Answer:

  • 2–9  7π/6
  • 3–7  2π/3
  • 4–6  π/3
  • 1–4  π/2
  • 5–10  5π/6

Step-by-step explanation:

The angle between numbers on an analog clock is π/6 radians. So, the angles of interest are ...

  2 to 9 : seven numbers : 7π/6 radians

  3 to 7 : four numbers : 4π/6 = 2π/3 radians

  4 to 6 : two numbers : 2π/6 = π/3 radians

  1 to 4 : three numbers : 3π/6 = π/2 radians

  5 to 10 : five numbers : 5π/6 radians

Solve If QR = 6x + 1, PR = 14x - 13, and PQ = 5x - 2, find PR
solong [7]

Answer:

P____Q____R

PR= PQ+ QR

(14x-13) = (5x-2)+(6x+1)

14x-13= 11x – 1

14x – 11x = 13–1

3x = 12

x= 12/ 3

x= 4

PR= 14x – 13 = 14 (4) – 13 = 18 – 13= 5

If you want (PQ , QR ) this is the solution

PQ =5x-2=5(4)-2=20-2=18

QR =6x+1=6(4)+1=24+1=25

I hope I helped you^_^

part of the river she observed fell 1.68 millimeters per year for 1.5 years. Use the distributive property to calculate the exac
Alecsey [184]
1.68 mm per year for 1.5 years could be rewritten as 
(2.00-0.32) mm per year for 1.5 yrs.

Multiply:  (1.5 yrs)(2.00-0.32)(mm/yr) = 3 mm + 0.48 mm = 3.48 mm

This approach makes use of the distributive property of multiplication.

-2x-9y=-25 -4x-9y=-23
goldfiish [28.3K]
So to start this off you would add 9y to both sides of the equation and then you regroup it which gives you <span>−2x=−25+9y and then you regroup the terms and get -2x=9y-25 and then you dived both sides by -2 and get x=9y-25/-2 then you simplify and so on 

but at the end you should get x=-1 and y =3
