How to find the length of a leg of a 45 45 90 triangle?

1 answer:

6 0

The legs are the same length. if x represent the legs length the hypotenuse is equal to x√2. if you have the length of the hypotenuse just divide its length by the square rot of two.

According to the 2008 U.S. census, California had a population of approximately 4 × 10^7 people and Florida had a population of

qaws [65]

Answer:

D. The population of California was approximately two times the population of Florida.

Step-by-step explanation:

California's population was 4 x 10^7= 40,000,000

Florida's population was 2 x 10^7= 20,000,000

So therefore Califirnia's population was approximately two times the population of Florida.

I hope this helps!!

A triangular pyramid has the same base and height as a triangular prism. The volume of the prism is 66 cubic inches. What is the

notka56 [123]

The volume of the triangular prism is 66 cubic inches.
In order for us to know the volume of the triangular pyramid, first we need to know the ratio of the volume of triangular prism and the volume of the triangular pyramid.

Volume of the pyramid = 1/3 * volume of the prism.
Volume of the pyramid = 1 / 3 * 66
<span>Volume of the pyramid = 22 cubic inches.
</span>
So the volume of the triangular pyramid is 22 cubic inches.

Part 1. Determine the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm. Show your work.

sdas [7]

If a sample of gas is a 0.622-gram, volume of 2.4 L at 287 K and 0.850 atm. Then the molar mass of the gas is 7.18.

<h3>What is an ideal gas equation?</h3>

The ideal gas equation is given below.

$PV = nRT$

The equation can be written as

$\rm PV = \dfrac{m}{M} \ RT\\\\\\MPV = mRT$

Where M is the molar mass, P is the pressure, V is the volume, R is the universal gas constant, T is the temperature, and m is the mass of the gas.

Then the molar mass of a 0.622-gram sample of gas has a volume of 2.4 L at 287 K and 0.850 atm.

V = 2.4 L = 0.0024

P = 0.85 atm = 86126.25 Pa

T = 287 K

m = 0.622

R = 8.314

Then we have

$\begin{aligned} \rm M \times 86126.25 \times 0.0024&= 0.622 \times 8.314 \times 287\\\\\rm M &= 7.18 \end{aligned}$
