A conservative estimate of the number of stars in the universe is 6 x 10^22. The average human can see about 3,000 stars at nigh

Ilia_Sergeevich [38]

$2 \times 10^{19}$ times more stars are there in universe compared to human eye can see

<h3><u>Solution:</u></h3>

Given that, conservative estimate of the number of stars in the universe is $6 \times 10^{22}$

The average human can see about 3,000 stars at night with only their eyes

To find: Number of times more stars are there in the universe, compared to the stars a human can see

Let "x" be the number of times more stars are there in the universe, compared to the stars a human can see

Then from given statement,

$\text{Stars in universe} = x \times \text{ number of stars human can see}$

<em><u>Substituting given values we get,</u></em>

$6 \times 10^{22} = x \times 3000\\\\x = \frac{6 \times 10^{22}}{3000}\\\\x = \frac{6 \times 10^{22}}{3 \times 10^3}\\\\x = 2 \times 10^{22-3}\\\\x = 2 \times 10^{19}$

Thus $2 \times 10^{19}$ times more stars are there in universe compared to human eye can see

Use the diagram to answer the following questions

n200080 [17]

Answer:

a. line AR, line AV

b. plane TSR, plane QTZ, plane RSZ

c. A, R, V

d. Q, R, S, T

e. QR

f. RQ, RS

Step-by-step explanation:

a. In addition to a name given to a line ("line p"), a line can be named by any two points on that line. Here, possible names are ...

line AR, line RA, line AV, line VA, line RV, line VR

any two of these names will appropriately answer this part of the question.

__

b. In addition to a name given to a plane ("plane W"), a plane can be named by any three points in that plane. Here, there are 5 named points in the plane (3 of which are collinear), so there are 54 possible different names for the plane. Some of them are ...

plane RST, plane TSR, plane QTZ, plane RSZ

__

c. In this diagram, each of the lines shown has three named points on it. Possible answers to this part of the question are ...

{Q, R, S} or {A, R, V}

__

d. Any four of the 5 named points shown in plane W will serve to answer this question. Possible answers are ...

{R, S, T, Z} or {Q, S, T, Z} or {Q, R, T, Z} or {Q, R, S, Z} or {Q, R, S, T}

__

e. Any pair of collinear points will name a line segment. Here, there are 12 possible names for line segments, including ...

QR, RQ, QS, SQ, RS, SR, AR, RA, ...

__

f. Opposite rays can be named by choosing the end point as the middle of three collinear points. Here, the only such middle point is R. We can name pairs of opposite rays on either line. The endpoint of the ray is named first.

{RA, RV} or {RQ, RS}

Paul wrote the equation t=2m+40 to represent the temperature, t, in degrees Celsius, after a substance had been heated for m min

Usimov [2.4K]

First you need to fill in the variables with what you already know, so
t=2m+40.
You don’t have enough information to solve this problem. You need to have only 1 variable to solve it or you need more information

What are uniform motion problems

zhuklara [117]

Distance-Rate-Time Problems. An object that moves at a constant rate is said to be in uniform motion. ... Uniform motion problems may involve objects going the same direction, opposite directions, or round trips. In the diagram below, the two vehicles are traveling the same direction at different rates.
