1.<br> 6 cm<br> 6 cm<br> Find the surface area of the cube.<br> Surface Area = [?] cm²<br> 6 cm

Mariulka [41]

Answer:

The <em>surface area</em> of the cube is equal to 216 cm².

General Formulas and Concepts:
<u>Geometry</u>

Surface Area Formula [Cube]:
$\displaystyle \text{SA} = 6a^2$

<em>a</em> is a side length

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify given variables</em>.

<em>a</em> = 6 cm

<u>Step 2: Find Surface Area</u>

[Surface Area Formula - Cube] Substitute in <em>a</em>:
$\displaystyle \text{SA} = 6(6 \ \text{cm})^2$
Evaluate:
$\displaystyle \text{SA} = \boxed{216 \ \text{cm}^2}$

∴ we have found the surface area of the cube to be 216 cm².

A) y=5/x what happens to the value of y if the value of x triples

Troyanec [42]

Answer:

Y is going to triple(y1=3y)

Step-by-step explanation:

y=5/x;

x triples means y1=5/(3x);

Y1 divided by y, we get (5/x)/(5/3x)=(5/x)*(3x/5)=3

David Barnes and his fiancée Valerie Shah are visiting Hawaii. At the Hawaiian Cultural Center in Honolulu, they are told that

balandron [24]

Using the hypergeometric distribution, it is found that there is a 0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.

The people are chosen without replacement from the sample, hence the <em>hypergeometric distribution </em>is used to solve this question.

<h3>What is the hypergeometric distribution formula?</h3>

The formula is:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

In this problem:

There is a total of 18 people, hence $N = 18$ .

2 people will be chosen, hence $n = 2$ .

David and Valerie corresponds to 2 people, hence $k = 2$ .

The probability that both get picked is P(X = 2), hence:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$P(X = 2) = h(2,18,2,2) = \frac{C_{2,2}C_{16,0}}{C_{18,2}} = 0.0065$

0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.

Coach leonardo used 9 1/2 meters of string to mark a soccer field for a game. He also used 2 2/5 meters of string to mark a spot

allsm [11]

Answer:

10 19/10 meters

Step-by-step explanation:

Step one:

given data

let the amount of string used for the soccer field be x

and the amount used for coach spot be y

Also, let the total string used be represented as T

Step two:

Hence the expression for the total is

T= x+y

T= 9 1/2+ 2 2/5

T= 9.5+ 2.4

T= 11.9

or

T= 119/10 meters

or

T= 10 19/10 meters
