Answer:

x = 5/3

General Formulas and Concepts:
Algebra I

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtraction Property of Equality

Step-by-step explanation:

Step 1: Define

Identify given.

y = 3x - 2

y = 3

Step 2: Solve for x

[Equation] Substitute in y:
3 = 3x - 2
[Addition Property of Equality] Add 2 on both sides:
5 = 3x
[Division Property of Equality] Divide 3 on both sides:
5/3 = x
Rewrite:
x = 5/3

∴ the value of x when y = 3 is equal to 5/3, or approximately 1.67.

Calculate the noon sun angles for new orleans, usa and helsinki, finland on september 22. in the answer below, new orleans answe

Otrada [13]

We need to calculate noon sun angle. Noon sun angle is an angle at which sun-rays fall at noon on a given date.
On September 22, the sun’s rays form a 90° angle at noon at the equator.

Formula for calculating noon sun angle is:

Noon_sun_angle = 90° - Zenith angle

We have complementary angles so we need to substract zenith angle from 90°.

The zenith angle is the distance between subsolar point (point where sun is at 90°) and the latitude of an observer. In our case this angle will have same value as latitude because subsolar point is at equator 0°. If our latitude and subsolar point are at same hemisphere we substract values. Otherwise we add values.

New Orleans, USA
Latitude = 30°
Noon_sun_angle = 90° - 30° = 60°

Helsinki, Finland
Latitude = 60°
Noon_sun_angle = 90° - 60° = 30°

RideAnS [48]

Answer:

The candle must burn at 2cm per hour in order to be 6cm tall after 4 hours. I know this because the candle has to burn 8cm in 4 hours and that amounts to 2cm per hour.

Step-by-step explanation:

Lets solve!

We have to find out how much of the candle needs to be burned!

14cm - 6cm = 8cm

The candle must burn 8cm in 4 hours!

Lets find out how much the candle burns in 1 hour.

$\frac{8cm}{4hours}$ = 2cm per hour

The candle must burn at 2cm per hour in order to be 6cm tall after 4 hours. I know this because the candle has to burn 8cm in 4 hours and that amounts to 2cm per hour.

Woohoo, We did it! Would you like to mark my answer as brainliest? I would love that!

Calculate the mean of each data set below. Can you find any shortcuts that allow you to find the mean without having to do much calculation? Homework help 6, 10, 6, 10 11, 12, 12, 13, 12 0, 5, 4, 8, 0, 7

Answer: To find the mean of the given observations. we just need to first find the sum of the given observations and the divide the calculate sum by the total number of observations.

So here:

Sum of of observations $=6+ 10+ 6+10+11+12+12+13+12+0+ 5+ 4+ 8+ 0+7=116$
