The area of a rectangular wall of a barn is 72 square feet. Its length is 10 feet longer than twice its width. Find the length and width of the wall of the barn.

Answer:

one equation would be S+ L=36for the number of shirts sold.

Answer: 64 short-sleeved shirts were purchased.

Step-by-step explanation: (x = short-sleeved shirts. y = long-sleeved shirts.)  

x + y = 100

10x + 12y = 1072

—12(x + y = 100) >>> -12x - 12y = -1200                                                                                                           10x + 12y = 1072 (add the equations and cancel out the 12y)

-2x/-2 (-2 cancels out) = -128/-2   (divide both by -2)

x = 64 shirts purchased for $10 each.   (Hope this helped!)

(vvvThis next part doesn’t answer the question, but I should finish the equation.)

(Plug in 64 for x)>>> 64 + y = 100 (then, subtract 64 from both sides) >>> 64 - 64 = 0 (they cancel out) and 100 - 64 = 36

y = 36 shirts purchased for $12 each.

I really hope this helped! :)

Answer:

Blue = 12/58 * 100% = 20.68 = 21%

Red = 6/58 * 100 = 10.34 = 10%

Yellow = 21/58 * 100 = 36.20 = 36%

Black = 8/58 * 100 = 13.79 = 14%

Green = 11/58 * 100 = 18.96 = 19%

Step-by-step explanation:

Given the table :

Marble_color ____ Number of marbles

Blue ___________ 12

Red ___________ 6

Yellow _________ 21

Black __________ 8

Green _________ 11

Theoretical probability % = (number of favorable outcome / number of total possible outcomes)

Total possible outcomes = (12+6+21+8+11) = 58

Blue = 12/58 * 100% = 20.68 = 21%

Red = 6/58 * 100 = 10.34 = 10%

Yellow = 21/58 * 100 = 36.20 = 36%

Black = 8/58 * 100 = 13.79 = 14%

Green = 11/58 * 100 = 18.96 = 19%

Answer:

a. $28,800

b. $16,000

Step-by-step explanation:

A.

20,000 * 20% = 4,000

so thats how much more it will be next year

add that together

20,000 + 4,000 = 24,000

so thats one year from now and we have to find two

multiply 20% times next years value

24,000 * 20% = 4,800

so add that to 24,000

24,000 + 4,800 = 28,800

so in two years the value will be $28,800

B.

20,000 * 20% = 4,000

so thats how much less it was worth one year ago

so you have to subtract it

20,000 - 4,000 = 16,000

so it was worth $16,000 one year ago

whats the question?

Step-by-step explanation:

Answer:

They might can run to the end together, or one go to the end first.

Step-by-step explanation:

The dog can run fast.

The cat can jump fast.

If the dog or cat one is fat, the the other will get to the end first, if they both fat or both not fat, then they might get to the end together.

Answer:So, since it is continuously, we need to think of PERT

A=P\times e^{rt}

So, we just plug our numbers in to solve for T

8000=4000e^{.07t}\\\ln(8000)=\ln(4000e^{.07t})\\\ln(8000) = \ln(4000) + \ln(e^{.07t})\\\ln(8000)=\ln(4000)+.07t\ln(e)\\\ln(8000)=\ln(4000)+.07t\\\frac{\ln(8000)}{\ln(4000)}=.07t\\\frac{\ln(8000)}{.07\ln(4000)}=t\\ 15.479=t

It will take 15.479 years

Answer:

You will need 800 [tex]ft^{3}[/tex] of water to fill the pool.

Step-by-step explanation:

The amount of cubic that we need is equal to the volume of the pool therefore we just have to find the volume of the pool by using the following formula...

Volume = (Length)(Width)(Height/Depth) = (20)(10)(4) = 800

Therefore you will need 800 [tex]ft^{3}[/tex] of water to fill the pool.

Answer:

Step-by-step explanation:

The following equation y=f(x+3) can be seen graphed in the image attached to this answer. The point P(-6,-2) shows up if we input -6 as the variable x which will output -2 as the value for y. This can be seen in the graph below.

y=f(x+3)

y= -6 + 3

y = -2

Step-by-step explanation:

substitute the values

px=3x+1

=(3x+1)/x

=3x/x +1/x

=3+1/x

rx=2x²+5

p(r(x)) =(3+1/x(2x²+5))

=6x²+15+2x²/x+5/x

=3(2x²+5)+1/x(2x²+5)

=(2x²+5)(3+1/x)

Step-by-step explanation:

Opposite angles in a quadrilateral will add up to 180, so:

[tex]95 + 7x + 1 = 180\\and \\4y + 14 +7y+1=180[/tex]

Solving each:

[tex]95+7x+1 = 180\\7x + 96 = 180\\7x = 84 \\x = 12[/tex]

and:

[tex]4y+14 + 7y + 1 = 180\\11y + 15 = 180\\11y = 165\\y = 15[/tex]

Answer: You didn't add like a question or a link sorry..

P= Total # of people who entered the park

t= The time in hours

P=2200t

6600 = 2200t

Divide both sides of the equation by 2200:

3=t

answer : 3 hours

9515 1404 393

Answer:

  2 8/11 hours ≈ 2.73 hours

Step-by-step explanation:

Assuming a constant rate, entries are proportional to time.

  time/people = 1 h/(2200 people) = t/(6000 people)

  t = (1 h)(6000/2200) = 2 8/11 h ≈ 2.73 h

It will take about 2.73 hours for 6000 people to enter.
