Seth needs to buy mulch to cover a circular garden. The garden has a radius of 5ft. Mulch costs $0.25 per square foot. How much will it cost Seth to cover his garden in mulch?

First we need to know the total area. Since this is a rectangle we need two adjacent sides and we can find these from vertex pairing:

Step-by-step explanation:

Matching y: (3,9) --> (5,9) = 2 ft

Matching x: (3,9) --> (3,3) = 6 ft

Area = l*w = 2*6 = 12 square ft

# of bags = 12 sqft/(5sq ft/bag) = 2.4 bags.

Cost = $5.00 * 2.4 = $12   (notice that it cost $1 to cover 1sqft so we could have skipped a step here.)

NOTE: In the real world she probably can't buy just 0.4 of a bag and would actually have to buy three full bags for $15.

Step-by-step explanation:

12x 0.25=?          ?x 5= $?

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
