The sides of ∆ABC are 30 units, 40 units, and 60 units long. The corresponding sides of ∆XYZ are r times as long as the sides of
san4es73 [151]

Part a) Find the expression that gives the perimeter of ∆XYZ

we know that

Perimeter of triangle ABC is equal to

P=30+40+60\\ P=130\ units

In this problem ∆ABC and ∆XYZ are similar triangles

the scale factor is equal to r

so

scale\ factor=r \\ \\ scale\ factor=\frac{perimeter\ triangle\  XYZ}{perimeter\  triangle\  ABC}  \\ \\ perimeter\ triangle\  XYZ=perimeter\  triangle\  ABC*scale factor\\ \\ perimeter\ triangle\  XYZ=130*r

therefore

the answer Part a) is

The expression that gives the perimeter of ∆XYZ is 130*r\ units

Part b) Find the expression that gives the area of ∆XYZ

we know that

Area\ of\ triangle\ ABC=n\ units^{2}

scale\ factor=r \\ \\ scale\ factor^{2}=\frac{Area\ triangle\  XYZ}{Area\  triangle\  ABC}  \\ \\ Area\ triangle\  XYZ=Area\  triangle\  ABC*scale factor^{2}\\ \\ Area\ triangle\  XYZ=n*r^{2}\ units^{2}

therefore

the answer Part b) is

The expression that gives the Area of ∆XYZ is n*r^{2}\ units^{2}

At a charity fundraiser, each female attendant donated $1,200 and each male attendant donated $800. If the average donation at t
Flauer [41]

The ratio of the number of female attendants to the number of male attendants is 21/17

<h3>Ratio</h3>

  • Amount donated by female attendant = $1200
  • Amount donated by male attendant = $800
  • Average donation = $900

let

  • number of female attendant = x
  • number of male attendant = y

900 = 1200x + 800y / (x + y)

900x + 900y = 1200x + 800y

900x + 1200x = 800y + 900y

2100x = 1700y

x : y = 2100 / 1700

x : y = 21 ; 17

Evaluate p(7,5) can someone help
malfutka [58]
Answer: 2520

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

Work Shown:

P(n,r) = (n!)/((n-r)!)
P(7,5) = (7!)/((7-5)!)
P(7,5) = (7!)/(2!)
P(7,5) = (7*6*5*4*3*2*1)/(2*1)
P(7,5) = (5040)/(2)
P(7,5) = 2520
