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

The ticket price for an ice hockey match used to cost £19.60. The price has now increased by 12.5%. How much will 2 tickets cost
Amanda [17]

Answer:

The 2 tickets will cost £44.10 after the increase.

Step-by-step explanation:

First, you have to multiply £19.60 by 12.5% to find the increase in the cost of tickets.

19.60(0.125)=2.45

Add the price increase to the original cost to find the new cost of each ticket.

19.60+2.45=22.05

Multiply the result by 2 since you have to look for the cost of the 2 tickets.

22.05(2)=44.10

Which equation has x=2/3 as a solution and why?
eduard

There are an infinite number of different equations that have
x=2/3  as the solution, or as one of several solutions.

You didn't show us your list of choices, so we can't help you
pick the right one.

Just take each choice, one at a time.  Write ' 2/3 ' in place of 'x'
in each equation, and simplify everything.  You'll wind up with
one equation that's true, and the others will say something that's
nonsense. 

The one that's true is the one that has  x=2/3  as its solution.

Step-by-step explanation:

1.

  • The first pair is adjacent as they have common side.

2.

  • The second pair is vertical as opposite angles of the crossed lines.

3.

  • The third pair has no relationship with each other, so neither is the answer.
