Using proportions, it is found that both spaces have the same brightness, as both have 3 candles per m².

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

For Nayeli and Citlali, the rate of candles per m² is given by:

  • N = 12/4 = 3 candles per m².
  • C = 30/10 = 3 candles per m².

Hence both spaces have the same brightness, as both have 3 candles per m².

The length of a side of a triangle is 36. A line parallel to that side divides the triangle into two parts of equal area. Find t
Hitman42 [59]

Answer:

Length of BE is \frac{36}{\sqrt2}units

Step-by-step explanation:

The length of a side of a triangle is 36. A line parallel to that side divides the triangle into two parts of equal area. we have to find the length of the segment determined by the points of intersection between the line and the other two sides of the triangle.

Now, the two parts of triangle have equal area ∴ ar(ADE)=ar(BDEC)

⇒ ar(ADE)=\frac{1}{2}ar(ABC)

⇒ \frac{ar(ADE)}{ar(ABC)}=\frac{1}{2}

In ΔABE and ΔABC,

∠A=∠A     (Common)

∠ABE=∠ABC   (Corresponding angles)

By AA similarity, ΔABE is similar to ΔABC.

Hence by area side proportionality theorem

\frac{ar(ADE)}{ar(ABC)}=(\frac{BE}{BC})^2

⇒ \frac{1}{2}=\frac{BE^2}{36^2}

⇒ BE^2=\frac{36^2}{2}

⇒ BE=\frac{36}{\sqrt2}units

Hence, length of BE is \frac{36}{\sqrt2}units

Solving systems of linear inequalities ​
Liono4ka [1.6K]

Answer:

To solve a system of of linear inequalities, you could do the elimination method or substitution method.

Step-by-step explanation:

  • For elimination method, you can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

For substitution method, you have to:

Step 1 : First, solve one linear equation for y in terms of x.

Step 2 : Then substitute that expression for y in the other linear equation.

Step 3 : Solve this, and you have the x -coordinate of the intersection.

Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.

Find the value of x don’t understand how to do this
RUDIKE [14]

Answer:

x=56

Step-by-step explanation:

I may be wrong but

That’s a pentagon so

5-2=3

180x3=540 ( total area of a pentagon)

89+99+72= 260

540-260=280

3+2=5

280/5=56

x=56

HELP MEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!!!!!!
Luda [366]

Answer:

A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
