Marina CMI [18]

Answer:

The option <u> J 36.7 inches</u>  best represents the length of hypotenuse.

Step-by-step explanation:

<u><em>The question is incomplete, so below is the complete question:</em></u>

A triangle has one leg of 32 inches and one leg of 18 inches. For the triangle to be a right triangle, which best represents the length of the hypotenuse?

F 34.2 inches  G 36 inches  H 41.8 inches  J 36.7 inches.

Now, to find the hypotenuse.

Leg 1 = 32 inches.

Leg 2 = 18 inches.

Now, to get the hypotenuse we use pythagoras theorem:

(Leg1)^2+(Leg2)^2=(Hypotenuse)^2

(32)^2+(18)^2=(Hypotenuse)^2

1024+324=(Hypotenuse)^2

1348=(Hypotenuse)^2

Using square root on both sides we get:

36.7=Hypotenuse

Hypotenuse=36.7\ inches.

Therefore, the option J 36.7 inches best represents the length of hypotenuse.

Find the surface area of the sphere with the given dimension. Leave your answer in terms of pi.
Brrunno [24]
The surface area of the sphere:
A = 4 r² π 
1 ) r = 60 m;
A = 4 · 60² π = 4 · 3600 π = 14,400 π m²
2 ) Diameter of 14 cm:
r = 14 cm / 2 = 7 cm
A = 4 · 7² π = 4 · 49 π = 196 π cm²

A rectangles width is one fifth it's length and it's perimeter is 168m. Find the dimensions of the rectangle
gayaneshka [121]
I hope this helps you



width = 1/5 .length


length =5.width


Perimeter =2 (w+l)


168=2. (w+5w)


84=6w


w=14


l=5.14=70

Point A is located at (2, 3) on the coordinate plane. Point A is reflected over the x-axis to form point B and over the y-axis t
Mademuasel [1]

Answer:

Rectangle

Step-by-step explanation:

Well if point A is on (2,3) and you reflect it over the x axis point B would be located at (2,-3).

Then over the y axis point C would be located at (-2,-3), then reflecting that over the x axis point D is (-2,3)

<em><u>Points</u></em>

__________

A. (2,3)

B. (2,-3)

C. (-2,-3)

D. (-2,3)

__________

So graphing all these points we get a rectangle.

Because it has 4 sides that are 90 degrees and the sides opposite from each other are the same.

The molar mass of AlCl3 is 133.34 g/mol. How many molecules of AlCl3 are there in 2 g?
Mnenie [13.5K]

To solve this problem, we have to apply mole-concept to this and we would need the molar mass of AlCl3.  2g of AlCl3 contains 9.034*10^21 molecules.

<h3>Number of Molecules in 2g of AlCl3</h3>

The molar mass of AlCl3 is given as 133.34g/mol

Data;

  • mass = 2g
  • molar mass = 133.34g/mol

Using the mole concept, we can equate the molar mass to the number of molecules present in the entity.

133.34g = 6.023*10^2^3

If we equate this

133.34g = 6.023*10^2^3\\2g = x molecules\\x = \frac{2*6.023*10^2^3}{133.34} \\x = 9.034*10^2^1 molecules

From the calculations above, 2g of AlCl3 contains 9.034*10^21 molecules.
