B would be your answer because the chart says 1 shirt equals $25 dollars, 2 shirts equal $40 and 3 shirts equal 55 dollars. On the graph (B) if you find your number of shirts (x) and look up at the line and see that it is in line (y) with the cost that is how u find ur answer. Hope this helped!

<h3>Answer:   10*sqrt(30)</h3>

That is the same as writing 10\sqrt{30}

======================================================

Explanation:

The diagram shows that

  • AC = 60
  • AD = 50

That must mean DC = AC-AD = 60-50 = 10

We'll use this to help find BD as shown below

AD/BD = BD/DC

AD*DC = BD*BD .... cross multiply

(BD)^2 = AD*DC

BD = sqrt(AD*DC) ..... geometric mean formula

BD = sqrt(50*10)

BD = sqrt(500)

----------------------

Now apply the pythagorean theorem to find AB. Focus on triangle ABD.

(AD)^2 + (BD)^2 = (AB)^2

(AB)^2 = (AD)^2 + (BD)^2

(AB)^2 = (50)^2 + (sqrt(500))^2

(AB)^2 = 2500 + 500

(AB)^2 = 3000

AB = sqrt(3000)

AB = sqrt(100*30)

AB = sqrt(100)*sqrt(30)

AB = 10*sqrt(30)

The sum of four consecutive whole numbers is 230.Find the numbers.
taurus [48]

<span>х is the first number
(x + 1) is the second number
(x + 2) is the third number
(x + 3) is the fourth number
</span>
x + x+1 + x+2 + x+3 = 230
4x + 6 = 230
4x = 230 - 6
4x = 224
x = 224/4
x = 56  the first number 
56 + 1 = 57   the second number 
56 + 2 = 58 the third number 
56 + 3 = 59 the fourth number

Answer: 56, 57, 58, 59.

Helppp plsss. i have to turn this in asap
Lady bird [3.3K]

Answer:

y= 2x-5

Step-by-step explanation:

The slope formula is m=(y2-y1)/(x2-x1)

-3-1 / 1-3 = -4/-2= 2=m

The Y interception- y=mx+b using coordinates (3,1)

1=2(3)+b

1=6+b (subtracting 6 on both sides to isolate b)

-5=b

plug it in

y=2x-5

Approximately how many red candies will be in the packages?
galben [10]
This one is kinda tricky, 

So if we look at the clues, 1 and 2 represent red candies. 

We need to think like a computer here, if we were scanning a bar code with our laser eyes and we see 1s and 2s as favorable in this case, we would see 5 favorable codes (there are 3 "1s" and 2 "2s"), 

Therefore the answer should be 5. 

Hope this helped.
