calculate the volume of the aquarium.

This is calculated by multiplying the dimensions of the aquarium

Volume = 36⅞ * 19 * 24⅝

Volume = 295/8 * 19 * 197/8

Volume = 1104185/64

Volume = 17252.89

The percent filled with water is calculated using the following formula:

%Percent = (Volume of water * 100%)/(Volume of aquarium)

%Percent = (6039 * 100%)/(17252.89)

%Percent = (603900%)/(17252.89)

%Percent = 39.00% (approximated)

Hence, the water occupies 39.00% of the aquarium

Answer:

The force the player hit the ball with is 900 N

Step-by-step explanation:

Given;

mass of the baseball, m = 0.75 kg

acceleration of the ball, a = 1200 m/s²

The force the player hit the ball with is given by the following equations;

F = ma (based on Newton's second law of motion)

where;

F is the applied force

m is mass of the baseball

a is the acceleration of the baseball

F = ma

F = (0.75 x 1200)

F = 900 N

Therefore, the force the player hit the ball with is 900 N

Answer:

∠ACB≅∠CAD, Alternate Interior Angles Theorem

∠BAC≅∠DCA, Alternate Interior Angles Theorem

AC≅AC, Reflexive Property of Congruence

By A-S-A congruence, the △ABC≅△CDA.

Step-by-step explanation:

Given the figure:

We are given that:

Side BC || AD

Side AB || DC

Let us have a look at a few properties first.

Alternate Interior Angle Theorem: It states that when two parallel lines are cut by a line then the alternate angles which are on the interior side are equal to each other.

Reflexive Property of Congruence: It states that a side or angle is always congruent to itself.

Now, let us consider the triangles:

△ABC and △CDA.

Side BC || AD

Therefore,

∠ACB≅∠CAD, Alternate Interior Angles Theorem

Side AB || DC

Therefore,

∠BAC≅∠DCA, Alternate Interior Angles Theorem

Also, Side AC is common.

AC≅AC, Reflexive Property of Congruence

Therefore, by A-S-A congruence, the △ABC≅△CDA.
