Answer:

The answer is,

r =  \frac{3t}{t - 1}

Step-by-step explanation:

t =  \frac{r}{ r - 3}

Firstly, you have to get rid of fraction by multiplying (r-3) to both side and expand out:

t × (r-3) = r/(r-3) × (r-3)

rt - 3t = r

Then you have to move all the "r" variables to one side and other variables to the other side:

rt - r = 3t

You can make "r" as a subject by taking out the common term, you can see that the common term on the left is "r" so you can bring out:

r(t-1) = 3t

r = 3t/(t-1)

One of the students wanted to know the material in the four propeller
Lyrx [107]

The material is made of carbon composite since the density of this material is similar to the drone

<h3>What is density?</h3>

Density is mass per unit volume. It is is an important property of a material that helps in saying other features of the material. It also says substance that has more weight as a highly dense substance will have more weight when compared with a less dense substance.

<u>Given data</u>

Initial volume of water = 1000ml

the drone displaced the water to 2290 ml

mass of the drone = 2 kg = 2000 g

<h3>Density of the drone</h3>

volume of the drone equals the volume of water displaced

2290 ml - 1000 ml = 1290 ml

density in g/cm*3

= mass / volume

= 2000 / 1290

= 1.550 g/ml

The density of the drone is similar to density of carbon composite hence the drone of made of carbon composite

Solve each equation by completing the square <br> 6) m² + 16m – 8 = 0
Natali5045456 [20]

Answer:

m = - 8 ± 6\sqrt{2}

Step-by-step explanation:

Given

m² + 16m - 8 = 0 ( add 8 to both sides )

m² + 16m = 8

To complete the square

add ( half the coefficient of the m- term )² to both sides

m² + 2(8)m + 64 = 8 + 64

(m + 8)² = 72 ( take the square root of both sides )

m + 8 = ± \sqrt{72} = ± \sqrt{36(2)} = ± 6\sqrt{2}

Subtract 8 from both sides

m = - 8 ± 6\sqrt{2}

Complete the table. Will choose brainliest.
maxonik [38]

Answer:

first one is 82% second is 214%

Step-by-step explanation:

Step 1: Divide 288 by 351 to get the number as a decimal. 288 / 351 = 0.82

Step 2: Multiply 0.82 by 100. 0.82 times 100 = 82

Step 1: Divide 212 by 99 to get the number as a decimal. 212 / 99 = 2.14

Step 2: Multiply 2.14 by 100. 2.14 times 100 = 214
