R is inversely proportional to A. R=12 when A=1.5.
work out the value of R when A=5

R=3.6

Step-by-step explanation:

R=k/A

When R=12, A=1.5

12=k/1.5

k=1.5×12

k=18

To determine R when A =5

R=18/5

R=3.6

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
