Can somebody me with the math's questions on pythagoras theorem?

2.4 cans cost 47.4

If you cannot buy 2.4 cans, you must buy 3 cans, then you'll pay 59.25

Step-by-step explanation:

The lawn has trapezoidal shape, so find the area of the trapezoid using formula

In the diagram, ABED is rectangle, so BE = 12 m, thus ED = 20 m - 12 m = 8 m.

Consider right triangle EDC. By the Pythagorean theorem,

Thue,

Height = 15 m

Find the midline:

Hence,

One can cover to cover is needed

cans

One can costs 19.75, so 2.4 cans cost

If you cannot buy 2.4 cans, you must buy 3 cans, then you'll pay

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
