They provide all the needed data...

n + d + q = $3.00                           (they provide a ratio) 
3:2:1 = $3.00                                 (let's enter the value of each)
3(.05) + 2(.10) + 1(.25)   
.15 + .20 + .25
.60 = is the value of the ratio   
let's divide the $3.00 by the .60 to get 5
let's now multiply the value of 5 to the ratio and solve the question...

3(5): 2(5): 1(5)
15 nickels
10 dimes
5 quarters

Find the distance between (-7,-2) and (11,3)
jarptica [38.1K]

Answer:

The answer is

<h2>\sqrt{349}  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }   \\</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-7,-2) and (11,3)

The distance between the points is

<h3>d =  \sqrt{ ({ - 7 - 11})^{2} +  ({ - 2 - 3})^{2}  }  \\  =  \sqrt{ ({ - 18})^{2} +  ({ - 5})^{2}  }  \\  =  \sqrt{324 + 25}  \\</h3>

We have the final answer as

<h3>\sqrt{349}  \:  \: units</h3>

Hope this helps you

Find equation of the line passing through the given point in parallel to given equation. write your answer in slope intercept fo
denpristay [2]

Answer:

  • 3) y = (7/2)x -12
  • 4) y = 3x -5
  • 7) y = (1/3)x +4/3
  • 8) y = (-4/3)x +8/3

Step-by-step explanation:

In every case, you can ...

  • replace any constant in the equation by 0
  • for point (h, k), replace x with (x-h) and y with (y-k), then simplify
  • solve for y (add the opposite of the y-term; divide by the y-coefficient)

3) -7(x-4) +2(y-2) = 0 ⇒ -7x +2y +24 = 0

... y = (7/2)x -12

4) (y+2) = 3(x-1)

... y = 3x -5

7) -(x+4) +3(y-0) = 0 ⇒ -x +3y -4 = 0

... y = (1/3)x +4/3

8) 4(x-2) +3(y -0) = 0 ⇒ 4x +3y -8 = 0

... y = (-4/3)x +8/3
