Answer:

r=(A/π)^1/2

Step-by-step explanation:

A=πr^2.  When dividing π on both sides, you get r^2 = A/π. Meaning that r = the square root of A/π, or (A/π)^1/2

——. = 3/4
11 - 7


For question 5: input the values of x,y and the gradient into the equation of a line.....

y = mx+ c

-8 = 3(-2) + c

-8 = -6 + c

-2 = c

therefore:

y = 3x - 2

Hope this helps! Any questions let me know :)

a man used $3 to pay for 16 postage stamps. x of them are 15 cents each and the rest are 20 cents each. a) Write down an equatio
Vaselesa [24]

Answer:

Step-by-step explanation:

x = 15 cent stamps

y = 20 cent stamps

I will be using these equations

x + y = 16

0.15x + 0.20y = 3

x = 16 - y

0.15(16 - y) + 0.20y = 3

2.40 - 0.15y + 0.20y = 3

-0.15y + 0.20y = 3 - 2.40

0.05y = 0.60

y = 0.60/0.05

y = 12.......there were 12 twenty cent stamps

x + y = 16

x + 12 = 16

x = 16 - 12

x = 4.....there were 4 fifteen cent stamps

no change is received
