Answer:

3.56 cm

Step-by-step explanation:

<em>Cube</em> is a 3D closed structure in which each adjacent side is perpendicular to each other and every side is equal to each other.

Let the side of cube be $a$ cm.

Please refer to attached image of cube for a clear look and feel of a cube with each side = a units.

Then, volume of cube is given by the formula:

$V = a^3$

Here, we are given that:

$V = 45\ cm^3$

$\Rightarrow a^3 = 45\ cm^3\\\Rightarrow a =\sqrt[3] {45}\\\Rightarrow a ={45}^\frac{1}{3}\\\Rightarrow a = 3.56\ cm$

So, the answer is, Side of each petit four is, $a = 3.56\ cm$ .

Find the missing angles.

Feliz [49]

Answer:

a=30 b=30 c= 75

Step-by-step explanation:

By inferring that all triangles are the same measurments, you can easily knock out A and B since it is the same angle that is labeled 30 degrees.

Now to find C you need to know that all angles of a triangle add up to 180 degrees. You also need to know that both bottom angles are the same angle measurement, indicated by the little circle in the angle.

So, For the middle triangle you can create an equation. 30(which was b) + 2c = 180

Subtract 30 from both sides and you are left with:

2c = 150

Divide by 2 on each side:

c= 75

Leah is 2 less than 3 times Rachel's age. 3 years from now, Leah will be 7 more than twice Rachel's age. How old will Rachel be

Irina-Kira [14]

Answer:

Step-by-step explanation:

Let's call Leah's age l and Rachel's age r. We can write:

l = 3r - 2 (1)

l + 3 = 2(r + 3) + 7 (2)

Substituting (1) into (2) we get:

(3r - 2) + 3 = 2(r + 3) + 7

3r + 1 = 2r + 13

r = 12

In 3 years Rachel will be 12 + 3 = 15 years old.

Alan and his brother both want the last doughnut. Alan makes a bet with his brother to decide who should get the doughnut. Alan

<h2>Answer:</h2>

<em><u>Bet should be placed on Black Cards.</u></em>

<h2>Step-by-step explanation:</h2>

In the question,

We have total 52 cards with us in the deck.

<u>There are two cases of placing the bets,</u>

One, when the card picked is black.

Second, when the card picked is a face card and a value of 10.

So,

Number of Black cards in the deck = 26

Number of Face cards with the value of 10 are = 4 x 3 = 12

So,

The <u>probability of selecting a black card</u> is given by,

$Probability=\frac{26}{52}=\frac{1}{2}$

Also,

<u>Probability of selecting a face card of value 10</u> is given by,

$Probability=\frac{12}{52}=\frac{3}{13}$

Therefore, we can see the probability of picking a black card is more than the probability of selecting a face card of value 10.

<em><u>Therefore, if the bet is placed on black card then there is the best chance to win.</u></em>
