NEED HELP ASAP !!!!!!!!
Papessa [141]

Answer: Stephon can buy total 4 chips bag and 2 candy bar

Step-by-step explanation:Given as :

The money which Stephon has in his pocket = $ 12

The cost of one chips bag = $ 2.25

The cost of one candy bar = $ 1.50

The total number of items he can buy = 6

So, Let the number of chips bag he can buy = x

∴ The number of candy bar he can buy = 6 - x

Now, according to question

The number of chips bag×The cost of one chips bag + The number of candy bar×The cost of one candy bar = $ 12

Or, x × $ 2.25 + (6-x) × $ 1.50 = $ 12

Or,  x × $ 2.25 + 9 -  x × $ 1.50 = $ 12

or,  x × $ 0.75 = 12 - 9

or, x =  = 4

The number of chips bag he can buy = x = 4

And The number of candy bar he can buy = 6 - x = 6 - 4 = 2

Hence Stephon can buy total 4 chips bag and 2 candy bar .

Write the first three terms in the following sequences. Identify them as arithmetic or geometric
vaieri [72.5K]

Answer:

A(1)=9

A(2)=4

A(3)=-1

Arithmetic sequence

Step-by-step explanation:

We are given that

A(n+1)=A(n)-5 \;for\;n\geq 1 A(1)=9

We have to find first three terms and identify the sequence is geometric or arithmetic.

Substitute n=1

Then, we get

A(2)=A(1)-5=9-5=4

For n=2

A(3)=A(2)-5=4-5=-1

For n=3

A(4)=-1-5=-6

d_1=A_2-A_1=4-9=-5

d_2=A_3-A_2=-1-4=-5

d_3=A_4-A_3=-6+1=-5

d_1=d_2=d_3=-5

When the difference of consecutive terms are constant then the sequence is arithmetic sequence.

Therefore, given sequence is arithmetic sequence.

Hello! Anyone able to help me with question 3 + explanation too? Thanks!
taurus [48]

Answer:

2 or 12

Step-by-step explanation:

The answer that we will use this equation 1/t1 +1/t2=1/ttotal

where t1 is the time of smaller pipe while t2 is the of the larger pipe

Given t total =4 while t2 is equal to t2=t1-6

So know you can solve the problem by changing it into (2t1-6)/(t1*(t1-6))=1/4

8( t1-3)=(t1^2-6t1)

t1^2-14t1+24=0

t1=2 or 12
