Answer: x = 10

Step-by-step explanation:ln20+ln5=2lnx

ln(20x5)=lnx^2

ln100=1nx^2

100=x^2

square root

x=10

Answer:

x = 10

Step-by-step explanation:

l n 20 + l n 5 = 2 l n x

ln (20×5) = ln x²

ln(100) = lnx²

100 = x²

x = +/- 10

Since logs of negative numebrs don't exist, we reject -10

The rule T1, -4 RO, 180°(x, y) is applied to rectangle KLMN. Which rectangle shows the final image??

fomenos

Let me help you!

Looking at the visual, we can see five figures: KLM, 1, 2, 3, and 4.
Applying the rule T1, -4 RO, 180°(x, y) to rectangle KLMN - without even solving - just by merely observing, we can say (without a doubt) that the rectangle KLMN will most likely fall in the negative axis.

First rotation: -4 to the left.
Second rotation: -4 to the left.
Last rotation: -4 to the left making the last figure 3. <----- What we are looking for!

Therefore, the rectangle which shows the final image is figure 3 or rectangle 3.

Answer:

Area = 8.60 × 10² mm³

Step-by-step explanation:

Finding the Width first:

Width = 4(r) [Because 4 radius-es make up the width]

Width = 4(24 mm)

Width = 96 mm

Now, The length:

Length = $r(2+\sqrt{3} )$ [Because Length is made up of 2 radius-es and an √3 radius also!]

Length = (24)(2+1.7)

Length = (24)(3.7)

Length = 89.6 mm

Now, The Area:

=> Area of Rectangle = $Length*Width$

=> Area = 96 * 89.6

=> Area = 8.60 × 10³ mm² [Correct up to 3 significant figures]

If 20% of the people in a small town are voters, and there are 2,360 voters, what is the population of the town?

Gemiola [76]

Hi.

20% is 1/5 of the population. To find out 100% of the population, we can multiply by 5.

2,360 • 5 = 11,800

The population of the town is 11,800.

Cheers~
