Answer:

Step-by-step explanation:

To compute a log that doesn't have a base of 10 you use the following formula

Log(number)/Log(base)

We can use this formula to compute the numbers with no variables

Log₃18= Log(18)/log(3) which gives us around 2.63

We can then compute the first part of the right side 2*log₃6 which can be rewritten as 2*(log(6)/log(3)) which gets us around 3.26

After computing this we can rewrite it all as 2.63=3.26-(.5*log₃x)

This is pretty easy to solve from here and we start by subtracting 3.26 from both sides which gives up

-.63=.5*log₃x

Dividing both sides by negative one half (or .5) gives us

1.26=log₃x

You then can use a special rule to rewrite this equation

3^1.26=x

This gives us 3.99 which is pretty much 4

In RSM camp, there are four counselors for every fifty seven students and three teachers for every five counselors. Chapter Refe

max2010maxim [7]

The number of students attending the camp that summer is 380 students

Step-by-step explanation:

There are four counselors for every fifty seven students

There are three teachers for every five counselors

Ms. Rifkin asked all 16 teachers present at the camp to attend a

teachers meeting

To solve this question we will use the ratio

The given is:

1. 4 counselors for every 57 students

2. 3 teachers for every 5 counselors

3. There are 16 teachers

At first let us find the 16 teachers are for how many counselors

∵ 3 teachers : 5 counselors

∵ 16 teachers : x counselors

∴ $\frac{3}{5}=\frac{16}{x}$

By using cross multiplication

∴ 3x = 16 × 5

∴ 3x = 80

Divide both side by 3

∴ x = $\frac{80}{3}$

Then let us find the $\frac{80}{3}$ counselors are for how many students

∵ 4 counselors : 57 students

∵ $\frac{80}{3}$ counselors : y students

∴ $\frac{4}{57}=\frac{80/3}{y}$

By using cross multiplication

∴ 4y = 57 × $\frac{80}{3}$

∴ 4y = 1520

Divide both sides by 4

∴ y = 380 students

The number of students attending the camp that summer is 380 students

Plz help(by solving for x)

Alex Ar [27]

Answer:

x = 5.85641

Step-by-step explanation:

Step 1: Find missing leg of left triangle

sin30° = x/16

16sin30° = x

x = 8

Step 2: Find missing leg of right triangle

8² + b² = 16²

b² = 192

b = 8√3

Step 3: Find <em>x</em> by taking the difference

8√3 - 8 = 5.85641

The probability that it will snow on the last day of January is 85%. If the probability remains the same of the first eight day

MrRa [10]

Answer:

Here, we have:

P(5 days snow in this 8 days) = 8C5 x (0.85)^5 x (1 - 0.85)^3 = 0.084

P(6 days snow in this 8 days) = 8C6 x (0.85)^6 x (1 - 0.85)^2 = 0.238

P(7 days snow in this 8 days) = 8C7 x (0.85)^7 x (1 - 0.85)^1 = 0.385

P(8 days snow in this 8 days) = 8C8 x (0.85)^8 x (1 - 0.85)^0 = 0.272

Add up those above, then the probability that it will snow AT LEAST five of those days in February:

P = 0.084+ 0.238 + 0. 385 + 0.272 = 0.979

Hope this helps!
