1. The value of y varies inversely with 2. What is the value of k when y = 12.7 and < = 8? O k= 1.5875
O k = 101.6
O k = 20.7
O k= 0.6299

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

answer: an 8-foot rope is tied from the top of a pole to a

stake in the ground, as shown in the diagram

below

step-by-step explanation:

there are infinitely many solutions.
