A system of identifying call letters uses call letters that begin either with E or W. Some have a total of 2 letters, and others

Klio2033 [76]

Answer:

If repetition is allowed then the different call letters possible are 1404.

If repetition is allowed then the different call letters possible are 1250.

Step-by-step explanation:

The call letter are of either 2 letter or 3 letters.

And for them to be identified they should start with either E or W.

If Repetition is allowed:

Consider the call letters with 2 letter:

Possible number of call letters starting with E : E _

The second place can be filled any of the 26 letters.

Possible number of call letters starting with W : W _

The second place can be filled any of the 26 letters.

Consider the call letters with 3 letter:

Possible number of call letters starting with E : E _ _

The second place and third place can be filled with any of the 26 letters.

Possible number of call letters starting with W : W _ _

The second place and third place can be filled with any of the 26 letters.

Total number of possible letters: 26 + 26 + (26)² + (26)² = 1404

Thus, if repetition is allowed then the different call letters possible are 1404.

If Repetition is not allowed:

Consider the call letters with 2 letter:

Possible number of call letters starting with E : E _

The second place can be filled any of the 25 letters.

Possible number of call letters starting with W : W _

The second place can be filled any of the 25 letters.

Consider the call letters with 3 letter:

Possible number of call letters starting with E : E _ _

The second place can be filled with any of the remaining 25 letters and the third can be filled with the remaining 24 letters.

Possible number of call letters starting with W : W _ _

The second place can be filled with any of the remaining 25 letters and the third can be filled with the remaining 24 letters.

Total number of possible letters: 25 + 25+ (25 × 24) + (26 × 24) = 1250

Thus, if repetition is allowed then the different call letters possible are 1250.

A local water storage facility is currently empty. The city

Semenov [28]

Answer: See explanation

Step-by-step explanation:

a) How much-water will be in the water storage facility in 25 minutes?

Since the city water workers begin filling it at a rate of 500 gallons per minute, in 25 minutes they'll have filled:

= 500 × 25

= 12500 gallons

It immediately begins sending some of its water into the city's water pipes at a rate of 150 gallons per minutes. In 25 minutes, they'll have sent:

= 150 × 25

= 3750 gallons

Amount that'll be left in the tank will be:

= 12500 - 3750

= 8750 gallons

b. Write an equation to find the number of gallons,y,in the storage facility after x minutes. This will be:

y = (500 × x ) - (150 × x)

y = 500x - 150x

y = 350x

A new car is purchased for 23900 dollars. The value of the car depreciates at 14.25% per year. To the nearest tenth of a year, h

svp [43]

Answer:

The value of the car will be 6100 dollars in 8.8 years

Step-by-step explanation:

Present value of car = $23900

The value of the car depreciates at 14.25% per year

Let x be no. of years in which the value of the car becomes 6100 dollars

Formula: $N(t)=N_0(1-r)^t$

Substitute the values :

$6100=23900(1-\frac{14.25}{100})^x\\\frac{6100}{23900}=(1-\frac{14.25}{100})^x\\x=8.8$

Hence the value of the car will be 6100 dollars in 8.8 years

In a sixth grade class, the ratio of boys to girls is 4:3 if there are 35 students in the class how many girl are there

babunello [35]

Step-by-step explanation:

The ratio is 4:3

First you would do 4 + 3 which is 7

Then you would do 35 ÷ 7 which is 5

Finally we would multiply 5 to the ratio 4:3

So 7 × 4 is 28

And 7 × 3 is 21

So the new ratio is 28:21

So there are 21 girls in the class

Hope this makes sense
