Multiply 2 with eq. (1) and 4 with eq. (2)

8x + 4y = 20 ____________(3)

8x + 12y = 132 ______(4)

Subtracting (3) from (4),

A company rents out 14 food booths and 26 game booths at the county fair. The fee for a food booth is $175 plus $8 per day. The fee for a game booth is $65 plus $7 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.

The expression is ________

Answers

Answer:

$4140 + $294d

Step-by-step explanation:

Hello,

Let's write down what we know first,

d days

14 food baths -- $175 and $8 per day

26 game booths -- $65 and $7 per day

What we want to find the amount of money paid for both food baths and game booths so after finding them individually, we need to add them up.

We already know the company rents out 14 fb and 26 gb and we know that each fb is 175 dollars and each gb is 65 dollars, so we should find out the cost of buying them. We can also write out the total cost of

14 * $175 = $2450

26 * $65 =  $1690

Now lets find the per day cost,

14 * $8 * d = $112d

26 * $7 * d = $182d

With both equations added together we get,

$2450 + $112d

$1690 + $182d

Add those together and we get:

$4140 + $294d

The height of a male athlete testing his vertical jump can be modeled by h = − 16t ^2 + 14t. The height is h and the time is t. How many seconds is he in the air?

Answers

Answer:

0.88 (I think this is how Mrs. Futch wants it to be written)

Step-by-step explanation:

h=-16t^2+14t

(Substitute h with 0)

0=-16t^2+14t

(Factor)

0=2t(-8t+7)

2t=0               -8t+7=0

Adrian invested $790 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $2,550?​

Answers

Answer:17

Step-by-step explanation:

trust me its right, no cap

As per compound interest,  it would take 17 years for the value of the account to reach $2,550

What is the compound interest?

If the invested amount is 'P', the rate of interest is r%, and the time of investment is 'n' years, then the compound interest after mentioned duration is = P[1 -  [tex]e^{rn}[/tex]]

Given, the invested amount (P) = $790.

Rate of interest (r) = 6.9% = 0.069.

Let, the amount is invested for 'n' years.

The value of the amount after 'n' years = $2550.

Now, as per compound interest:

A = P. [tex]e^{rn}[/tex]

⇒ 2550 = 790 [tex]e^{(0.069n)}[/tex]

⇒ [tex]e^{(0.069n)}[/tex] = (2550 ÷ 790)

⇒ [tex]e^{(0.069n)}[/tex] = 3.23

⇒ 0.069n = 1.172

⇒ n = 17

An online furniture store sells chairs for $150 each and tables for $400 each. The store must sell a minimum of $4900 worth of chairs and tables each day. Write an inequality that could represent the possible values for the number of tables sold, tt, and the number of chairs sold, cc, that would satisfy the constraint.

Answers

Answer: 150c + 400t ≥ 4900

Step-by-step explanation:

Let the number of chairs sold = c

Let the number of tables sold = t

Price for each chair = $150

Price for each table = $400

The inequality that could represent the number of tables and chairs sold will be:

(150 × c) + (400 × t) ≥ 4900

150c + 400t ≥ 4900

Which answer describes the sequence {1,3,7,15,…} as a mathematical statement?

Answers

Answer:

so just successive powers of 2

Step-by-step explanation:

1, 3, 7, 15, 31, 63, _? Add successive powers of 2 to the number: 1+2=3; 3+4=7; 7+8=15; 15+16=31; 31+32=63; 63+64=127.

The given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.

Given that,

To justify the given sequences 1,3,7,15.


What is arithmetic progression?

Arithmetic progression is the series of numbers that have common differences between adjacent values

What is geometric progression?

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Here,
Given a sequence, 1,3,7,15
where first term      A0 = 1
         second term  A1 = 1 + 2 = 3
          third term      A2 = 3 + 4 = 7
From above sequence we can conclude the general term for the sequence as, S = A(n-1) + (A(n-1) + 1)

Thus, the given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.

y^2 + 6y + 9 = 49 factor

Answers

(y+10)(y-4)

Explanation:
In order to solve you must set the equation to 0. Meaning you subtract 49 from 9 to get the original equation to now be y^2+6y-40.
You then set that equation (y^2+6y-40) to zero in order to factor it out.
To do this, you have to find two numbers that multiply to make -40 but add to make 6, which is where you get 10 and -4.

need to solve for x
4x - 2 = 2x + 1

Answers

The answer would be x= 3/2

You would take 2 and add it to the other side leaving 4x by itself, leaving you with the equation 4x= 2x + 3.
Then you would divide both side by 2 giving you 2x= 3. Then you would divide by 2 again to get x=3/2.
Add the 2 to the 1 and then minus 2x from 4x so you get 2x = 3
