Answer 1

Answer:

Tn = 8n - 2

Step-by-step explanation:

Given the arithmetic sequence

6, 14, 22, 30, 38

The nth term is expressed as;

Tn = a +(n-1)d

a is the first term = 6

d is the common difference = 14 - 6 = 22 - 14 = 8

Substitute into the formula;

Tn = 6 + (n-1)(8)

Tn = 6 + 8n-8

Tn = 8n - 2

Hence the nth term of the sequence is 8n-2

Piper opened a savings account with $1400 that pays no interest. She deposits an
additional $50 each week thereafter. How much money would Piper have in the
account 47 weeks after opening the account?

Answers

Answer:  Piper will have $3750  

Step-by-step explanation:

In this situation we will represent the total amount she have in the bank by y and the number of weeks by x

The whole situation can be represented by the the equation

  y = 1400 + 50x  where y is the total amount , 1400 is the initial amount Piper deposited , 50 is of course the amount Piper will deposit each week , and x is the number of weeks.

Now since they are looking for the amount Piper will have in his account, you have to input 47 for x and solve for y.

y = 1400 + 50(47)

y = 1400 + 2350

y = 3750

On the playground, 1/4 of the students are on the jungle gym, and 1/3 f the students are playing kickball. What part of all the students on the playground is on the jungle gym or playing kickball?

Answers

Answer:

7/12 of the students

Step-by-step explanation:

So first you would need to get your fractions to have the same denominator. When your trying to get your fractions to get the same denominato. You must multiply both the numerator and denominator.

The most common denominator from 1/4 and 1/3 is 12. So you multiply both the numerator and denominator of 1/4 by 3. So then your new fraction is 3/12. Now you multiply 1/3, both numerator and your denominator by 4. Then your new fraction is 4/12. So The last step is to add both of your numerators. Never add the denominators together. And at last you have your answer. 7/12.

Convert the following equation to Slope-Intercept Form
HINT: Slope-Intercept Form is y = mx + b
y-8= 3(x + 5)

Answers

Answer:

y = 3x + 23

Step-by-step explanation:

Given the equation :

y - 8 = 3(x + 5)

We are to convert the equation to slope - intercept form:

Recall: general form of a slope - intercept model:

y = mx + c

Hence,

y - 8 = 3x + 15

y = 3x + 15 + 8

y = 3x + 23

Comparing :

y = mx + c

y = 3x + 23

Water along the Mississippi River is rising at a rate of 24.8 cm/hr. The top of a dock in the river currently sits only 1.2 meters above the water. How many hours will it take the water to reach the top of the dock

Answers

Answer:

4.84*10^-4hours

Step-by-step explanation:

Speed = Distance/Time

Time = Distance/Speed

Given

Distance = 1.2m = 0.012cm

Speed = 24.8cm/hr

Get the time;

Time = 0.012/24.8

Time = 4.84*10^-4hours

Hence it will take the water 4.84*10^-4hours to reach the top of the dock

So far, Phillip has completed 3/4 of his run. If he has run 9 miles, how far does he plan to run

Answers

Answer:

He has to run a total of 12 miles and has 3 more miles to run

Step-by-step explanation:

Well we know that 3/4 is 9 out of the total miles he is willing to run. We can divide 9 by 3 to get 1

Now we know 1/4 of his run is 3 miles

3*4= 12

He has to run a total of 12 miles and has 3 more miles to run

Answer:

He plans to run 12 miles

Step-by-step explanation:

He plans to run 12 miles because if he ran 9 miles so far and that is 3/4 of his way then you would do 3 divided by 9 to get 3.  Then you would add a 3 to nine because that 3 would be the last quarter t complete his run.

What’s the answer to m/3-2m/5=1/5

Answers

Answer:

m = - 3

Step-by-step explanation:

[tex]\frac{m}{3} - \frac{2m}{5} = \frac{1}{5}[/tex]

It is much easier to work with whole numbers, compared to fractions, hence one should remove the denominator of the fraction. This can be done by multiplying by the LCM (least common multiple). In this case, it is fairly obvious that the LCM of 3 and 5 is 15. Therefore multiply the entire equation by 15.

[tex]15*\frac{m}{3} - 15*\frac{2m}{5}=15*\frac{1}{5}[/tex]

Simplify

[tex]5m-6m=3[/tex]

[tex]-m=3\\m=-3[/tex]
