Qrst is a square. pq = 2√ ru = 4
what is the length of su? round to the nearest tenth.

Step-by-step explanation:

step 1

In the isosceles right triangle PQT

PQ=PT ----> because is an isosceles triangle

Applying the Pythagoras Theorem

we have

substitute the values

step 2

In the square QRST

step 3

In the right triangle RSU

Applying the Pythagoras Theorem

we have

substitute the values and solve for SU

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
