The first one can be done by Pythagoras theorem such as $12^2=9^2+x^2$ then $x^2=63$ then $x= \sqrt{63}$

The second one can also done by Pythagoras theorem, note that this is isosceles triangle so $y=z$ , again by using Pythagoras theorem $15^2=y^2+z^2=y^2+y^2 or =z^2+z^2$ then $225=2y^2$ then $y= \sqrt{\frac{225}{2} }$

For the last one can also done by property of 30-60-90 triangle. $w=8 \sqrt{3}$ $k=2.8=16$

Write the phrase "the product of 19 and a number" as a mathematical expression.

Sedbober [7]

Answer:

Phrase : "the product of 19 and a number"

Mathematical expression : 19A

Step-by-step explanation:

Phrase : "the product of 19 and a number"

The product of two numbers a and b can be written as a x b =ab

<u>To find Mathematical expression </u>

Let A be a number,

The product of number with 19 can be written as

19 x A = 19A

Therefore the given phrase "the product of 19 and a number" as a mathematical expression =19A

An art exhibit is made by stacking three identical prisms on top of each other end-to-end so their smallest faces overlap. One o

cestrela7 [59]

The surface area of the exhibit is 1,638 cubic inches.

Step-by-step explanation:

Step 1:

If three prisms are out on top of each other we get a shape as follows;

The length of the base $= 9$ inches,

The width of the base $=6$ inches, and

The height of the exhibit $= 3(17) = 51$ inches.

To find the surface area of the total exhibit we consider there to be only one shape which the above dimension.

Step 2:

There are 6 faces to the exhibit.

The surface area of a rectangular prism is given by;

$A=2(w l+h l+h w)$

By substituting the values, we get

$A=2((6)(9)+(51) (9)+(51) (6)) = 2 (819) = 1,638.$

The surface area of the exhibit is 1,638 cubic inches.

(adapted from Ross, 2.31) Three countries (the Land of Fire, the Land of Wind, and the Land of Earth) each make a 3 person team.

DaniilM [7]

Answer:

The answer is " $\frac{2}{9} \ and \ \frac{1}{9}$ "

Step-by-step explanation:

In point a:

The requires 1 genin, 1 chunin , and 1 jonin to shape a complete team but we all recognize that each nation's team is comprised of 1 genin, 1 chunin, and 1 jonin.

They can now pick 1 genin from a certain matter of national with the value:

$\frac{1}{\binom{3}{1}}=\frac{1}{3} .$

They can pick 1 Chunin form of the matter of national with the value:

$\frac{1}{\binom{3}{1}}=\frac{1}{3} .$

They have the option to pick 1 join from of the country team with such a probability: $\frac{1}{\binom{3}{1}}=\frac{1}{3}$

And we can make the country teams: $3! = 6$ different forms. Its chances of choosing a team full in the process described also are:

$6 \times \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}=\frac{2}{9}.$

In point b:

In this scenario, one of the 3 professional sides can either choose 3 genins or 3 chunines or 3 joniners. So, that we can form three groups that contain the same ninjas (either 3 genin or 3 chunin or 3 jonin).

Its likelihood that even a specific nation team ninja would be chosen is now: $\frac{1}{\binom{3}{1}}=\frac{1}{3}$

Its odds of choosing the same rank ninja in such a different country team are: $\frac{1}{\binom{3}{1}}=\frac{1}{3}$

The likelihood of choosing the same level Ninja from the residual matter of national is: $\frac{1}{\binom{3}{1}}=\frac{1}{3}$ Therefore, all 3 selected ninjas are likely the same grade: $3\times \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}=\frac{1}{9}$
